Description

  The present invention includes a variable display unit capable of variably displaying a plurality of types of identification information each identifiable. After the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. The present invention relates to a slot machine capable of generating a winning according to the display result.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels having a plurality of types of symbols as identification information drawn on the outer periphery, and each reel has a start lever by a player. Rotation is started by operating, and when the player operates a stop button provided corresponding to each reel, the rotation is stopped within a range of a predetermined maximum delay time from the operation timing. . A winning is generated according to the display result derived when the rotation of all reels is stopped.

  The types of winning combinations include small roles, special roles, and re-playing roles. Here, in the winning of a small role, the player can obtain a profit that a predetermined number of medals are paid out for each type of small role. In the special role winning, the player can obtain a profit that the next game is shifted to a gaming state advantageous to the player, such as a regular bonus or a big bonus. In the winning of the re-gamer, it is possible to obtain a profit that the next game can be performed without consuming new medals for setting the number of bets.

  In order for winning of each combination to occur, generally, it is a condition that a winning is made by an internal lottery performed in advance (usually when the start lever is operated). In addition, the combination of symbols constituting the winning combination in the internal lottery is aligned with the effective line, and the combination of symbols configuring the winning combination not selected in the internal lottery is not aligned with the effective line. Reel control is performed.

  In such a slot machine, if the occurrence of a specific winning is permitted while being controlled to an advantageous state, whether or not to grant a privilege to extend the period during which it is controlled to an advantageous state There is one that raises the probability of winning the grant lottery when the lottery is performed and the grant lottery is not won (for example, Patent Document 1).

JP 2013-158497 A

  In the slot machine of Patent Document 1, even when it is determined that no privilege is granted when the occurrence of a specific winning is permitted, the slot machine can be shifted to an advantageous state in which the winning probability of the grant lottery is high. Therefore, even if it is decided not to grant a privilege, it can amplify the expectation that the subsequent occurrence of a specific prize is allowed, so that it is possible to improve the interest of the game after the privilege is not granted did it. However, in that case, in addition to the process of determining whether or not to grant a privilege, the process of determining whether or not to shift to an advantageous state is also performed, which increases the processing load.

  The present invention has been conceived in view of such circumstances, and its purpose is to allow the generation of a specific prize and to reduce the processing burden when it is determined not to grant a privilege, and to the subsequent game. It is to provide a slot machine that can improve interest.

(1) Provided with a variable display unit capable of variably displaying a plurality of types of identification information each capable of being identified,
In the slot machine (for example, slot machine 1) in which a winning result can be generated according to the display result after the variable display portion is variably displayed, the display result is derived by stopping the variable display of the variable display portion.
A pre-determining means (for example, an internal lottery process) for determining whether or not to allow a prize to be generated;
A privilege grant determining unit that determines whether or not a privilege (for example, the number of AT games) is granted based on the fact that the occurrence of a specific winning is permitted by the prior determination unit (for example, winning a strong cherry). (For example, extra lottery processing)
State control means (for example, a main state) for controlling to any one of a plurality of types of states including a first state (for example, a low-accuracy state) and a second state (for example, a high-accuracy state) more advantageous than the first state Control unit 41);
A first effect (for example, an effect for displaying the first background) that suggests the first state, and a second effect (for example, an effect for displaying the second background) that indicates the second state. Production control means (for example, sub-control unit 91) capable of executing
The state control means controls the first state or the second state over a predetermined period (for example, a period until one navistock is consumed), and shifts the state to another state during the predetermined period. (For example, until one Navistock is digested, neither high accuracy state nor low accuracy state is transferred to another state)
The production control means includes
Even in the second state, the first effect can be executed (for example, as shown in FIG. 19B, the first background is selected with a probability of 50% even in the highly accurate state). ,
When the first effect is executed in the second state and the privilege grant determining means determines not to grant the privilege, the first effect can be switched to the second effect (for example, As shown in FIG. 20C, even when the first background is displayed in the high-accuracy state and the winning lottery is not won, the background is switched to the second background with a probability of 50%.) .

  According to such a configuration, the occurrence of a specific winning is allowed and the current state is not shifted to another state for a predetermined period when it is determined not to grant a privilege. Compared with the case of making a decision, the processing burden associated with such a decision can be reduced. However, although the state is not changed, the effect can be improved because the effect can be switched from the first effect to the second effect suggesting the second state.

(2) In the slot machine according to (1) above,
The privilege granting unit determines whether or not to grant the privilege based on the fact that the predetermined determination different from the specific winning is permitted by the prior determination unit (for example, winning a strong watermelon) And
The probability that the privilege is granted based on the occurrence of the specific winning is equal to the probability that the privilege is granted based on the occurrence of the predetermined prize (for example, FIG. 17). As shown in the above, in both cases, when winning a strong cherry and winning a strong watermelon, the winning is won with the same probability.)

  According to such a configuration, when the occurrence of the specific prize is permitted and when the occurrence of the predetermined prize is permitted, the probability that the privilege is granted is equal, and therefore, when the occurrence of the specific prize is permitted. It is possible to unify the control with the time when the predetermined winning is permitted.

(3) In the slot machine according to (1) or (2) above,
Setting value setting means (for example, main value) for setting any setting value among a plurality of types of setting values (setting values 1 to 6) having different ratios for determining whether or not winning is permitted A control unit 41),
The pre-determining means allows the occurrence of the specific prize at a predetermined rate regardless of the set value (the winning probability does not change regardless of the set value for strong cherry, strong watermelon, weak cherry, and weak watermelon). .

  According to such a configuration, since the rate at which the specific prize is allowed is equal regardless of the set value, the ratio at which the specific prize is allowed is changed for each set value when designing the specification. There is no need to do so, and the work load during design can be reduced.

(4) In the slot machine according to any one of (1) to (3) above,
The production control means, when executing the first production in the first state, when the privilege grant determining means decides not to give a privilege, the first production to the second production Switching is possible (for example, see the column of “Background switching” in the modification).

  According to such a configuration, even when the first effect is being executed in the first state, it is possible to switch to the second effect, and thus suggesting that the second state is also present in the first state. Yes, the fun of gaming is improved.

(5) In the slot machine according to any one of (1) to (4) above,
The production control means, when executing the first production in the second state, when the privilege grant determining means decides to give a privilege, the first production to the second production (For example, as shown in FIG. 20C, when the first background is displayed in the high-accuracy state and the winning lottery is won, the background is set to the second background with a probability of 80%. Switch to.)

  According to such a configuration, even if it is determined to give a privilege in the second state, it can be suggested that the state is the second state, so that the interest of the game is improved.

(6) In the slot machine according to any one of (1) to (5) above,
In the second state, the privilege granting means determines to give the privilege with a higher probability than in the first state (for example, as shown in FIG. 17, the privilege granting unit is controlled to a highly accurate state. The time is more likely to win the lottery with a higher probability than when the low probability state is controlled.)

  According to such a configuration, the interest rate of the game is improved because the proportion of the privilege given varies depending on the state.

(7) In the slot machine according to any one of (1) to (6) above,
As the specific prize, there are a first specific prize (for example, weak cherry) and a second specific prize (for example, strong cherry),
When the occurrence of the second specific prize is permitted, the privilege granting unit determines to grant the privilege with a higher probability than when the first specific prize is permitted (for example, As shown in FIG. 17, when a strong cherry is won, a lottery is won with a higher probability than when a weak cherry is won.)

  According to such a configuration, since the ratio of the bonus granted varies depending on the type of the specific winning that is permitted to generate the winning, the interest of the game is improved.

  A mode for carrying out a slot machine according to the present invention will be described below based on examples. In the following embodiments, an example in which the present invention is applied to a slot machine will be described. FIG. 1 is a front view showing the overall structure of the slot machine 1 according to the present embodiment. The slot machine 1 includes a housing 1a having an open front surface and a front door 1b pivotally supported on a side end of the housing 1a. A liquid crystal display 51 is provided at the upper center of the front door 1b. The liquid crystal display 51 has a display area 51a, and the transmission area 51b corresponding to the see-through window 3 can be transmitted. Accordingly, a predetermined effect can be executed in the display area 51a, and the reels 2L and 2C arranged in parallel inside the housing 1a through the transparent window 3 through the transmission area 51b of the display area 51a. 2R (hereinafter also referred to as a left reel, a middle reel, and a right reel) becomes visible. FIG. 2 is a diagram showing a symbol arrangement of each reel. On the reels 2L to 2R, a plurality of types of symbols that can be identified are arranged in a predetermined order. The number of reels is not limited to three, and may be one or two or more. Moreover, although the variable display part has shown the example comprised by the physical reel, you may be comprised by image display apparatuses, such as a liquid crystal display.

  At the lower right of the liquid crystal display 51, a medal insertion portion 4 into which medals can be inserted is provided, and at the lower part of the front door 1b, a medal payout opening 9 through which medals are paid out and speakers 53, 54 are provided.

  As an example of operation means, the front door 1b has a predetermined number of bets determined according to the gaming state within a credit range stored as a gaming value (medal number) owned by the player. The MAXBET switch 6 operated by the user, the settlement switch 10 operated when the credit and the set bet number are settled and returned, the start switch 7 operated when starting the game, and the rotation of the reels 2L to 2R. Stop switches 8L, 8C, and 8R that are operated when stopping each, an effect switch 56 for use in effects, and the like are provided.

  The front door 1b is provided with a game display unit 13 for notifying information related to a game as an example of a notification unit. The game display unit 13 displays a credit indicator 11 that displays the number of medals stored as credits, a medal payout number, an error code at the time of error, information that can identify the stop order of reels, and the like. The game auxiliary display 12, 1 BETLED 14 for informing the set bet number, 2 BETLED 15, 3 BETLED 16, the insertion request LED 17 for informing that a medal can be inserted, and the start switch 7 can be operated to start the game. Waiting for the start of the rotation of the reels 2L, 2C, and 2R because a certain period of time has not elapsed since the start of the previous game since the start valid LED 18 and the start switch 7 have been operated. LED 19 during wait to notify that, replay after replay winning Replay During LED20 indicating that a being arm is provided.

