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 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 and won by playing a game. You can exchange medals 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. Especially, the BB mode is RB mode.
Since the mode is changed to the predetermined number of times and the mode is changed to the RB introduction mode in which the winning probability of the small winning combination is increased before the mode is changed to the RB mode, a large number of medals can be acquired in a short period of time.

It should be noted that, in the present specification, a pachi-slot machine is used as an example for explanation, and therefore, explanation will be made using medals as a game medium, but the game medium also includes other media such as coins and pachinko balls. In addition, "inserting a medal (game medium)" includes betting a credited medal with a bet button or the like, in addition to actually inserting the medal into the medal insertion slot. 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.

It is an important factor to attract a player to a slot machine to have the expectation that a large number of medals can be obtained in a short period of time, and in recent years, a large number of medals can be expected in addition to the bonus game mode. There are many models that have been devised in various ways, such as by providing a game mode, to encourage the players' ambition. As one of the game modes, an assist time (AT) mode is known in which an assist display that prompts the player to operate a stop button is displayed. In the AT mode, for example, a sub reel provided separately from the three reels, a liquid crystal panel, or the like displays the pattern to be stopped on the winning effective line, the operation sequence of the stop button, and the like to the player. When the player operates the stop button in accordance with this display, it becomes easy to win the small winning combination having the internal winning, and thus it is easy to increase the medals in the AT mode.

As one of the models provided with the AT mode, for example, there is one in which the game is switched to the AT mode when a game in the normal mode is successively won a plurality of times for replay.
In this model, the reels are controlled so that even if a specific winning combination is won inside the normal mode, the specific winning combination cannot be won unless the stop button is operated in a predetermined order. Then, in the AT mode, when the specific winning combination wins the internal prize, the operation sequence of the stop buttons that can win the winning combination is displayed. Also, with this model, in a predetermined number of games after the BB mode and after the AT mode is finished, it is only necessary to win the replay once.
A chance mode for shifting to the T mode is provided. As a result, the number of times of shifting to the AT mode can be easily increased, and the player can have a great sense of expectation for obtaining a large number of medals.

[0006]

However, in the above slot machine, the number of games in the chance mode is set to a preset number of games, and since the number of games is only a few games, It is rare that the AT mode is entered again. Therefore, the chance mode has a drawback that it is not interesting from the viewpoint of increasing the number of transitions to the AT mode and making the player have an expectation for obtaining a large number of medals.

In order to solve the above problems, the present invention provides a game machine, a program, and a recording medium which allow a player to have an expectation that a large number of medals can be won in a short period of time. To aim.

[0008]

In order to achieve the above object, the gaming machine of the present invention is a winning combination determining means for determining a loss and one of a plurality of winning combinations by lottery, and a stopping operation of the player. Reel stop control means for controlling the reel stop according to the above, and when a predetermined condition is satisfied while playing the game in the normal mode, the mode is shifted to the specific mode, In the game, an assist display urging the player to stop the operation so that the winning combination determined by the winning combination determining means can be easily obtained is displayed, and after the specific mode ends, the predetermined condition is relaxed to enter the specific mode. In a gaming machine provided with a chance period that facilitates transition, a chance game that changes the number of chance games that can be executed during the chance period after the specific mode is finished It is provided with a section means.

As the specific mode, it is effective to provide an AT mode, a CT mode, an RT mode, an ART mode or the like 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 winning probability of the replay that allows the next game to be played without inserting medals has a higher probability than that of the normal mode in a predetermined number of games. 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 game history storage means for storing a specific game history of the game from the end of the previous specific mode to the start of the current specific mode is provided, the chance game adjusting means is provided. It is preferable to adjust the number of chance games according to the history stored in the game history storage means. In this case, the specific game history in the game includes the number of times the game has been played, time, the number of inserted medals, and the difference between the number of inserted medals and the number of paid-out medals. That is.

Further, the game history storage means counts the number of times the game is played as the specific game history, and between the preceding specific mode and the subsequent specific mode. While the number of games played is less than or equal to a predetermined number, it is equipped with a continuous number counter that determines that these specific modes are continuous and counts the number of continuous times, and a chance period after the continuous specific mode ends. It is preferable that the number of chance games that can be executed is changed according to the count number of the continuous number counter.

