Description

  The present invention relates to a slot machine that generates a specific state in which the internal winning probability of a replay combination is different from a normal state.

  Conventionally, for example, there is a slot machine in which an internal winning combination including a bonus combination is determined by lottery and the internal winning combination is set to be able to win. In this slot machine, when a bonus combination is determined as an internal winning combination, the bonus combination can be won by stopping with a symbol corresponding to the bonus combination. On the other hand, if the bonus combination is not determined as the internal winning combination, it cannot be stopped even if the symbol corresponding to the bonus combination is aimed. Therefore, it is difficult for the player to immediately know whether or not the bonus combination is won internally, and it is difficult to maintain the expectation for the bonus combination over a plurality of games.

  Therefore, by setting a replay role that wins in preference to the bonus role over a predetermined period after the internal winning of the bonus role, with high probability, it is set so that winning of the bonus role is unlikely to occur during the predetermined period. A slot machine has been proposed (see, for example, Patent Document 1). In this slot machine, the expectation for the internal winning of the bonus combination can be maintained over the predetermined period. Furthermore, by setting multiple types of bonus combinations, it is difficult to determine the type of bonus combination that was won internally, and the percentage of internal winnings of multiple types of replay combinations was changed according to the type of bonus combination. There are also suggestions. This slot machine intends to give the player a pleasure of predicting the type of bonus combination that is won internally according to the winning frequency of each replay combination.

  However, the conventional slot machine described above has the following problems. In other words, in slot machines where the probability of winning a replay role is increased and the bonus role is difficult to win, or in slot machines where the percentage of internal winnings for replay roles is changed for each type of bonus role, There is no degree of technical intervention on the part of the player in predicting the type of bonus combination that was won internally, and the player's technical intervention makes it possible to predict the internal winning of the bonus combination itself or the type of bonus combination that was won internally. There is a possibility that a high level of playability cannot be realized and a sufficient interest in the game cannot be secured.

  The present invention has been made in view of the above-described conventional problems, and is highly advanced by ensuring a high level of technical intervention for the player in predicting the internal winning of the bonus combination and the type of bonus combination won internally. The aim is to provide a slot machine that realizes a lot of playability and heightens interest.

The present invention includes a symbol variation display means including a symbol display unit that variably displays a plurality of types of symbols according to a predetermined arrangement in the symbol display area;
Game start operating means operated by the player to start the game;
An internal lottery for determining an internal winning combination from among a plurality of types including a first bonus combination, a second bonus combination, a normal replay combination, and a special replay combination, and an internal corresponding to the determined internal winning combination Internal lottery means for establishing a winning flag;
Stop operation means operated by the player to stop the variable display of the symbols in the symbol display section;
In response to an operation of the stop operation means, a display control means for drawing a symbol corresponding to the internal winning flag within a predetermined pull-in range and stopping and displaying it in the symbol display area;
Winning determination means for determining whether or not the symbol stopped and displayed by the symbol variation display means is a predetermined winning symbol;
A gaming state transition means for transitioning to a specific state which is a gaming state in which the internal lottery means determines the normal replay role as an internal winning combination with a higher probability than the normal state,
The internal lottery means plays the special replay combination in a first specific state that shifts according to the winning of the first bonus combination and a second specific state that shifts according to the winning of the second bonus combination. An internal lottery is performed so that the probability of being determined as an internal winning combination is different, and in the game in which the special replay role is determined as an internal winning combination, an internal lottery is performed so that the normal replay role is simultaneously determined as an internal winning combination. And
The predetermined arrangement in the symbol display unit is such that the symbols constituting the winning symbol for the normal replay role are located in the drawing range regardless of the operation timing of the stop operation unit, and the operation timing of the stop operation unit According to the present invention, there is provided a slot machine configured so that a case where a symbol constituting the winning symbol of the special replay combination is located within the drawing range and a case where the symbol is not located may occur. ).

  In the slot machine of the present invention, the first specific state and the second specific state in which the internal winning probability of the normal replay combination is higher than the normal state may occur. The first specific state is a gaming state that occurs in response to an internal winning of the first bonus combination, and the second specific state is a gaming state that occurs in response to an internal winning of the second bonus combination. is there. In this slot machine, the probability that the special replay combination is won internally differs between the first specific state and the second specific state. Therefore, in the slot machine, it can be predicted whether the player is in the first specific state or the second specific state in accordance with the winning frequency of the special replay combination. In the first specific state, the first bonus combination is won internally, and in the second specific state, the second bonus combination is won internally.

  Further, in the game in which the special replay role is determined as the internal winning combination, the slot machine simultaneously determines the normal replay role as the internal winning combination. In a game in which the normal replay combination and the special replay combination are determined as internal winning combinations at the same time, the winning probability of the special replay combination is lower than the normal replay combination due to the configuration of the predetermined arrangement. . That is, even if the special replay combination is determined as an internal winning combination, the player is more likely to miss the special replay combination unless the stop operation is performed at a predetermined operation timing. Considerable technical intervention is required in order to accurately predict whether or not a winner has been won and the type of bonus combination.

