2. Description of the Related Art Conventionally, in a slot machine in which a lottery for winning is performed and a control device controls stop of a rotating reel based on a result of the lottery, a stepping motor is used to rotate a rotating reel having a start index. The current position of the symbol is detected by the number of rotation steps after the start index is detected by the sensor, and the control for stopping the predetermined symbol at the predetermined position is performed.

Specifically, when the start switch is operated, the pulse transmission device of the control device transmits a pulse signal, and the stepping motor starts rotating. When the sensor detects the start index of the rotary reel, the pulse signal transmitted by the pulse transmitter is counted with reference to the time when the start index is detected. Further, the control device stores the range of the number of steps corresponding to each symbol, that is, the number of steps from the reference and what symbol is the number of steps, with the rotation distance of the rotating reel rotated by one pulse as one step. ing. The step position at the time when the stop switch is operated is stored, and the symbol to which the step position belongs can be specified.

On the other hand, although the gaming machine is formed to be able to change the lottery probability of the lottery related to winning according to predetermined conditions, the lottery probability is simply related to the operation of the stop switch regardless of whether or not the player wins. There was no control to change it.

It is equipped with "Replay" that allows the player to play a game. When the lottery result is any winning, the winning flag corresponding to the winning is established. Then, if the lottery result is a special winning, the special winning flag is established, and while the special winning flag is being established, the stop symbol of the rotating reel 40 of the reel unit 60
61 combinations are the predetermined special winning symbols
61 (for example, three "7" s are lined up on the winning pay line), the player wins a prize on the condition that the player can play an advantageous special game. On the other hand, the special winning flag has been established by the lottery, but if the combination of the stop symbols 61 of the rotating reel 40 does not match the special winning symbol 61, the right to hold the special winning flag is carried over to the subsequent games. Is set to. If the winning flag of the small winning combination cannot be won in the game in which the winning flag is established, the right to establish the winning flag is not carried over to the next game.

In addition, while one of the winning flags is established,
Whether or not the corresponding winning symbols 61 can be arranged on the winning effective line depends on the timing of the stop switch 50 when the rotation speed of the rotating reel 40 is constant. Specifically, after operating the stop switch 50, 1
Since the rotating reel 40 is set to stop within 90 ms, after operating the stop switch 50, it can be stopped as it is, or a retractable symbol 61 on the circumference of the rotating reel 40 that can be stopped within 190 ms, For example, when the corresponding winning symbol 61 is included in the four retractable symbols 61 that are continuous from the stop symbol, the time until stopping is delayed and the rotary reel 40 is on the winning effective line. It draws in the winning symbol 61 and stops. on the other hand,
If the corresponding winning symbol 61 is not included in the four retractable symbols 61, the winning symbol 61 cannot be pulled in and stopped on the winning effective line.

(Special game control means 80) Special game control means
80 is for making the player perform an advantageous special game based on the lottery result of the lottery means. The special games are roughly classified into the following games. (1) Specific introduction game (BB game) (2) Specific game (RB game) (3) Specific prize game (JAC game) Note that a specific game, for example, an RB game, is a specific introduction game,
For example, it may be performed during the BB game, or may be performed independently even when the BB game is not performed. The specific winning game, so-called JAC game, is played during the RB game. Further, the special game is not limited to the above-mentioned games (1) to (3).
For example, a replay time game in which the winning probability of the "replay" is set high may be provided over a predetermined period.

The special game control means 80, as shown in FIG. 1, roughly includes the following means. (1) Specific introduction game control means 91 (BB game control means 9
0) (2) Specific game control means 101 (RB game control means 100) (Specific introduction game control means 91) Specific introduction game control means 91
Is for controlling the BB game.

Specifically, in a normal game, although not shown, for example, when three symbols 61 such as "7" are lined up on the winning effective line, for example, 15 medals are paid out through the hopper unit 65. . At this time, the BB game is started. When the game shifts to the BB game, it starts by inserting a maximum of three medals as in the normal game, and when the rotations of the three rotating reels are stopped, depending on whether or not the winning symbols are aligned on the winning effective line. , Medals are paid out.

