Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine used in a game arcade such as a pachinko parlor, a game machine program, and a recording medium on which the game machine program is recorded.

[0002]

2. Description of the Related Art A slot machine installed and used in a game hall such as a pachinko parlor is called a pachislot machine, and a medal serving as a game (game) medium is given a certain value, and a game is played. The obtained medals can be exchanged for various prizes. In this slot machine, the reel is driven by a stepping motor,
Whether or not to win by electronic lottery based on sampling of random numbers, or in the case of winning, the type of winning combination is determined, and reel stop control is performed according to this determination.
In the slot machine, a stop button is provided for each reel, and the stop control of the reel is started by a player operating the button, but as described above, it is easy to make a loss or a winning combination electronically drawn. The reel is controlled to stop.

[0003] In order to enhance the game characteristics of such a slot machine, a winning prize is determined to be a small prize for paying out a certain number of medals, and also to a bonus prize which gives a right to shift to a bonus game. I have. When the winning prize is electronically drawn, the reels are stopped and the prize winning is obtained, the game shifts to the bonus mode, the game is started, and until a certain number of games or a certain number of prizes are obtained. Wins can be obtained with a higher probability than in the game under the normal mode (regular bonus game). It should be noted that there is a continuous role winning combination among the role winning combinations, and when this is obtained, a bonus game including the bonus mode (regular bonus game) two to three times can be performed (big bonus game). .

[0004] Furthermore, some recent slot machines include:
In some cases, after a continuous role winning combination is determined and the game in the bonus mode associated therewith ends, the mode shifts to a challenge time (CT) mode. In the game under the CT mode, the reel stop control is performed as usual for the bonus prize combination and the replay (replay) that can be shifted to the bonus mode. Although a winning combination does not appear, the reel stop control is in a free state for a small hit that is not related to the bonus game, and the reel stop is performed completely based on the player's stop operation. For this reason, even if the loss is performed by electronic lottery, a small hit can be obtained if the operation timing of the stop button is appropriate. Therefore, for a skilled person who can perform so-called eyes, this C
Small hits can be obtained continuously during the T mode, which provides a chance to obtain a larger number of medals than in the normal mode.

In the CT mode, in addition to the occasion of winning a special prize, when the number of games reaches a specified number (for example, 150), or when the net number of medals in the CT mode is increased to a specified number (for example, 200). Is decided to end when the number of pieces reaches). When a winning prize is obtained, the game shifts to a bonus game so that anyone can easily win the prize. There is no problem if the CT mode is terminated at that point, but the number of games in the CT mode or the net increase By simply setting the upper limit as described above, there is an extreme gap in the number of medals to be acquired between a skilled person who can push and an unskilled person. Then, while a skilled person can acquire almost the number of medals close to the upper limit, an unskilled person may lose almost all the medals acquired so far even during the CT mode.

[0006]

If the upper limit of the number of games and the net increase in the CT mode is reduced to improve such a situation, the pleasure of the skilled person will be reduced. For this reason, while these upper limits are maintained at the previous values, for example, C is set for each game after entering the CT mode.
There is a method of randomly selecting whether or not to continue the T mode and stochastically leaving the possibility of continuing the CT mode up to the upper limit. However, if the CT mode is terminated only by the result of the lottery, it cannot be said that the skilled person has a great sense of expectation and tension for continuing the CT mode.
There is little interest in it.

The present invention has been made in consideration of the above background, and it is possible that a large number of medals may be obtained by playing a game in the CT mode while adopting a configuration in which the CT mode is terminated by lottery. It is an object of the present invention to provide a gaming machine capable of giving a sense of expectation and a sense of tension, a program for the gaming machine, and a recording medium on which the program for the gaming machine is recorded.