  In the slot machine of the present invention, the expectation for the internal winning of the first bonus combination or the second bonus combination is enhanced according to the winning of the normal replay combination. Furthermore, if the special replay role, which is harder to win than the normal replay role, can be awarded, the first specific state or the second specific state is determined according to the winning frequency of the special replay role. It is possible to predict whether it is in a state. Then, it is possible to predict the type of bonus combination won internally depending on whether the state is the first specific state or the second specific state.

  As described above, in the slot machine of the present invention, the player can feel by ensuring a high level of technical intervention of the player when predicting the internal winning of the bonus combination and the type of bonus combination that is won internally. The fun of gaming is enhanced. In particular, in the slot machine of the present invention, the internal winning of the bonus combination can be predicted according to the winning of the replay combination, so that it is possible to enjoy the prediction without reducing the game media on hand.

The slot machine of the present invention may be a slot machine in a narrow sense using medals and coins as game media, or a parrot (R) using pachinko balls as game media.
In addition, the special replay combination includes a first special replay combination in which the winning probability in the first specific state is higher than the winning probability in the second specific state, and the winning probability in the first specific state. There is a second special replay role with a higher probability of winning in the second specific state than
The symbol variation display means includes a plurality of symbol display units, and among the symbol display units, a symbol constituting the winning symbol for the first bonus combination and a symbol constituting the winning symbol for the second bonus combination are different. In the specific symbol display unit, the winning symbol of the first bonus combination is configured within the stop operation range of the stop operation means for stopping aiming at the symbol constituting the winning symbol of the first special replay combination. The pattern to be placed, and
In the specific symbol display unit, the symbols constituting the winning symbol of the second bonus combination within the stop operation range of the stop operation means for stopping aiming at the symbols constituting the winning symbol of the second special replay combination Is preferably arranged (claim 2).

Here, the stop operation range means an operation timing range of the stop operation means capable of stopping and displaying a specific symbol in the symbol display area in the predetermined arrangement of any symbol display unit. is doing.
If the expectation for winning the bonus role is enhanced by the game production or the stoppage of the design, many players will check whether the bonus role is won internally or the type of bonus role won internally At the same time, in order to win a bonus combination, a stop operation is performed aiming at a symbol corresponding to the bonus combination. However, even if the bonus combination is won internally, if the replay combination is simultaneously won internally, the replay combination will win. For this reason, when the replay combination is won at the same time, it becomes impossible to check whether the bonus combination is won internally or the type of bonus combination won internally. Also, if the replay role wins continuously, it is possible to check whether or not the bonus role has been won internally even if the player stops the game with the symbol corresponding to the bonus role. Not only is there no possibility of confirming the type of bonus combination won internally, and there is a risk that the fun of the game will be impaired. In this way, winning the replay role in a situation where the winning of the bonus role can be confident due to the above-mentioned stoppage or the like, there is a high possibility that the player will be frustrated. Furthermore, if the bonus for the bonus combination is missed in a game in which the replay combination has not been won internally, the possibility that the replay combination will win and win again in subsequent games becomes high.

  Therefore, in the specific symbol display section configured as described above, when the first bonus combination is won internally, the stop operation means is operated (so-called eyes) aiming at the symbol corresponding to the first bonus combination. Then, the symbol corresponding to the first special replay combination is stopped and displayed. In addition, when the second bonus combination is won internally, when the symbol corresponding to the second bonus combination is aimed at, the symbol corresponding to the second bonus combination is stopped and displayed. Therefore, when the winning probability of the first special replay role is high, the first specific state can be predicted, and when the winning probability of the second special replay role is high, the second specific state is predicted. Can be expected. In this case, in a game that is played for the purpose of determining whether or not the bonus combination has been internally won and the type of bonus combination, the replay role that was won internally won at the same time despite the aim of the bonus combination. Even so, the player can achieve the above-mentioned purpose. Therefore, the interest of the game can be enhanced.

  Further, the specific state generating means is configured to display the special replay more than the normal state when a specific symbol combination other than the winning symbol of the first bonus combination or the second bonus combination is stopped and displayed by the symbol variation display means. It is preferable that the third specific state in which the winning probability of the combination is increased is generated over a predetermined period (claim 3).

  In this case, in addition to the first specific state and the second specific state, the third specific state in which the winning probability of the special replay combination is increased can be generated. According to the third specific state, a sense of expectation for the bonus combination can be obtained even in a situation where the first bonus combination and the second bonus combination are not internally won. After that, the player can feel disappointed when he / she realizes that the bonus combination has not been elected internally, and can realize a rugged gameplay.

Further, the internal lottery means determines the special replay combination as an internal winning combination only during any one of the first specific state, the second specific state, and the third specific state. It is preferable that it is configured to be possible (claims 4 and 5).
In this case, the player's expectation for the internal winning of the first bonus combination and the second bonus combination can be effectively enhanced in accordance with the winning of the special replay combination.