  When playing a game in the slot machine 1, first, a predetermined number of bets (for example, 3) are set by inserting medals into the medal insertion unit 4 or operating the MAXBET switch 6. As a result, the winning line LN becomes valid, the operation to the start switch 7 becomes valid, and the game can be started. If medals are inserted with the bet number set, the amount is added to the credit.

  The winning line is a line for determining whether a combination of symbols displayed on the see-through windows 3 of the reels 2L to 2R is a winning symbol combination. In the present embodiment, an example in which only one winning line LN is provided will be described. However, a plurality of winning lines may be provided. In addition, invalid lines LM1 to LM4 are provided to make it easy to recognize that the combination of symbols constituting the winning line is aligned with the winning line LN. The invalid lines LM1 to LM4 are not determined as winning lines, but when a combination of specific winning symbols (so-called disparity) is aligned on the winning line LN, any of the invalid lines LM1 to LM4 has a predetermined symbol. By aligning the combinations (for example, bell-bell-bell), it is easy to recognize that a combination of symbols constituting a specific prize is arranged on the winning line LN.

  When the start switch 7 is operated in a state where the game can be started, the reels 2L to 2R are rotated to display the symbols variably, and when the stop switches 8L to 8R are operated, the rotation of the corresponding reel is stopped. The three symbols are derived and displayed as display results on the upper, middle, and lower stages of the fluoroscopic window 3. When a combination of winning symbols stops on the winning line LN and a winning occurs, a predetermined number of medals are given to the player according to the winning and the credit is added or the credit reaches the upper limit (50). In this case, medals are paid out from the medal payout exit 9.

  Here, in the narrow sense, “game” in the slot machine 1 refers to a period from when the start switch 7 is operated to when the reels 2L to 2R are stopped. Since the number is set, the medals are paid out and the game state is shifted after the reels 2L to 2R are stopped, these incidental processes are also included in the “game” in a broad sense.

  FIG. 3 is a view showing the internal structure of the slot machine 1. FIG. 4 is a diagram illustrating a functional configuration example of the slot machine 1. In the example of FIG. 4, a game control board 40 that controls the progress of the game and outputs various commands according to the progress of the game, an effect control board 90 that controls a predetermined effect according to the command, and a drive power source for the electrical components A power supply board 101 for generating a signal and an external output board 1000 for outputting a signal according to the progress of the game to the outside are provided.

  The game control board 40 advances the game based on detection signals from switches such as various operation means and detection means (illustrated on the left side of the game control board 40 in FIG. 4), and notifies means (game control in FIG. 4). Display devices such as the example on the left side of the substrate 40 are driven and controlled. Further, the game control board 40 drives and controls the reel motors 32L to 32R based on signals from the reel sensors 33L to 33R.

  A circuit configuration (illustrated in the game control board 40 in FIG. 4) such as the main control unit 41 is mounted on the game control board 40. The main control unit 41 performs processing related to the progress of the game, and directly or indirectly controls the configuration mounted on or connected to the game control board 40. The main control unit 41 is a one-chip microcomputer and includes a CPU, a ROM, a RAM, an I / O port, and the like.

  The effect control board 90 is connected to an effect switch 56 and drives and controls an effect device such as the liquid crystal display 51 (illustrated on the left side of the effect control board 90 in FIG. 4). The effect control board 90 is mounted with a circuit configuration such as the sub-control unit 91 (illustrated in the effect control board 90 of FIG. 4). The sub-control unit 91 receives a command transmitted from the game control board 40, performs a process of performing an effect, and directly or indirectly controls a configuration mounted on or connected to the effect control board 90. The sub-control unit 91 is a one-chip microcomputer and includes a CPU, a ROM, a RAM, an I / O port, and the like. The circuit configuration of the sub-control unit 91 includes, for example, a clock device 97 (hereinafter also referred to as RTC) for measuring at least one of date and time. The sub-control unit 91 can execute effect control according to, for example, at least one of the date and time counted by the RTC 97, a detection signal from the effect switch 56, and the like. A hopper motor 34b, various operation means and detection means (illustrated on the right side of the power supply board 101 in FIG. 4) and the like are connected to the power supply board 101.

  FIG. 5 is a diagram for explaining the technical matters related to the types of winning combinations, the symbol combinations of winning combinations, and winning combinations. The name column indicates the name of the winning combination, and the symbol combination column indicates the combination of symbols in which the winning combination becomes a winning. In addition, in the symbol combination column that is aligned with the invalid line, a symbol combination that is easy to be recognized by the player and is a combination of symbols that stop on the invalid line when the winning symbol combination stops on the winning line. Yes. In the payout number column, values (medal payout, replay grant) given at the time of winning are shown. BB1 and BB2 are winning combinations with a transition to an advantageous state of bonus. In the BB1 and BB2 payout number columns, bonus termination conditions to be transferred by winning are shown. Each bonus is ended by paying out more than a predetermined number of medals. For example, a bonus controlled by winning / winning BB1 ends in a game in which the number of medals paid out during the bonus is 351 or more.

  FIG. 6 is a diagram for explaining a part of the transition of the gaming state controlled by the main control unit 41. The game state column shows the game state to be transferred when winning. “/” Indicates “or”. For example, the symbol combination of the fall replay in FIG. 6 is “Bell-Replay-Bell”, which is controlled by RT1 at the time of winning, and the value to be given is replay grant. When the symbol combination of the fall replay stops on the winning line, “Replay / Plum-Replay-Replay / Plum” stops on the invalid line. When the special replay symbol combination stops on the winning line, “black BAR / white BAR−black BAR / white BAR−black BAR / white BAR” stops on the invalid line. "Black BAR / White BAR-Black BAR / White BAR-Black BAR / White BAR" can be stopped on the invalid line only when the special replay is won, and when the special replay is not won It is a combination of symbols that is not stopped on the line.

  The replaying role (replay) is a role for giving a replaying. Here, the re-game means that the next game can be performed without using the game value (for example, credit) owned by the player. In other words, the re-game is a game in which the reel 2 (variable display unit) can be variably displayed without using the game value owned by the player. In the present embodiment, when a re-game player is won, a prize is won regardless of the operation procedure (at least one of the operation order and operation timing) of the stop switch 8 (derivation operation means). Even if the re-game combination is won, depending on the operation procedure of the stop switch 8 (derivation operation means), it may be a combination that does not win (that is, a combination that has been missed).

  FIG. 7 is a diagram showing a symbol combination of the transition outcome. FIG. 8 is a diagram for explaining the transition of the gaming state controlled by the main control unit 41, and FIG. 9 is a diagram showing an outline of the gaming state and RT. As shown in FIG. 8, the slot machine 1 in the present embodiment has RT0 to RT4 in which replay is won with a predetermined winning probability (see the numerical value in the re-playing role column in the upper diagram of FIG. 9), and the winning probability of the small role is Among a plurality of types of gaming states including bonuses that are improved more than during RT0 to RT4, the game state is controlled to one of the corresponding gaming states from when the start condition is satisfied until the end condition is satisfied (FIG. 8). Refer to the winning combination or the outcome shown along the arrow in FIG. 9, refer to the start condition / end condition column in the upper diagram of FIG. 9).

  Of RT1 to RT4, RT1 and RT3 are both disadvantageous for a player who has a low medal payout rate. On the other hand, both RT0 and RT2 are gaming states that are advantageous for a player with a high medal payout rate. In particular, RT2 is a gaming state that has a higher medal payout rate than RT0 and is more advantageous to the player. RT4 is a gaming state that shifts when a bonus is won. In RT0 to RT4, the probability of winning a small combination that is a lottery target combination other than the re-game combination is set so as not to change.

  When either BB1 or BB2 is won, RT4 is controlled. The winning flag that is set when either BB1 or BB2 wins is carried over until winning of the winning BB occurs. Also, RT4 is controlled continuously from BB winning to BB winning. In the next game after the end of the BB winning game, a winning suggestion effect is executed to notify that BB is won, and the player can grasp that BB1 or BB2 has been won. During RT4, it is lower than during RT0 and RT2, and wins the replay with the same probability as during RT1 and RT3 (refer to the numerical value in the replaying role column in the upper diagram of FIG. 9). Note that the replay probability in RT4 is set to a probability that the payout rate does not exceed 1 even if the winning combination can be won without being missed. In other words, the replay probability in RT4 is the total number of medals to be paid out when winning a winning combination without losing the winning combination during RT4. The total number of medals is not exceeded and the probability that the medals will not increase is set. When a BB win occurs during RT4, the bonus is controlled, and the bonus is ended by paying out more than the number of medals described with reference to FIG. 5, and the process is controlled to RT3. The types of replays to be internally drawn are determined for each RT type (circles in the lower diagram of FIG. 9 indicate replays to be drawn).

  In addition, when BB is winning simultaneously with the other lottery target combination, reel control is performed so that the lottery target combination other than BB wins preferentially. For this reason, when the probability of winning a small combination or re-playing combination in RT4 is high, it is difficult for a BB winning to occur and it is difficult to shift to a bonus. Therefore, in RT4, the probability of winning the re-gamer is set to be lower than RT0 or RT2 (see FIG. 9). Thereby, in RT4, it is easy to win BB alone, and it is difficult to occur that it is not possible to shift to a bonus indefinitely.

  As shown in FIG. 8, the process proceeds to RT0 to RT3 depending on the outcome. The gaming state immediately after the setting change for setting the winning combination winning probability is RT3. Transition from RT3 to RT1 is made by derivation of the transition event. The transition outcome is one of the outcomes shown in FIG. In these transitions, the left bells 1 to 4, the middle bells 1 to 4, and the right bells 1 to 4 shown in FIG. And, if the top bell that has been won is missed, it is an outcome that matches the winning line LN.

