Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine installed and used in a game hall such as a pachinko parlor.

[0002]

2. Description of the Related Art In the present specification, a pachi-slot machine is used as an example for explanation. Therefore, a medal is used as a game medium, but the game medium includes other media such as coins and pachinko balls. In addition, in "insert medal (game medium)",
In addition to actually inserting a medal into the medal insertion slot, betting a credited medal with a bet button or the like is included. Further, a state in which the winning symbols are arranged on the winning effective line is a prize, and a state in which a winning combination is drawn by electronic lottery before the winning is an internal prize.

A slot machine installed and used in a game hall such as a pachinko parlor is called a pachi-slot machine, and a medal, which is a game medium, is given a certain value to win a medal obtained by playing a game. It can be exchanged for various prizes. Therefore, the player generally attempts to play the game by only selecting a platform that is easy to obtain the right to shift to the bonus game mode for the purpose of obtaining a large number of medals. The bonus game modes include, for example, a big bonus (BB) mode and a regular bonus (RB) mode. In particular, the BB mode is changed to the RB mode a predetermined number of times, and before the transition to the RB mode, a small role is played. Since the mode is shifted to the RB introduction mode in which the winning probability of is increased, a large number of medals can be acquired in a short period of time.

The expectation that a large number of medals can be won in a short period of time is an important factor in attracting a player to a slot machine, and in addition to the bonus game mode, a special mode that can expect a large number of medals to be obtained. There is a tendency to provide a large number of models that are variously devised in order to encourage the player's euphoria. As one of the special modes, an assist time (AT) for informing the reel stop operation mode so as to increase the profit-probability of the player.
The mode is known. In the AT mode, for example, a sub reel provided separately from the three reels, a liquid crystal panel, voice, or the like is used to notify the player of the color of the design to be stopped on the winning line and the operation sequence of the stop button. If the player operates the stop button in accordance with this notification, it becomes easy to win the small winning combination having the internal winning, so that the profit acquisition probability is increased.

The special mode includes other game modes such as a challenge time (CT) mode, a replay time (RT) mode and an assist replay time (ART) mode in addition to the AT mode. What is CT mode?
This is a game mode in which the reel stop control by the reel stop control means is suppressed, and the reel stop control is performed by giving priority to the operation timing of the stop button operation. The RT mode is one of the winning combinations, and the probability of winning the replay that allows the player to play the next game without inserting medals is higher than that of the normal mode in a predetermined number of games, and the player wins the medal. It is a game mode in which the game can be played while suppressing the consumption of.
In the game in the RT mode, the winning combination determination table used by the winning combination determining means is provided separately from the winning combination determining table for the normal mode and set so that the replay winning probability is higher than that in the normal mode. The winning combination is determined by switching to the RT mode winning combination determination table. The ART mode is a game mode in which the functions of the AT mode and the RT mode are fused, and the winning probability of the replay is higher than that of the normal mode in a predetermined number of games, and when a small win is won, This is a game mode in which the player is informed of the color of the winning design to be stopped on the winning effective line, the operation sequence of the stop button, and the like.

Some models provided with the AT mode are switched to the AT mode after the BB mode is completed, or are switched to the AT mode when the transfer lottery is won.
The trigger for starting the mode varies depending on the model. In the case where the transfer lottery is performed, for example, first, a lottery is performed as to whether or not the right to shift to the AT mode is given, and if the lottery is won, the number of times to shift to the AT mode is simultaneously determined. When the right to shift to the AT mode is given, a shift lottery to shift to the AT mode is performed in the game to be continued. In addition, when the right to shift to the AT mode is given plural times, the shift lottery is performed again in the game after the end of the AT mode. The winning probability of the transfer lottery is set high so that the player can switch to the AT mode only after playing a few games. If the right to switch to the AT mode is obtained multiple times, the player can repeatedly switch to the AT mode within a short period of time. And a large number of medals are won.

[0007]

However, in the above slot machine, since the winning probability of the lottery for shifting to the AT mode is set to be constant, it is possible to repeatedly shift to the AT mode within a short period of time. If the probability is set to be high, there is a problem that the player will be aware that when the game has been transferred to the AT mode for the number of times that the right has been obtained, and the player has played the game to some extent, the right to switch to the AT mode has been exhausted. there were. This not only reduces the player's expectations for the game, but also causes the slot machine's operating rate to decline due to the opportunity to end the game. In order to prevent this, it is conceivable to set the winning probability of the transfer lottery to a low value.
Since the number of games played between modes increases, the games may be delayed and lack of tension.

In order to solve the above problems, the present invention is a game played between special modes when it is decided to shift to a special mode in which the player's reel stop operation mode is informed plural times. It is an object of the present invention to provide a game machine, a program, and a recording medium capable of giving a sense of tension to a player.

