Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine, a pachinko machine, and other gaming machines provided with a variable display means for variably displaying symbols necessary for a game, and a control means such as a microcomputer for controlling the variable display. Regarding

[0002]

2. Description of the Related Art For example, a slot machine provided with a stop button, a so-called pachi-slot machine, is a mechanical variation display device or reel in which a plurality of rotary reels for varying display of a plurality of symbols are arranged in a front display window. It has an electric fluctuation display device for displaying the above pattern on the screen. In response to the player's start operation, the control means drives and controls the variable display device to rotate each reel, thereby displaying the symbols in a variable manner, and automatically after a fixed time or by the player's stop operation, each reel. Stop the rotation of. At this time, when the symbols of the reels appearing in the display window form a specific combination (winning symbol), a profit is given to the player by paying out a game medium such as a medal or a coin.

Currently, the mainstream models have a plurality of types of winning modes. In particular, when the winning of a certain winning combination is established, the game state is better than the normal state for a predetermined period of time, instead of ending the payout of medals once. As such a role, a role in which a game that gives a relatively large profit to the player can be played a predetermined number of times (hereinafter referred to as a "big bonus", abbreviated as "BB") and a relatively small profit is given to the player. There is a role in which the game can be played a predetermined number of times (referred to as "regular bonus", and abbreviated as "RB" hereinafter).

In the currently mainstream models, a predetermined combination of symbols is lined up along an activated pay line (hereinafter referred to as "effective line"), and a prize for paying out medals, coins, etc. is established. Indicates the winning combination of the winning combination (hereinafter referred to as "internal winning combination"), which was won by the internal winning process (hereinafter referred to as "internal drawing"). The player is required to perform a stop operation at a timing when the symbol combination can be stopped on the activated line. In other words, no matter how much the internal winning is won, if the timing of the stop operation of the player is wrong, the winning of the internal winning combination cannot be established. That is, a technique for performing the stop operation at a timely timing is required (“push”)
It is said that gaming machines, which are said to have a high degree of technical intervention, are currently the mainstream.

Further, for the purpose of keeping a constant number of games that can be played in a unit game medium bet on a game, it is possible to play the next game without betting the game medium when a prize is established. A gaming machine provided with such a role (hereinafter referred to as "re-game") is the current mainstream. And
There is provided a gaming machine having a function of generating a period (hereinafter referred to as “high-probability replay period”) having a high probability of being internally won in the “replay”.

Further, there has been provided a game machine in which the winning times of BB or RB are biased. In this gaming machine, the number of internal wins in the BB or RB is stored, and the winning of the number of times can be realized. And
Even if the number of times that a “high probability replay period” is generated and the winning of BB or RB can be achieved is “1 or more”, “retraction control” or “kicking control” of replay is prioritized. The winning of BB and RB is not established by giving priority to the "winning control" of the small winning combination. In this way, even if the BB or RB is internally won, the winning combination cannot be realized until after the "high probability replay period" ends, so the BB or R is won.
It is possible to give a bias to the winning timing of B.

[0007]

However, in the gaming machine in which the winning times of the above BB or RB are biased, the number of games in which the "high probability replay period" continues is BB or RB. It is set in consideration of the probability of internal winning. Therefore, the number of times that the winning of the BB or RB can be achieved converges to "0", and the deviation of the generation timing of the BB or RB falls within a certain range, which may be uninteresting. In other words, the number of times that the winning of the BB or the RB can be achieved is often “0” even though the “high probability replay period” has ended. In such a case, the player may lose interest in the game because the winning of the BB or RB cannot be achieved despite the end of the "high probability replay period".

It is an object of the present invention to provide an entertaining gaming machine in which the player does not lose interest in the game.

