DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, and more particularly to a slot machine which can reflect a player's intention in determining a game advantage.

[0002]

2. Description of the Related Art In general, a slot machine is provided with a variable display device having a plurality of reels on which a plurality of types of symbols are drawn on an outer peripheral portion, and a display mode when rotation of each reel is stopped is a predetermined prize. In this mode, medals are paid out as valuable value. In addition, the display mode when the rotation of each reel is stopped becomes a special winning mode, thereby creating an advantageous gaming state for the player such as a big bonus or a regular bonus, so that the player can acquire many medals. Is what it is.

[0003] In recent slot machines, an AT (Assist Tim) is used to further enhance the interest of the game.
e), a game state such as CT (Challenge Time), RT (Replay Time), which is more advantageous than a normal game state, but a specific game state different from the special game state described above may be provided.

[0004] These specific game states generally occur at a predetermined probability at a timing related to the end of the big bonus. Then, when the number of games reaches a predetermined number or when a bonus winning flag is set, the game is terminated. In some cases, the number of continuous games is changed by lottery. As described above, the game is provided with a variety of advantages from the occurrence of the big bonus to the end of the specific game state, thereby improving the interest in the game. Conventionally, the occurrence probability of the specific game state and the number of continuous games have been conventionally left to the machine-side lottery result.

[0005]

However, each of the players has a unique preference for the progress of the game, and a player who wishes to continue the advantageous game state for a long time even if the probability of occurrence is low, or There are various people who want a high probability of occurrence even if the duration of the gaming state is short. That is, the conventional slot machine could not allow the players to proceed with the game according to their own preferences.

There are also slot machines provided with two types of big bonuses having different advantages, for example, a super big and a normal big, in order to give the game a variety of advantages after the occurrence of the big bonus. The assignment between Super Big and Normal Big is usually completely left to the machine draw. However, some of them can generate a super big advantage by progressing the game in a special way.

[0007] However, when the game is advanced by this special method, the game always becomes a super big, and the change in the advantage does not accompany the accident. For this reason, it is not possible to give the player any sense of expectation from here. In addition, progressing the game in this special method requires considerable skill, and is not possible for any player.

An object of the present invention is to provide a slot machine which enhances amusement of a game by reflecting a player's intention in determination of a game advantage within a predetermined period from occurrence of a special winning mode. And

[0009]

In order to achieve the above object, a slot machine according to a first aspect of the present invention comprises:
The game can be started by setting the number of bets on the game, and the display result of the variable display device is derived and displayed, thereby ending one game, and a predetermined value is determined according to the display result of the variable display device. In a slot machine in which a prize can be generated, stop operation means capable of deriving and displaying a display result of the variable display device by a player's operation, and two kinds of predetermined display results of the variable display device A game state transition means for enabling the game state to be shifted to the special game state when any of the above special prize modes is achieved, and a predetermined period from the occurrence of the special prize mode Up to three types of games with different degrees of advantage are prepared, and for each type of special winning mode derived and displayed as a display result of the variable display device, Probabilities of which degree of advantage will be obtained according to the class are set, and the special game having a high probability of a game having a high degree of advantage until a predetermined period from the occurrence of the special prize mode is set. The prize mode is characterized in that there is a high probability that a game from the occurrence of the special prize mode to a predetermined period has a lower degree of advantage than other special prize modes.

[0010] In the slot machine according to the first aspect, the player can select his or her preference as to whether the game should be a high-risk high-return or a low-risk low-return. Can be improved. Further, the selection of the high-risk high return and the low-risk low return is performed simply by selecting the display result by operating the stop operation means, so that anyone can relatively easily perform the selection.

[0011] In the slot machine according to the first aspect, no matter what kind of special prize mode is displayed on the variable display device, a game from a special prize mode to a predetermined period of time is generated. The expected value of the advantage at is
Preferably, they are substantially the same.

Thus, there is no advantage or disadvantage as a whole depending on the prize mode selected by the player, and the player may select so as to proceed with the game in a type he or she prefers.