The embodiment of the present invention will be specifically described with reference to the following examples.
Example 1
This example relates to the slot machine 1 that generates a specific state in which the internal winning probability of the replay combination is increased in accordance with the internal winning of the bonus combination. The contents will be described with reference to FIGS.
As shown in FIGS. 1 to 3, the slot machine 1 of this example includes a symbol display unit 21 (hereinafter referred to as a reel 21) that variably displays a plurality of types of symbols 20 in a symbol display area 110 according to a predetermined arrangement. Symbol variation display means 2, game start operation means 62 (hereinafter referred to as start lever 62) operated by the player to start the game, first bonus combination, second bonus combination, normal replay combination and special replay An internal lottery for determining an internal winning combination from among a plurality of types including a combination, an internal lottery means 42 for establishing an internal winning flag corresponding to the determined internal winning combination, and a symbol on the reel 21 In response to a stop operation means 61 (hereinafter referred to as a stop button 61) operated by the player to stop the variable display, and an operation of the stop button 61, The display control means 45 that draws the symbol corresponding to the internal winning flag within a predetermined pull-in range and stops it in the symbol display area 110, and the symbol that is stopped and displayed by the symbol variation display means 2 is a predetermined winning symbol. A winning determination means 49 for determining whether or not there is a game state transition means 44 for making a transition to a specific state, which is a gaming state in which the normal replay combination is determined as the internal winning combination with a higher probability than the internal lottery means 42 It is equipped with.

The internal lottery means 42 plays the special replay role as an internal winning combination in a first specific state that shifts in response to winning of the first bonus combination and a second specific state that shifts in response to winning of the second bonus combination. In the game in which the internal lottery is performed so that the probabilities to be determined as different from each other and the special replay role is determined as the internal winning role, the internal lottery is performed so that the normal replay role is simultaneously determined as the internal winning role.
The predetermined arrangement in the reel 21 is such that the symbols constituting the winning symbol for the normal replay role are located within the drawing range regardless of the operation timing of the stop button 61, and the special replay is performed according to the operation timing of the stop button 61. It is configured so that a case in which a symbol constituting a winning symbol of a combination is positioned within the pull-in range and a case where it is not positioned can occur.
Hereinafter, this content will be described in detail.

  First, the combination of the slot machine 1, the internal winning combination, and the winning combination will be described with reference to FIGS. In the slot machine 1 of this example, as shown in FIG. 3, a bonus combination, a small combination, a replay combination, and a Jacin combination are set. In FIG. 3, the names of the respective roles are shown in the left column, the winning symbols that are combinations of the respective symbols 20 are shown in the middle column, and the benefits (profit) to be given to the player according to the winnings are shown in the right column. In the slot machine 1, an internal winning combination by the internal lottery means 42 becomes an internal winning combination. When the winning symbol corresponding to the internal winning combination is established along the winning line, the winning combination becomes the winning combination.

  In the slot machine 1 of this example, as a bonus combination, two types of BIG bonus combinations (first BB combination and second BB combination) that are triggers of the BIG bonus game (BB game) and REG bonus game (RB game) are triggered. A REG bonus combination (RB combination) as a combination is set. As a small role, a role of plum, a role of bell, a role of watermelon, and a role of cherry are set. As replay roles, replay roles A to C are set. The Jacin combination is a winning combination that can be won only during the BB game.

  In this example, the first bonus combination and the second bonus combination are the first BB combination or the second BB combination. The first specific state is a first BB combination carry-over state that is an internal winning state of the first BB combination, and the second specific state is a second BB combination carry-over state that is an internal winning state of the second BB combination. Furthermore, a replay combination A is set as the normal replay combination, and a replay combination B and a replay combination C are set as the special replay combination. The replay combination B is a first special replay combination in which the winning probability in the first BB combination carryover state is higher than the winning probability in the second BB combination carryover state. The replay combination C is a second special replay combination in which the winning probability in the second BB combination carryover state is higher than the winning probability in the first BB combination carryover state.

  Next, the slot machine 1 of this example has an external configuration as shown in FIG. In the slot machine 1, the front portion facing the player is formed by a front frame body 10 having a substantially rectangular symbol display window 11 provided substantially at the center. The front frame 10 includes a liquid crystal display unit 530, a pair of left and right speakers 520, and a lamp unit 560 on the upper side of the symbol display window 11. A base 100 that forms the base of the slot machine 1 is formed below the symbol display window 11. On the right side of the symbol display unit 11, a credit display unit 551 and a payout number display unit 552 are arranged in the horizontal direction.

  As shown in FIG. 2, the base portion 100 is formed so as to protrude relatively toward the player with respect to the symbol display window 11 located behind the player. The base portion 100 has a table-like operation surface 14 at the upper end adjacent to the symbol display window 11, a medal tray 15 for paying out medals at the lower end, and a space between the operation surface 14 and the medal tray 15. An operation panel 13 is provided.

  As shown in FIGS. 1 and 2, the operation surface 14 has a bet button 64 for betting a credited (stored) medal, a credit settlement button 65 for paying out a credited medal, and a bet on a game. A medal insertion slot 630 for inserting medals is arranged. On the operation panel 13, a start lever 62 for starting the symbol variation of the reel 21 and a stop button 61 for stopping the symbol variation are arranged.

  As shown in FIGS. 1 and 2, the bet button 64 is a button for designating 3 bets, which is the maximum bet number, as the number of game bets. The bet button 64 basically generates a 3-bet signal representing the number 3 of game bets. However, when the remaining credit is 2 or 1, a 2-bet signal or 1-bet signal is generated, and when the credit is zero, a bet signal is not generated.