Therefore, during the BB game, a lottery including small wins is performed every time as in the normal game.
However, when the specific winning symbols for shifting to the RB game are aligned on the winning effective line during the BB game, the RB game is subsequently shifted. Note that normally, B
During the B game, the transition to the RB game is to be performed, for example, up to three times. Therefore, after the first RB game is finished, the lottery and control similar to the normal game as described above are performed. It is done.

In the BB game, the RB game in the BB game is a predetermined maximum number of times, for example, three times, or B
The normal game during the B game has a predetermined maximum number of times, for example, maximum 3
The BB game ends when the game ends 0 times. (Specific game control means 101) The specific game control means 101 is an RB
It is for controlling the game.

Specifically, when shifting to the RB game, one medal is inserted, and when a predetermined symbol 61 of the rotary reel 40 is aligned on the center line of the display window 12, a specific winning game is won. It is something that will be done. Then, in the RB game, a specific winning game as to whether or not to win is possible up to 12 times, of which a maximum of 8 times can be won. That is, you can win a maximum of 8 times, or a maximum of 12
The RB game ends when the specific winning game is ended.

(Winning lottery means 110) The winning lottery means 110 is
A lottery for determining whether or not the player wins is performed based on a predetermined lottery probability. Then, the winning flag is established when the lottery result by the winning lottery means 110 is a winning, and while the winning flag is being established, on the condition that the combination of the stop symbols of the rotary reel 40 matches the predetermined winning symbol. It is set so that a player wins a prize and pays out a medal or a special game.

The winning lottery means 110, as shown in FIG. 1, roughly includes the following means. (1) Random number generating means 111 (2) Random number extracting means 112 (3) Winning determination table 113 (4) Judging means 114 The winning lottery means 110 is limited to the above (1) to (4). is not.

(Random Number Generating Means 111) The random number generating means 111 is
Random number for winning lottery within a predetermined area (for example, 0 in decimal)
65535). (Random Number Extracting Unit 112) The random number extracting unit 112 is a random number generating unit.
The random number generated by 111 is extracted under a predetermined condition (for example, operation of the start switch 30). The extracted random number is used as extracted random number data.

Here, as the "random number generating means",
In addition to the one that can generate a random number by the average sampling method or the like as a soft random number, it may be configured by using a counter that increments numbers in a certain range one by one at high speed. For example, a counter in which a number in the range of 0 to 16383 is sequentially repeated about 7 million times per second can be considered.
As the "random number extracting means", the number on the counter is read at the timing when the start switch is pressed.

When formed in this manner, "random number generating means"
However, although the random numbers are not generated, the numbers extracted by the "random number extraction means" have a distribution as if they were random numbers. In this way, means for obtaining numbers showing a distribution such as random numbers as a result is considered to be included in the "random number generating means" or the "random number extracting means".

(Winning determination table 113) The winning determination table 113 has a winning area for each winning item in the entire area of the random numbers taken by the random number generating means 111. Here, as the winning determination table 113, a plurality of sets are provided according to the setting of the slot machine 10, the number of inserted medals, and the like. An example thereof is shown in FIG.

FIG. 6 schematically shows the winning determination table 113 provided for each setting. Slot machine 1
The setting of 0 is divided into ranks from setting value 1 to setting value 6, and normally, which setting is to be decided by operating the setting changing device provided inside the slot machine. The probability of winning the winning combination (winning probability) varies depending on the difference in the set value.
For example, the set value 6 is formed so as to have a higher probability of being a “win” than the set value 1.

More specifically, as shown in the drawing, a plurality of winning determination tables 113 for the normal game and the special game are provided for each setting, and these winning determination tables 113 are provided.
The average of the winning probabilities of is the winning probability of each setting. If the winning probability is high, the chances of winning will naturally increase, so by adjusting the set value, the amount of relative payout medals of the gaming machine changes.

The winning determination table 113 for the normal game is the winning determination table 113 used during the normal game. This is provided with a low probability table in which the winning probability is set low and a high probability table in which the winning probability is set high according to the number of inserted medals. Note that "low probability" and "high probability" are relative, and "low probability"
Is lower than “high probability”, and “high probability” is higher than “low probability”. Specifically, the high-probability table is a winning determination table having a smaller “miss” area than the low-probability table.