[0008]

In order to achieve the above object, a gaming machine of the present invention comprises: a winning combination determining means for determining a winning combination by a lottery every time a game is started; and a stop operation provided for each reel. And reel stop control means for controlling the stopping of the reel being rotated so as to correspond to the winning combination determined by the winning combination determination unit when the means is operated, and after a specific condition is satisfied, the player Profit provision probability to the game in the special game mode different from the game in the normal mode is to be performed, at least counting the number of games or the number of net increase medal in the special game mode,
Counting means for terminating the game in the special game mode when at least one of the number of games or the number of purely increased medals reaches a preset upper limit value, and a probability table according to a game state in the special game mode And a counter initialization judging means for deciding whether or not to initialize the count value of the number of games or the number of purely increased medals by the counting means based on the lottery result. Note that the gaming state includes the number of games, the number of net increase medals, the winning combination, the winning combination, the game time, and the like. In addition, the reason that the probability of providing a profit to a player is different from that in the normal mode is that, for example, the probability of a winning combination being drawn by the winning combination determining means is higher or lower than that of the game in the normal mode. Or fluctuate.

[0009] Further, it is preferable that a game in the special game mode has a higher probability of giving a profit to a player than a game in the normal mode. Here, the higher the probability of providing a profit to the player than the game in the normal mode means that, for example, in the winning combination determination unit, the probability that the winning combination is drawn is higher than that in the normal mode. Or if
This includes increasing the frequency of notifying the player that the winning combination has been determined (internal winning state). In the game in the special game mode, the reel stop control by the reel stop control unit is suppressed,
It is preferable that the stop timing of the reel is controlled by giving priority to the operation timing of the stop operation means.

Further, the probability table is selected from a plurality of probability tables having different lottery probabilities such that the lottery probability for initializing the count value of the counting unit according to the number of games in the special game mode is increased. If the number of games exceeds a predetermined number,
Preferably, a probability table with the highest lottery probability for initializing the count value of the counting unit is selected from the plurality of probability tables.

The special condition is that the special prize winning combination is decided by the prize combination deciding means, and the special game prize deciding means for deciding whether or not to enter the special game mode is determined by the special game prize deciding means. When it is determined to make a rush, after the bonus prize symbols are aligned on the prize line and the bonus prize combination is determined, the game in the bonus mode in which it is easier to obtain a prize than in the normal mode has ended. It is preferable to be established at the time. In addition, the specific condition, when the bonus prize combination with the entry condition to the special game mode is determined by the prize combination determination means, and after the bonus prize combination is determined, than in the normal mode It is preferable that the game is established when the game in the accessory mode in which a winning is easily obtained ends.

The program may include a means for determining a winning combination at the start of the game, a means for controlling the stopping of the rotating reel so that the winning combination determined when the stop operating means is operated, Means for shifting to the special game mode in which the profit provision probability to the player is different from the game in the normal mode after the condition is satisfied, and means for determining whether or not the character winning combination performs the special game mode. Besides, means for counting until at least the number of games or the number of net increase medals in the special game mode reaches the upper limit, means for performing a lottery according to the number of games in the special game mode, the number of games or The computer functions as means for initializing the count value of the number of net increased medals.

As the storage medium, means for determining a winning combination at the start of the game, means for controlling stop of the rotating reel so that the winning combination determined when the stop operating means is operated, Means for shifting to a special game mode in which the profit provision probability to the player is different from the game in the normal mode after a specific condition is satisfied, and it is determined whether or not the character winning combination performs the special game mode. In addition to the means, means for counting until at least the number of games or the number of net-added medals in the special game mode reaches an upper limit, means for performing a lottery in accordance with the number of games in the special game mode, Alternatively, a program for a gaming machine for causing a computer to function as a means for initializing the count value of the number of net increased medals is recorded.

[0014]

FIG. 1 shows the appearance of a slot machine using the present invention. Four design display windows 4 are provided on a front door 3 of the housing 2, and a first reel 5 is provided behind each of the display windows 4.
a, a second reel 5b, a third reel 5c, and a sub reel 6 are rotatably incorporated. As is well known, the first
Various symbols are arranged at a constant pitch on the outer periphery of the third to fifth reels 5a to 5c, and three symbols per reel are observed through the symbol display window 4 when the reels are stopped. As a result, a total of five straight winning lines, two diagonal lines and three diagonal winning lines, each of which is composed of one symbol on each reel, are set.