  As shown in FIGS. 1 and 2, the start lever 62 is an operation lever that generates a game start signal, which is a control signal for the reel 21, at a timing when the player operates. In the slot machine 1, the start lever 62 is set to the valid state on the assumption that a medal is inserted directly or a bet is bet by operating the bet button 64.

  The stop button 61 is an operation button that is generated at a timing when a player operates a variable stop signal that is a control signal of the reel 21. The stop button 61 of this example is a combination of a left stop button 61L corresponding to the left reel 21L, a middle stop button 61C corresponding to the middle reel 21C, and a right stop button 61R corresponding to the right reel 21R.

  As shown in FIG. 2, the symbol display window 11 is a display window including symbol display areas 110L, C, and R. Each of the symbol display areas 110L, C, and R is a symbol display area for three symbols. In the entire symbol display window 11, symbol display regions for nine symbols arranged in a two-dimensional matrix composed of three rows and three columns are formed. The symbol display window 11 is formed of a transparent resin plate so that the symbol 20 can be seen from the player side. For the nine symbols 20 arranged in a two-dimensional matrix, winning lines 211 to 215 that are the arrangement direction of winning symbols to be awarded are set. As the winning lines, there are horizontal winning lines 211 to 213 and diagonal winning lines 214 and 215.

  On the back side of each symbol display area 110L, C, R, reels 21L, C, R constituting the symbol variation display means 2 are respectively arranged as shown in FIGS. The reels 21L, 21C, and 21R are rotary reels having a substantially cylindrical shape and 21 symbols 20 arranged on the outer peripheral surface thereof at a substantially constant interval. The reel 21 may be an image-type reel that displays the symbols on the liquid crystal display in place of the rotary reel of this example.

  Here, in this example, the specific symbol display portion in which the symbol “white 7” corresponding to the first BB combination differs from the symbol “black 7” corresponding to the second BB combination is the middle reel 21C. Then, in the middle reel 21C that is the specific symbol display portion, a stop operation range (described later) that is an operation timing range for stopping the symbol “plum” corresponding to the replay combination B that is the first special replay combination B Thus, the symbol “white 7” corresponding to the first BB combination is arranged in the symbol numbers 17 to 21. Further, the middle reel 21C corresponds to the second BB combination in the stop operation range (symbol numbers 6 to 9 as will be described later) of the symbol “watermelon” corresponding to the replay combination C which is the second special replay combination. The pattern “Black 7” is arranged. A specific description of the stop operation range will be described in detail after the pull-in control by the display control means 45 is described.

The liquid crystal display unit 530 includes a liquid crystal display as shown in FIGS. The liquid crystal display unit 530 displays various effect screens for producing games.
The speaker 520 and the lamp unit 560 are rendering means for rendering a game with sound or light.
The credit display unit 551 is a display unit that displays the number of medals credited (stored) by the credit function.
The payout number display unit 552 is a display unit that displays the number of payout medals at the time of winning a prize.

Next, the slot machine 1 of this example has a mechanical configuration as shown in FIG.
A control board 3 that controls the overall operation of the slot machine 1 and each part that is electrically connected to the control board 3 will be described with reference to FIGS. 1 and 2. In addition to the above-described configuration, the control board 3 includes a inserted medal detection unit 63 that detects a medal inserted as a game medium, a reel drive unit 22 that forms the symbol variation display means 2 together with the reel 21, and rotation of the reel 21. Reference position detection unit 66 for detecting the position, medal paying unit 54 for paying out medals, various display units 55 including a credit display unit 551 and a payout number display unit 552, a lamp control board 56 for controlling lighting of the lamp unit 560, a player A set value operation unit 68 for setting a set value representing the degree of advantage of the sound, an audio control board 52 for controlling the speaker 520 (audio output unit), and a display control board 53 for controlling the liquid crystal display unit 530 are electrically connected. .

  As shown in FIGS. 1 and 2, the inserted medal detection unit 63 is a detection unit for medals inserted from the medal insertion port 630. The inserted medal detection unit 63 outputs an insert signal every time a medal is inserted from the medal insertion unit 630. In the slot machine 1 of this example, when a medal is inserted or when three medals are bet by operating the bet button 64, the start lever 62 is set to an effective state and the game can be started. Become.

  As shown in FIG. 1, the reel driving unit 22 includes a stepping motor (not shown) that can be controlled in units of steps, and is a means for rotationally driving the reel 21 by the rotational driving force of the stepping motor. The stepping motor rotates one step for each control pulse fetched from the control board 3. The reel drive unit 22 captures the variation start signal to start the rotation of the reel 21 and captures the variation stop signal to stop the reel 21.

As shown in FIG. 1, the reference position detector 66 is a detector that detects the passage of the reference position piece for each of the reels 21L, 21C, and R and outputs a detection signal.
As shown in FIG. 1, the medal payout unit 54 is a payout unit that pays out a predetermined number of medals to the medal tray 15 under the control of the control board 3.
As shown in FIG. 1, the set value operation unit 68 is an operation unit for changing a set value for setting the winning probability of a bonus combination or the like in six stages using a setting key 680.