[0013] In order to achieve the above object, the slot machine according to the second aspect of the present invention can start a game by setting the number of bets on one game, and can display the display result of the variable display device. Is derived and displayed, one game ends, and in a slot machine capable of generating a predetermined prize according to the display result of the variable display device, it is determined in advance whether or not to allow the generation of the prize. Deciding means, and a game state transition means for enabling a game state to be shifted to a special game state when a display result of the variable display device has a predetermined special winning mode, There are three or more types of games having different degrees of advantage prepared from the occurrence of the prize mode to the predetermined period, and the special prize mode is permitted by the predetermined means. For each game process from the execution of the special prize mode to the occurrence of the special prize mode, a probability of which advantage is to be obtained according to the game process is set, and the special prize mode is generated. The game process in which the probability that the game from the last to the predetermined period has a high degree of advantage is high, and the game from the occurrence of the special winning mode to the predetermined period has a lower degree of advantage compared to the other game processes. It is characterized by a high probability of becoming

In the slot machine according to the second aspect, the player can select whether the game is a high-risk high-return game or a low-risk low-return game according to his / her own preference. Can be improved.

In the slot machine according to the second aspect, even if the special prize mode is generated in any of the game processes after the prize in the special game state is permitted, the special prize mode is generated. It is preferable that the expected value of the degree of advantage in the game from the start to the predetermined period is substantially the same.

[0016] Thus, there is no advantage or disadvantage as a whole due to the game process selected by the player, and the player may select so as to proceed with the game in a type he or she prefers.

[0017] The slot machine according to the second aspect may further include a notifying means for notifying that the special winning mode is permitted by the pre-determining means.

The game device may further include a specific game state generating unit that generates a specific game state that is more advantageous than a normal game. In this case, the game from the occurrence of the special prize mode to the predetermined period of time means that the specific game state generated at the timing related to the end of the special game state which is shifted according to the occurrence of the special prize mode ends. The specific game state can be prepared in three or more types with different degrees of advantage.

In the slot machine provided with these two specific game state generating means, the specific game state generating means may not generate the specific game state with a predetermined probability. In this case, the game from the occurrence of the special prize mode to the predetermined period when the specific game state generating means does not generate the specific game state is a special game that shifts with the occurrence of the special prize mode. The specific game state having the lowest degree of advantage may be a case where the specific game state generating means does not generate the specific game state.

In these cases, it is possible to make it easy to understand the difference in advantage depending on the type of the special game state or the specific game state. Further, in the apparatus provided with the specific game state generating means, the specific game state is not generated. The specific game state having the lowest advantage can be easily understood.

In the slot machine according to the first or second aspect, the game from the occurrence of the special prize mode to a predetermined period is defined as a normal game state after the occurrence of the special prize mode. The period until the state can be set.

In this case, the difference in the game until the normal game state is reached, so that the difference in the advantage of the game up to the predetermined period can be easily understood.

In the slot machine according to the first and second aspects, the special game state can be a big bonus. That is, in the slot machine in which the big bonus is provided as the special game state, when the winning mode of the big bonus occurs, the degree of advantage up to the predetermined period changes.

That is, the big bonus is a gaming state in which the expected value of obtaining a value (medal) for the player is highest. By making the change of the advantage appear in such a big bonus, the interest of the game can be improved.

In the slot machine according to the first and second aspects, the game from the occurrence of the special prize mode to a predetermined period is different in the type of the advantage depending on the difference in the maximum duration. can do.

[0029] Further, the game from the occurrence of the special prize mode to the predetermined period may be such that the type of the advantage is distinguished by the number of valuable values obtainable by the player during the period. .

Alternatively, in a slot machine further comprising a pre-determining means for pre-determining whether or not the occurrence of the prize is allowed, the game from the occurrence of the special prize mode to a predetermined period is determined by the predetermined Advantages may be distinguished based on the probability of winning by means.

Further, the types of the advantages of the game from the occurrence of the special winning mode to the predetermined period are distinguished by the number of valuable values given to the player with the occurrence of the winning for each game. It can also be.

With any of these, it becomes possible to clearly distinguish the difference in the advantage of the game. Here, when the type of the advantage is distinguished according to the number of valuable values given to the player in accordance with the occurrence of the prize for each game, the method itself in which the player proceeds with the game does not change. It can be.