[0009]

The gaming machine of the present invention is a variable display means (for example, reels 3L, 3C, 3R described later) for variably displaying symbols necessary for the game, and an internal winning for determining an internal winning combination. Role determining means (for example, CPU 31 described later)
Based on the determination result of the internal winning combination determination means and the winning combination of the winning combination (for example, a winning combination (such as BB, RB, etc., in which a gaming situation (state) advantageous to the player is generated when the winning combination is established)), the winning combination is determined. A memory for storing related information (for example, information stored in a bonus stock counter described later, a result of subtracting the number of winnings from the number of internal winnings for an increasing role (the number of bonuses stocked below), etc.) Means (for example, CPU 31 or RAM 33 described later)
And a stop control means (for example, a main control circuit 7 to be described later) for stopping and controlling the variable display of the variable display means based on the determination result of the internal winning combination determination means and the information stored in the storage means.
1) and in a predetermined situation (for example, a high-probability replay period), by stop control of the variable display by the stop control means (for example, a diagram based on the stop control table selected in the process of ST77 of FIG. 18 described later). In the processing of ST23 of 13), the reciprocal of the probability that the internal winning combination determining means determines the internal winning combination as the internal winning combination is not established, and the reciprocal of the number of games in which the predetermined situation continues (for example, It is characterized in that it is smaller than the expected value of (the number of continuous games described later).

In a particular embodiment of the present invention, the given situation is
It is characterized in that there is a high probability of internally winning a predetermined combination (for example, a re-play).

In a particular embodiment of the present invention, the given situation is
When a special game state (for example, a BB game state or an RB game state described later) that occurs due to the winning of the winning combination is completed (for example, when the determination in ST33 of FIG. 14 described later is “YES”) Occurs (for example, a high-probability replay flag described later is set).

In a specific embodiment of the present invention, when the internal winning combination determining means determines a predetermined winning combination as an internal winning combination, the stop control means, in a situation other than a predetermined situation (for example, a normal period described later), So that the winning of a predetermined part is established (for example,
The variable display is controlled to be stopped by using a prize winning stop control table (FIG. 5) which will be described later, so that in a given situation, the probability that a given winning combination is achieved will be equal to a situation other than the given situation. It is characterized in that the variable display is stopped and controlled (based on the processing in ST76 of FIG. 18 based on a re-playing selection table (FIG. 7) described later).

[0013]

In the gaming machine of the present invention, in a predetermined situation, the winning combination of the winning combination is not established by the stop control of the variable display by the stop control means. The reciprocal of the probability that the internal winning combination determining means determines the increasing winning combination as the internal winning combination is smaller than the expected value of the number of games in which the predetermined situation continues. Therefore, by advancing the game, information related to the increasing role,
For example, the number of times that the winning combination of the winning combination can be realized increases, and after the predetermined situation ends, the number of times is rarely “0”, and the winning combination of the winning combination can be realized. Increase. Further, since the determination result of the internal winning combination determining means has little influence on the realization of the winning combination of the increased winning combination, it is possible to arbitrarily set, for example, the occurrence condition and the ending condition of a predetermined situation. The degree of freedom in designing can be increased.

In the embodiment of the present invention, it is possible to adopt, as the predetermined situation, a situation in which there is a high probability of internally winning a predetermined winning combination.

Further, it is possible to generate a predetermined situation when the special game state generated by the establishment of the winning of the increased winning combination is completed.

Further, when the internal winning combination determining means determines the predetermined winning combination as the internal winning combination, the stop control means stops the variable display so that the winning of the predetermined winning combination is established in a situation other than the predetermined situation. In a predetermined situation, the variable display can be stopped and controlled so that the winning probability of the predetermined winning combination is equal to the situation other than the predetermined situation. This allows
It is also possible to prevent the player from knowing whether or not the situation is predetermined.

FIG. 2 shows a symbol row in which 21 symbols of a plurality of types shown on each reel 3L, 3C, 3R are arranged. Code numbers “01” to “21” are attached to each symbol, and a ROM described later as a data table.
32 (FIG. 10). Each reel 3L, 3
On C, 3R, "blue 7 (design 91)", "red 7 (design 92)", "BAR (design 93)", "watermelon (design 9
4) ”,“ Plum (design 95) ”,“ Replay (design 9
6) "and" cherry (symbol 97) "are arranged in the symbol row. Each reel 3L, 3C, 3R
Is rotationally driven so that the symbol row moves in the arrow direction of FIG.