  The transition from RT1 to RT0 is made by winning the promotion replay. The outcome of the promotion replay is one of the combinations of the symbols of promotion replays 1 and 2 shown in FIG. The transition from RT0 to RT2 is made by special replay winning. The outcome of the special replay is one of the combinations of special replay symbols shown in FIG. When a transition outcome appears in RT2, it returns to RT1. Further, when a transition outcome appears at RT0 or a fall replay wins, the process returns to RT1.

  Therefore, the player needs to pay attention to the outcome in order to stay in the current advantageous gaming state or shift to a more advantageous state. However, which of the promoted replay, special replay, and falling replay is derived depends not only on the internal winning situation but also on the stop order of the reels 2L, 2C, 2R. That is, whether or not the current advantageous gaming state can be maintained, a transition to a more advantageous state, or a falling to an unfavorable gaming state is determined by the pressing order of the stop switches 8L, 8C, and 8R. The slot machine according to the present embodiment has a function of notifying the pushing order that is advantageous to the player. Such an effect for notification is called a navigation effect. The period during which the navigation effect is performed is called assist time (AT). The AT is an example of a state that is advantageous to the player.

  Here, the flow of the game in RT0 to RT3 will be described. After completion of the setting change state, it is controlled by RT3. The setting change state means a state in which the set value of the winning rate for winning combination can be changed. In the slot machine 1, the setting value of the winning rate can be changed by operating a setting key switch (not shown). In RT3, it becomes non-AT and the navigation effect is not executed. For this reason, if one of the bells such as the left bell 1 to 4 is elected at RT3, a transition outcome is derived depending on the timing of the second stop and the third stop (see FIG. 14), and the gaming state is changed to RT1. Transition. In RT1, the game proceeds to RT0 by winning the promotion replay. In order to win the promotion replay, it is necessary not only to win the replays GR1 to GR6 (see FIG. 13) corresponding to the promotion replay, but also the reel 2L by the operation procedure predetermined for each combination (see FIG. 13). , 2C, 2R need to be stopped.

  Even if controlled to RT0, if a transition outcome appears or a fall replay occurs, it will return to RT1. In RT0, when the replay GR11-13 is won (see FIG. 11), the fall replay wins with a probability of 2/3 (see FIG. 13) unless the push order to avoid the fall replay is known. Care should also be taken to avoid transition outcomes. When one of the bells such as the left bells 1 to 4 is elected, when the first reel other than the predetermined reel (reel for lowering the right lowering bell or middle bell shown in FIG. 14) is stopped for the first time, the second Depending on the timing of the stop and the third stop, the transition outcome is derived.

  In order to be promoted from RT0 to RT2, it is necessary to derive a special replay. At RT0, there is a possibility that replays GR21 to 23 will be won (see FIG. 11 and FIG. 13). At this time, if a predetermined reel (reel for winning the special replay shown in FIG. 13) is first stopped, Replay can be awarded and promoted to RT2. However, in RT2, it is necessary to pay attention to the transition that triggers the downgrade to RT1. When one of the bells such as the left bells 1 to 4 is elected, the second stop is performed when the reels other than the predetermined reel (reel for lowering the right lowering bell or middle bell shown in FIG. 14) are stopped for the first time. Depending on the timing of the third stop, the transition outcome is derived. As a result, most of the games during non-AT are digested at RT1.

  AT has a great influence on the transition of these gaming states. In RT1, when one of the replays GR1 to GR6 is won (see FIG. 13), a navigation effect for winning the promoted replay can be executed. For this reason, by performing a stop operation according to the navigation effect, it is possible to win the promotion replay and shift to RT0. In RT0, when one of the replays GR11 to 13 is won (see FIG. 13), a navigation effect for winning a normal replay can be executed. For this reason, RT0 can be maintained by normal replay winning by performing stop operation according to a navigation effect. In addition, in RT0, when one of the left bell 1 to 4, the middle bell 1 to 4, and the right bell 1 to 4 is won, the operation procedure for winning the right falling bell or the middle bell is specified. The navigation effect is executed. Therefore, by performing the stop operation according to the navigation effect, it is possible to avoid derivation of the transition outcome and maintain RT0. Furthermore, at RT0, when any of the replays GR21 to 23 (see FIG. 13) is won, a navigation effect for specifying an operation procedure for winning a special replay can be executed. For this reason, by performing a stop operation according to the navigation effect, it is possible to shift to RT2 by special replay winning.

  In RT2, when one of the left bell 1 to 4, the middle bell 1 to 4, and the right bell 1 to 4 is won, the navigation for specifying the operation procedure for winning the right falling bell or the middle bell Production is performed. For this reason, by performing the stop operation according to the navigation effect, it is possible to avoid the derivation of the transition outcome and maintain RT2.

  Thus, since the navigation effect is executed so that it is controlled by RT2 and maintained at RT2 when it is during AT, most of the games during AT are consumed at RT2. Will be. The AT ends when the number of AT games becomes zero. The number of AT games is controlled to be RT2 + AT (in this embodiment, the state controlled by AT in RT2 advantageous to the player is particularly referred to as assist replay time (hereinafter referred to as ART)). Counting is started from the next game after the game that has become possible, that is, the game after winning one of the replays GR21 to 23 at RT0 and winning special replay. As a result, when the game for the number of AT games is substantially digested by ART, AT ends. Then, ART ends when AT ends.

  After the ART is finished, the navigation effect is not executed, but the control to RT2 is maintained until the transition outcome is derived. However, during RT2 after the end of ART, since it is non-AT, the first reels other than the predetermined reel (reel for lowering the right bell or middle bell shown in FIG. 14) are first stopped as described above. The As a result, during RT2 after the ART is finished, the transition is stopped at an extremely early stage after the ART is finished, so that the transition is made to the RT1.

  FIG. 10 and FIG. 11 are diagrams showing combinations of lottery object combinations that are read out as lottery object roles (hereinafter also referred to as winning combinations) for each gaming state. The lottery target role column indicates the name, and the game status column indicates that the lottery target role is subject to lottery for each RT type, and the winning probability is indicated by the numerical value under the circle. The number of judgment values involved is indicated. For example, the bell is a lottery target winning combination in 360/65536 in any state of RT0 to RT3. During RT4, bonus lottery is not performed, but the winning combination of the winning combination that can be won at the same time as the bonus (hereinafter also referred to as simultaneous winning combination) is the same probability as during other RTs. For weak watermelons, an internal lottery is performed with the number of judgment values shown in parentheses.

  As shown in FIG. 11, the special replay is determined to be a lottery target only when controlled by RT2. Further, in the bonus, for example, the middle bell is set as a lottery target and it is determined to win with an extremely high probability (64000/65536). The middle bell is a role that can generate a prize regardless of the operation timing. For this reason, during the bonus, regardless of the operation timing and operation procedure, the middle bell prize can be generated with a very high probability, and the number of medals can be increased efficiently. For this reason, the bonus is an advantageous state for the player.

  FIG. 12 is a diagram illustrating combinations of winning combinations included in a lottery target combination. For example, the weak cherry is the lower cherry. The weak watermelon includes a right-down watermelon, an upper watermelon, and a middle watermelon. Therefore, when the weak watermelon is won in the internal lottery, it means that the right-down watermelon, the upper watermelon, and the middle watermelon are won.

  Among the lottery target combinations, bonus 1 to bonus 12 are combinations that can be won by simultaneously reading out a predetermined winning combination such as BB1 or BB2 and weak cherry or bell. Also, as shown in FIG. 10, different numbers of determination values are defined for bonus 1 to bonus 12. For this reason, the bonus 6 or 12 is the advantage for the player, that is, the ratio of BB1 or BB2 actually winning simultaneously when winning the simultaneous winning combination (hereinafter also referred to as reliability). The number of determination values is determined so that the middle cherries are the highest, followed by strong cherries, strong watermelons, weak cherries, and weak watermelons in this order, and the bell (hereinafter also referred to as the middle tier bell) is the lowest.

  13 and 14 are diagrams for explaining reel control when a plurality of winning combinations are simultaneously won. When a winning operation is performed in the pressing order shown in the pressing order column for each winning lottery object, the reel control is performed to stop the winning symbol combination shown in the symbol combination to be stopped on the winning line LN. For example, when the replay GR1 is won, the promotion replay 1 is derived when the pressing order is left middle right, and the normal replay is derived when the pressing order is other than left middle right. Also, for example, when the left bell is elected, if the pushing order is the first left stop, the lower right bell is derived, and if the pushing order is other than the first left stop, the upper bell or the transition start Is derived.

  Further, when winning the simultaneous winning combination, reel control different from that when not winning the simultaneous winning combination can be performed. For example, when a weak watermelon is won, reel control is performed so that a watermelon that falls to the right or an upper watermelon is prioritized over a middle watermelon, but is pulled to the winning line, while a right watermelon is lowered when a strong watermelon is won. Reel control is performed in which the middle-stage watermelon is given priority over both the watermelon and the upper-stage watermelon to be drawn onto the winning line. When a weak cherry or a strong cherry is won, reel control is performed to draw the lower cherries onto the winning line, and when a middle cherry is selected, reel control is performed to pull the middle cherries onto the winning line. . As a result, it is possible to estimate whether it is cherry or watermelon, weak or strong, or middle tier cherry from the combination of symbols when the reels 2L to 2R are stopped, and the expectation for the bonus winning may be different. it can.

[Game processing]
The main control unit 41 performs a game control process to control one game. In the game control process, first, a BET process for setting a bet amount and performing a credit settlement / a bet settlement is performed.