It becomes possible to win a winning combination on an active line set according to the bet amount of the variable display device 2. At the time of winning, medals are paid out, and the gaming state is changed with the winning. Hereinafter, the "roles" determined to be winning will be described.

On the activated line corresponding to the number of bets, for example, “B
When three "ARs" are aligned, the gaming state shifts to the regular bonus. The regular bonus is a game called a regular bonus game a predetermined number of times (for example, 12 games).
), Or by winning a predetermined number of times (for example, eight times) (“JAC” is aligned on the active line). The game control board 101 is provided with a counter for counting the number of regular bonus games and the number of winnings. In addition, the state shifted to the regular bonus, that is, the gaming state in which the regular bonus game is provided is called a first special gaming state,
A regular bonus flag is set in the RAM 112 in the game control board 101.

When, for example, three “colored 7” or three “colorless 7” are arranged on the activated line according to the bet number, the gaming state shifts to the big bonus. In the big bonus, a maximum of 30 games called small combination games can be played. In this small role game, “JAC” is aligned on the active line with a relatively high probability (JA
CIN) and JACIN provide the regular bonus described above (up to three times).

The big bonus ends when the 30 small role games end or when the third regular bonus based on JACIN ends. The game control board 101 is provided with a counter for counting the number of small role games, the number of JACINs, the number of regular bonus games and their winnings, and the number of medals obtained during the big bonus. Note that the state in which the game has shifted to the big bonus is referred to as a second special game state, and the big bonus flag is set in the RAM 112 in the game control board 101.

Also, in a game other than the regular bonus game (including a case provided during the big bonus),
If "watermelon", "cherry" or "bell" is completed, a small portion wins. Also, “colorless 7-watermelon-watermelon”, “colored 7-watermelon-watermelon” or “BA
In the case of "R-watermelon-watermelon", a small portion wins. These small wins will not be won in the internal lottery.

Furthermore, except for the small winning combination game provided during the big bonus period and the regular bonus game, when "JAC" is arranged on the activated line, a replay winning is achieved. In the case where a prize is won in the above-described role, a number of medals corresponding to each role are paid out (except in the case of a replay prize). The corresponding number of credits are stored as data). The number of payouts is
Except for 8 small wins by “watermelon” alone and 4 small wins by “cherry”, there are 15 prints.

Also, in this slot machine 1,
When the big bonus ends, a big bonus end command is sent from the game control unit 101 to the effect control unit 102. Upon receiving the bonus end command, the CPU 121 of the effect control board 102 uses the random number generation function to execute A
By performing T lottery and setting an AT flag in the RAM 112 according to the result, the gaming state is shifted to AT.

The game state of the AT ends when the number of games reaches a predetermined number. The number of AT continuous games is 0 (lost), 100 (lost) according to the AT lottery table shown in FIG. 7, the value of the random number acquired at the time of the AT lottery, and the type of the symbol at the time of winning the big bonus that ends when the AT occurs. And 250. That is, when the big bonus won with “No color 7” ends, 2
An AT of up to 100 games occurs with a probability of 1/100. On the other hand, when the big bonus won with “colored 7” ends, AT of 250 games at maximum occurs with a probability of 1/5.

When the game state of AT occurs, “No color 7
-Watermelon-watermelon "," colored 7-watermelon-watermelon ",
Alternatively, when the small combination of “BAR-watermelon-watermelon” has been won, the type is notified by turning on the small combination notification units 37 to 39. The game state of the AT ends when the number of games reaches the determined AT continuous game number, or when the big bonus winning flag is set and a command indicating that is received from the game control unit 101.

Hereinafter, a gaming operation in the slot machine 1 according to this embodiment will be described. In the following description, the term “game” includes a series of steps from setting the bet number to rotating / stopping the reels 3L, 3C, 3R. Furthermore, reel 3
If any processing (for example, payout of medals or transition of the game state) is performed after the rotation of L, 3C, or 3R is stopped, this processing is also included as processing in one game.

FIG. 8 shows the CPU 11 of the game control board 101.
3 is a flowchart showing processing for one game executed by 1. When the processing of one game is started, first, an initial processing is performed (step S1). If the game is normally in progress, nothing is performed as the initial processing. That is, this initialization process checks the settings and restores the backed up information when the power is turned on or when the system recovers from an error.