When one medal is inserted from the medal insertion slot 7 prior to the start of the game, one pay line in the center is activated, three for two, and two diagonal for three. , The five pay lines are activated. It should be noted that four symbols per reel can be observed from the symbol display window 4, and in addition to the four horizontal prize lines, another prize line bent so as to combine one symbol for each reel. Can also be set.

When the start lever 8 for starting a game is operated, the sub reel 6 at the right end holds the other reels 5a to 5a.
Start rotation with c, and in the subsequent electronic lottery, for example, BB
The stop control is performed at the position where the symbol “7” is displayed when the BB shift combination to be shifted to the mode is selected by lottery. The transition to the BB mode is performed when the combination of the symbols on the first to third reels becomes “7-7-7”, but when the BB flag is randomly selected, the combination of “7-7-7” Is easy to obtain. Therefore, when the symbol "7" is displayed by the sub reel 6, the player has a great expectation and feels that the stop button 9 for each reel is
By operating a, 9b and 9c, the effect of producing a slot machine game can be enhanced.

On the operation panel above the stop buttons 9a to 9c, various operation buttons such as a single bet button, a MAX bet button, and a settlement button operated when playing a game with medals stored (credit) are provided. Is provided. Since the functions of these operation buttons are all well known, the details are omitted. Also, housing 2
A medal tray 10 is provided at a lower part of the payout medal to receive a payout medal paid out from the payout opening 11 when a win is obtained in the game.

FIG. 2 schematically shows the electrical configuration of the slot machine. The operation of the slot machine is basically CPU1
5 and a memory 16 which is controlled by a microcomputer. The medal sensor 17 detects a proper medal inserted from the medal insertion slot 7 and inputs the detected medal to the CPU 15. A selector is installed in the back of the medal insertion slot 7, and inappropriate medals are discharged to the tray 10. In addition, when a medal is inserted at inappropriate timing, for example, a medal inserted in the middle of a game or in a state where various operation buttons are kept pressed, the selector does not pass through the medal sensor 17. Discharge to the pan 10.

The CPU 15 determines the number of one to three medals inserted before the start of one game by the medal sensor 17.
Counting based on the detection signal from the CPU, thereby determining the number of activated pay lines. The bet number of medals inserted every time the game is started is integrated and counted by the inserted medal counter 18. The number of credits is counted by another credit medal counter (not shown).

The start signal generator 19 inputs a game start signal to the control unit 32 of the CPU 15 when the start lever 8 is operated after one to three medals have been inserted. Each time a game start signal is input, the count value of the game number counter 20 is incremented by “1”. Therefore, the number of games executed in this slot machine can be identified by referring to the count value of the game number counter 20.

Upon receiving the game start signal, the CPU 15
Starts the game processing while rotating the first to third reels 5a to 5c and the sub reel 6 based on the game execution program stored in the ROM area of the memory 16. The reel drive controller 23 constitutes a part of a reel stop control unit, and the reel drive controller 23 controls the drive and stop of each reel. Each of the reels is fixed to a drive shaft of an individual one of the stepping motors 24a to 24d.
By controlling the drive of d, each reel is controlled. The RAM area of the memory 16 is a working area, and is used for temporary storage and rewriting of flags and data used for each game.

Since the stepping motors 24a to 24d rotate at a rotation angle corresponding to the number of supplied drive pulses, the CPU 15 controls the number of supplied drive pulses to control the first to third reels 5a to 5c and the sub reels. 6 can be controlled, and the stop position of the reel can be determined by cutting off the supply of the drive pulse. In addition, each reel is integrally formed with reflection signal portions 25a to 25d at its reference position, and the photo sensors 26a to 26d photoelectrically detect the passage of each reflection signal portion for each rotation. The detection signals from the photosensors 26a to 26d are input to the CPU 15 from the reset signal generator 27 as a reset signal for each reel.