  When the start switch 7 is operated after setting the betting amount, a random number value is extracted from a predetermined random number circuit, and it is determined (internal lottery) whether or not a winning is allowed based on the extracted random number value. The internal lottery process (see FIGS. 10 to 12 and the like) is performed. The random number circuit updates a numerical value within a predetermined numerical value range (0 to 65535) according to a predetermined update rule. The main control unit 41 extracts a numerical value updated by the random number circuit when the start switch 7 is operated as a random value. When a lottery target combination is won in the internal lottery, a winning combination winning flag included in the lottery target combination is set in a predetermined area of the RAM. For example, when BB1 is won, a BB1 winning flag is set, and when a strong cherry is won, a winning flag for the lower cherries and a winning flag for a single piece are set. The winning flags of BB1 and BB2 are carried over until the winning BB is won, while the winning flags corresponding to winning combinations other than BB1 and BB2 are determined when the winning game ends regardless of whether or not a winning has occurred. Will be erased.

  When the internal lottery process ends, a reel rotation process is performed. In the reel rotation process, the stop switches 8L to 8R are activated after the reels 2L to 2R start rotating on the condition that a predetermined time (for example, 4.1 seconds) has passed since the reel rotation start of the previous game. And the rotation of the reel is stopped according to the stop operation (see FIGS. 13 and 14). In the reel rotation process, in order to execute a freeze effect that delays the progress of the game for a predetermined period (delays the activation of the stop operation of each of the stop switches 8L to 8R) when a predetermined freeze condition is satisfied. After executing the freeze effect processing, the stop switches 8L to 8R are validated to shift to the normal game.

  When the reels 2L to 2R are stopped and the reel rotation process is completed, a winning determination process (see FIGS. 5 to 7 and the like) is performed for determining whether or not a winning has occurred based on the symbol combination on the winning line. . Further, the state shown in FIG. 8 is controlled according to the symbol combination on the winning line.

  When the winning determination process ends, a payout process is performed. In the payout process, medals are paid out or credits are added according to the occurrence of a prize, various processes not related to the prize (for example, the process related to the bonus end control by counting the number of medals paid out in the bonus, and the winning without carryover) Flags (deletion of a winning combination such as a small combination / re-playing combination) are performed). Further, when it is determined that either BB1 or BB2 has been won, the winning flag of the winning BB is erased. In the game end process, a process for setting a gaming state in preparation for the next game (see FIG. 8, FIG. 9, etc.) is executed. Thereby, the game control process for one game is completed, and the game control process for the next one game is started.

[Set value]
In the slot machine 1, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by determining the winning probability used in the internal lottery according to the set value. The fact that the winning probability changes according to the set value is referred to as a setting difference, and the fact that the winning probability does not change according to the set value is also referred to as no set difference. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage of the winning probability is the highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, Lower.

  Here, the setting value changing operation will be described with reference to FIG. In order to change the set value, the front door 1b of the slot machine 1 is opened, and the setting key switch 37 provided therein is turned on by a manager such as a store clerk, and the slot machine 1 is turned on. Then, the set value is displayed on the set value display 24 as a display value, and a setting change state in which the set value can be changed by operating the reset / setting switch 38 is set. Here, by operating the reset / setting switch 38, the display value displayed on the set value display 24 is updated one by one. When the start switch 7 is operated after setting the desired set value, the display value is determined as the set value. When the setting key switch 37 is turned off, the determined setting value is stored in the RAM 41c of the main control unit 41, and when the front door 1b is closed, the game shifts to a state in which the game can proceed.

  In this way, by making the transition to the setting change state under the condition of “power ON” + “setting key switch ON” + “front door open detection”, it is illegal for the front door to be in an unopened state. Setting change can be prevented. Once the setting change state is entered, the setting change state is maintained regardless of the open / closed state of the front door until the end condition (setting key switch is turned OFF after setting value is established) is satisfied. Is done. As a result, even if the front door is closed during the setting change state, the setting change state is not terminated, so that it is possible to prevent the trouble of shifting to the setting change state again.

  Among a plurality of types of lottery target roles, there is a role whose winning probability does not change regardless of the set value. For the role, for example, the strong cherries, strong watermelons, weak cherries, and weak watermelons that are AT lottery target roles do not change the winning probability regardless of the set value. Thus, the winning probability does not change regardless of the set value for the lottery target combination for determining the transition to a state in which the degree of advantage for the player is high. The main control unit 41 performs a random number lottery for determining whether or not to shift to a state where the degree of advantage for the player is high, triggered by winning the lottery target role. Such a random number lottery is also called an advantageous period operation lottery. In addition, the winning probability of the advantageous period operation lottery does not change depending on the set value.

  The internal lottery winning probability is changed according to the set value and the winning section operating lottery winning probability is not changed according to the set value, and the internal lottery winning probability is not changed according to the set value and is advantageous according to the set value One that changes the winning probability of the section operation lottery, one that changes the winning probability of the internal lottery according to the setting value, and also changes the winning probability of the advantageous section operation lottery according to the setting value It may be.

[About AT control]
Here, the control of the AT will be described. The main control unit 41 can be controlled to an AT different from an advantageous gaming state such as a bonus or RT2. As already described, AT is a period in which a navigation effect that can specify an operation mode (push order) for stopping a combination of symbols advantageous to the player on the winning line LN is executed. This is an advantageous state. For example, in a game in which replay GR1 (see FIG. 13) is won, a navigation effect is performed by displaying on the liquid crystal display 51 a procedure for winning a promotion replay such as “123!”. However, as the AT, an effect of teaching a design to be pressed or an effect of teaching the timing of pressing may be adopted. That is, the concept of AT is not limited to the notification of the pressing order.

  The lottery regarding the control of AT differs between non-AT and AT. The lottery executed during non-AT is referred to as “AT lottery”, and the lottery executed during AT is referred to as “add-on lottery”. The main control unit 41 executes the AT lottery on the condition that one of the middle tier cherry, strong cherry, strong watermelon, weak cherry, and weak watermelon is won during non-AT. These roles that trigger the AT lottery are called “AT lottery target roles”. In the AT lottery, the number of navigation stocks is drawn from a plurality of types including 0. The navigation stock is a unit of the number of games controlled by the AT. In this embodiment, one navigation stock corresponds to 50 games. Note that the number of navigation stocks = 0 substantially corresponds to the result of non-winning, that is, no AT control.

  The number of navigation stock obtained by the AT lottery is stocked as an AT control right, and AT control is executed in units of navigation stock. For this reason, the number of navigation stocks indicates the number of rights controlled by the AT, and as the number of navigation stocks increases, the number of navigation stocks is controlled by the AT for a longer period. For example, if the number of navigation stocks is 2, after 50 games have been continued for AT, 50 games of AT are executed again based on the next navigation stock.

  The main control unit 41 executes a lottery by adding the AT during the AT. The opportunity for the extra lottery is the same as that for the AT lottery. In other words, the extra lottery is executed on the condition that any of the middle tier cherries, strong cherries, strong watermelons, weak cherries, and weak watermelons that are the AT lottery winning combinations is won. When an extra lottery is won, a predetermined number of games are added as AT games. For example, in a situation where two Navistocks are owned, if 20 games are added by lottery at the stage of the remaining 10 games of the first Navistock, the first 10 games will be the first. When the navigation stock is consumed, the remaining number of games is changed to 30 games. As a result, the AT control based on the first navigation stock is extended, and the AT control based on the second navigation stock is postponed.

  The probability of winning in the AT lottery and the extra lottery depends on the AT lottery target role. As described above, the player wins which lottery target combination is selected from the combination of symbols when the reels 2L to 2R are stopped, such as cherry or watermelon, strong or weak, or middle tier cherry. Can be estimated. Therefore, the player can estimate which AT lottery target combination is won from the combination of symbols when the reels 2L to 2R are stopped, and from the estimation result, the player wins the AT lottery and the extra lottery. Can be predicted. Therefore, it is possible to give the player a different expectation for winning in the AT lottery and the extra lottery from the combination of symbols when the reels 2L to 2R are stopped.

[AT lottery processing]
The AT lottery process will be described in detail using the AT lottery table shown in FIG. The AT lottery process only needs to be executed at a predetermined timing in the progress of one game. For example, the AT lottery process may be executed after the internal lottery is performed in the internal lottery process. The main control unit 41 determines whether or not the navigation stock is held in the AT lottery process. If the main control unit 41 determines that the navigation stock is held, the AT lottery process is terminated because the AT is being performed. If the main control unit 41 determines that the navigation stock is not held, the main control unit 41 is not in the AT, and therefore any of the middle stage cherry, strong cherry, weak cherry, strong watermelon, and weak watermelon that are subject to the AT lottery It is determined whether or not the AT lottery target combination has been won. If it is determined that the AT lottery target combination has not been won, the AT lottery process is terminated.

  If the main control unit 41 determines that the AT lottery target role is won, the main control unit 41 performs AT lottery according to the winning probability shown in the AT lottery table shown in FIG. For example, if you win the middle tier cherry, you decide not to grant navigator stock with a probability of 30%, decide to give one navigator stock with a probability of 35%, and two navigator stock with a probability of 20% And decide to grant one navigation stock with a probability of 15%. Here, deciding not to give the navigation stock means deciding not to control the AT if it is in non-AT.

  If the main control unit 41 decides not to give the navigation stock in the AT lottery after performing the AT lottery, it sends an AT lottery time command indicating that the AT lottery was not won to the sub-control unit 91. Then, the AT lottery process is terminated. When it is determined that the navigation stock is to be given in the AT lottery, the main control unit 41 transmits an AT lottery command indicating that the AT lottery is won and the determined number of navigation stocks to the sub-control unit 91, and also determines the determined navigation The stock number is stored in a predetermined area of the RAM.

  During the AT, the main control unit 41 can control the high probability state where the probability that the number of AT games will be added is high and the low probability state where the probability that the number of AT games will be added is lower than when the probability is high. is there. Therefore, after storing the number of navigation stocks, the main control unit 41 performs a state determination process for determining whether to control the AT in the high-accuracy state or the low-accuracy state, and ends the AT lottery process. .