[0009]

In order to achieve the above object, the gaming machine of the present invention comprises a winning combination determining means for determining one of a loss and a plurality of types of winning combinations by lottery.
In the game in the normal mode and the special mode, in the game in the special mode, in the gaming machine in which it is easy to obtain the privilege in the game for the predetermined number of game periods, the loser selected by the winning combination determination means is selected. Or, depending on the type of winning combination, whether or not to grant the right to shift to the special mode is determined by lottery, and when it is decided to grant the right to shift to the special mode, the number of transitions is determined by lottery. After the special mode shift number lottery means and the right to shift to the special mode are given by the special mode shift number lottery means, one of a plurality of special mode shift probability tables having different shift probabilities to the special mode is selected. Select a lottery and shift from normal mode to special mode in response to winning in this lottery Special mode transition And the number of transitions to the special mode until the number of transitions determined by the special mode transition number lottery means is reached, and one preset according to the count value is set to the plurality of special mode transition probability tables. It is provided with a special mode transition probability table switching unit that is selected from among the special mode transition units and used for the lottery in the special mode transition unit.

As the special mode, it is effective to provide an AT mode, a CT mode, an RT mode, an ART mode, etc. in order to make the game more interesting. The AT mode is a game mode in which the player is informed of the color of the winning pattern to be stopped on the winning line and the operation sequence of the stop button when a small winning combination is won in a predetermined number of games.

The CT mode is a game mode in which the reel stop control by the reel stop control means is suppressed and the reel stop control is performed by giving priority to the operation timing of the stop button operation.

The RT mode is one of the winning combinations, and the probability of winning the replay that allows the next game to be played without inserting medals is higher than that of the normal mode in a predetermined number of games, and the game is played. This is a game mode in which a player can play a game while suppressing the consumption of medals.
In the game in the RT mode, the winning combination determination table used by the winning combination determining means is provided separately from the winning combination determining table for the normal mode and set so that the replay winning probability is higher than that in the normal mode. The winning combination is determined by switching to the RT mode winning combination determination table.

The ART mode is a game mode in which the functions of the AT mode and the RT mode are fused, and the winning probability of the replay is higher than that of the normal mode in a predetermined number of games, and the small win is won. In this case, it is a game mode in which the player is informed of the color of the winning pattern to be stopped on the winning line and the operation sequence of the stop button.

When the number of transitions to the special mode reaches a predetermined number, the special mode transition probability table used in the lottery by the special mode transition means is selected from a plurality of special mode transition probability tables. It is preferable to provide a special mode transition probability table determination means that is determined by lottery. As a result, for example, when a special mode transition probability table with a low transition probability is drawn, it becomes impossible for the player to detect even if a game is played a small number of times whether or not the special mode is transitioned. It is possible to give more tension to the game.

Further, when a transition number determination table which is used in the lottery by the special mode transition number lottery means and stores a plurality of types of transitions to the special mode is provided, the special mode transition probability table switching means, If the number of transitions to the special mode until the next special mode is one of a plurality of types of transitions preset in the transition number determination table, the special mode until the next special mode is set. It is preferable to select the special mode transition probability table having a higher transition probability than in the case where the number of transitions is not one of a plurality of types of transitions preset in the transition number determination table. This allows
If the number of transitions to the special mode until the next special mode is one of the preset number of transitions, the game will be delayed because the transition to the special mode is performed with a small number of games. Can be prevented.

Further, when the bonus game mode executing means for executing the bonus game mode in which the profit giving probability to the player is higher than that in the normal mode is provided, the special mode transition means is used for the game in the bonus game mode. Then, it is preferable to provide a special mode executing means for changing to the special mode after the bonus game mode in response to the right to change to the special mode being given by the special mode changing number lottery means. As a result, it is possible to continuously switch to the special mode and the bonus game mode, and the player can be expected to win a large number of medals in a short period of time. You can boost your sense of joy and increase your expectations for the game.

Further, a bonus game mode executing means for executing a bonus game mode in which a profit is more likely to be given to a player than in the normal mode is provided, and the number of games played after the bonus game mode is finished is counted. In the case where the game number counting means is provided and it is determined that the right to shift to the special mode is given by the special mode shift number lottery means before the number of games counted by the game number counting means reaches a predetermined number. It is preferable that the special mode shift means shifts to the special mode from the next game. As a result, after the bonus game mode ends, it is possible to play a small number of games and shift to the special mode, which gives the player the expectation to obtain a large number of medals in a short period of time. As a result, the player's motivation to play can be fueled and the sense of expectation for the game can be increased.

The program to be used is a special mode according to a winning combination determining means for determining a loss and one of a plurality of types of winning combinations by lottery, and a type of the loss or winning combination drawn by the winning combination determining means. The special mode transition number lottery means for determining whether or not to grant the right to shift to the special mode by lottery, and the number of transitions when the right to shift to the special mode is determined by lottery, and the special After the right to shift to the special mode is given by the mode shift number lottery means, one is selected from a plurality of special mode shift probability tables having different shift probabilities to the special mode, and the lottery is performed. Special mode transition means for transitioning from the normal mode to the special mode in response to winning, and the special mode transition number lottery means The number of transitions to the special mode is counted until the determined transition number is reached, and one preset in accordance with the count value is selected from the plurality of special mode transition probability tables and is selected by the special mode transition means. This is for causing the computer of the gaming machine to function as a special mode transition probability table switching means used for the lottery.