  As shown in FIGS. 1 and 2, the control board 3 includes a CPU 31, ROM 33 and RAM 34 as memory means, an I / O unit 32 as an input / output interface, and a random number extraction unit 35 for extracting random numbers for internal lottery. And have. The CPU 31 executes a software program read from the ROM 33 to thereby display a winning determination means 49 for determining a winning symbol, a display control means 45 for controlling the reel 21, an internal lottery means for lottering an internal winning combination, and an internal winning flag. Each function as the flag control means 41 to control and the game state transition means 44 is realized.

  As shown in FIGS. 1 and 5, the ROM 33 as the memory means stores a winning random number table used by the internal lottery means 42 for the lottery of the internal winning combination. The winning random number table is a data table that defines winning random numbers for each winning combination. In this example, as shown in FIG. 5, a winning random number is set for each gaming state. In the figure, the range of winning random numbers for each winning combination to be won internally is defined by the opening price and the closing price.

  In the figure, the winning random numbers in the normal state column constitute a normal state table which is a winning random number table applied during the normal state. The winning random number in the first (second) BB handover status column is the winning applied to the first (second) BB handover status from when the first (second) BB hand wins to winning A first (second) BB carryover state table, which is a random number table, is configured. The winning random numbers in the RB handover status column constitute an RB handover state table that is a winning random number table applied to the RB handover state from when the RB hand wins the internal game until winning.

  The winning random numbers in the BB game column constitute a BB game table which is a winning random number table applied during the BB game. In this BB game table, winning random numbers for the BB role, RB role, and replay role are not set, and all winning random numbers are set as winning random numbers for the Jacin role. Therefore, in a game to which this BB game table is applied, the Jacin role can always be won internally. The winning random numbers in the RB game column constitute an RB game table which is a winning random number table applied during the RB game.

  Here, in the first (second) BB role carryover state table and the RB role carryover table, as shown in FIG. 5, the winning random numbers of the first (second) BB role and RB role are not set. The winning random numbers of the replay combination A are added as compared to the state, and the winning random numbers of the replay combination B and the replay combination C that are internally won simultaneously with the replay combination A are set. In the first BB combination carry-over state table, a random number range of 10678 to 32524 is defined as the winning random number of the replay combination A. On the other hand, a random number range of 10678 to 28155 is defined as the winning random number of the replay role B. Therefore, when the replay combination A is won internally, the replay combination B is simultaneously won internally with a probability of about 80%. Further, a random number range of 28156 to 30340 is defined as the winning random number for the replay combination C. Therefore, when the replay combination A is won internally, the replay combination C is simultaneously won internally with a probability of about 10%. In the game to which the first BB role carryover state table is applied, the replay roles B and C are not independently won internally, but the probability that the replay role A is independently won is about 10%.

  In the second BB combination carry-over state table, a random number range of 10678 to 32524 is defined as the winning random number of the replay combination A. On the other hand, a random number range of 10678 to 12863 is defined as the winning random number of the replay role B. Therefore, when the replay combination A is won internally, the replay combination B is simultaneously won internally with a probability of about 10%. Further, a random number range of 12864-30340 is defined as the winning random number of the replay combination C. Therefore, when the replay combination A is won internally, the replay combination C will be internally won with a probability of about 80%. In the game to which the second BB role carryover state table is applied, the replay roles B and C are not independently won internally, but the probability that the replay role A is independently won is about 10%. In the RB role carry-over state table, the probability that the replay role A and the replay role B are both internally won and the probability that the replay role A and the replay role C are simultaneously internally won are both about 10%.

  As described above, in the first BB combination carry-over state table, the second BB combination carry-over state table, and the RB carry-over state table, the replay combinations B and C have different probabilities for internal winning simultaneously with the replay combination A. In the first BB combination carry-over state table, there is a high probability that the replay combination B will win internally together with the replay combination A, and in the second BB combination carry-over state table, there is a high probability that the replay combination C will internally win together with the replay combination A. . On the other hand, in the RB role carryover state table, the replay roles B and C have the same probability of being internally won simultaneously with the replay role A.

  Furthermore, the ROM 33 stores a stop table used for stop control (retraction control) of the reel 21 as shown in FIG. The stop table is a data table that defines the number of drawn symbols (number of smooth frames) for each symbol arranged on the reel 21. The number of drawn symbols is a variable symbol number until the reel 21 is actually stopped when the stop button 61 is operated at the moment when the corresponding symbol is positioned on the winning line 212. The pull-in control by the stop table will be described in detail later.

  As shown in FIG. 1, the random number extraction unit 35 is a part that extracts a random number for internal lottery. The random number extraction unit 35 extracts a random number from the integers generated by the random number generation unit 350. The random number generator 350 is a part that generates an integer belonging to the range of 0 to 65535 (decimal number display). The random number extraction unit 35 samples an integer generated by the random number generation unit 350 using a game start signal corresponding to the operation of the start lever 62 as a trigger (trigger), and extracts it as a random number for internal lottery. The random number extracted by the random number extraction unit 35 becomes a random number for internal lottery for the internal lottery means 42 to draw the internal winning combination.