  As shown in FIG. 15, the ratio determined to give the navigation stock is determined so as to differ depending on the type of the winning lottery winning combination, middle tier cherry> strong cherry = strong watermelon> weak cherry = weak watermelon It is determined to be. In addition, the expected value of the number of navigation stocks to be given is also determined so that middle tier cherry> strong cherry = strong watermelon> weak cherry = weak watermelon.

  Thus, since the probability that the privilege to be controlled by the AT is given varies depending on the type of the lottery target winning by the internal lottery, the interest of the game is improved. In addition, since the expected value of the privilege, the number of navigation stocks corresponding to the period controlled by the AT, also differs depending on the type of the lottery subject winning by the internal lottery, the interest of the game is improved.

  As shown in FIG. 15, a ratio and a ratio determined to give Navistock when winning a strong cherry and when winning a strong watermelon, or when winning a weak cherry and when winning a weak watermelon. The expected value of Navistock is equal. As shown in FIG. 10, the number of determination values is the same for strong cherries and strong watermelons, and is the same for weak cherries and weak watermelons.

  In this way, when winning a strong cherry and winning a strong watermelon, or when winning a weak cherry and winning a weak watermelon, the privilege of controlling to AT is given with the same probability, and Since the expected value of the privilege of the number of navigation stock corresponding to the period controlled by the AT is also equal, the AT lottery can be unified between when winning the strong cherry and when winning the strong watermelon, The processing burden can be reduced.

  In addition, as described above, the AT lottery target combination that determines whether or not to shift to the AT is a combination whose winning probability does not change regardless of the set value. That is, the winning probability does not change regardless of the set value for the middle stage cherry, strong cherry, strong watermelon, weak cherry, and weak watermelon.

  In this way, the probability of winning an AT lottery target role is the same regardless of the set value, so it is not necessary to design by changing the ratio of winning the AT lottery target role for each set value when designing specifications. The work burden at the time can be reduced.

[State determination process]
If the main control unit 41 decides to provide navigation stock in the AT lottery process, the probability that the number of AT games will be added and the probability that the number of AT games will be added during the control to the AT is high. A state determination process is performed to determine which state of the low probability state lower than that in the high probability state is to be controlled. The state determination process shown in FIG. 16 will be described using a state determination table. The main control unit 41 controls the high-accuracy state or the low-accuracy state over a period of digesting one navigation stock. Here, digesting one navigation stock means that the control of the AT for 50 games is completed. The main control unit 41 does not shift to another gaming state during a period in which one navigation stock is consumed. In other words, if the current state is the high-accuracy state, the high-accuracy state is maintained, and if the current state is the low-accuracy state, the low-accuracy state is maintained, and the state between the high-accuracy state and the low-accuracy state is maintained. There is no migration. Therefore, even if the number of AT games is increased during the AT based on Navistock, until all AT games of Navistock provided including the added number of AT games are completed, The current state (low or high probability state) is maintained. That is, during the AT period, there is no transition from one to the other between the high-accuracy state and the low-accuracy state.

  In FIG. 16, “high accuracy” indicates a high accuracy state, and “low accuracy” indicates a low accuracy state. The right arrow indicates that one navigation stock is digested and the next navigation stock is digested. For example, “high accuracy”, “right arrow”, and “low accuracy” It is shown that the high-accuracy state is controlled while digesting Navistock, and the low-accuracy state is controlled while digesting the next Navistock.

  In the state determination process, the main control unit 41 determines a state during the control to the AT using a state determination table that varies depending on the number of assigned navigation stocks. When it is determined to give one navigation stock by AT lottery, the state while being controlled by the AT is determined using the state determination table shown in FIG. When it is determined that two navigation stocks are to be given by the AT lottery, the state while being controlled by the AT is determined using the state determination table shown in FIG. When it is determined that three navigation stocks are to be given by the AT lottery, the state while being controlled by the AT is determined using the state determination table shown in FIG.

  The main control unit 41 determines the state during the AT control using the state determination table shown in FIG. 16, and then determines information regarding which state is controlled during digestion of the navigation stock determined in the state determination process. The data is stored in a predetermined area of the RAM, and the state determination process is terminated.

[AT control processing]
The main control unit 41 performs AT control processing for controlling the AT. The AT control process only needs to be executed at a predetermined timing in the progress of one game. For example, the AT control process may be executed after the internal lottery is performed in the internal lottery process. In the present embodiment, the control is performed by the AT when the control is performed by any one of RT0 to RT3. That is, the AT is not controlled when the bonus is won and during the bonus.

  In the AT control process, the main control unit 41 determines which gaming state is controlled, and if it is determined that the bonus is won during RT4 or during the bonus, the AT control process Exit. When it is determined that the main control unit 41 is controlled by any one of RT0 to RT4, the main control unit 41 determines whether or not the AT remaining game number is not zero. Whether or not the number of remaining AT games is not 0 is determined based on the number of AT games stored in a predetermined area of the RAM. The main control unit 41 determines whether or not navigation stock remains when the number of remaining AT games is 0, and ends the AT control process when determining that no navigation stock remains. Whether or not navigation stock remains is determined based on the number of navigation stocks stored in a predetermined area of the RAM. When the navigation stock remains, the main control unit 41 stores 50 games in a predetermined area of the RAM as the number of AT games in order to digest the remaining navigation stock and continue the AT. The main control unit 41 subtracts 1 from the number of AT games each time one game is consumed during AT. In addition, during the AT, when adding the number of AT games in the extra lottery process, the main control unit 41 adds the number of AT games to be added to the remaining number of AT games of Navistock that is currently being digested. Is added.

  When the main control unit 41 determines that the number of remaining AT games is not 0, the main control unit 41 determines that the AT is in progress, the number of remaining AT games, and whether the current state is a highly accurate state or a low probability state. The AT command including the information to be transmitted is transmitted to the sub-control unit 91. When the main control unit 41 determines that the number of AT remaining games is 0 and the navigation stock remains, the main control unit 41 continues the new AT, the number of remaining AT games = 50, and the current state is A command during AT including information indicating whether the state is highly accurate or not reliable is transmitted to the sub-control unit 91.

[Additional lottery processing]
The extra lottery process will be described using the extra lottery table shown in FIG. In the extra lottery process, the main control unit 41 determines whether or not one of the lottery object combinations among the weak watermelon, the strong watermelon, the weak cherry, the strong cherry, and the middle cherry is won. When the main control unit 41 determines that none of the lottery object combinations has been won, the addition lottery process is terminated. If the main control unit 41 determines that any of the lottery targets is won, the main control unit 41 performs the lottery with a different probability depending on whether the winning state is the high probability state or the low probability state. Whether the state is highly accurate or not is determined based on information stored in a predetermined area of the RAM. Further, the main control unit 41 performs an extra lottery based on which one of the lottery targets selected from among the weak watermelon, the strong watermelon, the weak cherry, the strong cherry, and the middle cherry. For example, if the player is in a highly probable state and wins the middle stage cherry, the winning lottery is won with a probability of 80%.

  When the main control unit 41 wins the extra lottery, the main control unit 41 determines the number of AT games to be added. The main control unit 41 adds the determined number of AT games to the number of AT games stored in a predetermined area of the RAM. As a result, the remaining number of games of Navistock that is currently being digested is increased. Further, the main control unit 41 transmits an addition lottery command that can specify whether or not the addition lottery is won and the number of AT games to be added to the sub-control unit 91, and finishes the addition lottery process.

  As shown in FIG. 17, the winning winning probability is determined to be different depending on which state is controlled to be a high probability state or a low probability state and the type of the winning lottery winning combination. . Specifically, the high probability state is more advantageous to the player than the low probability state because the winning lottery is won with a high probability when the high probability state is controlled. Further, the winning winning probability is determined such that middle cherry> strong cherry = strong watermelon> weak cherry = weak watermelon. Thus, since the probability that the privilege of adding the period to be controlled by the AT is different depending on the type of the lottery role won by the internal lottery, the interest of the game is improved.

  Further, the expected value of the number of AT games to be added is determined such that middle stage cherry> strong cherry = strong watermelon> weak cherry = weak watermelon. In this way, the expected value of the privilege, which is the number of AT games corresponding to the period controlled by the AT, differs depending on the type of the lottery target winning by the internal lottery, so that the interest of the game is improved.

  As shown in FIG. 17, when winning a strong cherry and winning a strong watermelon, or when winning a weak cherry and winning a weak watermelon, the probability of winning an extra lottery and the AT game to be added The expected value of the number is equal. As shown in FIG. 10, the number of determination values is the same for strong cherries and strong watermelons, and is the same for weak cherries and weak watermelons.

  In this way, when winning a strong cherry and when winning a strong watermelon, or when winning a weak cherry and winning a weak watermelon, to win the lottery with the same probability, we won the strong cherry Depending on when and when a strong watermelon is won, the extra lottery can be unified, and the processing load on the main control unit 41 can be reduced.

  Further, as described above, the lottery target combination that determines whether or not to shift to AT is a combination whose winning probability does not change regardless of the set value. Here, the lottery target combination that determines whether or not to shift to the AT is an AT lottery target combination. Therefore, the winning probability does not change for the middle tier cherry, strong cherry, strong watermelon, weak cherry, and weak watermelon regardless of the set value.

  In this way, the probability of winning an AT lottery target role is the same regardless of the set value, so it is not necessary to design by changing the ratio of winning the AT lottery target role for each set value when designing specifications. The work burden at the time can be reduced.

[About various commands]
The main control unit 41 transmits to the sub-control unit 91 a command that can specify the progress of the game and the processing result according to the execution of the processing exemplified above. The sub control unit 91 performs various processes based on commands from the main control unit 41.