Winning determination table 113 corresponding to the number of inserted coins
Is set so that the winning probability is higher when three cards are inserted than when one card is inserted. This is because the number of activated pay lines increases as the number of inserted coins increases, and in the case of winning, there is a high possibility that the winning symbols can be arranged. When the number of inserted medals is one, the winning determination table 113 for one win is used, and when the number of inserted medals is three, the win determination table 113 for three wins is used to perform a lottery on winning. Whether the high probability table or the low probability table is used is determined by the lottery probability changing means 130 described later.
Based on the decision of.

Also, the winning determination table 113 for special games
Is a winning determination table 113 used in a special game. This is provided with a winning determination table 113 having different types of winning regions for each type of game. For example, RB
At the time of the game, for a specific symbol, for example, a "replay" symbol, the table has only a "win" or "miss" area. Further, in the RT game, that is, during the replay time game, the table structure is such that the "replay" area is set wide.

The winning determination table 113 is not limited to the one described above, and the winning determination table 11 having another configuration is used.
You may have 3. For example, a table in which the BB winning area is set wide, or a table in which the winning probability is set between the low probability table and the high probability table may be provided. (Determination means 114) The determination means 114, based on the extracted random number data extracted by the random number extraction means 112 and the lottery probability data of the winning determination table 113, of each winning item in all areas of the random numbers taken by the random number generating means 111. The winning determination area data including the winning area is collated to determine the winning corresponding to the winning area to which the extracted random number data belongs.

(Rotation Stop Control Device 120) The rotation stop control device 120 is for controlling the rotation reel 40 to stop. The rotation stop control device 120 has the following means (1) to (4) as shown in FIG. (1) Stop table 121 (2) Step unit table 122 (3) Step position measuring means 123 (4) Rotation stop executing means 124 The rotation stop control device 120 has the above-mentioned (1).
It is not limited to the means of (4) to (4), and other means may be included.

(Stop Table 121) The stop table 121 is
How many frames are rotated from a predetermined symbol to stop the rotating reel 40 is defined for each symbol according to a predetermined condition. Specifically, when the winning flag is established,
The stop position is determined in advance on the table so that the symbols corresponding to the winning flag are lined up on the winning effective line, and the other winning symbols are not lined up on the winning line, so-called pull-in setting. It is equipped with a kind of. Also, when the winning flag is not established,
The stop position is determined in advance on the table so that no winning symbols are lined up on the winning line, and a kind of so-called kick-off setting is provided.

The stop table may be created assuming that the stop switch 50 is operated at all positions for each symbol, but since all combinations must be made for each symbol, the number of tables is It becomes huge. Therefore, the stop position candidate may be determined according to the stop table, and the stop symbol may be determined while determining the validity of the candidate. Stop control in this case, the bit corresponding to the winning symbol, the winning symbol that should be stopped and the symbol that should not be stopped, respectively provided, based on the data stored in the bit, the stop position candidate is appropriate In that case, it is stopped at that position, and if it is not appropriate, another appropriate position is determined and stopped.

(Step Unit Table 122) The step unit table 122 defines a predetermined step unit with the total number of steps of the stepping motor as the entire area. The step unit table 122 includes the stop switch 5
This is for specifying the symbol corresponding to the step position at the time of 0 operation.

Here, a specific example of the step unit table 122 will be described with reference to FIG. In the figure, alphabets represent symbols, and numbers represent step positions. The reference point indicates the position of the start index. FIG. 5A is a diagram showing the relationship between the symbol 61 of the rotating reel 40 and the step position. That is, it is a diagram schematically showing the unfolded reel tape 42, in which each symbol 61 shows how many steps from the reference point is located in the range from what step to how many steps. . For example, the symbol A indicates that it is located between the step position 492 and the step position 12.

FIG. 5B schematically shows the step unit table 122. In the step unit table 122, the number obtained by dividing the total number of steps (for example, 504 steps) of the stepping motor during one rotation of the rotary reel 40 by the number of the symbols 61 (for example, 21),
It is the number of steps that make up one step unit,
According to the number of steps from the reference point, a step unit corresponding to a predetermined symbol 61 (referred to as a symbol corresponding step unit. The same applies hereinafter) is specified. For example, the range of 120 to 144 steps from the reference point is
It is said to be a step unit corresponding to the "design Q".

