BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine which displays a plurality of symbols (symbols) while moving them by a predetermined number and stops the display (hereinafter referred to as variable display) in response to a stop operation by a player. The present invention relates to a control device thereof, and particularly to a gaming machine suitable as a slot machine for controlling a variable display operation by a microcomputer or the like and a control device thereof.

[0002]

2. Description of the Related Art As represented by a slot machine, a plurality of kinds of aligned symbol marks (symbols) are moved and stopped in accordance with a player's operation so that the player can aim for the stopped symbol mark. Gaming machines have been loved for a long time. In addition, when the stopped symbol mark corresponds to a specific combination of winning symbols, a substitute coin called a medal, coin, or token (hereinafter collectively referred to as a game medal) is paid out. In, control of moving the symbol mark and various visible and audible outputs are controlled by a microcomputer,
Those that enhance the game effect (so-called pachislot etc.) are often used.

In this type of gaming machine, a plurality of types of symbol marks are arranged at equal intervals on the outer peripheral surface of a plurality of coaxially arranged reels (revolving drums), and the reels are rotated by a player's start operation. , The rotation of each reel is stopped according to the stop operation of the player. Then, if the symbol mark stopped on the pay line in the display window is a combination of specific winning symbols, a game medal or the like corresponding to the symbol combination is paid out (payout).

Specifically, for example, when a player operates a stop button for stopping the variable display operation for each column, the control device responds to a stop command signal generated by the stop button operation by the player. , The variable display operation is stopped within a predetermined time from the generation of the stop command signal for each column. At this time, the control device, depending on the result of the predetermined lottery performed at the time of the start operation and the stop operation of the player, for example, the winning line within the stop time (currently 190 msec in Japan) defined by law. It is determined which one of the symbol marks that can reach the top (which frame) is stopped, the reel is continued to rotate so that the symbol mark is stopped on the winning line, and then the reel is stopped.

Explaining the lottery process, the control device, when a player's start operation is performed, has a plurality of different probability tables corresponding to each of a general game state, a bonus internal winning state, and a bonus game state. Are stored in the memory, and a plurality of lottery winning combinations that can be drawn and their winning probabilities are specified by these probability tables. Then, based on the probability table corresponding to the current gaming state, a predetermined lottery process is executed to determine whether or not it is an internal hit, and when it is an internal hit, the pattern corresponding to the internal hit can be stopped for each reel If the player performs a stop operation in a wide rotation range, the reel rotation control is executed so as to draw the design onto the pay line.

Usually, for a winning combination such as a so-called small winning combination such as cherry or bell, a lottery process is performed at the start of the game, and even if an internal winning is achieved, the player's stop operation wins on the effective line. If it is done at a timing when the design cannot be drawn in, the internal hits will disappear at the same time as the game ends. In other words, the internal win established in this game will disappear unless a prize is won in this game.

However, in the case of a specific winning combination that gives a relatively large amount of profit to the player, for example, a winning combination such as a big bonus or a regular bonus (hereinafter referred to as a bonus combination), the internal winning probability is low because the payout amount is large. It is suppressed. Therefore, as in the case of a small role, the internal win disappears, which is too harsh for the player who invested a lot and allocated the internal hit.

Therefore, only for the internal winning of the bonus role,
A gaming machine has been developed which is configured to hold an internal hit state until a prize is won. In such a gaming machine, it is possible to play the game from the occurrence of the internal win to the actual winning according to the skill of the player with a margin.

[0009]

However, as described above, even in the gaming machine that holds the internal winning state only until the internal winning of the bonus combination until the winning, the bonus internal winning state is exclusively used during the internal winning of the bonus winning combination. The probability table is used, and in the case of the lottery in the internal winning state of the bonus combination, the small combination lottery is performed but the bonus combination lottery is not performed. Therefore, in the internal win state where the big bonus or regular bonus is won, the bonus role is not drawn unless the player performs an effective stop operation within the rotation range in which the specific pattern corresponding to the internal bonus can be stopped. In other words, in other words, the lottery which is disadvantageous to the player is repeated, and the beginner cannot fully enjoy the game.

Further, there is a problem that a large memory area in the ROM must be secured as a plurality of different probability tables corresponding to each of the general game state, the bonus winning internal winning state, and the bonus game state.

The present invention has been made in view of the above conventional problems, and provides a gaming machine in which even a beginner can fully enjoy the game, regardless of the skill of the player. The present invention provides a gaming machine with a reduced memory area for probability table.