  In the present embodiment, the main control unit 41 makes an internal winning command, a push order command, a stop switch or start switch operation command, a gaming state command, an AT lottery command, an AT command, an extra lottery to the sub-control unit 91. Send multiple types of commands including hour commands.

  The internal winning command is a command that can specify the group to which the lottery object combination that has been won according to the result of the internal lottery belongs. The internal winning command is transmitted when the start switch 7 is operated and the game is started. By receiving the internal winning command, the sub-control unit 91 can specify the operation of the start switch 7 and the group to which the winning lottery combination belongs.

  The push order command is a command that can specify an operation procedure (also referred to as a correct answer procedure) for stopping a symbol combination that is advantageous to the player in accordance with the lottery object winning combination in the internal lottery. The push order command is transmitted when the start switch 7 is operated and the game is started. During AT, a push order command that can specify the correct procedure is sent, whereas during non-AT, a push order command that can specify the correct procedure is not sent, and the correct procedure cannot be specified. A push order command (for example, a push order command capable of specifying a common procedure regardless of the winning combination) is transmitted, or no push order command is transmitted. For this reason, the sub-control unit 91 can identify the correct procedure by receiving the push order command during AT, but cannot identify the correct procedure during non-AT.

  The operation command for the stop switch or start switch is a command indicating that the stop switch or start switch has been operated, and is transmitted at each operation. The gaming state command is transmitted when the gaming state transitions. Specifically, it is transmitted when RT shifts or is controlled by a bonus.

  The AT lottery command is transmitted when the AT lottery is performed, whether or not the AT lottery is won, how many navigation stocks are assigned, and the high and low probability states during the AT. It is a command that can specify which state is controlled.

  The AT command is transmitted when the game starts, whether or not the game is an AT game, the number of remaining AT games, the number of remaining navigation stocks, and the current state of high or low probability It is a command that can specify whether or not. The extra lottery command is a command that is transmitted when the extra lottery is performed, and can specify whether or not the extra lottery is won and the number of AT games to be added.

[Directing during AT]
The effects performed by the main control unit 41 and the sub control unit 91 during the AT will be described. During the AT, the main control unit 41 displays information that can identify the stop order of the reels on the game auxiliary display 12. The sub-control unit 91 displays a navigation effect image (not shown) for instructing the stop order of reels on the liquid crystal display 51, and an image that can specify the number of remaining AT games ("35G" in FIG. 18A). ) And an image suggesting which of the high-accuracy state and the low-accuracy state is displayed. For example, when the replay GR 2 is won, “2” is displayed on the game auxiliary display 12 as information that can specify “left, right, middle”, which is the push order for winning the promoted replay, and the liquid crystal display In 51, an image that can specify that the stop switch 8 is operated in the order of “left, right, and middle” is displayed. In addition, the image that suggests the high-accuracy state is a background image (see FIG. 18A) indicating that it is daytime, and the image that suggests the low-accuracy state is a background image that indicates that it is midnight. (See FIG. 18D).

[Direction at the time of extra lottery]
The effect at the time of lottery with addition will be described with reference to FIG. FIG. 18 is a diagram illustrating an example of an effect at the time of extra lottery. As shown in FIG. 18, during AT, the number of remaining AT games is displayed in the upper left display area of the liquid crystal display 51 (displayed as “35G” in FIG. 18A). Here, the number of remaining AT games is information indicating how many remaining games one digest stock is consumed. The sub-control unit 91 may use the liquid crystal display 51 to produce an effect that suggests whether or not to continuously control the AT every time one navigation stock is digested.

  FIG. 18 is an effect drawing for explaining an effect using the liquid crystal display 51 that is executed during one game in the AT, and is an effect drawing when the state is controlled to be highly accurate. FIG. 18A is an effect drawing in a state where the BET processing is completed and an operation to the start switch 7 can be accepted. In FIG. 18A, a first background indicating the daytime is displayed on the display screen of the liquid crystal display 51. The first background is an image that is easily selected when the low-accuracy state is controlled (see FIG. 19), and is an image that suggests that the low-accuracy state is controlled.

  FIG. 18B is an effect screen that is displayed when an extra lottery is performed during AT. This effect screen is displayed after all reels have stopped in the game in which the lottery is performed. When the extra lottery is performed, a button effect may be executed as an extra notification effect for notifying whether or not the extra lottery has been won. FIG. 18B shows such a button effect screen.

  The button effect displays a button image, prompts an operation to the effect switch 56 (see FIG. 1), and displays a predetermined image indicating whether or not the winning lottery is won according to the operation to the effect switch 56. It is a production to make. After the image prompting the operation to the effect switch 56 shown in FIG. 18 (B) is displayed, if the operation to the effect switch 56 is performed, when the player is out of the extra lottery, the extra lottery is not won. As an image indicating this, a character image “sorry” as shown in FIG. 18C is displayed. Note that when winning the extra lottery, a character image “I did it” is displayed. When the next game is started after the image indicating that the extra lottery is not won is displayed, the screen is switched to the second background indicating the midnight different from the first background as shown in FIG. There are cases where the background does not switch as shown in FIG. The second background is an image that is more easily selected in the high-accuracy state than in the low-accuracy state (see FIG. 19), and is an image that suggests that the high-accuracy state is controlled.

  However, regardless of whether the background is switched or the background is not switched, the current state (high-accuracy state or low-accuracy state) is maintained while the AT control based on one navigation stock continues. Is maintained. Therefore, for example, the AT control based on one navigation stock is continued in the high-accuracy state, and the background image at that time is the first background corresponding to the low-accuracy state (see FIG. 18A). Even after the disappointing screen shown in FIG. 18C is displayed, even if the background is switched to the second background suggesting a high-accuracy state (see FIG. 18D), the actual state remains the high-accuracy state. Will be. Therefore, even if it is a case where it is out of the lottery in the highly accurate state, by switching the background to the second background, it is possible to prevent the player from being distracted by the fact that it is out of the top lottery. It can be prevented from decreasing. In addition, since there is actually no state transition, the processing load on the slot machine can be reduced compared to the case where control is performed to actually shift the state at that time.

[Background determination processing]
The sub-control unit 91 executes background determination processing for determining the background to be displayed on the liquid crystal display 51 during AT. The sub-control unit 91 determines the background to be displayed in the next game by the background determination process, and displays the background determined by the background determination process on the liquid crystal display 51 when the next game starts. When the game starts, it means the timing when the start switch 7 is operated. That is, the background is displayed at the timing when the start switch 7 is operated. However, instead of this, if you win the re-gamer, the background is displayed when you operate the start switch, and if you do not win the re-gamer, the background when 1 or more bets are set May be displayed.

  The sub-control unit 91 displays any background when the control to the AT is started by the background determination process and when the navigation stock is digested and the control to the AT is performed based on the next navigation stock from the next game. It is determined whether or not to switch the background to a different background when an extra lottery is performed. The sub-control unit 91 determines whether or not the AT is being performed in the background determination process. Whether or not AT is in progress is determined based on whether or not an AT command is received. If the sub-control unit 91 determines that the AT is not in progress, the sub-control unit 91 determines whether or not the AT lottery is won based on the AT lottery command. The sub-control unit 91 ends the background determination process when the AT lottery command is not received and when it is determined that the AT lottery is not won.

  When it is determined that the AT lottery is won, the sub-control unit 91 determines the background to be displayed on the liquid crystal display 51 when starting AT based on the background selection table shown in FIG. Based on the command at the time of AT lottery, the sub-control unit 91 determines which state is to be controlled between the high-accuracy state and the low-accuracy state at the start of AT, and determines that it is controlled to the low-accuracy state. When the background is selected using the background selection table shown in FIG. 19A, and the background is selected using the background selection table shown in FIG. To do. For example, when it is determined that the control is in the low probability state, the first background is selected with a probability of 90% and the second background is selected with a probability of 10%. After determining the background at the start of the AT, the sub-control unit 91 stores information that can specify which background is displayed in a predetermined area of the RAM, and ends the background determination process.

  When the sub-control unit 91 determines that the AT is in progress, one navigation stock is digested when the game ends, and whether or not the next game is controlled by the AT based on a new navigation stock is determined. judge. Specifically, the sub-control unit 91 determines whether or not the remaining number of AT games and the remaining number of navigation stocks are both 0. If it is determined that both are 0, the sub-control unit 91 starts from the next game. It is determined that the AT is not controlled, it is determined that neither the first background nor the second background is displayed in the next game, and the background determination process is terminated. When the remaining AT game is 0 and the number of remaining navigation stocks is 1 or more, the sub-control unit 91 digests one navigation stock by completing the game, and based on the new navigation stock from the next game. The background to be displayed on the liquid crystal display 51 when it is controlled by the AT based on the new navigation stock is determined based on the background selection table shown in FIG. When the sub-control unit 91 determines that the low-accuracy state is controlled based on the new navigation stock, the sub-control unit 91 determines the background using the background selection table shown in FIG. When it is determined that the state is controlled to the highly accurate state, the background is determined using the background selection table shown in FIG.

  When the sub-control unit 91 determines that the next game is also controlled by the AT and the navigation stock is not digested even when the game ends, the sub-control unit 91 performs a background switching process for switching the background and ends the background determination process. To do.

[Background switching]
If the sub-control unit 91 determines that the next game is also controlled by the AT and that the navigation stock is not consumed even when the game ends, the sub-control unit 91 performs a background switching process for switching the background. Background switching can occur when the main control unit 41 performs an extra lottery process. The sub-control unit 91 determines whether or not the extra lottery has been performed based on whether or not the extra lottery command has been received, and determines that the background is not switched when it is determined that the extra lottery has not been performed, It is determined to continue displaying the background displayed in the game.

  When it is determined that the extra lottery has been performed, the sub-control unit 91 determines whether to switch the background based on the background switching table shown in FIG. The sub-control unit 91 determines which background switching table of FIGS. 20A to 20D to use based on the AT command and the currently displayed background.