  As shown in FIG. 1, the internal lottery means 42 is a means for determining an internal winning combination by internal lottery and establishing an internal winning flag corresponding to the internal winning combination. The internal lottery means 42 determines the internal winning combination by collating the random number extracted by the random number extraction unit 35 against the winning random number of each combination specified in the winning random number table. The internal lottery means 42 in this example selectively uses one of the winning random number tables in FIG. 5 according to the gaming state.

  As shown in FIG. 1, the flag control means 41 is a means for controlling an internal winning flag representing a state where each winning combination can be won. For the internal winning flags of the other combinations other than the first BB combination, the second BB combination, and the RB combination, the flag control means 41 determines whether the next game is won regardless of whether the internal winning flag is won in the first game. Reset to off state (zero) before starting. According to such control of the flag control means 41, when each combination other than the first BB combination, the second BB combination, and the RB combination is not won in the internal winning game, all are lost. On the other hand, with regard to the first BB combination flag, the second BB combination flag, and the RB combination flag, which are internal winning flags of the first BB combination, the second BB combination, and the RB combination, the establishment state of the internal winning flag is set in the next game until winning. It is sequentially carried over and reset to the off state in response to winning.

  The game state transition means 44 is a means for generating various game states such as first and second BB carryover states and BB (BIG bonus) games. In this example, the first and second BB carryover states are set as the first specific state or the second specific state. The game state transition means 44 generates the first (second) BB combination carry-over state while the first (second) BB combination flag, which is an internal winning flag, is being established (ON state). In the first (second) BB handover state, the first (second) BB handover state table is applied to the internal lottery means 42. Further, when the RB combination flag is on, an RB combination carry-over state occurs, and the RB combination carry-over state table is applied to the internal lottery means 42.

  Further, in the gaming state transition means 44, a control flag for controlling the gaming state generated by the slot machine 1 is set. The control flag includes a BB game flag corresponding to a BB (BIG bonus) game, an RB game flag corresponding to an RB (REG bonus) game, and the like. The game state transition means 44 applies the BB game table to the internal lottery means 42 when the BB game flag is on, and the RB game table to the internal lottery means 42 when the RB game flag is on. Apply. On the other hand, when the first (second) BB combination flag, the RB combination flag, the BB game flag, and the RB game flag are all in the off state, the game state transition unit 44 transfers the normal state table to the internal lottery unit 42. Apply.

  The BB game flag is switched to the on state in response to the winning of the first (second) BB role, and is reset to the off state when the cumulative payout number of medals in the BB game exceeds a prescribed number of 465. Is done. The RB game flag is turned on in response to the winning of the RB role, and when the number of winning games in the RB game reaches 8 that is the prescribed number of games, or 12 times that the number of digested games is the prescribed number of games. Is reset to the off state (zero).

  As shown in FIGS. 1 and 2, the winning determination means 49 is a means for determining whether or not the combination of symbols stopped and displayed on the three reels 21L, 21C, 21R is a predetermined winning symbol. Specifically, the winning determination means 49 determines the winning combination according to the combination of symbols stopped on the winning lines 211 to 215 set so as to cross the three reels 21L, 21C, 21R. The winning determination means 49 captures the number of steps related to each stepping motor (reel drive unit 22) corresponding to each reel 21L, C, R after each reel 21L, C, R stops. The winning determination means 49 obtains the type of the symbol 20 stopped on the winning lines 211 to 215 based on the number of steps, and determines whether or not a winning combination is established for the combination of the symbols 20. The winning determination means 49 instructs the medal paying unit 54 on the number of medals to be paid out (see FIG. 3) according to the type of winning combination.

  As shown in FIGS. 1 and 2, the display control unit 45 is a unit that controls symbol variations of the reels 21 </ b> L, C, and R via the reel driving unit 22. The display control means 45 starts the symbol fluctuation of the reel 21 in response to the game start signal and stops the symbol fluctuation of the reel 21 in response to the fluctuation stop signal. The display control means 45 inputs a control pulse to the stepping motor constituting the reel driving unit 22 and rotates the stepping motor by one step for each pulse. The display control means 45 counts the number of control pulses input to the reel drive unit 22, that is, the number of steps rotated by the stepping motor. In particular, in this example, the number of steps generated after the latest detection signal can be counted by resetting the number of steps of each reel 21 to zero each time a reference position piece detection signal is received by the reference position detector 66. It is said.

  As shown in FIG. 1, the display control means 45 stops the reel 21 within the pull-in control range defined by rules (rules concerning the recognition of the gaming machine and the type test) after the stop operation of the stop button 61. It is comprised so that control may be implemented. In this example, a range corresponding to four symbol variations is set as the pull-in control range. The display control means 45 can calculate the symbol currently displayed on each reel 21L, C, R (the symbol located on the winning line) based on the number of steps.

  The display control means 45 calculates the bita symbol, which is the symbol 20 instantaneously located on the winning line 212, based on the number of steps at the time when the fluctuation stop signal is taken in, and collates it with the stop table stored in the ROM 33. To do. The display control means 45 acquires the number of drawn symbols specified for the bita symbol, pulls in the symbols for the number of drawn symbols, and stops the reel 21. The display control means 45 of this example preferentially stops the symbol corresponding to the replay combination when the bonus combination and the replay combination are simultaneously won internally.