A pulse counter for each stepping motor is provided inside the CPU 15 and counts the number of driving pulses supplied to each stepping motor. Then, when the reset signal is input from the reset signal generator 27, the count value of the corresponding pulse counter is cleared. Therefore, in each pulse counter, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is stored while being sequentially updated.

A symbol table is stored in the ROM area of the memory 16. This symbol table stores one table data in which the number of drive pulses corresponding to the rotation angle of each reel from the reference position is associated with a symbol code representing each symbol arranged on the reel at a constant pitch. Have been. Therefore, by monitoring the count value of the pulse counter for each reel, it is possible to identify, for example, which symbol is moving on the central winning line, and if the reel is further rotated, Can be predicted if the symbol moves on the winning line.

The stop signal generator 28 inputs a stop signal for each reel to the CPU 15 when the stop buttons 9a to 9c are operated. By operating the start lever 8, the rotation of all the reels starts, and these rotations are about 80R.
Stop button 9a when a steady speed of about PM is reached
9c are activated. Thereafter, by operating these, the corresponding first to third reels 5a are respectively provided.
5c is started, and after the stop button is operated, the corresponding reel is stopped within 190 msec.

When the game results in a hit, a specified number of payout medals are received by the medal hopper 29 in the receiving tray 1.
Pay out to 0 or add the specified number to the credit counter. A payout table in which the number of payout medals is determined for each type of winning is stored in the ROM area of the memory 16, and the CPU 15 reads this and reads the medal hopper 2
9 is driven.

The initial setting input unit 30 is provided inside the housing 2 together with the power switch, and can be operated with the front door 3 opened. When the operator at the game hall opens the front door 3 and turns on the power switch for the operation of the slot machine, the initial setting input unit 30 is appropriately operated to allow the slot machine to operate in the BB mode or the CT mode, for example. Initial settings such as whether or not to stop the game at the end of the game and at the same time whether or not to perform automatic settlement of credited medals can be made. The payout rate can be changed in six stages by a dip switch or the like, and the payout rate of the slot machine can be changed every day depending on which one is selected.
The payout rate can be easily changed by adjusting the allocation of the winning symbols in the winning table.

The CPU 15 includes a control unit 32, an electronic lottery unit 33, a winning combination determination unit 34, a special game winning determination unit 35, C
A T-mode initialization lottery unit 36 is provided. Control unit 3
No. 2 controls the game control. This control unit 32
Constitutes a reel stop control means together with the reel drive controller 23. When the stop signal is output from the stop signal generator 21, the ROM of the memory 16 is controlled based on the winning combination signal from the winning combination determination unit 34. A symbol table stored in the area, and photo sensors 26a to 26
A symbol to be stopped in each display window is selected from the detection signal from c, and each reel is stopped. The winning combination determination unit 34
Special game winning determination unit 35 based on the winning combination signal from
It is determined whether or not the winning signal from is valid.

The electronic lottery section 33 includes a random number generator and a random value sampling circuit. Each time a game is started, one random number is drawn, and the value is determined as a winning combination determining section 34 and a special winning combination determining section. 35. The winning combination determination unit 34 is provided with two winning tables in which random numbers are grouped according to their sizes. The bonus game in this slot machine includes a single bonus game (SB) in which one bonus game is given when a specific symbol is aligned on a winning line, and a regular bonus game (RB) that is a so-called continuous bonus. ), Big Bonus Game (BB) including regular bonus game two or three times
Etc. In the first winning table, the random value sampled during the game in the normal mode is a big bonus (B
B) A BB transfer role (continuous prize winning combination) that gives the right to shift to the mode, an RB transfer role (government prize winning combination) that gives the right to shift to the regular bonus (RB) mode, and only a predetermined number of medal payouts Is used to determine whether the game belongs to one of a small role winning and a loss that does not generate any hits.