FIG. 3 shows winning combinations and payout numbers corresponding to winning symbol combinations in each gaming state.

Here, in the embodiment, basically, the game states are distinguished according to the types of winning combinations that are likely to win internally. That is, in the games in the same gaming state, the types of winning combinations that may be internally won are the same.
The types of winning combinations that are likely to win internally are determined by a probability lottery table (FIG. 4) described later. However, B
"BB game state" that occurs when B wins
Includes the "general game state in BB" that may be internally won for a small winning combination and the "RB gaming state" that may be internally won as a winning character described below. Including states in which different types of roles are used.

The normal game state, which is the normal game state,
It is divided into a “high probability replay period” and a “normal period”.
In the “high probability replay period”, the probability of internally winning the replay is higher than in the “normal period” (FIG. 4 described later). However, in these two periods, the probability of winning the replay prize is equalized by performing the processing of ST76 of FIG. 18 described later.

In the embodiment, after the bonus is internally won, the bonus is held as an internal winning combination until the bonus is won (generally referred to as "carryover"). Further, even when the bonus is internally won, the bonus is internally won. Specifically, the type of internally won bonus and the order in which the bonus is internally won are stored. Then, in the case where the bonus is internally won a plurality of times without the winning of the winning being achieved, the winning of the bonus of the plurality of times can be realized. More specifically, the gaming machine of the embodiment can store bonuses or store information thereof (hereinafter referred to as “stock”) in a bonus stock counter (FIG. 9) described later.

For example, when the bonus is not internally won, the RB is internally won. Then, the winning of the RB is not realized, and the BB is internally won.
As a result, the winning of BB and RB can be achieved "once". As will be described later, the stocked bonuses can achieve winning in the order in which internal winnings have been won. In this example, the winning of the RB can be achieved after the winning of the BB is achieved.

As shown in FIG. 3, the winning of BB is "red 7-red 7-red 7" or "blue 7-blue 7" in the normal game state.
-Blue 7 "is formed by lining up along the activated line. After the winning of BB is established, the gaming state becomes the general gaming state during BB.

The winning of RB is "BA" in the general game state.
R-BAR-BAR ”should be lined up along the effective line, or B
"Replay-Replay-Replay" in the B general game state
Alternatively, it is established by arranging "BAR-Replay-Replay". The establishment of a winning RB in the BB general game state is generally referred to as "JAC IN". After the winning of the RB is established, the gaming state becomes the RB gaming state.

The prize for the replay is "Replay-Replay-Replay" or "BAR-Replay-Repla" in the normal game state.
It is established by lining up y ”. When the replay winning is established, the same number of medals as the inserted medals are automatically inserted, so that the player can play the next game without consuming the medals. Here, in the "high-probability replay period", when the internal re-game is won, "55425/6553
6 "probability of stop operation by the player (stop button 7L, 7
Regardless of the operation timing of C or 7R or the operation sequence (stop sequence), reel stop control (generally referred to as "kicking control") that fails to win the replay is performed. By this stop control, the probability of winning the replay in the "normal period" and the "high-probability replay period" is equalized.

Also, in the normal game state and the BB general game state, it is possible to realize the winning of the "cherry's small win", "plum's small win", and "watermelon small win". The payout number is as shown.

The prize winning of the character is "Re" in the RB game state.
play-Replay-Replay "or" BAR-Replay-Replay "
Applies by lining up. The winning number of winnings of the character is "8"
The game state changes when it becomes "time". Here, the game in the RB game state in which the winning of a winning character may be achieved is generally referred to as a "JAC game".

The occurrence condition of the "high probability re-play period" is that "the BB game state in the situation where the bonus is stocked, or the RB game state generated by arranging" BAR-BAR-BAR "along the activated line. To end (Fig. 1 below)
After the determination of ST33 of 4 is “YES”, the determination of ST61 of FIG. 17 described later is “YES”), or “internally win the bonus in the normal period (determination of ST53 of FIG. 16 described later). Is “NO”) ”. That is, the "high-probability replay period" occurs only when there is stock. Further, as will be described later, in the "high probability replay period", it is not possible to achieve the winning of the bonus. Therefore, the “high-probability replay period” is a period during which there is always stock. The ending condition of the "high probability re-play period" is that the game for "the number of continuous games (FIG. 8 described later) is ended (the determination in ST48 of FIG. 15 described later is" YE
It must be S ")".