Next, the single BET button 14 or MAX
A bet amount is set by operating the BET button 15 or by inserting a medal through the medal insertion slot 13, and a BET process for instructing a substantial start of the game by operating the start lever 11 is performed ( Step S2).

When the number of bets is set by the BET process and the start lever 11 is operated, a lottery process is performed to determine whether or not a winning in each of the above combinations is permitted (step S3). Based on the lottery result in the lottery process, various winning flag commands are set in the RAM 112, and a winning status notification command indicating the winning status of each role is sent to the effect control board 102. The details of the lottery process will be described later.

When the lottery process is completed, a reel change start process is performed next (step S4). In the reel fluctuation start processing, the reels 3L, 3C, and 3R are rotated on the condition that a predetermined time (for example, 4.1 seconds) has elapsed since the start of rotation of the reels 3L, 3C, and 3R in the previous game. Drive the motors 3ML, 3MC, 3MR,
The rotation of all the middle and right reels 3L, 3C and 3R is started. Thereby, the symbol is variably displayed on the variable display device 2. If the predetermined time has not elapsed since the start of the rotation in the previous game, the rotation start is waited, and the weight display unit 31 notifies the weight display unit 31 by lighting the weight lamp 61. The order in which the reels 3L, 3C, 3R are started to rotate may be changed according to the state of various flags set in the RAM 112. At the start of rotation, the timer of the reel stop timer and the timer of one game timer for the next game are started.

Thereafter, reel fluctuation stop processing is performed (step S5). In the reel fluctuation stop processing, after a predetermined condition (detecting the reference position by the reel sensors 3SL, 3SC, 3SR after the rotation speed reaches a certain speed) from the start of rotation of the reel is established, the stop button 12L,
12C and 12R are set to be operation-enabled, and are operated by the respective players, so that the reel motors 3ML and 3M are operated.
The drive of C and 3MR is stopped, and the rotation of the reels 3L, 3C and 3R is stopped. At this time, based on the various winning flags set in the RAM 112 and the game state, the reel 3
The stop symbol is selected by the pull-in control for controlling the drive stop of L, 3C, and 3R. Further, when the time measured by the reel stop timer elapses a predetermined time (for example, 30 seconds), the driving of the reels 3L, 3C, and 3R is forcibly stopped.

When the driving of the reels 3L, 3C, and 3R is stopped, in the display mode at the time of the stop, any of the above-mentioned winning symbols are aligned on the activated line corresponding to the bet number set in the BET processing in step S2. Winning determination processing is performed to determine whether or not the game has been completed (step S6). If it is determined in this winning determination process that one of the winning combinations has been won, various settings corresponding to the type of winning are performed on the game control board 101, and a winning information command is sent to the effect control board 102. When the big bonus ends, a big bonus end command is sent to the effect control board 102. The details of the winning determination process will be described later.

When the winning determination process is completed, a payout process is performed, and the credit is increased by the number of expected payout medals set in step S204. However, when the number of credits stored as data reaches 50, by driving the hopper motor 82,
The excess medals are paid out from the medal payout opening 71 (step S7). Then, the processing for one game ends, and the processing for the next one game starts. If the number of tokens to be paid out has not been set in step S204, no processing is performed as the medal payout processing.

Next, the lottery process in step S3 will be described in detail. FIG. 9 is a flowchart showing in detail the lottery process executed by the CPU 111 in step S3.

First, the random number generated by the random number generation circuit 115 is sampled and acquired by the sampling circuit 116, and the obtained random number value is temporarily stored in the RAM 112 (step S101). Next, a start operation notification command indicating that the start lever 11 has been operated is transmitted to the RA.
M112 is temporarily set in a predetermined area (step S10
2). Then, the set start operation notification command is
The information is transmitted from the I / O port 114 to the effect control board 102 (step S103).