  When the sub-control unit 91 is controlled in the low-accuracy state and the first background is displayed, the sub-control unit 91 determines whether to switch the background using the background switching table of FIG. In this case, if it is determined that the extra lottery is won based on the extra lottery command, it is determined that the first background is switched to the second background with a probability of 40%, and the background is determined with a probability of 60%. Decide not to switch.

  When the sub-control unit 91 is controlled in the low-accuracy state and the second background is displayed, the sub-control unit 91 determines whether to switch the background using the background switching table of FIG. When the sub-control unit 91 is controlled to be in a highly accurate state and the first background is displayed, the sub-control unit 91 determines whether to switch the background using the background switching table of FIG. When the sub-control unit 91 is controlled to be in a highly accurate state and the second background is displayed, the sub-control unit 91 determines whether to switch the background using the background switching table of FIG. When the high-accuracy state is controlled and the second background is displayed, the background is not switched regardless of whether the winning lottery is won or not.

  As shown in FIG. 20 (C), when the first background suggesting the low-accuracy state is displayed during the high-accuracy state, when it is decided to win the extra win and give the AT game, It is possible to switch to the second background. For this reason, the number of AT games may be given when the first background suggesting a low probability state is displayed, and the first background may be switched to the second background. In such a case, the player is delighted that the AT game has been granted, and has expectations for games after the game in which the AT game has been granted by switching to the second background, The fun of gaming is improved.

  In addition, as shown in FIG. 20C, when the first background suggesting the low-accuracy state is displayed during the high-accuracy state, the second background can be obtained even when the winning combination is not won. It is possible to switch to. Therefore, the first background may be switched to the second background even when the number of AT games is not given when the first background suggesting the low probability state is displayed. In such a case, although the player feels regrettable that the AT game has not been granted, the player is also expected to play a game after the game in which the AT game has not been granted due to switching to the second background. In this way, the fun of gaming is improved.

[effect]
(1) In the slot machine of the present embodiment, the transition from one to the other between the high-accuracy state and the low-accuracy state does not occur during a predetermined period until one navigation stock is consumed. In other words, when an AT lottery target is won during AT, an extra lottery is performed, and even if the extra lottery is won or not, one from the high-probability state and the low-probability state is changed from one to the other. No transition occurs. Therefore, when the extra lottery is performed, it is possible to reduce the processing load related to the determination related to the state transition as compared with the case where the determination regarding the state transition is performed. However, although the state is not shifted, the background can be switched from the first background to the second background, so that the game after the background is switched can be expected and the interest of the game can be improved. For example, when it is decided not to give a privilege, if the background is switched from the first background to the second background, the background will be switched to the second background, although it is disappointing that the privilege is not given. In this way, it is possible to raise expectations for the subsequent lottery, so the interest of the game is improved.

  (2) In the slot machine of the present embodiment, the main control unit 41 determines which of the high-accuracy state and the low-accuracy state is controlled, and which background the sub-control unit 91 displays. decide. Therefore, compared with the case where the control during AT and the presentation during AT are determined by one control unit, the burden on each control unit can be suppressed, and the necessary storage capacity can be distributed in each control unit. .

[Main variations]
The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

[About background switching]
In the present embodiment, when the first background is displayed in the low-accuracy state, an extra lottery is performed, and when it is determined not to add, the background is not switched (see FIG. 20A). However, even if it is determined not to be added, it may be determined whether or not the background is switched and the background is switched at a certain rate. In this way, since it can be switched to the second background even in the low probability state, it can appear as if the player has shifted to the high probability state, and the player can play the game after switching to the second background. Can be expected to improve the fun of gaming.

  Further, in the present embodiment, when the second background is displayed in the low-accuracy state, an extra lottery is performed, and when it is determined not to add, the background is switched (see FIG. 20B). However, even if it is determined that the background is not added, it may be determined whether or not the background is switched, and it is determined that the background is not switched at a certain rate. In this way, in the low probability state, the second background is continuously displayed even if the winning lottery is not won while the second background is displayed. Expectations for the subsequent games can be maintained.

  In the present embodiment, the background is not switched during the display of the second background in the high-accuracy state regardless of whether or not the extra lottery is won (see FIG. 20D). However, when the extra lottery is not won, it may be determined to switch the background at a certain rate. In addition, when the winning lottery is won, it may be determined to switch the background at a certain rate.

[Direction that suggests the state]
In the present embodiment, the background image indicating the daytime and the background image indicating the nighttime are given as examples of the effects suggesting the state, but the present invention is not limited thereto. For example, the display mode of the character may be an effect that suggests the state. Specifically, when controlled to the low-accuracy state, the character is likely to be displayed in the first mode in white clothes, and when controlled to the high-accuracy state, the character is dressed in red. The state may be suggested depending on the character display mode. Moreover, you may suggest a state by changing the color of the lamp | ramp and LED which were attached to the front door 1b. Further, the state may be suggested depending on the type of music output from the speaker included in the slot machine 1.

[How to determine the status]
In this embodiment, the state during the digestion of all the Navistock given at the time of the AT lottery is determined at the time of the AT lottery, but the control is performed while the next Navistock is digested every time the Navistock is digested. The state to be performed may be determined. In addition, until one Navistock is digested, it is assumed that the state is maintained in a state of low accuracy or high accuracy. That is, the slot machine according to the present embodiment is controlled to a low-accuracy state or a high-accuracy state over a navigation stock period that is an example of a predetermined period. Here, it is also conceivable to set a predetermined period other than the navigation stock period. For example, when the AT control is managed using only the AT game without using the navigation stock, the period of the number of AT games given at one time may be set as the predetermined period. Specifically, when the number of AT games to be granted is determined by lottery from 0 games, 50 games, 100 games, and 150 games without using navigation stock at the time of AT lottery, It may be controlled to a low-accuracy state or a high-accuracy state over 100 games so that no state transition occurs. In this case, when 50 games are awarded by winning the extra lottery during 100 games, the state transition does not occur during the 100 games, and the state transition does not occur during the added 50 games. It may be prevented from occurring. In addition, the state transition may not always occur during 50 games. Specifically, when the number of AT games is 180 games, the high probability state during the first 50 games, the low probability state during the next 50 games, and the high probability state during the last 30 games, etc. You may control.

  In addition, the state may be determined so that the ratio for controlling to the high-accuracy state and the ratio for controlling to the low-accuracy state differ depending on which AT lottery target combination is won. For example, when the middle stage cherry is won, the period for controlling to the high probability state may be set to be long, and when the weak cherry is won, the period for controlling to the low probability state may be set to be long. Thereby, the period of time that is controlled to a highly accurate state advantageous to the player varies depending on which AT lottery target combination is won, so that the interest of the game is improved.

[About the first state and the second state]
In the present embodiment, the low-accuracy state is described as an example of the first state, and the high-accuracy state is described as an example of the second state that is more advantageous than the first state. The low probability state and the high probability state differ from each other in the extra lottery probability. However, the first state and the second state may be in a state where the degree of advantage for the player is different. For example, the state controlled by CZ having a high AT lottery probability may be set as the second state, and the non-AT state not controlled by CZ may be set as the first state. In addition, a state that is advantageous in that the winning probability of a small role is higher than that in the first state may be set as the second state.

  In addition, for example, a regular bonus (RB) or replay time (RT) in which a winning probability of a predetermined winning combination is high, a concentrated state of small roles, and a range where at least one reel can be drawn are usually advantageous. Operation procedure for winning the winning small role instead of changing the challenge time (CT), the winning probability of winning winnings, etc., which becomes narrower and allows the occurrence of all small winnings in each game May be a pseudo bonus or the like for informing the user over a predetermined period (for example, until 50 games are consumed). In addition, the probability of being controlled to these advantageous states may be a high probability, the probability of being controlled to the freeze state is high, and the number of games such as the number of AT games is high. You may set the advantageous state of a different aspect from the said embodiment, such as the state added and the state where it is easy to increase the number of additional games of AT. In addition, it is indirectly advantageous for the player, such as the condition for obtaining a privilege on the communication line network and the probability of establishing a condition for executing a premium effect (freeze effect, premium effect, etc.). It may be a state where a special privilege or an interest of the game is improved. Further, the allowance determining means for determining whether or not to allow the transition to an advantageous state is not limited to the internal lottery process, and may be a means for determining regardless of the winning combination.

  Further, the advantageous state is given when, for example, in the privilege grant lottery that determines whether or not a privilege is granted, the “probability that a privilege is granted” and “the privilege is given” are determined. At least one of “the value of the privilege (or the expected value of the privilege)” may be higher than the normal state (a state different from the advantageous state). In addition, the advantageous state may be one in which the number of execution opportunities for the privilege grant lottery is larger than that in the normal state. In addition, the advantageous state may be a state where the number of digestion-required games that need to be digested in order to give a privilege is less than a normal state.

  For example, in the case where the privilege is the number of AT games, the advantageous state means that “AT winning probability in AT lottery” and “AT awarded when winning AT in AT lottery” than in the normal state At least one of “the value of the number of games” may be higher than the normal state. Further, the advantageous state may be that the number of AT lottery triggers is larger than that in the normal state. For example, when the AT lottery execution opportunity in the normal state is the first role winning and the second role winning, the AT lottery execution opportunity in the advantageous state is the first role winning and the second role winning. In addition to the above, it is possible to win the third role.

[About benefits]
In the above-described example, the number of AT games is given as an example as a privilege, but it is not limited to this. For example, values that directly affect the payout rate of medals and pachinko balls, such as BB winning and AT winning, values that improve the degree of advantage for players, and values that do not directly affect the payout rate of medals It may be. Specifically, when an AT lottery has a high probability state in which AT is won with a higher probability than usual, execution of a probability suggestion effect to suggest whether or not the current state is a high probability state , Execution of a premier effect together with sound on the liquid crystal display 51 (special character appearance, execution of special bonus effect in the next generated bonus, etc.), execution of a set value suggestion effect to suggest a set value, Collecting a certain number of liquid crystal displays a two-dimensional code that gives points that can be exchanged for services determined at the amusement store where the slot machine 1 is installed, and that can download bonus videos and bonus information on a predetermined website A display or the like may be displayed in the device 51.