The recording medium to be used is a computer-readable medium in which the program according to claim 5 is recorded.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The slot machine 1 shown in FIG.
0 for BB as normal mode and bonus game mode
AT mode is provided as a mode and a special mode. The BB mode ends when the game is transferred to the RB mode three times or the game in the RB introduction mode is played 30 times. In the RB introduction mode, the game is played by inserting 1 to 3 medals, and the winning probability of the small winning combination is increased. Win the winning role to switch to RB mode in the RB introduction mode game,
When this is won, the mode is shifted to the RB mode. The RB mode ends when a predetermined winning combination is won eight times or when a game is played twelve times. When the AT mode wins the AT lottery, the right to shift to the AT mode is obtained, and the number of times to shift to the AT mode in the AT lottery is also determined. AT
The number of transitions to the mode is determined to be 1, 3, or 5 times.

The AT lottery is carried out when the player loses or wins a specific winning combination (for example, cherry) in the normal mode game, or when the player loses a particular winning combination in the RB introduction mode game. If you win the AT lottery in the normal mode game, the AT transition lottery will be performed from the next game,
If this lottery is won, the mode is switched to the AT mode. When the AT lottery is won in the RB introduction mode game, the AT transition lottery is not performed, and the AT mode is continuously shifted to the BB mode. Further, when the AT lottery is won within 100 games after the BB mode ends, the AT transition lottery is not performed and the AT mode is shifted from the next game. One AT
The mode ends when the game is played 13 times.

In the slot machine 10, four display windows 13 are provided on the front door 12 of the housing 11, and each display window 13 is provided.
A first reel 14a, a second reel 14b, a third reel 14c, and a sub reel 15 are rotatably incorporated in the inner part of the disk. As is well known, the first to third reels 14a to 14c
A plurality of types of winning patterns are arranged at a constant pitch on the outer periphery of, and three patterns per reel can be observed through the display window 13 when the reels are stopped. This allows
A total of 5 linear winning pay lines, each of which is a combination of the symbols on each reel, are set 3 horizontally and 2 diagonally.

The medal slot 16 prior to the start of the game
When one medal is thrown from, one horizontal winning line is activated in the center, and two horizontal lines, three horizontal lines and three diagonal lines, two diagonal lines are activated. . Further, it is possible to credit (store) up to 50 medals, and the number of credited medals is displayed by the credit number display unit 17. It is to be noted that, for example, four reels can be observed from the display window 13 per reel, and in addition to the four horizontal winning lines, another reel that is bent to combine one reel for each reel It is also possible to set an effective line.

The sub reel 15 at the right end functions as an informing means, and when the player wins a predetermined winning combination (for example, bell) in the AT mode game, the start lever 18
The rotation of the first to third reels 14a to 14c is started by this operation. On the outer circumference of the sub reel 15, first to third
A plurality of types of patterns indicating the order of performing the stop operation of the reels 14a to 14c are drawn, and in addition to these, a blank portion in which nothing is drawn is also provided. The sub reel 15
It is preferable that the pattern drawn on the outer circumference of the pattern is an appropriate pattern, and the pattern is not limited to the pattern and may be, for example, a mark or a number. Further, on the sub reel 15, an appropriate pattern is drawn to indicate that a specific winning combination has been won, or a pattern showing the degree of expectation of whether or not a specific winning combination has been won, and to give an appropriate notification. You may

The sub-reel 15 is normally stopped at a position where a blank portion is displayed, and when a bell is won in an AT mode game, the reels can be stopped in the order of stopping operation. It will be stopped at the display position. The player can certainly win the bell by operating the stop buttons 19a to 19c in the order displayed by the sub reel 15. The predetermined winning combination is not limited to the bell, and it is preferable to set an appropriate winning combination.

By operating the stop buttons 19a to 19c, the stop buttons 19a to 19c can be operated in accordance with the first to third buttons corresponding to the respective buttons.
The reels 14a to 14c are individually stopped. Various operation buttons such as a 1 bet button, a MAX bet button, and a payout button, which are operated when a game is played with a medal credited, are provided on the operation panel above the stop buttons 19a to 19c. Since the functions of these operation buttons are well known, their details are omitted.

A medal tray 20 is provided in the lower part of the casing 11, and the medal tray 20 is provided with payout medals 2 when a prize is won in a game.
It is paid out from 1.

As shown in FIG. 2, the operation of the slot machine 10 is basically controlled by a microcomputer including a CPU 30 and a memory 31. In addition to the control unit 30a, the CPU 30 is provided with an electronic lottery unit 39, a winning combination determination unit 40, an AT control unit 41, and a game number counter 42, which will be described later. The medal sensor 32 detects an appropriate medal inserted from the medal insertion slot 16 and inputs it to the control unit 30a. A selector is incorporated in the rear of the medal insertion slot 16, and improper medals are ejected to the medal tray 20.
Also, when the selector inserts medals at improper timing, for example, for medals inserted in the middle of the game or while various operation buttons are being pressed,
The coins are discharged to the medal tray 20 without passing through the medal sensor 32.