Next, the random number temporarily stored in the RAM 112 in step S101 is set to the probability setting by the setting switch 91, the number of bets set in the BET processing in step S2, and the current game state (normal, during big bonus, regular bonus). It is compared with a winning determination table corresponding to (middle) (step S104). Then, as a result, it is determined whether or not any of the roles has been won (step S
105). If any of the winning combinations is won, a winning flag corresponding to the winning combination is set in the RAM 112 (step S106), and the process proceeds to step S107. On the other hand, if no winning combination has been won, the process proceeds directly to step S107.

In step S107, a winning status notification command corresponding to the lottery result (no winning or each winning type) is generated and temporarily set in a predetermined area of the RAM 112. Then, the set winning status notification command is sent to the I / O
It is transmitted from port 114 to effect control board 102 (step S108). Then, the lottery process ends.

Next, the winning determination processing in step S6 will be described in detail. FIG. 10 is a flowchart showing in detail the winning determination process executed by the CPU 111 in step S6.

First, the single BET button 14 or MAX
On the line activated according to the number of bets set by the operation of the BET button 15 or the insertion of medals from the medal insertion slot 13, the winning flag is set in the RAM 112 by an internal lottery by an internal lottery. It is determined whether or not the symbols are completed (step S201). If none of the symbols of the winning combinations are available, the process proceeds to step S205.

When the symbols of any of the roles are completed, I
A winning information command indicating that the winning combination has been won and a winning line is transmitted to the effect control board 102 via the / O port 114 and the buffer 117 (step S202).
Based on this command, the CPU of the effect control board 102
The 121 controls the light emission of the game effect lamps 75A to 75M and the reel lamp 3LP by controlling the lamp drive circuit 133, for example, and causes the effect to be produced by light and the notification of the winning line. Further, by controlling the speaker drive circuit 131, a winning sound is generated.

Next, various settings are made according to the winning combination. As this setting, for example, when a big bonus is won, the big bonus winning flag is released and the big bonus medium flag is set. Further, when the number of winning games in the big bonus or the regular bonus counted in the game execution processing reaches the number of games to be the end condition, the flag during the big bonus is released. Also, if there is a replay prize, RA
M112 is set to that effect and the replay display unit 32
Is turned on, and the process proceeds to the next process (step S20).
3). However, because of the processing of step S206 described below,
Information indicating that the big bonus in-flight flag has been released is held in a register in the CPU 111 until the processing in step S206 ends.

Further, the number of medals to be paid out is set in the RAM 112 according to the winning combination (step S20).
4). Thereafter, the process proceeds to step S205. In the next step S205, it is determined whether or not the big bonus has ended, that is, whether or not the big bonus in-flight flag has been released in the immediately preceding step S203 and the information to that effect is retained. If the big bonus has not ended, the winning determination processing ends.

When the big bonus is over,
A big bonus end command indicating that the big bonus has ended is transmitted to the effect control board via the I / O port 114 and the buffer 117 (step S206).
Thereafter, based on this big bonus end command, an AT lottery, which will be described later, is performed on the effect control board 102 side, and waits for a time until the effect ends (step S2).
07), the winning determination process ends.

In the repetition of the above game,
The CPU 111 of the game control board 101 shifts the game state between a normal game state, a regular bonus, and a big bonus. On the other hand, the CPU 121 of the effect control board 102 generates the AT gaming state with a predetermined probability by a unique process at a timing related to the end of the big bonus. The probability that an AT gaming state will occur and the number of AT continuous games are determined by whether the big bonus for the end is “colored 7” or “colorless 7”. Hereinafter, processing on the effect control board 102 side related to the occurrence of the gaming state of the AT will be described.

FIG. 11 shows the CPU 1 of the effect control board 102.
22 is a flowchart illustrating a command receiving process executed by a command receiving unit 22. On the effect control board 102 side, the game control board 10
It is determined whether or not a command sent from No. 1 has been received (step S301). Until the command is received, the process of step S301 is repeated, and the command is in a standby state.

When any command is received from the game control board 101, the type of the received command is determined (step S302). If the type of the received command is the winning information command sent in step S202, a winning process described later is executed (step S303). After the prize-winning processing is completed, step S
It returns to the process of 301. If the type of the received command is the big bonus end command sent in step S206, an AT lottery process described later is executed (step S304). After the end of the AT lottery process, the process returns to step S301.