The symbol corresponding step unit defined in the step unit table 122 shown in FIG. 5 (B) is the rotation direction with respect to the actual symbol position on the rotary reel 40 shown in FIG. 5 (A). The number of steps is provided in the opposite direction in consideration of the time from the operation of the stop switch 50 to the stop of the design including the inertia of the rotary reel 40 facing the front.

(Step position measuring means 123) The step position measuring means 123 counts the number of rotation steps of the stepping motor from the reference point, and according to the count value,
This is for recognizing the step position when the stop switch 50 is operated and for identifying the symbol corresponding to the step position.

Specifically, the step position measuring means 123
Although not shown in particular, has a counting means, a storage means, and a determination means. The counting means counts the pulse signals transmitted by the pulse transmission device in the control device 20. Specifically, the rotating reel 40 starts rotating, and when the index sensor first senses the start index, a detection signal is emitted. The counting means that has received the signal starts counting the number of steps with the step position at the time of receiving the signal as a reference point. Then, the count value is cleared each time the rotary reel 40 makes one revolution, that is, each time the start index is detected, and the count is repeated again from 1.

The storage means is for storing the count value of each rotating reel 40 when the operation signal of the stop switch 50 is received. The determination means recognizes the count value stored in the storage means as the step position for each of the rotating reels 40, and the step unit table 122
In contrast to this, the symbol corresponding step unit to which the step position belongs is specified. For example, when the stop switch 50 is operated at the step position 12 in FIG. 5B, the step unit corresponding to the "design A" is specified.

The step position measuring means 123 sends the information of the step unit corresponding to the symbol of each rotating reel 40 specified as described above to the rotation stop executing means 124 described below, and at the same time receives the operation signal of the stop switch 50. Information of the step position at that time is sent to the winning probability changing means 130 described later. (Rotation stop executing means 124) The rotation stop executing means 124 is for stopping the rotating reel 40 based on a predetermined stop table 121 based on the lottery result of the winning lottery means 110 and the symbol when the stop switch 50 is operated. Is.

Specifically, the rotation stop executing means 124 specifies the information of the step corresponding to the symbol received from the step position measuring means 123 as the symbol when the stop switch 50 is operated, and is selected by the winning lottery means 110. Based on the stop table 121, the stepping motor is rotated to move the symbol 61 of the rotary reel 40 by a predetermined number of frames, or the symbol is stopped at that position.

(Lottery Probability Changing Means 130) The lottery probability changing means 130 determines the lottery related to winning performed by the winning lottery means 110 based on the step position at which the stop switch 50 is operated (hereinafter referred to as the operation position of the stop switch 50). It is for changing the probability. The lottery probability changing means 130 has the following means (1) to (4) as shown in FIG.

(1) Step position storage means 131 (2) Probability change determination table 132 (3) Setting change means 133 (4) Winning determination table change means 134 As the lottery probability change means 130, the above (1) to The means is not limited to the means of (4), and other means may be included.

(Step position storage means 131) The step position storage means 131 inputs the step position information at the time of receiving the operation signal of the stop switch 50 output from the step position measuring means 123 of the rotation stop control means 120, It is for memory. Here, the step position storage means 13
One may store the operation position of the stop switch 50 for any one of the three rotation reels 40, or the operation position of the stop switch 50 for the plurality of rotation reels 40. It may be stored.

When the operation position of the stop switch 50 for any one of the rotating reels 40 is stored, the rotating reel 40 may be predetermined or may be determined by lottery for each game, for example. . When the operation positions of the stop switch 50 for the plurality of rotating reels 40 are stored, for example, the stored plurality of positions (the number of steps)
Can be calculated and stored.

(Probability Change Judgment Table 132) The probability change judgment table 132 defines the data area for changing the lottery probability, with the total number of steps (eg, 504 steps) of the stepping motor as the entire area. Then, the probability change determination table 132 includes the stop switch 50
This is for specifying the setting of the slot machine 10 or the winning determination table 113 corresponding to the step position at the time of operation.

Here, a specific example of the probability change determination table 132 will be described with reference to FIG. FIG. 5C schematically shows the probability change determination table 132.
In the drawing, or represents the type (index) of data for changing the lottery probability. Probability change judgment table 132
The data area for changing the lottery probability is defined in the entire area indicating the total number of steps of the stepping motor during one rotation of the rotary reel 40, and the predetermined area is set according to the number of steps from the reference point. Setting or winning decision table
113 is to be specified.