[0012]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a variable display device capable of moving and displaying a plurality of patterns and stopping them on a predetermined effective line, and moving by a player's operation.

In order to associate the rotation positions of 32C to 32C with the respective symbol marks m, in the symbol mark table stored in the ROM 52, the rotation position at which a predetermined reset pulse is generated is used as a reference for each fixed rotation angle pitch of the reels 32A to 32C. Is assigned a code number, and a pattern code indicating each symbol mark is associated with each code number. Further, in the winning symbol combination table stored in the ROM 52, the winning symbol combinations, the number of medal payouts in each winning symbol, the winning determination code, and the like are associated with each other during stop control of the reels 32A to 32C. When confirming the winning after stopping all reels,
These are referenced.

Here, considering the features of the present invention, the microcomputer 54 has a game control section 54a, a lottery processing section 54b and a specific internal winning storage section 54c, as shown in FIG. When the lottery processing unit 54b receives a start signal (start signal) from the start switch 61 in each of the general game state, the internal winning state of the bonus combination, and the bonus game state, the lottery processing unit 54b executes a predetermined lottery process described later, It functions as a lottery processing means for determining whether or not a specific internal hit. In addition, the game control unit 54a,
A predetermined number of symbol marks m are moved and displayed in the display windows 31a to 31c according to a predetermined start signal, and the symbol marks m are displayed according to a stop operation of the player.
Function as a display control means to stop the moving display of
When the lottery result of the lottery processing unit 54b is an internal win and the movement display by the reels 32A to 32C is stopped, whether the stopped symbol mark m is a combination of the specific winning symbols corresponding to the internal win Whether or not, that is, a function as a winning determination means for determining whether or not, and a function as a payout control means for paying out a predetermined game medal when the stopped design becomes a combination of the specific winning design Is equipped with.

Further, the lottery processing section 54b has a plurality of lottery probability tables 111, 112, 1 as shown in FIGS.
13, a plurality of lottery combinations and winning probabilities of the lottery combinations are specified. The lottery probability table 111 is used when the number of inserted medals is one, the lottery probability table 112 is used when the number of inserted medals is two, and the lottery probability table 113 is used when the number of inserted medals is three. and Tsu name to be used. These tables 111 to 113 have a big bonus (B
B), regular bonus (RB), watermelon, orange, re-game, 4-cherry, 2-cherry, etc., for each lottery combination, for each set level of the payout rate (for example, 6 levels from 1 to 6) It is the data table which set the lottery data according to the state. The lottery probability is obtained by dividing each lottery data by the fluctuation range of random numbers used in the lottery (for example, 16384). In addition, "general" in the table of each figure
Indicates a general game state, and “inside” means an internal hit state of BB and RB.

Further, in the gaming machine of the present embodiment, a high expectation value gaming state that increases the probability of winning during the general game and a low expectation value gaming state that decreases the probability of winning during the general game are appropriately used. It is designed to be switched, and (High) in the lottery probability table indicates the high expected value gaming state, and (Low) indicates the low expected value gaming state.

By the way, as shown in FIG. 9, the lottery processing section 54b is adapted to use the high-expected-value and low-expected-value lottery probability table portions A used in the normal gaming state even in the internal winning state, The lottery process in the internal winning state of the bonus combination such as BB and RB is executed based on the same probability table portion A as in the normal gaming state. When the lottery result in the internal winning state is further internal win, the lottery result is added as a history to the specific internal hit storage unit 54c (specific internal hit storage means) which is a predetermined lottery history writing area in the RAM 53. And memorize.

That is, two or more specific internal hits can be stored in the specific internal hit storage section 54c by setting two or three specific internal hit flags so that they can be stored. When the winning determination result by the lottery processing unit 54b is a win in the winning state, a predetermined bonus game is executed based on the specific internal winning flag information stored in the specific internal winning storage unit 54c. When the bonus game ends, the number of specific internal hits (the number of valid flags) stored in the specific internal hit storage unit 54c decreases by one, and when there is the remaining specific internal hit, the bonus game ends. After that, the lottery result is changed so as to be different from the general game state.

Specifically, for example, the probability table of the general game after the bonus game state is finished is set to a high expected value, or a certain number of games in the general game immediately after the bonus game state is finished (for example, 1 From the game)) Bonus flag is established (BB, RB inside hits)
Then, the player performs a stop operation so that the bonus symbols are aligned on the pay line, so that the player can enter the bonus game state again (a so-called "continuous chan").