  Moreover, although the number of AT games is illustrated as an example of the privilege, the privilege related to the AT is not limited to this. Good. In addition, when the number of times that the navigation effect can be executed is determined and the AT is controlled until the navigation effect is executed for the determined number of times that the navigation effect can be executed, Good. Further, for example, when the upper limit grant amount is determined and the AT is controlled until the assigned game value (medal payout number) reaches the determined upper limit grant amount, the upper limit grant amount may be a privilege. In addition, when the AT is controlled from when the predetermined AT start condition is satisfied until the predetermined AT end condition is satisfied, and if the AT is continued when the AT end condition is satisfied, the continuous lottery is performed. The continuation probability determined to continue in the lottery may be used as a privilege.

[Regarding the modification example of the extra notification effect]
In the present embodiment, an example has been described in which the background is switched after informing whether or not the extra lottery has been won (FIGS. 18C and 18D). However, the background may be switched at a timing when it is notified whether or not the extra lottery is won. In addition, (a) Notifying at the same timing (this is referred to as timing TA) when the winning lottery is won and when not winning, the background is switched at that timing TA. Also good. Furthermore, (i) when the extra lottery is not won, the fact may not be notified, and in that case, the background may be switched at the timing TA. Even without notifying that the extra lottery was not won, the player can understand that the extra lottery was not won by not being notified at the timing TA that the extra lottery was won. Hereinafter, with reference to FIG. 21, a modified example of the additional notification effect as described in (A) above will be described in detail.

  FIG. 21 is an effect drawing from when the extra lottery is performed during the AT to when the lottery result of the extra lottery is notified, and is an effect drawing when the high-precision state is controlled. In FIG. 21A, the first background indicating the daytime is displayed on the display screen of the liquid crystal display 51. When the start switch 7 is operated and the middle cherries are won, an extra lottery is performed. After that, when all the reels 2L to 2R are stopped and the middle cherry is won in the game, a character image “chance!” Is displayed on the liquid crystal display 51 as shown in FIG. This suggests that a lottery was performed on the player. After that, as an effect of recognizing whether or not the winning lottery is won over three games, a character image “Zawa ..., Zawa ...” is added to the first background as shown in FIG. The rendered effect image is displayed on the display screen of the liquid crystal display 51. When the operation to all the stop switches 8L, 8C, and 8R is completed in the third game, if the winning lottery is won, as shown in FIG. 21E, the fact that the winning lottery has been won is notified. Therefore, a character image “+10 game GET !!” is displayed, and the number of AT games displayed in the upper left display area of the liquid crystal display 51 is updated to “41G”. Let TA be the timing at which the character image is displayed. On the other hand, when the extra lottery has not been won, the background image is switched to the second background at the previous timing TA without being notified as shown in FIG. The player is not actively informed that he has not won the extra lottery, but the player is not informed of the extra lottery at the timing TA (the timing to be informed if he has won). I understand that I didn't win.

  As you can see, even if you didn't win the extra lottery, it was unfortunate that you didn't win the extra lottery by switching to the second background, which suggests that it is controlled in a highly accurate state. Although it thinks, it has expectation also about the game after switching to the 2nd background by having switched to the 2nd background, and the interest of a game improves. In addition, if the background changes after it is informed that the player has not won the extra lottery, the player will be expected to go through a period in which the player can only feel unfortunately. By making the timing TA at which the player can understand whether or not the lottery has been won and the timing at which the background is switched to be the same, it is possible to eliminate a period in which the player can only feel unfortunately. In addition, as described above, when the background is switched, there is actually no state transition, so the processing of the slot machine is compared to the case where control is performed to actually transition the state at that time. The burden can be reduced.

  It should be noted that it is not necessary to provide a period during which an effect such as “Zawazawa” is used to determine whether or not the extra lottery has been won. Moreover, you may perform what is called a battle effect that an enemy character and a friend character fight as an effect which makes a determination whether or not the extra lottery is won. When the winning lottery is won, the character image “WIN” is displayed together with the effect that the teammate character wins in the battle effect, but the background may not be changed. In addition, when the winning lottery is not won, an effect that the teammate character loses in the battle effect may be performed, and a character image “LOSE” may be displayed to switch the background.

[Modification of slot machine]
In the above embodiment, the slot machine that pays out game media to the player's hand according to the occurrence of a win has been described. However, the game medium is enclosed, and the game media is paid out to the player's hand when a win occurs. An enclosing slot machine that adds game points (scores) without any change may be adopted. The base and the drum can be distributed, and the chassis is common and only the base or the base and the drum is called a gaming machine. In addition, the slot machine has a game area in which a game ball can be launched and a game can be played, and a betting amount can be set according to the game ball passing through a predetermined area provided in the game area. May be.

  Further, in the above-described embodiment, a plurality of reels capable of variably displaying a plurality of types of symbols each identifiable are provided, and after the reels are variably displayed, the display results are derived by stopping the reel variability display, A slot machine that can generate a winning according to a combination of display results of a plurality of reels has been described. In other words, a plurality of variable display units capable of variably displaying a plurality of types of identification information each identifiable are provided, and after the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. A slot machine that can generate a winning according to a combination of display results of a plurality of variable display units has been described. However, a variable display unit capable of variably displaying a plurality of types of identification information each identifiable is provided. After the variable display unit is variably displayed, the display result is derived by stopping the variable display of the variable display unit. As long as the slot machine can generate a prize according to the display result, the slot machine is not limited to one having three reels, but one having only one reel or a slot machine having a plurality of reels other than three. Also good.

[About production and notification]
In the above-described example, an example in which the liquid crystal display 51 is used to produce effects and notifications is given. For example, speakers 53 and 54, a back lamp (reel LED 55 in the above embodiment) arranged on the back side (inside) of the reel. ), Transmissive liquid crystal display arranged on the front side of the reel (liquid crystal display configured so that the reel can be seen), lamps and LEDs mounted on the front door 1b, etc., vibration of the stop switch, around the stop switch The effect may be executed by means different from the above-described embodiment, such as air blowing from the air or a change in the temperature of the stop switch.

[About AT]
In the example of the slot machine, the example in which the main control unit 41 executes the control related to the AT has been described, but the AT related control executed by the main control unit 41 includes execution of an AT lottery. The AT lottery may include winning or non-winning AT lottery, determining whether or not to stock the number of AT games, determining the number of AT games, adding the number of AT games, and the like. In addition, as a control related to the AT, a high probability state control of the AT lottery is exemplified. For the control of the high probability state of AT lottery, the control that increases the probability of winning the AT lottery, the control that shortens the period until the AT is controlled according to the result of the internal lottery, the winning probability of the extra lottery Includes controls that favor numbers. Further, as control related to AT, it is possible to control to AT when a prescribed number of games have been consumed. The case where the prescribed number of games have been consumed includes the case where the ceiling game number is reached and the case where the number of games determined by lottery is reached. Further, as control related to AT, control for setting a precursor period can be cited. The control for setting the precursor period includes, for example, control for producing effects of 0 to 32 games in the precursor period before the start of AT. Moreover, control which gives a penalty is mentioned as control which concerns on AT. The control for giving a penalty includes determination of penalty contents and determination or setting of a penalty period. In addition, as control related to AT, the main control unit 41 performs lighting control of a lamp and an LED indicating that AT is in progress.

  In addition, as the control related to AT, the main control unit 41 performs lighting control of lamps and LEDs for executing a navigation effect. Further, the sub control unit 91 may execute the navigation effect in conjunction with the main control unit 41 executing the navigation effect. Further, when the main control unit 41 improves the lottery probability, for example, when controlling to the high probability state of the AT lottery, for example, this is notified by lighting control of a lamp or LED (for example, the game auxiliary display 12). You may do it. More specifically, the main control unit 41 may notify that it is controlled to the high probability state of the AT lottery by executing the navigation effect a predetermined number of times by the game auxiliary display 12. Alternatively, the main control unit 41 may notify the sub-control unit 91 that the navigation effect is executed a predetermined number of times to control to the high probability state of the AT lottery.

  When the main control unit 41 executes the control related to the AT, it is preferable that the process of the main control unit 41 is executed by the control unit subordinate to the main control unit 41 and subordinate to the main control unit 41. . For example, the control unit provided on the board other than the game control board executes the reel stop control, and the main control unit 41 transfers the operation signal of the stop switch to the control unit. In this way, by causing the lower-level control unit to perform the control of the main control unit 41, it is possible to prevent the capacity of the ROM 41b and the RAM 41c from being insufficient and the processing capacity of the main CPU 41a from being insufficient when performing the control related to the AT.

  In the above-described embodiment, the main control unit 41 executes the control related to the AT. However, the sub-control unit 91 may execute the control. The sub-control unit 91 performs, for example, an AT lottery process or an extra lottery process based on an internal winning command from the main control unit 41, and executes a process for controlling the AT or a navigation effect according to the result. Processing or the like may be performed.

[Setting change status and setting check status]
Regarding the setting confirmation state, the setting confirmation state may be shifted on condition that “setting key switch ON” + “front door opening detection”. Thereby, unauthorized setting confirmation in the state where the front door is not opened can be prevented. Once the setting confirmation state has been entered, the setting confirmation state is maintained regardless of whether the front door is open or closed until an end condition (setting key switch is turned OFF) to end the setting confirmation state is satisfied. Also good. Thereby, even if the front door is closed during the setting confirmation state, the setting confirmation state is not terminated, and therefore it is possible to prevent the trouble of shifting to the setting confirmation state again.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