Further, the predetermined condition is that the specific winning combination is determined by the winning combination determining means. When the predetermined condition is relaxed, a winning combination having a higher winning probability than the specific winning combination is won. It is preferable that the transition to the specific mode is performed on the condition that the winning combination determination means determines the winning combination.

In addition to the above, the predetermined condition is that the specific winning combination is determined by the winning combination determining means and the specific winning combination is obtained. When the predetermined condition is relaxed, the specific winning combination is obtained. The transition to the specific mode may be performed on the condition that the winning combination is determined.

Furthermore, the predetermined condition is that a specific winning combination is obtained a predetermined number of times during a predetermined number of game periods, and when the predetermined condition is relaxed, the specific winning combination is performed during the predetermined number of game periods. The transition to the specific mode may be performed on the condition that the number of times the winning combination is obtained is smaller than the predetermined number.

The program to be used is a winning combination determining means for randomly selecting one of a winning combination and a plurality of kinds of winning combinations, and a reel stop control means for controlling the reels to stop in accordance with the player's stopping operation. The computer of the gaming machine functions as a chance game adjusting unit that changes the number of chance games that can be executed during the chance period after the specific mode ends.

The recording medium used is a computer-readable medium in which the program according to claim 7 is recorded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a slot machine 10 is provided with four modes: a normal mode, a BB mode, an AT mode as a specific mode, and a chance mode as a chance period. The end condition of the BB mode is that the RB introduction game is executed three times or 30 times before the RB mode is transferred to the RB mode. In the AT mode, the game can be played 13 times, and the transition to the AT mode is to win the replay (re-play) three games in a row in the normal mode, or to perform the AT in the normal mode. It is done by winning the lottery. The chance mode is changed after the AT mode is finished, and in the chance game in the chance mode, it is changed to the AT mode by winning the replay only once. Also, as will be described later in detail, the probability of winning the replay is high in 100 games after the BB mode ends,
It becomes easy to shift to the AT mode.

In the slot machine 10, four display windows 13 are provided on a front door 12 of a 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 patterns are arrayed 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. As a result, a total of 5 linear winning pay lines in which the patterns of the respective reels are combined one by one and three diagonally by two are set.

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 indicator 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 starts to rotate together with the other reels 14a to 14c when the start lever 18 is operated in the AT mode game. Sub reel 1
Numeral 5 is an assist display for the player, in which a plurality of small winning patterns and replay winning patterns are arranged, and
There is also a blank area where nothing is drawn. Then, the sub reel 15 displays a small winning combination winning pattern when a small winning combination is won by an electronic lottery at the start of the game, a position where a replay winning winning design is displayed when winning a replay, and nothing is displayed when winning is lost It is stopped at each position.

By operating the stop buttons 19a to 19c, the first to third stop buttons 19a to 19c corresponding to the respective buttons are operated.
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 portion of the housing 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 includes an electronic lottery unit 41, a winning combination determination unit 42, an AT mode lottery unit 43, an AT history memory 44, which will be described later.
A chance mode control unit 45 and an AT game number memory 46 are provided. The medal sensor 32 is the medal insertion slot 16
An appropriate medal inserted from is detected and input 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, the selector does not pass through the medal sensor 32 even when a medal is inserted at an improper timing, for example, a medal that is inserted in the middle of a game or while various operation buttons are being pressed. Medal tray 20
To discharge.

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. 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. In addition, when a winning is obtained as a result of the game, the payout medal is also credited, and the credited medal is paid out to the tray 20 when the payout button is operated.

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 bet number of medals thrown at each start of the game is calculated by the throwing medal counter 3
3 is added up and counted. The number of credits is counted by another credit medal counter (not shown).

The start signal generator 34 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. Further, in the notification game, the sub reel 15 is rotated simultaneously with the rotation of the first to third reels 14a to 14c.