Since the number of medals to be inserted prior to the start of the game is limited to one to three, the medal sensor 32 also detects medals inserted after the fourth when the credit function is not used. It is discharged to the medal tray 20 without being played. The credit function is switched on / off for each push of the payout button. Then, when the credit function is turned on, medals inserted after the fourth one are also detected by the medal sensor 32, and 5
A maximum of 0 cards will be credited inside the slot machine.
The number of credited medals is digitally displayed on the credit number display unit 17. When the credit function is used, a medal insertion operation is performed by operating the 1 bet button or the MAX bet button, and the bet number is sequentially subtracted from the credit number. Also,
When a game is played and a prize accompanied by payout of medals is obtained, a dividend medal is also credited, and when the payout button is operated, the credited medal is paid out to the tray 20.

The control unit 30a determines the number of medals inserted from 1 to 3 prior to the start of the game by the medal sensor 32.
Based on the detection signal from, the number of activated winning lines is determined. The number of credits is counted by another credit medal counter (not shown).

The start signal sensor 33 inputs a game start signal to the controller 30a when the start lever 18 is operated after one to three medals have been inserted. In response to the game start signal, the control unit 30a causes the memory 31
The first to third reels 14a to 14c are rotated based on the game execution program stored in the ROM area, and the game process is started. The game execution programs also include BB mode and AT mode execution programs, and the control unit 30a executes the game in each mode by reading these execution programs. In addition, A
In the T mode game, the first to third reels 14a to 14a
At the same time as the rotation of c, the sub reel 15 is also rotated. As a result, the control unit 30a functions as a bonus game mode executing means.

The reel drive controller 34 controls the drive and stop of each reel. Each reel is fixed to the drive shaft of each individual stepping motor 35a to 35d, and each reel is controlled by controlling the drive of each stepping motor 35a to 35d. The RAM area of the memory 31 is a working area, and is used for temporary storage and rewriting of flags and data used for each game.

Since the stepping motors 35a to 35d rotate at a rotation angle corresponding to the number of supplied drive pulses, the control unit 30a controls the number of supplied drive pulses to control the first to third reels 14a to 14c and the reels 14a to 14c. The rotation angle of the sub reel 15 can be controlled, and the stop position of the reel can be determined by cutting off the supply of the drive pulse. Further, each reel is integrally formed with reflection signal portions 36a to 36d at its reference position, and the photosensors 37a to 37d photoelectrically detect the passage of each reflection signal portion every one rotation thereof. Photosensors 37a-3
The detection signal from 7d is input to the controller 30a as a reset signal for each reel.

The stepping motor 3 is installed in the control unit 30a.
A pulse counter is provided for each of 5a to 35d and counts the number of drive pulses supplied to each stepping motor 35a to 35d. Then, the photo sensor 37a-
When the reset signal is input from 37d, the count value of the corresponding pulse counter is cleared. Therefore, the number of drive pulses corresponding to the rotation angle within one rotation of each reel is sequentially updated and stored in each pulse counter.

A pattern table is stored in the ROM area of the memory 31, and the number of drive pulses corresponding to the rotation angle from the reference position of each reel and each pattern arranged on the reel at a constant pitch are stored in the ROM table. Is associated with the picture code representing. Therefore, by monitoring the count value of the pulse counter for each reel, it is possible to identify, for example, which pattern is moving on the winning line in the center, and how much more the reel is rotated. It is possible to predict whether the target pattern will move to the winning effective line.

The stop button sensors 38a-38c are
When the stop buttons 19a to 19c are operated, a stop signal for each reel is input to the control unit 30a. The start lever 18 is operated to start rotation of all reels, and when these rotations reach a steady speed, the stop button 1
The operations 9a to 19c are activated. Then, by operating these, stop control of the corresponding first to third reels 14a to 14c is started. As for the bell, the first to third so that the prize is won only when the stop buttons 19a to 19c are operated in a predetermined order.
Stop control of the reels 14a to 14c is performed.

The stop control of the first to third reels 14a to 14c is performed within the range of four winning symbols (withdrawal range), and when the stop buttons 19a to 19c are operated, for example, on the winning effective line. If the winning pattern that constitutes the winning combination that is won by the lottery is included in the four winning patterns that continue from the winning pattern located at, the first to third reels 14a to 14c are stopped. The time until it is delayed is delayed, and the winning symbols that make up the winning combination are stopped on the winning line. In addition, the bell patterns forming the bell are arranged such that the intervals between the bell patterns are within four winning patterns, and if the operation order of the stop buttons 19a to 19c is correct, the winning is performed regardless of the operation timing. As described above, the stop control of the first to third reels 14a to 14c is performed. As described above, the control unit 30a and the reel drive controller 34 function as reel stop control means.

The control section 30a receives the game start signal and operates the electronic lottery section 39. The electronic lottery section 39 includes a random number generator and a random value sampling circuit, and randomly selects one random value each time the game is started. The randomly selected random number value is input to the winning combination determination unit 40. The winning combination determination unit 40 determines what kind of winning combination will be given in the currently executed game according to the input value. In this way, the electronic lottery section 39 and the winning combination determining section 40 function as winning combination determining means.