The second prize table is used during the bonus game period, and is used to select whether to win or lose in a game played in the BB mode or the RB mode. In the second winning table, random numbers are grouped so as to increase the probability of winning, so that winning is easier to obtain than in the game in the normal mode.

The special game winning determination section 35 is provided with a winning table in which random numbers are divided into two groups according to their sizes. Using this winning table, it is determined whether or not the random number value output from the electronic lottery device 33 performs the CT mode. Then, the determination result is transmitted to the control unit 32.
Output to

For example, the winning combination determined by the winning combination determination unit 34 is a BB transfer combination, and the special game winning determination unit 35 selects C
When it is determined that the T mode is to be performed, if the player arranges the symbol combinations corresponding to the BB transition winning combination, which is a continuous character winning combination, on the same activated winning line, first the game in the BB mode Is performed. When the game in the BB mode is completed, a specific condition is satisfied, and the game enters the CT mode. In the game in the CT mode, the stop control by the stop signal generator 21 is suppressed, and the stop button 9
The stop control of each reel is performed by giving priority to the operation timings a to 9c. For example, the symbol combination "7"-"7"-
When "7" is determined, the stop buttons 9a to 9
The stop control by the stop signal generator 21 is performed from the operation timing of c.

On the other hand, if the winning combination determination unit 34 is not a BB transfer combination, the stop control of each reel is uncontrolled within a range where the symbol "7" is not aligned on the same activated winning line, Reel stop control is performed with priority given to the operation timing of the stop buttons 9a to 9c. That is, the control unit 32 receives the stop signal from the stop signal generator 21 and uses the symbol table and the detection signals from the photosensors 26a to 26c to control each reel so that the symbol "7" is not aligned on the winning line. To stop. Thereby, if the pressing timing of the stop buttons 9a to 9c is appropriate,
You can get a small role. For this reason, when the game in the BB mode and the game in the CT mode are performed, the medal acquisition amount obtained by the player increases. In the game under the CT mode, the net number of medals is, for example, 100 or more, or the number of games in the CT mode is, for example, three.
The process ends when the number of times exceeds zero. Also, when the symbol combination "7"-"7"-"7" is determined in the game in the CT mode, the game in the CT mode ends, and the game enters the BB mode.

In the game in the CT mode, the CT mode initialization lottery section 36 is used. As shown in FIG.
The CT mode initialization lottery unit 36 includes a determination unit 37 and a count unit 38. The determination unit 37 determines whether the electronic lottery device 4
0, a result determination unit 41, and a probability table 42. The electronic lottery device 40 has a random number generator and a sampling circuit, samples a random number at the start of the game in the CT mode, and outputs the result to the result determination unit 41. The result determination unit 41 uses the probability table 42 to determine whether to initialize the number of games played in the CT mode and the number of net increase medals.

In the probability table 42, a group for terminating the CT mode, a group for initializing the number of digested games and the number of net-added medals in the CT mode, and a group for out of the group are formed. By using this probability table, whether to end the CT mode is determined at the same time. Note that the initialization lottery by the CT mode initialization lottery unit 36 may be performed every predetermined number of times (for example, twice). Also, if you win the initialization lottery, CT
Instead of initializing both the number of games and the number of net-added medals in the mode, one of the number of games and the number of net-added medals may be initialized.

The counting section 38 includes a game number counting section 4.
5, a medal counting section 46, a count determining section 47, and a reset signal generating section 48. The game number counting section 45 counts the number of games in the CT mode, and the medal counting section 46 counts the number of net increased medals in the CT mode. In the count determination unit 47, a set value that is the upper limit of the number of games in the CT mode and the number of net-added medals in advance (for example, the number of games 30 and the number of net-added medals 100)
Is stored. By comparing these set values with the count numbers in the game number counting section 46 and the medal counting section 47, it is determined whether or not to end the game in the CT mode, and the result is output to the control section 32.