The reel drive controller 35 controls the drive and stop of each reel. Each reel is fixed to the drive shaft of each individual stepping motor 36a to 36d, and each reel is controlled by controlling the drive of each stepping motor 36a to 36d. 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 36a to 36d 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 37a to 37d at its reference position, and the photosensors 38a to 38d photoelectrically detect the passage of each reflection signal portion every one rotation thereof. Photosensors 38a-3
The detection signal from 8d is input from the reset signal generator 39 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 6a to 36d and counts the number of drive pulses supplied to each stepping motor 36a to 36d. Then, the reset signal generator 3
When the reset signal is input from 9, 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 signal generator 40 inputs a stop signal for each reel to the control section 30a when the stop buttons 19a to 19c are operated. Start lever 1
When all the reels start rotating by operating 8, and when these rotations reach the steady speed, the stop buttons 19a to 19c
The operation of is enabled. After that, by operating these, the corresponding first to third reels 14a to 14a
The stop control of 4c is started. It should be noted that when a plurality of stop buttons are operated, only the reel with the earlier timing is stopped, and when completely simultaneously operated, none of the reels is stopped. As a result, the controller 30a and the reel drive controller 35 function as reel stop control means.

The control section 30a receives the game start signal and operates the electronic lottery section 41. The electronic lottery section 41 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 42. The winning combination determining unit 42 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 41 and the winning combination determining section 42 function as winning combination determining means.

The winning combination determining section 42 is provided with a plurality of winning tables in which random number values are divided into groups according to their sizes. In the first winning table, the random number values sampled in the game in the normal mode are BBs that give the right to shift to the BB mode, small wins corresponding to the small win winning symbols that only pay out a predetermined number of medals, and medals. It is used for determining which of the symbols, such as a replay that gives the right to play the next game with the same number of bets without throwing, a loss that does not cause any hits, that is, a 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.

The second winning table is used for winning determination in 100 games after the BB mode ends. Similar to the first winning table, in the second winning table, BB, small win, replay, and loss are assigned to the random number group, and the winning probability of replay is higher than that in the first winning table. In addition to the first and second winning tables, the winning combination determining section 42 is provided with a table used in the RB introduction game and a winning table used in the RB mode. A winning combination determination signal indicating the type of winning combination determined by the winning combination determining unit 42 is input to the control unit 30a.

The AT mode lottery section 43 is activated each time a game start operation is performed in a normal mode game. The AT mode lottery section 43 is provided with a random number generator, a random number sampling circuit, and a winning table, and each time a game is started, it is determined by lottery whether or not to shift to the AT mode from the next game. When it is decided to shift to the AT mode, the AT shift decision signal is sent to the control unit 30a.
Entered in.

In the AT history memory 44, the number of games played during the AT mode is written as a game history on the game by the chance mode control unit 45. In the chance mode game number memory 46, the number of playable chance games is divided and written, for example, “10 times”, “30 times”, and “50 times”. The chance mode control unit 45 reads the number of games written in the AT history memory 44 so that the number of games played between the preceding AT mode and the subsequent AT mode is a predetermined number of times. While the number of times is below (for example, 10 times or less), it is determined that these AT modes are continuous and the number of continuous times is counted. Then, one of the game numbers is read from the chance mode game number memory 46 according to the counted number of consecutive times, and the number of chance games that can be played in the chance mode after the current AT mode is finished is determined. When the number of games is determined, a game number determination signal is input to the control unit 30a. In this way, the AT history memory 4
4 and the chance mode control unit 45 function as a game history storage unit and a continuous number counter, and the chance mode control unit 45 and the chance mode game number memory 46 function as a chance game adjusting unit.

The medal hopper 48 pays out a specified number of payout medals to the medal tray 20 according to the type of winning combination, or adds the specified number to the credit counter. A 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 the payout table and drives the medal hopper 48. The number of payout medals corresponding to the small winning combination is the same in both the normal mode and the BB mode.

Next, the operation of the slot machine configured as described above will be described. As shown in FIG. 3, first, when 1 to 3 medals are inserted prior to the start of the game in the normal mode, the inserted medal counter 33 counts the number of inserted medals. Thereafter, when the game start operation is performed by the start lever 18, the game start signal is input to the control unit 30a, and the first to third reels 14 are driven.
a to 14c start rotating all at once.