The winning combination determining section 40 is provided with a plurality of winning combination determining tables in which random numbers are divided into groups according to their sizes. In the first winning combination determination table, the random number sampled in the game in the normal mode is BB that gives the right to shift to the BB mode, and the small winning combination corresponding to the small winning combination pattern that only pays out the predetermined number of medals. It is used to determine which pattern such as replay gives the right to play the next game with the same number of bets without throwing medals, loses without causing any hits, that is, the winning determination. It should be noted that there are a plurality of types of small winning symbols, and a payout medal is assigned to each of them. Then, the type of winning and the design are determined depending on which winning design the sampled random number value belongs to.

In addition to the first winning combination determining table, the winning combination determining section 40 is provided with a winning combination determining table used in the BB mode and the RB mode. When the winning combination determination unit 40 determines whether or not the winning combination is achieved, a winning combination determination signal indicating the determined loss or the type of winning combination is input to the control unit 30a.

As shown in FIG. 3, the AT control unit 41 is
T lottery section 50, AT right grant determination table 51a, transfer count determination table 51b, AT flag memory 52, AT
It is composed of a transition lottery section 53, a table switching signal generating section 54, a table selection lottery section 55, an AT transition probability selection table 56, a first transition determining section 57, and a second transition determining section 58.

The AT lottery section 50, the AT right grant determination table 51a, and the shift number determination table 51b function as a special mode shift number lottery means, and when the winning or winning combination is determined by the winning combination determining section 40, the AT is determined.
The lottery section 50 is operated to perform the AT lottery. The AT lottery unit 50 includes a random number generator and a random number sampling circuit, and a random number value is sampled each time it is activated. The sampled random number value is first collated with the AT right grant determination table 51a to determine whether to grant the right to shift to the AT mode. When it is determined to give the right to shift to the AT mode, the sampled random number value is collated with the shift number determination table 51b to determine the number of shifts to the AT mode.
In the transfer count determination table 51b, the random number groups are divided into groups for each transfer count. The group for each transfer count has one transfer to the AT mode,
It is composed of 3 types of groups, 3 times and 5 times. A
When it is decided to grant the right to shift to the T mode, the AT flags of the decided number of times are written in the AT flag memory 52. When one AT flag is read, the AT mode is entered once.

The AT shift lottery section 53 is activated when it is determined that the right to shift to the AT mode is given by the lottery by the AT lottery section 50, and the number of shifts to the AT mode is determined. A lottery will be held. The random number value sampled by the AT transition lottery section 53 is input to the first transition determination section 57 or the second transition determination section 58 depending on the number of times the AT mode has been transitioned. First transition determining unit 57
Is composed of an AT low transition probability table 59 and an AT high transition probability table 60. In the AT low transition probability table 59 and the AT high transition probability table 60, random number values are grouped so that the probabilities of transition to the AT mode are different from each other (for example, the AT low transition probability table 59).
Is 1/12, AT high transition probability table 60 is 1/4),
The random number value sampled by the AT transfer lottery unit 53 is A
Depending on the number of times the mode is switched to the T mode, it is collated with one of the tables to determine whether to switch to the AT mode.

The second transition determining unit 58 is composed of an AT low transition probability table 61, an AT mid transition probability table 62, and an AT high transition probability table 63, and the first transition determining unit 5
Similar to 7, the sampled random number value is collated with one of the tables to determine whether or not to shift to the AT mode. The AT low transition probability table 61, the AT mid transition probability table 62, and the AT high transition probability table 63 are grouped by random numbers so that the probabilities of transition to the AT mode are different from each other (for example, the AT low transition probability table 61 is 1). / 15, AT transition probability table 62 is 1 /
5, 1/3 for AT high transition probability table 63). When it is determined to shift to the AT mode, an AT mode shift signal is input to the control unit 30a, and the AT mode is shifted from the next game. As a result, the control unit 30a and the AT transition lottery unit 53 function as special mode transition means.

The table selection signal generation section 54 inputs a table selection signal indicating the type of the transition probability table used in the lottery in the AT transition lottery section 53 to the AT mode to the AT transition lottery section 53. The table selection signal generation unit 54 includes a transition count signal indicating the number of transitions to the AT mode counted by the control unit 30a or a table selection lottery unit 5 described later.
The lottery result signal from 5 is input. The table selection signal generator 54 determines the type of table selection signal to be output according to the input signal. As a result, the control unit 30a and the table selection signal generation unit 54 function as table switching means.

The table selection lottery section 55 is operated after the number of times of shifting to the AT mode reaches a predetermined number. The random number sampled by the table selection lottery unit 55 is AT
It is collated with the transition probability selection table 56. In the AT transition probability selection table 56, the
Low transition probability table 61, AT transition probability table 6
2. Three tables, that is, the ATAT high transition probability table 63 are assigned, and the sampled random number values are collated to determine which table is used to perform the AT transition lottery. As a result, the table selection lottery section 55 and the AT transition probability selection table 56 function as a special mode transition probability table determination means.

The game number counter 42 functions as a game number counting means and is operated after the BB mode ends. A game start signal is input to the game number counter 42 every time a game is played, and the number of times the game is played is counted. The count value of the game number counter 42 is monitored by the control unit 30a,
The number of games counted is a predetermined number (for example, 100
It will be cleared when the number of times reaches.