If the type of the received command is step S10
In the case of the winning status notification command sent in step 8,
A small part notification process described below is executed (step S30).
5). After the small role notification process ends, the process returns to step S301. When the type of the received command is another command, a process corresponding to the type of each command (the details are omitted because it is not related to the present invention) is executed (step S306). After that, the process returns to step S301.

FIG. 12 is a flowchart showing the details of the winning process in step S303. At the time of winning,
First, it is determined whether or not a big bonus has been won based on the received winning information command (step S40).
1). When the big bonus is won, the winning symbol information indicating whether the winning symbol is “colorless 7” or “colored 7” is set in the RAM 122 (step S4).
02).

Thereafter, based on the received winning information command, for example, by controlling the lamp driving circuit 133, the light emitting control of the game effect lamps 75A to 75M and the reel lamp 3LP is performed, and the effect by light and the notification of the winning line are notified. Let it do. Further, by controlling the speaker drive circuit 131, an effect corresponding to the winning of the big bonus, such as generating a winning sound, is performed (step S40).
3). Then, the process of this flowchart ends.

On the other hand, if the big bonus has not been won, the game effect lamps 75A to 75M are controlled by controlling the lamp drive circuit 133 based on the received winning information command, as in the case of the big bonus. And the light emission control of the reel lamp 3LP is performed, and the effect by the light and the notification of the winning line are performed. Also, the speaker driving circuit 1
An effect corresponding to the winning combination, such as generating a winning sound, is performed by controlling S31 (step S40).
4). Then, the process of this flowchart ends.

FIG. 13 is a flowchart showing the details of the AT lottery process in step S304. In the AT lottery process, first, the bonus flag is cleared (step S
501). Then, using the random number generation function, 0-9
A random number is generated in the range of 9 and the value of the generated random number is obtained (step S502). Further, at the time of winning the big bonus, the winning symbol information set in the RAM 122 in step S402 is obtained (step S503).

Next, referring to the AT lottery table shown in FIG. 7 based on the obtained random number value and the winning symbol information, A
The value of the number of T-continuation games is acquired (step S504).
If the value of the acquired number of AT continuous games is “0”, it indicates a loss. And the acquired A
Based on the value of the number of T continuous games, it is determined whether or not an AT lottery is won and an AT gaming state is generated, that is, whether or not the acquired value of the number of continuous AT games is other than 0 (step S505). .

If the acquired value of the number of AT continuous games is other than 0 and the AT lottery is won, the AT flag is set to R
It is set to AM 122 (step S506). further,
The liquid crystal display 4 informs the player of the occurrence of the AT gaming state and the number of AT continuing games on the liquid crystal display 4 (step S).
507). Then, the process of this flowchart ends. On the other hand, when the player loses the AT lottery, the player loses the AT lottery and displays on the liquid crystal display 4 that the game mode returns to the normal game state to notify the player (step S508). Then, the process of this flowchart ends.

FIG. 14 is a flow chart showing the details of the small portion notification process in step S305. In the small role notification processing, first, the A in which the AT-in-progress flag is set in the RAM 122 is set.
It is determined whether or not the game state of T has occurred (step S601). If the gaming state of the AT has not occurred, the processing of this flowchart ends. Next, the contents of the received winning status notification command are checked, and it is determined whether or not the winning small combination to be notified has been won (step S602). If the small combination that has been notified has not been won, the process of this flowchart ends. If any of the small wins to be notified has been won, the small notification lamps 67 to 67 corresponding to the small win.
69 is lit, and the winning combination of the small role is notified (step S60).
3). Then, the process of this flowchart ends.

As described above, in the slot machine according to the present embodiment, when the big bonus won with the symbol “colorless 7” ends, the AT of up to 100 games is generated with a half probability. Will be done. When the big bonus won with the "colored 7" symbol ends,
The AT of a maximum of 250 games is generated with a probability of 1/5. Here, the stop button 1 determines whether the big bonus winning symbol is “colorless 7” or “colored 7”.
The player can make a selection by operating 2L, 12C, and 12R.