  Next, the operation of the slot machine 1 of this example configured as described above will be described with reference to FIGS. FIG. 7 is a flowchart showing the flow of the game start process. FIG. 8 is a flow showing the flow of the winning process.

  The flow of the game start process will be described with reference to FIG. Here, first, a start operation, that is, an operation of the start lever 62 is determined as in step S101. When the start lever 62 is operated, a random number for internal lottery is acquired as in step S102. In steps S104 to S108, the flag states of the first BB combination flag, the second BB combination flag, the RB combination flag, the RB game flag, and the BB game flag are determined. A winning random number table (see FIG. 5) for random number verification is selected in accordance with the established flag.

  When the first BB combination flag is 1 (on state) (step S104), random number verification is performed using the first BB combination carry-over state table as in step S125. When the second BB combination flag is 1 (on state) (step S105), random number verification is performed using the second BB combination carry-over state table as in step S126. If the RB combination flag is 1 (ON state) (step S106), random number verification is performed using the RB combination carry-over state table as in step S127.

  When the RB game flag is 1 (ON state) (step S107), random number verification is performed using the RB game table as in step S128. If the BB game flag is 1 (ON state) (step S108), random number verification is performed using the BB game table as in step S129. When the first BB combination flag (step S104), the second BB combination flag (step S105), the RB combination flag (step S106), the RB game flag (step S107), and the BB game flag (step S108) are all off. As in step S109, random number matching is performed using the normal state table. Then, as in step S110, the internal winning combination flag is set to 1 (on state), and the reel 21 starts to rotate as in step S111.

  The flow of the winning process will be described with reference to FIG. In step S201, it is determined whether to stop the left reel 21L, that is, press the left stop button 61L. When the left stop button 61L is pressed, the left reel 21L is stopped as in step S202. In step S251, a stop operation on the middle reel 21C, that is, a depression operation of the middle stop button 61C is determined. When the middle stop button 61C is pressed, the middle reel 21C is stopped as in step S252. In step S261, it is determined whether to stop the right reel 21R, that is, press the right stop button 61R. When the right stop button 61R is pressed, the right reel 21R is stopped as in step S262. As in step S203, the above-described processing is repeatedly performed until all the reels 21L, C, and R are stopped.

  When all the reels 21 are stopped (step S203), the process proceeds to step S204 to determine whether or not the symbol stopped on the winning line is a winning symbol. If any of the replay roles A to C has won as in step S205, the replay game is set (step S206), and all of the replay role flags A to C that are internal winning flags of the replay role that has been won internally. Is reset to zero (off state) (step S207).

  When the first (second) BB combination is won as in step S226, the BB game flag is set to 1 (ON state) (step S227), and the first (second) BB combination flag is zero ( (OFF state) is reset (step S228). If the RB combination or Jacin combination is won as in step S237, the RB game flag is set to 1 (on state) (step S238), and the RB combination flag or Jacin flag is reset to zero (off state). (Step S239). If the small combination is won as in step S248, after the payout process P1 is performed, the internal winning flag of the small combination is reset to zero (off state) (step S249).

  Thereafter, the process proceeds to step S208, and it is determined whether or not the BB game end condition is achieved. When the BB game end condition is achieved, the BB game flag is reset to zero (OFF state) as in step S209. If the BB game end condition is not achieved, step S209 is bypassed. In the subsequent step S210, it is determined whether or not the RB game end condition has been achieved. When the RB game end condition is achieved, the RB game flag is reset to zero (off state) as in step S211. On the other hand, when the RB game end condition is not achieved, step S211 is bypassed.

  Next, a specific example of the pull-in control of the middle reel 21C in the game to which the stop table illustrated in FIG. 6 is applied will be described with reference to FIG. This figure is a stop table applied to the first BB handover state (first specific state) or the second BB handover state (second specific state). As shown in FIG. 6, six patterns of stop tables are prepared in accordance with the internal winning status of the replay combination.

  Among the patterns illustrated in FIG. 6, patterns 1, 2, and 5 are stop tables applied to the first BB carryover state, and patterns 3, 4, and 6 are stops applied to the second BB carryover state. It is a table. Furthermore, patterns 1 and 3 are stop tables that are applied in a state where the replay combination flag A that is the internal winning flag of the replay combination A and the replay combination flag B that is the internal winning flag of the replay combination B are simultaneously established. Patterns 2 and 4 are stop tables applied in a state where the replay combination flag A and the replay combination flag C are simultaneously established. Patterns 5 and 6 are stop tables applied when the replay combination flag is not established. In FIG. 6, the illustration of the stop table that is applied when only the replay combination flag A is established as the replay combination flag is omitted. In this case, the middle stop button 61C is operated at any timing. Even so, the symbol “R” of the replay combination A can be stopped and displayed.

  In a game to which the stop table of pattern 1 or pattern 3 is applied, if the middle stop button 61C is operated (stop operation) at the moment when the symbols of symbol numbers 1 to 16 are positioned on the winning line 212, the replay role The symbol “R” of A can be drawn into the symbol display area 110C and stopped. When the stop operation is performed at the moment when the symbols of symbol numbers 17 to 21 (hatched portions in each pattern) are positioned on the winning line 212, the symbol “Plum” of the replay combination B can be stopped and displayed.