The condition for the occurrence of the "normal period" is that "the high probability replay period ends (the determination in ST48 of FIG. 15 described later is" YES ")" or "the situation in which no bonus is stocked. In BB game state, or "BA
The RB game state generated by arranging "R-BAR-BAR" along the activated line is ended (S in FIG. 17, which will be described later).
The determination of T61 is “NO”) ”. The ending condition of the "normal period" is "the winning of the bonus is established (transition to the BB gaming state or the RB gaming state and the general gaming state is finished)", or "internal winning of the bonus (described later). The determination in ST53 of FIG. 16 must be "YES"). "

Here, in the "high-probability replay period", even if the bonus is stocked, the reel 3
The stop control of L, 3C and 3R prevents the winning of the bonus from being realized. In other words, the condition for winning the bonus is that after the "high probability replay period" ends, the period until the bonus is internally won ("normal period")
Of the stock), the stop buttons 7L, 7C, 7R are operated at a predetermined timing. Among the stocked bonuses, the winning of the first priority bonus is "high probability replay period"
It will be possible after the transition from "to the normal period". The priority order is a priority order of bonuses that have been internally won but have not been won (stocked bonuses) that have been internally won earlier. For example, when the "high probability replay period" shifts to the "normal period", BB
"1" in "Priority"
When the "rank" is RB, the winning of BB can be realized only after the winning of RB is established.

FIG. 4 shows an example of determining the internal winning combination in the normal gaming state when the BET number is "3" (see FIG.
The probability lottery table used in 5) is shown.

FIG. 4 (1) shows a probability lottery table for the normal period. In the probability lottery table shown in FIG. 4 (1),
Random number extraction range in probability lottery process "0" to "16383"
Among them, when a random number within the range of “215” to “2459” is extracted, “replay” becomes an internal winning combination. The probability of internally winning the "replay" is "2245/16384".

FIG. 4B shows a probability lottery table for the high probability replay period. In the probability lottery table shown in FIG. 4B, the random number extraction range “0” in the probability lottery process
When a random number within the range of “215” to “14765” is extracted from “16383”, “replay” is the internal winning combination.
The probability of internally winning the "replay" is "14551/16384".

As described above, in the "high probability replay period", the probability of internally winning the replay is higher than in the "normal period". In the tables shown in FIGS. 4 (1) and 4 (2), the probabilities of internally winning the winning combinations other than "replay" and "none (miss)" are the same. Also, the probability of internally winning the bonus (the probability of internally winning either BB or RB) is “215/16384 (about“ 1 / 76.2 ”)”.

Next, with reference to FIG. 5 and FIG. 6, the stop control table used when the internal game is won in the replay will be described. This stop control table is used in a sliding piece number determination process (ST22 in FIG. 13) described later.

Each reel 3 is included in the "stop control table".
"Stop operation position" and "Stop control position" of L, 3C, 3R
And are shown. “Stop operation position” means each reel 3
Stop buttons 7L provided corresponding to L, 3C and 3R,
The symbols located on the center line 8c when 7C and 7R are operated (specifically, the center of the symbol is located above the center line 8c, and the center thereof is the center line 8c).
It represents the code number of the pattern closest to the position of c).
The "stop control position" represents the code number of the symbol stopped and displayed at the position of the center line 8c when the reel on which the stop operation is performed is stopped. Here, in this embodiment, the so-called "number of sliding frames" is set to "4 frames" at maximum. For example, while the right reel 3R is rotating, when the "blue 7 (symbol 91 in FIG. 2)" of the code number "08" reaches the position of the center line 8c, the stop button 7R
When is operated, the right reel 3R can be stop-controlled so that the "plum (symbol 95 in FIG. 2)" of the code number "12" is stopped and displayed at the position of the center line 8c.