The medal hopper 43 pays out a specified number of payout medals to the medal tray 20 or adds the specified number to the credit counter according to the type of winning combination. The payout table in which the number of payout medals is determined for each type of winning combination is stored in the ROM area of the memory 31, and the control unit 30a reads this and drives the medal hopper 43.

Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 4 and FIG. 4, when 1 to 3 medals are inserted in the normal mode prior to the start of the game, the number of inserted medals is counted by the control unit 30a. After that, when the game start operation is performed by the start lever 18, the start signal sensor 33
Then, a game start signal is input to the control unit 30a, and the rotation of the first to third reels 14a to 14c is started.

At the same time, the electronic lottery section 39 samples a random number and collates the value with the first winning combination determination table of the winning combination determining section 40 to determine the type of the winning or winning combination, and the winning combination determining signal is given. It is fed back to the control unit 30a. When the winning combination determination section 40 determines the type of winning combination, the operation of the stop buttons 19a to 19c is validated.
The control unit 30a refers to the count value of the pulse counter provided for each reel and refers to the stop button 19
The winning award determination unit 4 is monitored by monitoring the operation timing of a to 19c.
The stop control of the first to third reels 14a to 14c is performed so that the winning pattern determined by 0 easily stops on the winning line.

When the winning combination determining section 40 determines the loss or the cherry, the control section 30a operates the AT lottery section 50. The AT lottery section 50 samples one random value. The sampled random number value is collated with the AT right grant determination table 51a to determine whether to grant the right to shift to the AT mode, and when it is determined to grant the right to shift to the AT mode. The sampled random number value is collated with the transition number determination table 51b, and the transition number is also determined at the same time. The result of the AT lottery is input to the control unit 30a. When the AT lottery is won, the determined number of AT flags are written in the AT flag memory 52. Then, from the next game, the AT transfer lottery section 53 is activated to perform the AT transfer lottery.

The control section 30a sends a transition count signal indicating the first AT mode to the table selection signal generation section 54.
To enter. The table selection signal generation unit 54 inputs a table selection signal indicating the AT low transition probability table 59 to the AT transition lottery unit 53. In response to this, the random number value sampled by the AT transfer lottery unit 53 is the first transfer determination unit 5
7 is checked against the AT low shift probability table 59 to determine whether to shift to the AT mode. A by AT transfer lottery
When it is determined to shift to the T mode, the AT mode shift signal is input to the control unit 30a. In response to the AT mode transition signal, the control unit 30a causes the AT flag memory 52
Read one AT flag written in
At the same time as subtracting "1", the execution program of the AT mode is read from the ROM area of the memory 31 and is shifted to the AT mode.

In the AT mode game, when the bell is won, the sub reel 15 is simultaneously rotated together with the first to third reels 14a to 14c. The control unit 30a uses the stop buttons 19a to 19c that make it possible to win the bell.
The stop control of the sub-reel 15 is performed so that the sub-reel 15 is stopped at the position where the operation sequence is displayed. The player can certainly win the bell by operating the stop buttons 19a to 19c in accordance with the operation sequence displayed on the sub reel 15. This allows the AT mode game to increase medals. The AT mode ends when the game is played 13 times.

The AT mode ends and the AT flag memory 5
If the AT flag is written in 2, that is, AT
When it is determined in the lottery that the right to shift to the AT mode 3 or 5 times is determined, the control unit 30a activates the AT shift lottery unit 53 again, and the table selection signal generating unit 54 causes The number-of-transitions signal indicating the second AT mode is input. A table selection signal indicating the AT low transition probability table 59 is input from the table selection signal generation unit 54 to the AT transition lottery unit 53. In response to this, the AT transition lottery section 53 compares the sampled random number value with the AT low transition probability table 59 of the first transition determination section 57 to perform the AT transition lottery. If the player wins the AT transfer lottery, the second AT mode is entered. In this case, since the AT transition lottery is performed using the AT low transition probability table 59, it is difficult to transition to the AT mode. As a result, it is difficult for the player to determine whether the determined number of transitions to the AT mode is one or more, or to play the game with a small number of times. it can.

When the second AT mode ends, the control unit 30a activates the AT transition lottery unit 53 and inputs the transition number signal indicating that the next AT mode is in the table selection signal generating unit 54 next time. To do. A table selection signal indicating the AT high transition probability table 60 is input from the table selection signal generation unit 54. In response to this,
The AT transition lottery section 53 compares the sampled random number value with the ATAT high transition probability table 60 of the first transition determination section 57 to perform the AT transition lottery. Since the number of times of shifting to the AT mode is one of three times, and five times, the second A
When the mode is changed to the T mode, the AT mode is surely changed three or five times. Therefore, by increasing the winning probability of the AT transfer lottery after the transfer to the second AT mode, it is possible to prevent the game from being delayed. If you win the AT transfer lottery, you will be transferred to the third AT mode.