As described above, in the big bonus of “colored 7”, the probability that the AT of the maximum 250 games having the highest degree of advantage will occur at the timing related to the end (one fifth)
However, it is higher than the probability (0) that an AT of a maximum of 250 games occurs with the big bonus of “colorless 7”. However, in the "colored 7" big bonus, AT
Is not higher (4/5) than the probability (1/2) of the big bonus of "colorless 7". That is,
With the "colored 7" big bonus, it is expected that a large return is obtained although the risk is large, and with the "colorless 7" big bonus, the risk is reduced although the return is small. For this reason, the player can proceed with the game according to his / her preference, depending on which symbol is used to win the big bonus.

Here, as a game after the big bonus,
Whether the high risk high return or the low risk low return is selected depends only on the selection of the symbol by operating the stop buttons 12L, 12C, and 12R. For this reason, even if it is not a very skilled player, any one who likes himself can be easily selected.

The expected value of the number of AT continuous games generated at the timing related to the end of the big bonus of “colorless 7” or the big bonus of “colored 7” is 50 times. It is. The game of the big bonus itself proceeds under exactly the same conditions. In any case, the expected value of the number of AT continuous games for one big bonus is 5
Since it is the same at 0 times, the advantage from the start of the big bonus to the end of the AT can be the same as a whole, regardless of which symbol the player selects the big bonus.

The high risk high return or the low risk low return is determined when the big bonus is won, but since the big bonus is a gaming state in which the player can expect to obtain the most medals, It can improve the interest of the people. Further, since the difference in the number of AT continuous games determines the difference in the degree of advantage, the difference in the degree of advantage is easy to understand, and particularly when the AT does not occur, the case with the lowest advantage is easy to understand.

[Second Embodiment] The configuration of a slot machine 1 according to this embodiment is the same as that of the first embodiment. The processing performed on the game control board 101 side is the same, but the processing performed on the effect control board 102 is different from that of the first embodiment. More specifically, the distribution of the AT winning probability and the number of AT continuing games is performed based on the number of games from the setting of the big bonus winning flag to the actual winning (hereinafter, referred to as the required number of games). An AT lottery table different from that of the first embodiment is prepared.

FIG. 15 is a diagram showing A applied to this embodiment.
It is a figure showing a T lottery table. According to this AT lottery table, the value of the random number acquired at the time of the AT lottery and the AT
0 (losing), 100 according to the number of required games from winning the big bonus that ends at the time of occurrence until winning.
And 250. In other words, when the big bonus that has been won within the required number of games of 9 is completed, the probability of the AT of a maximum of 100 games is reduced by a half.
Occurs. On the other hand, when the big bonus that has been won in the required number of games of 10 or more ends, AT of a maximum of 250 games occurs with a probability of 1/5.

Hereinafter, processing on the effect control board 102 side in the slot machine 1 according to this embodiment will be described.

The CPU 121 of the effect control board 102 performs a command receiving process as in the first embodiment. However, in the command receiving process in this embodiment, when the type of the received command is the winning status notification command, the required game number setting process is performed following the small portion notification process in step S305. Further, the AT lottery process performed at the end of the big bonus is different from that of the first embodiment.

FIG. 16 is a flowchart showing the required game number setting process. In the required game number setting process, first, it is determined whether or not a big bonus has been won based on the received winning status notification command (step S701). If the big bonus has not been won, the processing of this flowchart ends. On the other hand, when the big bonus has been won, the variable indicating the required number of games set in the RAM 122 is incremented by 1 (step S702). Then, the process of this flowchart ends.

It is to be noted that the big bonus winning flag is carried over to the next game if no winning is made. If a big bonus is won, the big bonus winning flag is cleared. For this reason, when a game in which the big bonus winning flag is set occurs, by adding one at a time, it is possible to count the correct number of required games from when the big bonus winning flag is set to when the game actually wins. It has become. Note that the variable indicating the required number of games is cleared at the end of the big bonus in the following AT lottery processing.

FIG. 17 is a flowchart showing an AT lottery process executed by CPU 121 of effect control board 102 in this embodiment. Also in the AT lottery process of this embodiment, first, the bonus flag is cleared (step S801), and a random number is obtained by the random number generation function (step S802). Next, the value of the required number of games set in the RAM 122 by the required number of games setting process performed until the big bonus ending here is won (step S803).