For example, in FIG. 5C, the step position 504 to the step position 24 is a data area. This is a portion corresponding to the symbol A in relation to the symbol position of the rotary reel 40. Then, when the stop switch 50 is operated within the range of this step unit, the probability change corresponding to the data is performed.

The area indicated by is a portion between the symbol O and the symbol P in relation to the symbol position of the rotary reel 40 (see FIGS. 5A and 5C). Then, when the stop switch 50 is operated within the range of this step unit, the probability corresponding to the data is changed. Further, the area indicated by is the symbol D in relation to the symbol position of the rotating reel 40. It becomes the central part of. Then, when the stop switch 50 is operated within the range of this step unit, the probability change corresponding to the data is performed.

As described above, by forming the lottery probability to be changeable in correspondence with the step unit of a range different from the step unit corresponding to the symbol, even if the same symbol 6 stops at the same position, the probability is changed. Since it may or may not occur, it is possible to make the game surprising. Further, since the blank portion does not store any data regarding the probability change, when the stop switch 50 is operated in this range, the probability change is not performed. In this case, the winning probability used for the game may be carried over to the next game, or may be formed so as to return to the initial setting.

Although not particularly shown, the lottery probability changing means 130 is provided with a judging means. By comparing the step position information stored in the step position storing means 131 with the probability changing judgment table 132, Identify probability change data. Then, the probability changing process is performed based on the data. For example, if the probability change is of the form of “changing the setting”, the setting changing unit 133, which will be described later, starts its operation and executes a predetermined setting change.
If the probability change is of the form of "changing the win determination table", the win determination table changing means 134, which will be described later, starts its operation and executes a predetermined win determination table change. If the data could not be specified, the probability is not changed.

The probability change determination table 132 is not limited to the above-mentioned configuration. Further, a plurality of probability change determination tables 132 having different configurations may be provided.
Then, by using the probability change determination table 132 depending on the lottery or according to a predetermined condition, even if the stop switch 50 is operated at the same step position, it is possible to form whether the probability change is different and the mode is different.

(Setting changing means 133) The setting changing means 133
This is for changing the setting of the slot machine 10 based on the step position information stored in the step position storage means 131. Specifically, when the step position when the stop switch 50 is operated belongs to the area of the probability change determination table 132 “setting change”, the slot machine 10
Setting change of, regardless of the current setting value by operating the device,
It is treated as if the settings were changed. Then, this is performed by changing the entire group of the winning determination table 113 provided for each set value shown in FIG. For example, even when the setting of the setting changing device of the slot machine 10 is set value 3, without using the winning determination table 113 provided corresponding to the set value 3 in the lottery Winning determination table 113 provided
Is to be used.

Then, this setting change can be performed as follows. (1) Change the current setting value to the one with a higher probability. The number of setting ranks to be increased may be predetermined as, for example, one rank, or may be set as x rank and the x value may be determined by lottery or by a predetermined condition.

When the current set value is the highest, the set value is not changed. (2) Change the current setting to the one with the lowest probability. The number of setting ranks to be lowered is the same as in (1) above. Also,
If the current set value is the lowest, the set value is not changed. (3) Whether to increase or decrease the probability of the current set value is determined by lottery.

The number of setting ranks to be raised or lowered may be the same as in (1) above, or may be randomly selected from the set values 1 to 6 by lottery. When the current rank is the lowest or the highest, the procedure may be similar to the above (1) and (2), or the set value may be determined by circulating the numbers 1 to 6. For example, if the current setting value is “6” and the result of the lottery is “2 rank up”, 6-1-2
It is like changing the setting value to 2.

By the way, the setting changed as described above is, for example, a predetermined number of times (1 to m
It is desirable that the game is formed so as to return to the original setting when the game of () is completed. The predetermined number of times may be set in advance or may be determined by lottery. (Winning determination table changing means 134) The winning determination table changing means 134 is for changing the winning determination table 113 used in the lottery related to winning in the same set value to another winning determination table 113 having a different winning probability. It is a thing.