When the third AT mode is completed and the AT flag is written in the AT flag memory 52, that is, when it is determined that the number of times the AT mode is switched to the AT mode is five. The control unit 30a again causes the AT transfer lottery unit 53 to perform the AT transfer lottery using the AT low transfer probability table 59. If the player wins the AT transfer lottery, the mode is switched to the fourth AT mode. In this case, since the AT transition lottery is performed using the AT low transition probability table 59, it is difficult to transition to the AT mode. As a result, it is difficult for the player to determine whether the determined number of transitions to the AT mode is three or five, or to play the game with a small number of times. it can.

When the fourth AT mode is finished and the AT flag is written in the AT flag memory 52,
The control unit 30a operates the AT transfer lottery unit 53. Further, the table selection lottery section 55 is activated to perform the table selection lottery. The random number values sampled by the table selection lottery section 55 are collated with the AT transition probability selection table 56 to determine the transition probability table used in the AT transition lottery. When the lottery is completed, the lottery result signal is input to the table selection signal generator 54. In response to this, the table selection signal generation unit 54 is activated, and the table selection signal indicating the determined type is input to the AT transfer lottery unit 53.

The AT transfer lottery unit 53 is connected to the second transfer determination unit 5
The AT transition lottery is performed using the transition probability table determined by the lottery in the table selection lottery unit 55 among the AT low transition probability table 61, the AT mid-transition probability table 62, and the AT high transition probability table 63 of FIG. The number of transitions to the AT mode is one, three, or five, so if the fourth transition to the AT mode occurs, the AT mode is surely changed to five.
Will be transferred twice. Since the combined probability (3/5) of each transition probability table of the second transition determination unit 58 is set to be higher than the winning probability of the AT low transition probability table 59, it is possible to prevent the game from being delayed. it can. In addition, since the winning probability of the AT transfer lottery is selected by a lottery from among three types of probabilities, it is possible to prevent the game from becoming monotonous. If the AT transfer lottery is won, the mode is switched to the fifth AT mode, and when the AT mode is finished, the mode is switched to the normal mode.

It should be noted that the number of transitions to the AT mode is 1,
As prior knowledge when playing the game that the number of times is 3, 5 or any number of times, for example, a sticker or the like is attached to the housing 11, or the slot machine 1 is installed in the game hall.
If the player is notified by a method such as distributing a strategy booklet describing the 0 game method, when the present invention is carried out,
This is more effective in making the player feel a sense of tension during the game between the AT modes.

When the player wins BB in the normal mode game, when the prize is won, the payout medals are paid out, and the normal mode is changed to the BB mode. When the mode is changed to the BB mode, the winning combination determination table is switched, and the game is performed in the RB mode and the RB introduction mode which is changed before the RB mode. In the RB introduction mode, the game is played with 1 to 3 medal bets. In the game of the RB introduction mode, the winning combination to be switched to the RB mode is won, and when the winning combination is won, the game is transferred to the RB mode. In the RB mode, it ends when a predetermined winning combination is won or 12 games are played. In BB mode, games in RB introduction mode are played 30 times or R
When the B mode is entered three times, the process ends.

Even if the player loses or cherries in the RB introduction mode game, the AT lottery section 50 is activated and A
T lottery will be held. When the AT lottery is won in the RB introduction mode, the AT flags for the determined number of times are written in the AT flag memory 52. Then, the control unit 30a sets B
After the B mode ends, the first AT mode is started. A
When it is decided to shift to the T mode 3 or 5 times, as described above, as in the case where the AT lottery is won in the normal mode except within 100 games after the end of the BB, the AT
Selection of the transition probability table and determination by lottery are performed according to the number of transitions to the mode. In this case, since the BB mode is continuously changed to the AT mode, the player can acquire a large number of medals in a short period of time. Therefore, the player's interest in the BB mode can be increased.

When the AT lottery in the RB introduction mode game is not won, when the BB mode ends, the mode is shifted to the normal mode. In this case, the control unit 30a operates the game number counter 42 to monitor the number of games played after the end of BB. When the AT lottery is won within 100 games after the BB ends, the control unit 30a shifts to the first AT mode from the next game. A
If it is decided to switch to T mode 3 or 5 times, like the time when you win the AT lottery in the normal mode except within 100 games after the end of BB, the transition probability depends on the number of transitions to AT mode. Table selection and lottery decisions are made. Also in this case, if you win the AT lottery, BB
Since the mode is switched to the AT mode by playing the game only a few times after the mode ends, the player can obtain a large number of medals in a short period of time. Therefore, the player's interest in the game after the end of the BB mode can be increased.

In FIG. 6, a recording medium (CD, flexible disk, IC memory, MO, etc.) 70 is connected to the slot machine 10.
The example shown in the flowcharts of FIGS. 4 and 5 is installed in the recording medium 70 as C.
A program to be realized by the computer 71 including the PU 30 and the memory 31 is stored. In this case, for example, winning combination determination means, reel stop control means, notification means,
The special mode transition number lottery means, the special mode transition means, and the special mode transition probability table switching means are provided on the computer 71.
The program to be realized by is recorded in the recording medium 70. Then, the recording medium 70 is loaded into the reading device 72, and the program is installed in the slot machine 10.

The program can be distributed to the slot machine 10 using the Internet instead of being installed via the recording medium 70. Further, the distributed program of the present invention or the recording medium 70.
It is also possible to install the program of the present invention read out from the computer into a personal computer and play a slot machine game on the monitor.