The count determining section 47 outputs the number of remaining games in the CT mode to the control section 32, and displays the number of remaining games on the number-of-games display 50 based on the output. The reset signal generation unit 48 is configured to output the game number counting unit 45 and the medal counting unit 46 when the determination unit 37 outputs the initialization signal and the end signal, or when the count determination unit 47 outputs the end signal.
Is provided to initialize the count number of.

The operation of the above slot machine is shown in FIG.
This will be described with reference to the flowchart of FIG. When the user operates the start lever 8 after inserting one to three medals prior to the start of the game, the game in the normal mode is started, and the first to third reels 5a to 5c and the sub reel 6 rotate simultaneously. Start. At the same time, the electronic lottery device 33 samples random numbers and outputs them to the winning combination determination unit 34 and the special game winning determination unit 35. Using the random number value, the winning combination determination unit 34 determines a winning combination, and the special game winning determination unit 35 determines the presence or absence of the CT mode, and outputs each winning signal to the control unit 32. For example, when a winning combination other than the BB transfer combination is determined by the winning combination determination unit 34, the control unit 32 invalidates the special game winning signal from the special game winning determination unit 35.

On the other hand, when the winning combination determination unit 34 becomes the BB transfer combination, the winning combination signal is fed back to the control unit 32 and the BB flag is written in the RAM area of the memory 16. Further, the control unit 32 validates the special game winning signal from the special game winning determining unit 35. For example, if the special game winning signal is for performing the CT mode, the control unit 32
Writes a CT flag in the RAM area of the memory 16. B
When the B flag is set, the CPU 15 starts stop control of the stepping motor 28d driving the sub reel 6,
The sub reel 6 stops with the symbol “7” displayed on the display window 4. As a result, the player can know that the symbol combination "7"-"7"-"7" serving as the BB transfer combination is in a state in which it is easy to appear, and can start playing the game with great expectation. Then, the CPU 15 refers to the count value of the above-described pulse counter provided for each reel from the operation timing of the stop buttons 9a to 9c and makes the stepping motors 28a to 28
The stop control of c is performed.

When the first to third reels 5a to 5c are stopped and the symbol combination "7"-"7"-"7" is completed, payout medals are paid out, and the game shifts to a game in the BB mode.
In the game in the BB mode, the winning table used in the electronic lottery device is switched to the second winning table. Then, after inserting one to three medals, the game is started by operating the start lever 8 in the same manner. If the second prize table is used, the winning is determined with a high probability,
When the stop buttons 9a to 9c are operated to stop three reels, the same symbols are often aligned on the activated pay line, and the number of payout medals according to the symbol combination can be obtained. .

When the game in the BB mode ends, C
The control unit 32 of the PU 15 stores the CT in the RAM area of the memory 16.
Check for the presence of the flag. When the CT flag is confirmed, the control unit 32 shifts the game mode to the CT mode. When the game is performed in the CT mode, the electronic lottery is also performed. For example, when the winning combination determined by the winning combination determination unit 34 becomes the BB transfer combination that shifts to the BB mode, the normal reel stoppage is performed. Control is performed. That is, when the stop buttons 9a to 9c are operated, a stop signal is output from the stop signal generator 19 to the control unit 32. The control unit 32 uses the symbol table from the ROM of the memory 16 and the detection signals from the photosensors 26a to 26c to display the symbol combinations "7"-"7"-"7" on the same winning line where the symbol combinations are validated. Align. In this case, the CT mode ends, and the next game is a game in the BB mode.

On the other hand, in the case of a loss or a small role in the winning determination section 34, the stop buttons 9a to 9c are operated to
Each reel is stopped in a state close to the operation timing of the stop button so that the symbol "7" does not form the same winning line. Even if the losing is determined by the winning determination unit 34, the symbol "7" does not stop so as to be aligned on the same winning line, but the symbol corresponding to the small role cannot be aligned on the same winning line. it can.