At the same time, the electronic lottery section 41 samples a random number, and collates the value with the first winning table of the winning combination determining section 42 to determine the type of loss or winning combination.
Further, the AT mode lottery section 43 is operated to determine whether or not to shift to the AT mode from the next game.

When the replay is determined by the lottery of the winning combination determining section 42, the winning record of the replay is written in the memory 31. Then, when the replay is won for three consecutive games and the winning record written in the memory 31 becomes "3", A
Transition to T mode. Even if the player wins the replay, the winning record written in the memory 31 is cleared if three games are not consecutively played. Also, the AT mode transition lottery section 43
Even if it is decided to switch to AT mode, A
Transition to T mode. When it is determined to shift to the AT mode, the AT shift determination signal is input to the control unit 30a. When shifting to the AT mode, the number of games played from the end of the previous AT mode to the start of the current AT mode is written in the AT history memory 44.

In the AT mode game, when the game start operation is performed, the sub reel 15 is rotated together with the first to third reels 14a to 14c. When the winning combination determination unit 42 determines the small winning combination, the sub reel 15 is stopped at a position where the small winning combination winning pattern of the winning small winning combination is displayed. After the sub reel 15 is stopped, the stop buttons 19a to 19c are activated. The player timely stops the stop button 19a so that the winning combination pattern displayed on the sub reel 15 is stopped on the winning effective line and the winning is obtained.
Operate ~ 19c. When the small winning combination is won, the control unit 30a
Activates the medal hopper 48 to pay out the number of payout medals corresponding to the type of the winning combination winning picture. When the replay or loss is determined by the winning combination determination unit 42, the sub reel 15 is stopped at the position where the replay winning pattern is displayed or the position where nothing is displayed, and the game processing corresponding to each is performed. The number of games played in the AT mode is counted up by the control unit 30a, and the R of the memory 31 is read.
It is written in the AM area. Then, when the number of games played in the AT mode reaches 13, the AT mode is ended.

When the AT mode ends, the chance mode is entered. When shifting to the chance mode, the chance mode control unit 45 determines the number of chance games that can be played in the chance mode after the current AT mode ends.

When determining the number of games, the chance mode control unit 45 counts the number of continuous AT modes from the AT history memory 44. As shown in FIG. 4A, for example, after the AT mode of the last two times is completed,
The number of games played before the T mode was started was 11 or more.
When the number of games played before the transition to the T mode is 10 or less, it is determined that the number of consecutive AT modes is two, which is a so-called two consecutive chan. Figure 4
As shown in (B), the number of games played between the preceding AT mode and the subsequent AT mode is 10 or less, and the current AT mode is continuously changed twice. If it is performed, the number of continuous AT modes is determined to be 3, and it is identified as 3 consecutive chans. As shown in FIG. 4C, the number of games played between the preceding AT mode and the subsequent AT mode is 10 or less, and the current AT mode is continued twice. In the case of shifting to (4), it is determined that the number of continuous AT modes is four, and it is identified as four consecutive chans. As shown in FIG. 4 (D), the number of games played between the AT mode that has been shifted to the previous mode and the AT mode that has been shifted to the subsequent mode is 10 games or less, and the current AT mode is continued four times. In case of shifting to No. 5, the number of continuous AT modes is determined to be 5, and it is identified as 5 consecutive chan.
As shown in FIG. 4 (E), if the number of games played from the end of the previous AT mode to the shift to the current AT mode is 11 or more, continuous AT mode is performed. The number of times is identified as one.

Then, as shown in FIGS. 4 (A) and 4 (E), when the AT mode transferred this time is identified as the second consecutive chunk or the consecutive number is the first, the number of chance mode games is determined. The number of games “50” is read from the memory 46, and the number-of-games determination signal corresponding to this is read out by the control unit 30.
Input to a. As shown in FIGS. 4B and 4C,
The AT mode that was changed this time is the 3rd consecutive Chan, or 4
When it is identified that the number of games is consecutive, the number of games “30” is read from the chance mode game number memory 46, and the corresponding game number determination signal is input to the control unit 30a. As shown in FIG. 4 (D), when it is identified that the AT mode transferred this time is the fifth consecutive chunk, the number of games “10” is read, and the number-of-games determination signal corresponding to this is read. It is input to the control unit 30a.