FIG. 5 shows a winning stop control table. This table is always used in a game that is internally won for replay during the "normal period". On the other hand, in the game internally won for the replay in the “high probability replay period”, whether or not to use this table is determined by the process of ST76 in FIG. 18 described later.

In FIG. 5, the "stop control position" of the left reel 3L is code number "02", "05", "0".
It is either 8 "," 13 "or" 18. "In the symbol row shown in Fig. 2, the symbol arranged one below the symbol corresponding to these is" Replay "or" BAR ".

In FIG. 5, the "stop control position" of the central reel 3C is the code number "03", "08",
It is either "12", "16" or "19". In the symbol row shown in FIG. 2, the symbols corresponding to these are
It is "Replay".

In FIG. 5, the "stop control position" of the right reel 3R is code number "01", "05", "1".
It is either 0 ”,“ 14 ”or“ 18. ”In the symbol row shown in FIG. 2, the symbol arranged on one of the symbols corresponding to these is“ Replay ”.

As described above, when the winning stop control table shown in FIG. 5 is used for stopping control of the reels 3L, 3C, 3R, "Replay-Replay-Replay" along the cross-up line 8e. Or "BAR-Replay-Repla
y ”will be lined up, which means that the replay prize will be won.

FIG. 6 shows a stop control table for non-winning prizes. This table determines whether or not to use this table by the process of ST76 of FIG. 18 described later in the game internally won for the replay in the “high probability replay period”. Here, the stop control positions for the stop operation positions of the left reel 3L and the center reel 3C are the same as those shown in FIG.

In FIG. 6, the "stop control position" of the right reel 3R is code number "02", "06", "1".
It is either 1 ”,“ 15 ”or“ 19. ”In the symbol row shown in FIG.
ay ". Further, in the symbol row shown in FIG. 2," Replay "is not arranged above one of the symbols corresponding to these symbols.

As described above, when the stop control table for non-winning prize shown in FIG. 6 is used for stop control of each reel 3L, 3C, 3R, "Replay" is displayed at the lower position in the left display window 4L. "Or" BAR "is stopped and displayed. "Replay" is stopped and displayed at the middle position in the center and right display windows 4C and 4R. That is, when the stop control table for non-winning prize is used for the stop control, the winning of the re-game is not established.

Next, the replay selection table will be described with reference to FIG. This table is for determining whether to use the winning-winning stop control table or the unwinning-winning stop control table in the “high probability replay period”. Specifically, S in FIG.
Used in the processing of T76. In this selection table, the probability of selecting the stop control table for winning a prize is “10111
/ 65536 ”. The probability of selecting the non-win prize stop control table is“ 55425/65536 ”.

Here, as described above (FIG. 4 (2)),
The probability of internally winning the replay in the “high probability replay period” is “14551/16384”. Therefore, the probability of winning the replay in the "high probability replay period" is about "0.1370 (" 14551/16384 "x" 10111/6553 ", considering the probability that the stop control table for winning is selected.
6 ”)”. On the other hand, in the “normal period”, since the winning control stop control table is always used, the probability of internally winning the replay is equal to the probability of winning the prize. That is, the probability of winning the replay game during the “normal period” is about “0.1370 (“ 2245/16384 ”)”. As described above, in the embodiment, the probabilities of winning the replay are equal in the “high-probability replay period” and the “normal period”.

Next, with reference to FIG. 8, a continuation game number selection table for the "high probability replay period" will be described.
This table shows the number of games that the "high probability replay period" continues when the "high probability replay period" occurs, depending on whether the priority "1st" bonus is BB or RB. It is used to determine (hereinafter referred to as “the number of consecutive games”) (to perform the processing of ST62 in FIG. 17 described later). A random number range for winning and a probability that the number of continuous games is selected (hereinafter referred to as “selection probability”) are shown for each number of continuous games. In addition, as described above, the winning of the bonus cannot be realized in the “high-probability replay period”. The ending condition of the "high probability replay period" is "the game for the number of continuous games is finished".