  On the other hand, in a game to which the stop table of pattern 2 or pattern 4 is applied, the middle stop button 61C is operated at the moment when the symbols of symbols 1 to 5 or symbols 10 to 21 are positioned on the winning line 212. When the (stop operation) is performed, the symbol “R” of the replay combination A can be drawn in and stopped. When the stop operation is performed at the moment when the symbols of symbol numbers 6 to 9 are positioned on the winning line 212, the symbol “watermelon” of the replay combination C can be stopped and displayed.

  In the game to which the patterns 1 to 4 are applied, in order to stop aiming at the symbol corresponding to the special replay role, it is necessary to operate the middle stop button 61C in the hatched portion in each pattern. That is, the stop operation range of the symbols corresponding to the replay combinations B and C that are the special replay combinations is very narrow compared to the stop operation range of the symbols corresponding to the replay combination A that is the normal replay combination. Therefore, in the game to which the patterns 1 to 4 are applied, in order to win the replay roles B and C that are special replay roles, a certain amount of skill is required.

  Here, in the middle reel 21 </ b> C, the symbol “white 7” corresponding to the first BB combination is arranged at symbol number 20. The symbol “white 7” is arranged in the stop operation range (symbol numbers 17 to 21) of the symbol “plum” of the replay combination B. Therefore, in a game to which patterns 1 and 3 are applied, when aiming at the symbol “white 7” corresponding to the first BB role, the symbol “plum” corresponding to the replay role B is drawn with a high probability. Stop can be displayed. As for the replay role B, which is a special replay role, as described above, the simultaneous winning probability with the replay role A in the first BB role carryover state is about 80%, while the replay role A in the second BB role carryover state and The simultaneous winning probability is about 10%. Therefore, when the symbol of the replay combination B is stopped and displayed on the middle reel 21C, it is possible to predict that there is a high possibility that the first BB combination flag is being established.

  Here, in the middle reel 21 </ b> C, the symbol “black 7” corresponding to the second BB combination is arranged at symbol number 8. The symbol “black 7” is arranged within the stop operation range (symbol numbers 6 to 9) of the symbol “watermelon” of the replay combination C. Therefore, in a game to which patterns 2 and 4 are applied, when aiming for the symbol “black 7” corresponding to the second BB role, the symbol “watermelon” corresponding to the replay role C is drawn with a high probability. Stop can be displayed. Regarding the replay role C, which is a special replay role, as described above, the probability of simultaneous winning with the replay role A in the first BB role carryover state is about 10%, while the replay role A in the second BB role carryover state and The probability of winning simultaneously is about 80%. Therefore, when the symbol of the replay combination C is stopped and displayed on the middle reel 21C, it is possible to predict that there is a high possibility that the second BB combination flag is being established.

  Furthermore, as shown in FIG. 6, when the stop table of pattern 2 and the stop table of pattern 4 are compared, only the number of symbols drawn in symbol number 7 is different. Therefore, if the stop operation is performed at the moment when the symbol No. 7 is positioned on the winning line 212, the type of the BB combination for which the internal winning flag is established according to the type of the symbol stopped on the middle reel 21C. It is also possible to determine.

  In the game to which the pattern 5 and the pattern 6 applied in a state where the first BB combination flag or the second BB combination flag is established, if the middle stop button 61C is operated in the hatched portion in each pattern, the first BB combination The symbol “white 7” corresponding to the symbol “2” or the symbol “black 7” corresponding to the second BB combination may be stopped and displayed. The stop display of the symbol “black 7” in the established state of the first BB combination flag and the stop display of the symbol “white 7” in the established state of the second BB combination flag can be reach marks that are so-called unique loss patterns.

  As described above, in the slot machine 1 of the present example, the player can enjoy the prediction of the bonus combination that is won internally according to the winning of the special replay combination (replay combination B, C) in the first (second) BB combination carryover state. be able to. In this slot machine 1, it is difficult to win the replay roles B and C, which are special replay roles, as compared to the replay role A, which is a normal replay role. Therefore, in the slot machine 1 of this example, a high level of playability is realized in which an internal winning of a bonus combination can be predicted for the first time by a player's technical intervention to win a special replay combination that is difficult to win.

  Instead of this example, the period during which the special replay combination can be won internally is not the entire period of the first (second) BB combination carry-over state, but the predetermined period after the first (second) BB combination has won internally. You may limit to. For example, five games after the internal winning of the first (second) BB combination can be set as a period during which the special replay combination can be won internally.

  In addition, the third specific state in which the special replay combination can be won internally may be generated over a predetermined period in response to a winning of a specific combination in a normal state or a chance stop that is a specific symbol combination. Further, in this case, the winning of the specific combination or the chance stop may be generated not only in the normal state but also in the first (second) BB combination carryover state. Furthermore, a special replay combination may be internally won in the normal state. In this case, the internal winning probability of the special replay combination in the normal state is preferably set to be extremely lower than the internal winning probability of the special replay combination in the first (second) BB carryover state.