That is, when the step position when the stop switch 50 is operated belongs to the area of the probability change judgment table 132 "change of win judgment table", the win judgment table 113 is changed. And this is
Winning determination table 11 shown in FIG. 6 provided for each set value
This is done by changing the winning determination table 113 in the group of 3.

The change of the winning determination table can be performed as follows. (1) Change to a high probability table. When the current high probability table is used, the winning determination table 113 is not changed. (2) Change to a low probability table.

When the current high probability table is used, the winning determination table 113 is not changed. (3) Change to a winning determination table with a high winning probability for a specific winning combination. For example, it is changed to the winning determination table 113 in which the area of "replay" is formed widely. In this case, if a lottery related to winning is performed using the winning determination table 113 for a predetermined game period, a so-called replay time game will be played.

(4) Winning determination table 113 corresponding to the inserted number
Is changed to the winning determination table 113 corresponding to another number of inserted coins. This is determined by a table for one sheet, a table for two sheets, a table for three sheets, or a lottery among them, regardless of the number of medals inserted in the game in which the winning determination table 113 is changed. It is to change the table.

For example, in the normal game, when three medals are thrown, if the winning determination table 113 for one shot is used, the winning probability is substantially lowered. On the other hand, if the winning determination table 113 for three coins is used when one medal is inserted, the winning probability is substantially increased. (5) Which winning determination table 113 is selected is determined by lottery.

By the way, the winning determination table 113 changed as described above is changed to the original winning determination table 113 when the game is performed a predetermined number of times (1 to m times) using the winning determination table 113, for example. It is desirable to form it back. The predetermined number of times may be set in advance,
It may be decided by lottery. (Operation of Slot Machine 10) Next, an outline of the operation of the slot machine having the above configuration will be described with reference to the flows shown in FIGS. 3 and 4. First, in step 100 shown in FIG. 3, the start switch 30 is turned on by operating the start switch 30. And
Proceed to next step 101.

In step 101, the winning lottery means 11
The lottery process is performed by 0. And next step 1
Go to 02. In step 102, the rotation of the rotary reel 40 starts. Then, the process proceeds to the next step 103.
In step 103, the stop switch 50 is turned on by operating the stop switch 50. Then, the process proceeds to the next step 104.

In step 104, rotation stop processing of the rotary reel 40 is performed. Then, the next step 105
Proceed to. In step 105, lottery probability change processing is performed. That is, the lottery probability changing means 130 determines whether or not the lottery probability has been changed and the mode based on the operation position of the stop switch 50 on the predetermined rotating reel 40. Then, the process proceeds to the next step 106.

In step 106, it is determined whether or not the stop switch 50 corresponding to the three rotating reels 40 has been operated. When it is determined that the stop switch 50 corresponding to the three rotating reels 40 has been operated, the process proceeds to the next step 107. In step 107, whether or not the winning symbols corresponding to the winning flag are aligned on the winning effective line while the winning flag is established, that is,
It is determined whether or not a prize has been won. Then, when it is determined that the prize has been won, the process proceeds to the next step 108.

At step 108, medals corresponding to the winning symbols are paid out. Then, the game ends.
If it is determined in step 106 that the stop switch 50 corresponding to the three rotating reels 40 is not operated, the process returns to step 103. Step 1
If it is determined in 07 that no prize has been won, step 108 is skipped and the game ends.

The lottery process in step 101 described above will be described with reference to the flow chart of FIG. In step 200, random numbers are extracted by the random number extraction unit 112 from the random numbers generated by the random number generation unit 111 of the winning lottery unit 110. Then, the process proceeds to the next step 201.

In step 201, the extracted random number is stored inside the random number extracting means 112. Then, the process proceeds to the next step 202. In step 202, the random number extracted by the determination means 114 and the winning determination table 1
Comparison with 13 winning determination area data is performed. And
Proceed to next step 203.

In step 203, the determination means 114 determines in which winning area of the winning determination table 113 the extracted random number is included, and determines the lottery process evaluation. Then, the process proceeds to the next step 204. In step 204, the stop table 121 corresponding to the evaluation is selected. That is, when the lottery result is a win, the stop table for the winning symbol is selected, and when it is lost, the stop table for the lose is selected. Then, the lottery process ends.