Here, after shifting to the "high-probability replay period", the average value or expected value "G" of the number of games required until the bonus winning is established (until the "high-probability replay period" ends) Is calculated by multiplying the number of continuous games by the selection probability corresponding to the number of continuous games, and adding up the values. In particular,
“G” is obtained by calculating Σ {(number of continued games) × (probability of selection)}. B is the first priority
In the case of B, “G” is about “301.4 times”.
Also, if the priority “first place” is RB,
"G" is about "599.2 times".

By the way, as described above, the probability of internally winning either BB or RB in the general game state is
It is "215/16384 (about" 1 / 76.2 ")". That is,
The expected value of the number of games required to internally win either BB or RB (the reciprocal of the probability of internally winning the bonus) is about “76.2”. On the other hand, as mentioned above,
“G” is about “301.4 times” or about “599.2 times”. In other words, the reciprocal of the probability that the winning combination will be decided as the internal winning combination is
The "high-probability replay period" is smaller than the expected number of continuous games. Therefore, as the number of games increases,
The number of bonuses stocked will increase. That is, the probability of winning the bonus is lower than the probability of internally winning the bonus. From the above, in many cases, after the “high-probability replay period” ends, a bonus prize is established, and the “high-probability replay period” again occurs. Therefore, after the condition for generating the “normal period” is satisfied, the condition for ending the condition (that the bonus winning is satisfied) is satisfied in a short period of time, so that the period of the “normal period” is extremely short.

Next, the bonus stock counter will be described with reference to FIG. This counter stores the priority of bonuses (stocked bonuses) that have been internally won but have not been won. The bonus stock counter is updated by the processing of ST52 of FIG. 16 and the processing of FIG. 19 described later. In addition, the stored information of the bonus having the priority of “first place” is shown in FIG.
Used in the processing of ST61.

9 (1) to 9 (3) are conceptual views of the bonus stock counter. In this counter, the type of internally won bonus (whether it is BB or RB)
Information is stored in association with the priority order. In the situation where the information stored in the bonus stock counter is as shown in FIG. 9 (1), when the BB is internally won, the priority order is "127th" as shown in FIG. 9 (2).
The information indicating BB is stored as the type (type) of the bonus. On the other hand, when the winning of BB is established, FIG.
As shown in (3), the priorities of bonuses whose priority is "second place" and lower are advanced one by one. By using this bonus stock counter, BB or R
The winning of BB or RB can be realized in the order in which B internally wins.

FIG. 10 is a main control circuit 71 for controlling the game processing operation in the gaming machine 1, a peripheral device (actuator) electrically connected to the main control circuit 71, and a control command transmitted from the main control circuit 71. Liquid crystal display device 5 based on
And a sub-control circuit 72 for controlling the speakers 21L and 21R
A circuit configuration including and is shown.

The main control circuit 71 has a microcomputer 30 arranged on a circuit board as a main component, and a circuit for random number sampling is added thereto. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program, a ROM 32 and a RAM 33 that are storage means.

The CPU 31 includes a clock pulse generating circuit 34 for generating a reference clock pulse and a frequency divider 35,
A random number generator 36 for generating random numbers to be sampled and a sampling circuit 37 are connected. As a means for random number sampling, the random number sampling may be performed within the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation. Also, C
The PU 31 has a bonus stock counter.

In the ROM 32 of the microcomputer 30, a probability lottery table used for determination of random number sampling performed each time the start lever 6 is operated (start operation), and a reel stop mode are determined according to the operation of the stop button. A stop control table for storing, various control commands (commands) for transmitting to the sub control circuit 72, and the like are stored. This command includes "Demo Display Command",
There are "all reel stop command" etc. These commands will be described later. The sub control circuit 72 does not input commands, information, etc. to the main control circuit 71.
Communication is performed in one direction from the main control circuit 71 to the sub control circuit 72.