On the other hand, in the big bonus game state, for example, a total of 30 games can be played in the general game. During the general game in the big bonus game state, the lottery processing section 54b uses the lottery probability to be used in the general game state. A lottery probability table portion B different from the table portion A
(The "BB medium general" part of each table) is used, and after winning the big bonus (a specific pattern (for example, "7", "7", "7" after winning the inside) is won. BB and RB will not be re-lotted during the general game (after lining up on the line). Of course, in the general game in big bonus <br/> Sugemu state, BB, to allow a lottery RB, similarly to the above, and stored in a predetermined lottery history write region in the RAM 53 (not shown), there It is also possible to change the lottery conditions after the bonus game state ends based on the stored lottery result.

The game status indicator 14 is the microcomputer 5
It is driven by a lamp drive circuit 75 which receives a display control signal from the display control signal 4, and blinks in a blinking pattern representing each state at the time of winning a prize, continuously operating a character, when a control error occurs, when stopped, when collecting game medals, etc. . In addition, the payout display panel 15 has a high number of medals that can be obtained for a predetermined combination of symbols relating to winning (a combination of the symbol marks m stopped on the effective winning line), a high winning probability, and a high payout rate. A combination of patterns that is in a specific operation state (an operation such as a so-called big bonus or regular bonus) is displayed. The central body panel 16 has a slot machine 1 (not shown).
The name and model number of 0 are displayed. The game medal payout opening 17 below that is a passage for paying out the game pattern dull paid out from the hopper 81 to the tray 18.

Next, the operation will be described.

In the slot machine 10 described above,
The microcomputer 54 executes the following control while fetching signal information from the above-mentioned various switches and sensors, operation information by the player, operation information of each part of the slot machine, etc. according to the control program in the ROM 52.

First, the outline will be described.
In step 4, the random number generated by the random number generator 58 at the start of each game is sampled by the random number sampling circuit 59 at a predetermined timing, for example, when the start switch 61 is actuated, and the random number is used to perform a lottery process described later. Here, when it is determined that the winning is achieved, the internal winning state is set, and the stop command operation signal sent from the reel stop signal circuit 76 by the stop operation of the player draws the pattern corresponding to the winning combination on the winning line. When it occurs within the range, the reels are slid by a predetermined number, and the reels 32A to 32C are stopped so that the winning combination of symbols is obtained. Finally, the presence or absence of a prize is confirmed from the combination of the symbols stopped on each activated pay line, and when the prize is won, the number of medals to be paid out, etc. is displayed on the display 23, and a command signal for paying medals is sent to the hopper. Drive circuit 72
To the payout of medals from the hopper 81.

The specific processing will be described below.
First, when the power is turned on, the microcomputer 54 performs a memory check, initialization of the output port, etc., and then executes the processing shown in FIGS.

First, at the start of processing, the game mode is set to the normal game state, and in step S101, the manual or accumulated medal insertion button 4 is inserted.
A game medal is inserted by the operation of 3a to 43c, or in step S102, a game medal is automatically inserted in the re-game. When the player inserts one game medal into the medal insertion slot 45, only the central pay line L1 is activated, and when two coins are inserted, the upper and lower pay lines L2A and L2B are added to this, and three coins are inserted. Then, all the pay lines L1 to L3 are activated. The activation of the pay lines L1 to L3 at this time is displayed so that the player can visually identify the activation pay line display lamps 21a to 21c, respectively.

Next, in step S103, when the start lever 42 is operated, C is generated in response to a signal (predetermined start signal) from the start switch 61 that detects the operation.
A control signal is sent from the PU 51 to the motor drive circuit 71,
Reels 32A-3 by step motors 35A-35C
2C rotation drive is performed.

Next, at step S104, the lottery processing unit 54
The lottery process is executed by b. At this time, the microcomputer 54 samples random numbers generated by the random number generator 56 by the sampling circuit 59 and extracts random number value data for lottery. Specifically, for example, the count value of a counter that loops at a high speed within a predetermined fluctuation range is extracted when a start signal is input, and the RAM 53 is used as random number data for lottery.
Write in. On the other hand, in the RAM 53, based on the lottery probability tables 111 to 113, numerical range corresponding to each lottery combination and numerical range out of correspondence are assigned within the fluctuation range of the random number corresponding to each lottery combination. The lottery result is specified when the winning request flag or the out-of-range flag is satisfied in the numerical range including the extracted value. Then, if the extractor belongs to the winning area (number range per hit), a winning request signal is generated by setting the winning request flag in the winning request area in the RAM 53, and the out-of-range area (outside numerical range). If it belongs to, the winning request flag in the winning request area is reset.