The rotation stop control means 120 acquires the determined stop table 121, and performs the rotation stop processing of the rotary reel 40 based on the stop table 121. (Other Embodiments Regarding Stop Control) By the way, the stop control is performed using a stop table.
The stop control can be performed without using the stop table. This is to perform control so that when any winning combination is won in the lottery, the symbols (winning symbols) corresponding to the winning are stopped at predetermined positions as much as possible, and the other symbols are not stopped.

Specifically, the bit corresponding to the winning symbol is provided separately for the winning symbol which should be stopped and the symbol which should not be stopped. Then, first, control is performed so as not to stop the symbols that should not be stopped, and then control is performed so as to stop the symbols that should be stopped.
These controls are performed based on the data stored in the above-mentioned bits.

In the case of this control method, in step 204 described in FIG. 4, kicking of a predetermined symbol and pulling in of a predetermined symbol are set. Then, the reel rotation stop processing of step 104 shown in FIG.
It becomes as shown in the flow of. In step 300,
It is determined whether or not the kick-off setting has been achieved for the predetermined symbol. When it is determined that the kicking-off setting of the predetermined symbol is not achieved, the next step 3
Go to 01.

In step 301, the rotary reel 40 is rotated by one symbol. That is, kicking is performed by one symbol. Then, the process proceeds to the next step 302. In step 302, it is determined whether or not the number of the symbols obtained by rotating the rotary reel 40 by one symbol described above corresponds to the fourth symbol after the operation of the stop switch 50. Then, after operating the stop switch 50, the number of symbols shifted by rotating the rotary reel 40 one by one is 4
In the case of the number th, it proceeds to the next step 303.

In step 303, the rotation of the rotary reel 40 is stopped. As a result, the operation of the slot machine 10 from the insertion of the medal to the stop of the rotation of the rotating reel 40 is completed. If it is determined in step 300 that the kicking-out of the predetermined symbol has been achieved, the process proceeds to the next step 304.

At step 304, it is judged whether or not the drawing is set for any of the symbols. Then, when it is determined that the drawing is set for any of the symbols, the process proceeds to the next step 305. At step 305, it is determined whether the retraction setting has been achieved. When it is determined that the pull-in setting has been achieved, the process proceeds to the next step 303.

In step 304, if it is determined that the drawing is not set for any of the symbols, the process proceeds to step 303. If it is determined in step 305 that the pull-in setting has not been achieved, the process proceeds to step 301. In step 302, when the stop switch 50 is operated and the number of symbols shifted by rotating the rotary reel 40 one symbol at a time is not the fourth symbol, the process returns to step 300.

In the above-described embodiment, the example described in steps 301 to 305 regarding the stop processing of the rotary reel 40 is an example of so-called minimum pull-in stop control, and conversely, the maximum pull-in stop control is also possible. Good. (Lottery Probability Changing Process by Lottery Probability Changing Unit 130) Next, the lottery probability changing process of step 104 in FIG. 3 will be described based on the flow of FIG. 7. In this embodiment, the presence / absence and the mode of probability change are determined based on the operation position of the stop switch 50 on the rotary reel 40 which is predetermined or determined by lottery.

First, in step 400 in FIG. 7, the rotating reel 40 whose stop switch 50 has been operated is
It is determined whether the reel is for the stop switch operation position measurement. If the reel is not related to the stop switch operation position measurement, the lottery probability changing process ends. on the other hand,
If the reel is for the stop switch operation position measurement, the process proceeds to the next step 401.

In step 401, the step position when the stop switch is operated is stored. That is, the step position storage means 131 inputs and stores the step position information of the rotary reel 40 measured by the step position measuring means 123 when the stop switch is operated. Then, the process proceeds to the next step 402. In step 402, comparison with the probability change determination table 132 is performed. That is, the determining means compares the step position stored in step 401 with the area related to the probability change.
Then, the process proceeds to the next step 403.

In step 403, it is determined in which area of the probability change determination table 132 the stored step position is included, and the evaluation of the probability change process is determined. Then, the process proceeds to the next step 404. In step 404, it is determined whether the lottery probability has changed as a result of the evaluation. Specifically, it is determined whether or not the setting of the slot machine 10 is changed and whether or not the winning determination table 113 is changed. If there is no change in the lottery probability, the next step 4
Go to 05.