When the game number determination signal is input, the number of chance games that can be played is determined by the RAM of the memory 31.
Written to area. In the chance mode, the number of games written in the memory 31 is decremented by "1" every time a game is played, and the chance mode is continued until the number becomes "0".

In the chance mode, the replay is 3 times because the player shifts to the AT mode by winning the replay once.
It becomes easier to shift to the AT mode than the normal mode, which requires winning the game continuously. Also, the AT lottery is performed for each game even in the chance mode, and even if this is won, the AT mode is also shifted. If the number of consecutive chans in AT mode is small, the number of chance games that can be played increases, and as a result, the possibility of continuous chanting in AT mode increases, so a large number of medals can be obtained for the player in a short period of time. You can have expectations.

Thereafter, the operation of the stop buttons 19a to 19c is validated, and the control section 30a monitors the operation timing of the stop buttons 19a to 19c while referring to the count value of the above-mentioned pulse counter provided for each reel. , The stop control of the first to third reels 14a to 14c is performed so that the BB winning pattern is easily stopped on the winning effective line.

In the game in the normal mode, the winning combination determining section 4
BB is determined by 2, and when this is won, the payout medals are paid out and the mode is shifted to the BB mode. When the mode is changed to the BB mode, the winning table is switched, and the RB introduction game in the RB introduction mode and the RB game in the RB mode are played. The RB mode ends when 12 RB games are played or 8 winnings are obtained.
In BB mode, shift to RB mode three times or
The introductory game can be played 30 times, and is ended when either limit is reached.

When the BB mode is finished, the mode is shifted to the normal mode again, but in the 100 games after the BB mode is finished, the kind or loss of the winning combination is determined by using the second winning table. Since the random numbers in the second winning table are grouped so that the probability of winning the replay is higher than that in the first winning table, 100 games after BB ends are A
It becomes easy to shift to the T mode. As a result, the 100 games after the end of the BB mode can be a tense game. When a BB is won in a game in the AT mode or a game in the chance mode, the game is transferred to the AT mode or the chance mode again after the BB mode ends, and the remaining number of games can be played. Even in this case, since the winning table is switched to the second winning table, there is a high possibility of shifting to the AT mode, especially in the chance mode, and the player can have a great sense of expectation.

FIG. 5 shows a slot machine 10 in which a recording medium (CD, flexible disk, IC memory, MO, etc.) 60 is installed.
In the example shown in FIG. 3, the recording medium 60 is provided with means such as that shown in the flowchart of FIG.

In the above embodiment, the number of games that can be played in the AT mode is 13 games, the number of games in which the winning probability of replay after BB is high is 100, and the number of games that can be played in the chance mode is 10, 30, 50. Although it is a game, the number of these games may be set appropriately.

In the above embodiment, one of the conditions for shifting to the AT mode is to win the replay three games in succession during the normal mode. However, the number of games to win continuously and the winning combination are set appropriately. You can do it. Further, only one of winning the winning replay or winning the AT lottery for three consecutive replays may be a condition for shifting to the AT mode. If the only condition for shifting to the AT mode is to win the AT lottery, the probability of winning the AT lottery may be increased in the chance mode. Furthermore, if the number of games played between AT modes or between BB modes exceeds a predetermined number of games, or if the time elapsed between AT modes or between BB modes exceeds a predetermined time, the number of inserted medals The transition condition to the AT mode may be appropriately set, for example, the transition condition to the AT mode may be set when the difference between the number of medals and the number of paid-out medals exceeds a predetermined number.

In the above embodiment, in the normal mode, winning the replay three games in succession is set as the condition for shifting to the AT mode, and in the chance mode, the condition for shifting to the AT mode is relaxed, and the player is won once for the replay. Although the condition for transitioning to AT mode is set, for example, winning a specific winning combination in the normal mode is set as a transition condition for AT mode, and selecting a winning combination with a higher probability of winning than a specific winning combination in the chance mode. It may be a condition for shifting to the AT mode. In this case, when the winning combination determining unit 40 determines the specific winning combination in the normal mode and the winning combination having a lower winning probability than the specific winning combination in the chance mode, the control unit 30a
Should be switched to the AT mode.