In the CT mode, the control unit 32 operates the CT mode initialization lottery unit 3 together with the operation of the start lever 8.
Then, a game start signal is output to 6. Game number counting section 4
At the same time when the number of games is counted at 5, the determination unit 3
At 7, sampling of random numbers using the electronic lottery device 40 is performed. In the result determination unit 41, the random number value sampled by the electronic lottery device 40 and a probability table (for example, the lottery probability 1 /
60) and 42, it is determined whether or not to initialize the number of games and the number of net-added medals.

For example, in the game in the CT mode, when the result determination unit 41 determines that initialization is to be performed,
The control unit 32 resets the counts of the game number counting unit 45 and the medal counting unit 46 via the reset signal generation unit 48 when the game is completed. Thereby, the number of remaining games on the game number display 50 is switched from 30-n (n: the number of digestive games) to 30. On the other hand, in the game in the CT mode, the count value of the game number counting unit 45 is determined to be, for example, 30 or more, or the count value of the medal
If it is determined that the value is not less than 00, an end signal is output to the control unit 32. Upon receiving the end signal from the count determining unit 47, the control unit 32 ends the CT mode and shifts to the normal mode. Similarly, when the result determination unit 41 determines that the CT mode is to be ended, the control unit 32 ends the CT mode and shifts to the normal mode. As a result, when the initialization is performed, the number of games and the number of net increase medals are respectively reset, so that a chance of obtaining a large number of medals is increased by winning the initialization lottery. It can give you a sense of tension and expectation.

A program for executing the procedures and functions shown in the flowcharts of FIGS. 3 to 5 by the controller of the slot machine may be stored in a recording medium such as a CD-ROM, a floppy disk, and a DVD. For example, as shown in FIG. 6, the recording medium 55 has a function of performing an initial lottery in the CT mode, a function of determining the lottery result using a probability table, a function of counting the number of games in the CT mode, A program for realizing a function of counting the number of net-added medals in the mode, and a function of initializing the counted number of games and the number of net-added medals is stored. This storage medium 55 is transferred to the slot machine 5
6, the program is installed in a slot machine, or the program is executed with a storage medium loaded in the reading device. Further, by storing a plurality of probability tables having different probabilities in the storage medium 55,
The probability table may be selected from a plurality of probability tables so as to increase the lottery probability in accordance with the number of games, and if the number of games exceeds a set value, the probability table having the highest midline probability may be selected. . Note that reference numeral 58 denotes CP

In this embodiment, the number of games in the CT mode and the number of obtained medals are initialized by using a probability table of a predetermined lottery probability. However, one of a plurality of probability tables having different lottery probabilities is initialized. May be selected. In this case, probability tables having different lottery probabilities (for example, the probability of being initialized is 1/30, 1/2
(0, 1/10 probability table), and the result is determined by selecting the lottery probability in accordance with the number of games. For example, if the number of games is one, the lottery probability is 1/3
Select the probability table of 0, the probability table of 1/20 for the second time, the probability table of 1/10 for the third time,
An initialization lottery is determined. In the case where the lottery probability is changed according to the number of games, a probability table having a low lottery probability according to the number of games may be used in addition to increasing the lottery probability according to the number of games as described above.
When a plurality of probability tables are provided, a probability table to be used may be selected according to a game state such as the number of games, a winning combination, and a game time.

In the present embodiment, the special game winning determination unit 35
Is used to determine the presence or absence of the CT mode. However, the presence / absence of the CT mode may be determined by the winning combination determination unit 34 without using the special game winning determination unit 35. In this case, in the winning table of the winning combination determining unit 34, a group serving as a BB transferring role with CT and a group serving as a BB transferring role without CT are provided in advance. Thereby, the winning combination determination unit 34 determines the winning combination using the random number value from the electronic lottery device 33, and at the same time, when the winning combination becomes the BB transition combination, simultaneously determines the presence or absence of the CT mode.