Next, referring to the AT lottery table shown in FIG. 15 based on the obtained random number value and the required number of games,
The value of the number of AT continuous games is acquired (step S80)
4). After that, the processing in steps S805 to S808 is the same as the processing in steps S505 to S508 described above, but the AT is performed in step S807 or S808.
After the notification of the lottery result, the process proceeds to step S809 without terminating the AT lottery process. Then, in step S809, the value of the required number of games set in the RAM 122 is cleared, and the processing of this flowchart ends.

As described above, in the slot machine of this embodiment, if the number of required games is within nine and the big bonus that has been won is completed, an AT of up to 100 games is generated with a half probability. It will be. When the required bonus game is completed with the required number of games of 10 or more, the AT of the maximum 250 games is generated with a probability of 1/5. Here, even if the big bonus winning flag is set, the player can use the stop buttons 12L and 12L.
By the operation of C and 12R (especially the operation of 12L), it is possible to prevent a big bonus from being won.

In other words, in the case of a big bonus having the required number of games of 10 or more, the probability (1/5) that the AT of a maximum of 250 games having a high degree of advantage will occur at the timing related to the end thereof is determined by the required number of games. It is higher than the probability (0) that an AT of a maximum of 250 games will occur with a big bonus won within nine. However, when the number of required games is 10 or more, the probability that the AT with the lowest advantage is not generated (4/5) is also higher than the probability (1/2) of the big bonus where the required number of games is 9 or less. .

Therefore, also in the slot machine 1 according to this embodiment, the player can arbitrarily select either the high-risk high return or the low-risk low return by changing the game progressing method. On the left reel 3L, "colorless 7" and "colored 7" are separated from each other by a maximum of 14 frames. Can be performed relatively easily. Further, the advantage from the start of the big bonus to the end of the AT can be made the same as a whole, which is the same as that of the first embodiment.

[Modifications of Embodiment] The present invention is not limited to the above-described first and second embodiments, and various modifications and applications are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.

In the second embodiment, the number of games from the setting of the big bonus winning flag to the actual winning is set as the required number of games. However, the setting of the big bonus winning flag is not something that the player can know from outside. Therefore, the number of games from the time when the big bonus winning flag is set and the bonus is notified from the bonus notification unit 36 to the time when the big bonus is actually won may be counted as the required number of games. In addition,
In this case, since the required number of games is 0 and a big bonus may be won, the case where the required number of games is 0 may be included in the AT lottery table. This allows the player to more easily proceed with the game in a manner that he / she prefers.

In the first and second embodiments, when a big bonus is won, the game state of the AT does not occur at the timing related to the end of the big bonus,
00 game AT occurs or up to 250 games A
There are three types of game advantages as to whether T occurs. However, for example, up to a further 500
The advantage of the game from the big bonus prize to the predetermined period is 4
There may be more than a street. Even when there are four or more types of advantages, the expected value of the advantage can be made the same regardless of which symbol is won.

In the first and second embodiments, when a big bonus is won, the advantage of the game is distinguished by the presence or absence of an AT at the timing related to the end and the number of the continuous games. Had gone. However, the distinction of the advantage of the game in a predetermined period after winning the big bonus is not limited to this, and may be, for example, the following distinction.

(1) It is assumed that the game state of the AT always occurs at the timing related to the end of the big bonus, and three or more AT continuous games are provided. For example, one of the AT of up to 50 games, the AT of up to 100 games, and the AT of up to 250 games may be generated at a timing related to the end of the big bonus. In this case, in the prize of “colorless 7”, an AT of up to 250 games occurs with a probability of 1/10, an AT of up to 100 games occurs with a probability of 3/5, and a probability of 3/10. , A maximum of 50 game ATs are generated, and in the "colored 7" prize, a maximum of 250 game ATs are generated with a 1/5 probability, and a maximum of 100 game ATs are generated with a 1/5 probability. Alternatively, a maximum of 50 game ATs may be generated with a probability of 3/5. In this way, the advantage is distinguished according to the difference in the number of AT continuous games, so that the player can easily understand the difference in the advantage from the big bonus winning until the end of the AT.