At step 405, the setting relating to the lottery probability is returned to the initial setting. That is, the lottery probability changing means
The setting value of the slot machine 10 changed by 130 is returned to the original value, and the winning determination table 113 changed by the lottery probability changing means 130 is returned to the original winning determination table 113. In the previous game, when the setting value of the slot machine 10 or the winning determination table 113 is not changed by the lottery probability changing means 130, the setting value or the winning determination table 113 is not changed and remains as it is. Then, the lottery probability changing process ends.

When there is a change in the lottery probability in step 404, the process proceeds to step 406. Step 4
At 06, a predetermined lottery probability changing process is performed. That is, the settings of the slot machine 10 are changed, and the winning determination table 113 is changed. Then, the lottery probability changing process ends.

(Other Embodiments Regarding the Lottery Probability Changing Process) By the way, in the example shown in FIG. 7, it is determined whether or not the lottery probability changing process is performed for each game, but it is once changed. It is not specified when the lottery probability will be restored. Therefore, the once-selected lottery probability cannot be maintained for a predetermined period.

Therefore, for example, by the lottery probability changing process,
When starting a special game, for example, a replay time game, the control shown in the flow of FIG. 8 is performed. here,
In the figure, n is the number of games played after the lottery probability is changed, m
Represents the maximum number of possible executions (1 or more) of the game after the change. The measurement of the n value is performed by a game number measuring means (not shown) provided in the control device, and the m value may be predetermined according to the lottery probability changing mode, or the lottery probability. The changing means 130 may be provided with a game number determining means (not shown), and the game number determining means may determine the m value by a lottery or other predetermined method.

First, by operating the stop switch 50, the lottery probability changing means 130 starts its operation. Then, in step 500 in FIG. 8, the step position when the stop switch is operated is stored. In this case, the step position corresponding to one of the rotating reels 40 that is predetermined or determined by lottery may be stored, or the step when the stop switch corresponding to the plurality of rotating reels 40 is operated. An average value of the numbers may be stored as the step position. Then, the process proceeds to the next step 501.

In step 501, the probability change judgment table 132 is compared. And the next step 50
Go to 2. In step 502, which region of the probability change determination table 132 the stored step position is included in is determined, and the evaluation of the probability change process is determined. Then, the process proceeds to the next step 503.

At step 503, as a result of the evaluation, it is judged whether or not the lottery probability is changed. If there is a change in the lottery probability, the process proceeds to the next step 504. In step 504, a winning probability changing process is performed. At the same time, the m value is determined and the n value is cleared to zero. Then, the process proceeds to the next step 505. In step 505, it is determined whether n = m. If not n = m, the process proceeds to the next step 506.

At step 506, n = n + 1 is performed. That is, the game number measuring means counts the number of games triggered by the insertion of a medal, the pressing of the bet switch 16 or the reception of a signal for pressing the start switch 30. Then, the process returns to step 505. When it is determined in step 503 that the evaluation result indicates that the lottery probability has not changed, and when n = m in step 505, the process proceeds to step 507.

At step 507, the setting relating to the lottery probability is returned to the initial setting. If the determination in step 503 is that the lottery probability is not changed, the current state remains. Then, the lottery probability changing process ends. Thus, according to this embodiment, the stop switch 50 is used instead of the stop symbol.
Since the lottery probability is changed based on the operation position of
It is difficult for the player to determine when the probability is changed, and it is possible to give a surprising effect to the game. Furthermore, by providing a predetermined reference point display unit 140 on the rotating reel 40, it is possible to create a new game property in which the timing of pressing is searched for a point where the lottery probability is changed. .

By the way, although the present embodiment is configured as described above, this slot machine is
The gaming machine, a symbol display means for displaying a plurality of symbols in a variable display or a stop display, a symbol variation start means for starting a variable display of the symbols, a symbol variation stop for displaying a variation displayed symbol in a stopped manner. Means, winning lottery means for performing a lottery of a winning combination with a predetermined probability, winning means for treating as a prize on condition that the plurality of symbols are displayed in a predetermined mode, operation of the symbol variation stopping means Position measuring means for recognizing the position on the symbol display means at the time, and function as lottery probability changing means for changing the lottery probability of the lottery of the winning combination based on the position measured by the position measuring means.