Now, considering the case where the lottery processing unit 54b generates a big bonus or regular bonus winning request signal to enter the internal winning state, in the internal winning state of the big bonus or the regular bonus, the player's Depending on the stop operation, the regular bonus pattern may be aligned in the big bonus winning state, or the big bonus pattern may be aligned in the regular bonus winning state. In such cases, if conventional
Since the bonus winning lottery is not performed during the internal winning, the game until the bonus winning is a useless game in which the flag lottery is not performed from the viewpoint of performing the bonus lottery, but in the present embodiment, the big bonus Even in the internal winning state of the regular bonus, the lottery process is executed based on the same probability table portion A as the normal gaming state including each bonus winning. Therefore, any one bonus (big bonus or regular bonus)
The result of the lottery in the internal winning state may be the internal winning of another bonus (regular bonus or big bonus). In such a case, the microcomputer 54
Stores the lottery result as a history in the specific internal hit storage unit 54c, in addition to the internal hit for the carry-over.

Then, in step S105, the stop button 4
The operation of pressing 1a to 41c becomes valid, the player presses the stop buttons 41a to 41c, or further, in step S113, a predetermined time (for example, 40
When the automatic stop timer becomes "0" after the lapse of seconds, the rotation of all reels 32A to 32C is stopped.

Next, in step S106, a prize search is performed. That is, when all the reels 32A to 32C are stopped, it is searched whether the combination of the symbol marks m stopped on the activated pay line corresponds to any combination of the winning symbols. With this, if you have won
Either the number of game medals according to the winning content has been won, or the game can be replayed.

Next, in step S107, it is determined whether or not the winning content is a re-play. If the result of the determination is YES, the game proceeds to the re-play. If another win, then the next step S10.
At 8, the number of game medals obtained is added to the number of accumulated medals or is paid out to the tray 18.

Next, in step S109, it is determined whether or not it is a big bonus (BB) prize, and in step S110 it is determined whether or not a regular bonus (RB) prize is received. If it is determined that the bonus is not won, the process returns to step S101.

Now, for example, if it is determined that a prize corresponding to the inside hits has been obtained and it is determined that a big bonus has been won, then a big bonus game as shown in FIG. 11, for example, is played.

First, in step S111, it is determined whether or not the general game has been exhausted 30 times in the big bonus game state, and the processing of the next step and thereafter is executed until all the basic games are exhausted.

At step S112, game medals are inserted,
When the start lever 42 is operated in the next step S113, in response to the start signal from the start switch 61, C
A control signal is sent from the PU 51 to the motor drive circuit 71,
After the reels 32A to 32C are rotationally driven, the lottery process is executed in step S114. At this time, the lottery processing unit 54b uses a lottery probability table portion B different from the lottery probability table portion A used in the normal gaming state, so that BB and RB are not re-lottered. If the lottery combination is a small combination (for example, watermelon, watermelon, watermelon, or bell, bell, bell, etc.), the winning request flag of the corresponding winning request area is set.

Then, in step S115, the stop button 4
The operation of pressing 1a to 41c becomes valid, the player presses the stop buttons 41a to 41c, or further, in step S113, a predetermined time (for example, 40
When the automatic stop timer becomes "0" after the lapse of seconds, the rotation of all reels 32A to 32C is stopped.

Next, in step S116, it is searched whether or not the combination of the symbol marks m stopped on the activated pay line corresponds to any combination of the winning symbols, and then in the next step S117, the number of acquired images is obtained. The game medal of is added to the number of stored medals or is paid out to the tray 18.

Next, in step S118, it is determined whether or not a bonus game is won. If the bonus game is not won, the process returns to step S111, and if 30 normal games have been consumed, the big bonus game state ends. And it returns to the initial general game state.

If it is a bonus prize, the game proceeds to a bonus game that can be played up to 12 games or 8 times, and it is determined in step S121 whether 12 games of the bonus game have been exhausted. The process is repeatedly executed.

At step S122, game medals are inserted,
When the start lever 42 is operated in the next step S123, C is generated in response to the start signal from the start switch 61.
A control signal is sent from the PU 51 to the motor drive circuit 71,
After the reels 32A to 32C are rotationally driven, in a step S124, a predetermined bonus game high probability and high payout lottery process is executed.