In the above embodiment, the winning probability in the AT lottery section is set to one type, but the winning probability of the AT lottery may be set appropriately, and the number of times of shifting to the AT mode may be set appropriately. Good. In this case, for example, the winning probability of the AT lottery is increased within 100 games after the BB mode is finished, after the payout rate is changed, and after the number of games played in the BB mode reaches a predetermined number,
If the number of transitions to the T mode is more likely to occur than when the AT lottery is won in the normal mode, the player's interest in the game can be increased.

In the above embodiment, the player is informed of the mode of the reel stop operation in the AT mode game using the sub reel 15. However, for example, an appropriate means such as a liquid crystal panel, a dot matrix display, or a voice is used. You may Also,
The mode of reel stop operation is, for example, when the small prize winning symbols are arranged so that the interval for each winning symbol is equal to or more than the pull-in range, and when one of the small symbol winning symbols arranged in this way is won. An appropriate mode may be used, such as notifying a winning combination winning pattern to be stopped on the winning effective line, or combining notification of a winning combination winning pattern and notification of the operation order of the stop button.

In the above embodiment, the AT mode end condition is that the game is played 13 times.
The AT mode ending condition may be an appropriate condition such that the small winning combination is won a predetermined number of times in addition to the game being played once.

In the above embodiment, only the BB mode is provided as the bonus game mode. However, in addition to the BB mode, the RB mode and the SB mode in which only one game has a higher winning probability, and the probability of shifting to the SB mode are higher. A centralized mode or the like may be provided separately.

In the above-described embodiment, winning the cherry or losing is the trigger for the AT lottery. However, when the RB mode is provided as the bonus game mode, for example, the winning of the RB is the trigger for the AT lottery. In addition to providing multiple types of loses, when the specific lose is won, the reel stop control is performed so that the corresponding winning pattern is easily stopped on the winning effective line. The winning lottery that triggers the AT lottery may be an appropriate winning lottery, such as the AT lottery being held when the winning pattern corresponding to a specific loss is stopped on the winning line. .

In the above embodiment, the first transition determining unit 57 is provided with two types of special mode transition probability tables, and the second transition determining unit 58 is provided with three types of special mode transition probability tables. The type of table may be appropriately set.

In the above embodiment, the AT is set as the special mode.
Although the mode is provided, as the special mode, a CT mode, an RT mode, an ART mode or the like may be provided in addition to the AT mode.

To provide the CT mode, for example, only when the winning combination determining section 40 determines BB, RB, and replay, the control section 30a and the reel drive controller 34 control the stop of the first to third reels 14a to 14c. When the loss or the small winning combination is determined, the stop control of the first to third reels 14a to 14c may not be performed. As a result, even if the winning combination is determined by the winning combination determination unit 40, the operation timing of the stop buttons 19a to 19c is prioritized and the first to third reels 14a to 14c are stopped, so that the player measures the timing. By operating the stop buttons 19a to 19c, it is possible to win a small winning combination and increase medals during the CT mode. In the CT mode, it is preferable to count the net number of medals acquired in the CT mode and the number of games played in the CT mode, and shift to the normal mode when either of them reaches the upper limit. .

To provide the RT mode, for example, the winning combination determining section 40 is provided with a winning combination determining table for the RT mode in which random numbers are grouped so that the probability of winning the replay is high, and the electronic lottery section 39 performs sampling. The generated random number value may be collated with the winning combination determination table for RT mode. In addition, the number of games is counted by the control unit 30a. This allows the player to play the game while suppressing the consumption of medals during the RT mode.

To provide the ART mode, for example, the winning combination determining section 40 is provided with a winning combination determining table for the RT mode in which random numbers are grouped so that the probability of winning the replay becomes high, and the RT mode is set in the AT mode. The lottery may be performed by using the winning combination determination table for. In addition, the number of games is counted by the control unit 30a. This allows the player to increase medals while suppressing consumption of medals during the ART mode.

The present invention is not limited to reel drive type slot machines, but is equally applicable to video type slot machines and pachinko machines. Further, as in the above-described embodiment, the winning line is three horizontal lines,
The present invention is not limited to a game machine in which two diagonal lines are set for a total of five, and the present invention can be applied to a game machine having another number of winning effective lines.

[0076]

As described above, according to the present invention, the number of transitions to the special mode is counted until the determined transition number is reached, and the preset 1 is set according to the count value.
One of the special mode transition probability tables is selected, and a lottery is performed to determine whether or not to switch from the normal mode to the special mode. Therefore, in a game between special modes, the normal mode is switched to the special mode. If the lottery to decide whether or not to perform is performed using a special mode transition probability table with a low transition probability, for example, even if the game is played a small number of times to be transitioned to the special mode, it cannot be detected by the player. Therefore, a tension can be given to the game between the special modes. In addition, if the number of transitions to the special mode until the next special mode is one of the preset number of transitions of a plurality of types, a lottery of whether to transition from the normal mode to the special mode By using, for example, a special mode transition probability table with a high transition probability, the special mode is transitioned with a small number of games,
It is possible to prevent the game from being delayed.