In addition, for example, in the normal mode, winning a specific winning combination and winning the specific winning combination is a transition condition to the AT mode, and in the chance mode winning a specific winning combination is
It may be a condition for shifting to the T mode. In this case, for example, stop control of the first to third reels 14a to 14c is performed within a range of four winning symbols (withdrawal range), and when the stop buttons 19a to 19c are operated, the winning line is activated. In the case where the winning pattern that forms the winning combination that is won by the lottery is included in the four winning patterns that are continuous from the positioned winning pattern, the first to third reels 14a to 14a
The time until 4c is stopped is delayed so that the winning symbols constituting the winning combination are stopped on the winning effective line. Then, the intervals between the winning symbols that constitute the specific winning combination may be set to five winning symbols or more. Control unit 30a
In the normal mode, when the specific winning combination is determined by the winning combination determining unit 40 and the stop buttons 19a to 19c are operated so that the specific winning combination is won, the mode shifts to the AT mode, and in the chance mode. When the specific winning combination is determined by the winning combination determining unit 40, the mode is shifted to the AT mode. In addition to these methods, an appropriate method may be used as a method for relaxing the conditions for shifting to the AT mode.

In the above embodiment, the AT history memory 44
The number of times the game was played was written as the game history in the game, but the number of medals inserted as the game history in the game, the number of inserted medals and the number of paid-out medals The difference number, time, etc. may be written. In this case, the chance mode control unit 45
The number of chance games according to each history may be read from the chance mode game number memory 46.

In the above embodiment, the number of chance games that can be played decreases as the number of consecutive chans increases, but the number of chance games may be set appropriately. Further, although the case where the number of games played during the AT mode is 10 is defined as the continuous chan, the number of games between the AT modes for defining the continuous chan may be appropriate. In the chance mode game, 1 for replay.
When the player wins the game, the AT mode is entered, but the number of times may be set appropriately. Furthermore, for example, when a player wins replays consecutively in a predetermined number of chance games, the content of the game in the chance mode is changed to the AT mode rather than the normal mode, such as shifting to the AT mode in which 1000 games can be played. Appropriate settings can be made as long as the transition becomes easy.

In the above embodiment, in the AT mode game, the small winning combination notified by the sub reel 15 is selected from a plurality of types of small winning combinations to win the prize. However, for example, a specific small winning prize is internally won. In this case, the stop control of the first to third reels 14a to 14c is performed so that the winning is won only when the stop buttons 19a to 19c are operated in a predetermined order. In the AT mode game, The operation order of the stop buttons 19a to 19c may be notified.

In the above embodiment, 1 after the BB mode is finished.
Although the probability of winning replays in games 00 is increased, the probability of winning replays is increased during a predetermined number of games after the AT mode ends, or if a predetermined condition is satisfied during normal mode, The winning probability of the replay may be increased at an appropriate timing, such as increasing the winning probability of the inter-replay.

In the above embodiment, the number of games that can be played in the chance mode is adjusted according to the number of games played in the AT mode. However, for example, BB regardless of the game history in the game. When a certain number of games have been played between modes or when a specific winning combination has been won,
The number of games that can be played in the chance mode may be adjusted with an appropriate opportunity.

In the above embodiment, only the BB mode is provided as the bonus game mode.
A mode may be provided.

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

The stop control of 14c is performed, and the stop control of the first to third reels 14a to 14c may not be performed when a loss or a small winning combination is determined. As a result, even if the winning combination determination unit 40 determines the loss, the stop button 19a-
Since the operation timing of 19c is prioritized and the first to third reels 14a to 14c are stopped, the player can win the small winning combination by measuring the timing and operating the stop buttons 19a to 19c. Therefore, medals can be increased during the CT mode. In the CT mode, the net increase in the number of medals acquired during the CT mode and C
Count the number of games played in T mode,