Next, in step S125, when the player depresses the stop buttons 41a to 41c, or when the automatic stop timer becomes "0" after a predetermined time (40 seconds, for example) has elapsed from the start of reel rotation, all reels 32A to 32C
Rotation is stopped.

Next, in step S126, it is searched whether or not the combination of the symbol marks m stopped on the activated pay line corresponds to a predetermined combination of winning symbols, and if a prize is won, then in step S127. Number of acquisitions (eg 1
Five (5) game medals are added to the number of stored medals or paid out to the tray 18.

Next, in step S128, it is determined whether or not the player has won eight times in the bonus game. If the player has not won eight times, the process returns to step S121. If the player has won eight times, the present bonus game is ended in step S129, and it is determined in the next step S130 whether or not the big bonus is in operation.
It is determined whether or not the bonus game has been played three times in total. Then, if the bonus game has not been played three times, the game returns to the big bonus game state, and if the bonus game has been played three times, the game returns to the initial general game state.

[0062] By the way, the picture corresponding to hit the inside of the first bonus combination after becoming internally per state of big bonuses and regular turbo <br/> Nasu, a reel stop state corresponding to hit the inside of the other bonus combination Will be awarded and
There is a possibility that the bonus game state after the winning has ended. Therefore, the microcomputer 54, at the start of the general game, for example, in step S101 in which a game medal is inserted,
The lottery result stored in the specific internal hit storage unit 54c is checked, and the lottery condition for the predetermined game thereafter is changed based on the stored information.

For example, the probability table is set to a high expected value at the start of the general game after the bonus game state ends, or the bonus internal winning state is set immediately after the bonus game state ends. Therefore, in the subsequent lottery in step S104, a lottery result advantageous to the player can be obtained.

As described above, in the present embodiment, the game until the bonus is won in the state where the big bonus or the regular bonus is internally won does not become a disadvantageous game in which the bonus combination is not drawn as in the conventional case.

In the above embodiment, when the lottery processing means executes the lottery processing in the profit state of at least one of the internal winning state of the bonus combination and the bonus game state, the probability of the lottery processing in the general gaming state. When a lottery result with a lower bonus lottery probability than the table is used and the lottery result in the profit state is internal win, the lottery result is stored, and a bonus game corresponding to a specific internal win is stored based on the stored lottery result. It is also possible to change the lottery conditions after the state has ended. For example, as shown in FIGS. 13 and 14, in addition to the probability table 133, a lottery probability table portion Ao used in the general gaming state and a lottery probability table portion Co used in the general gaming state in the big bonus game state. , A probability table Bo having a lower bonus lottery probability than the lottery probability table portion Ao is provided, and these are switched and used according to the game state. Specifically, in the probability table Bo with a low bonus lottery probability, for example, the data of the lottery probability table portion Ao in the state of inserting three medals is 52 to 68, whereas the data of the internal winning probability table portion is lottery. The value is about ⅕ of the data in the probability table portion Ao (10 to 14), and the lottery probabilities of small wins are made to be exactly the same.

When the lottery result in the internal bonus state of the big bonus or the regular bonus is the internal bonus of another bonus combination, the lottery result based on the probability table Bo is temporarily stored in the specific internal bonus storage unit 54c, and Similar to the example, the lottery conditions after the bonus game state ends are changed based on the stored lottery result. As a result, when the internal bonus is currently being won, the bonus lottery is certainly performed, but the probability is set to be lower than the lottery data in the general game, so the bonus flag is not elected unnecessarily and the player is Balance the profit with the store.

A lottery with a specific internal win is possible, and the result of this lottery process is a more specific internal hit.
In the case of
In addition, since the lottery processing result is stored, it is possible to solve the problem that a beginner repeats a disadvantageous game in a specific internal winning state, and it is possible to provide a gaming machine in which a game can be fully enjoyed.

Further, if the lottery processing means executes the lottery processing based on the same probability table in both the normal game state and the internal winning state of the bonus combination, the probability table memory area is reduced. You can, and
When a specific winning pattern is gathered in the internal winning state of the bonus combination, the result can be reflected in the subsequent games. As a result, even beginners can fully enjoy the game.

When the lottery processing means executes the lottery processing in at least one profit state of the bonus winning internal winning state and the bonus game state, the bonus lottery probability is lower than the probability table of the lottery processing in the normal gaming state. Even if the probability table is used, when a specific winning pattern is prepared in the internal winning state of the bonus combination, the result can be reflected in the subsequent games.