The RAM 33 has a high probability replay flag storage area. The high-probability replay flag is a flag indicating whether or not it is currently in the "high-probability replay period". When the high probability replay flag is set, it is a "high probability replay period". When the high probability replay flag is cleared, it is a "normal period". Note that setting a flag means storing information indicating "1" in the high-probability-replay flag storage area. Further, clearing the flag means storing information indicating "0" in the high-probability-replay flag storage area. Further, the RAM 33 stores the number of continuous games.

In the circuit of FIG. 10, the main actuators whose operation is controlled by the control signal from the microcomputer 30 are various lamps (1-BET lamp 9a, 2-BET lamp 9b, maximum BET lamp 9).
c, hit display lamp 17), various display units (payout display unit 18, credit display unit 19, bonus game information display unit 20), medals are stored, and a predetermined number of medals are paid according to an instruction from the hopper drive circuit 41. A hopper (including a driving unit for paying out) 40 as a game value giving means for giving out
And stepping motors 49L, 49C, 49R for driving the reels 3L, 3C, 3R to rotate.

Further, stepping motors 49L, 49
The motor drive circuit 39 that drives and controls C and 49R, the hopper drive circuit 41 that drives and controls the hopper 40, the lamp drive circuit 45 that drives and controls various lamps, and the display unit drive circuit 48 that drives and controls various display units are I / O. O port 38
It is connected to the output part of the CPU 31 via. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31, and controls the operation of each actuator.

Further, as the main input signal generating means for generating the input signal necessary for the microcomputer 30 to generate the control command, the start switches 6S, 1-B are used.
ET switch 11, 2-BET switch 12, maximum BE
There are a T switch 13, a C / P switch 14, an inserted medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51. These are also I /
It is connected to the CPU 31 via the O port 38.

The start switch 6S detects the operation of the start lever 6. The inserted medal sensor 22S detects a medal inserted into the medal insertion slot 22. The reel stop signal circuit 46 generates a stop signal according to the operation of each stop button 7L, 7C, 7R. Reel position detection circuit 5
0 is a signal for receiving the pulse signal from the reel rotation sensor and detecting the position of each reel 3L, 3C, 3R is C
Supply to PU31. The payout completion signal circuit 51 generates a signal for detecting the completion of medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 40) reaches the designated number data.

In the circuit of FIG. 10, the random number generator 36
Generates a random number belonging to a certain numerical range, and the sampling circuit 37 samples one random number at an appropriate timing after the start lever 6 is operated. Based on the random numbers sampled in this way and the probability lottery table stored in the ROM 32, a plurality of internal winning combinations are determined.

After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. Reel 3
Reset pulses are obtained from L, 3C, and 3R for each rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. With the reset pulse thus obtained, the count value of the drive pulse counted in the RAM 33 is cleared to "0". This allows RAM3
The count value corresponding to the rotation position within the range of one rotation is stored in each of the reels 3L, 3C, 3R.

A symbol table is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, 3R as described above with the symbols drawn on the outer peripheral surface of the reel. In this symbol table, the reels 3L, 3C, and
The code numbers sequentially given for each fixed rotation pitch of 3R, and the symbol code indicating the symbol provided corresponding to each code number are associated with each other.

Further, a winning symbol combination table is stored in the ROM 32. In the winning symbol combination table, a combination of winning symbols, the number of medal payouts for winning, and a winning determination code indicating the winning are associated with each other. The above winning symbol combination table is referred to when the left reel 3L, the center reel 3C, and the right reel 3R are stopped, and when winning confirmation is performed after all reels are stopped.

When the internal winning is performed by the lottery process (probability lottery process) based on the random number sampling, the CPU
The numeral 31 stops the reels 3L, 3C, 3R based on the operation signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop buttons 7L, 7C, 7R and the selected "stop control table". A control signal is sent to the motor drive circuit 39.

In the case of the stop mode indicating that the winning of the internally won combination is achieved, the CPU 31 supplies a payout command signal to the hopper drive circuit 41 to pay out a predetermined number of medals from the hopper 40. At this time, the medal detection unit 40S counts the number of medals paid out from the hopper 40, and when the counted value reaches the designated number, a medal payout completion signal is input to the CPU 31. As a result, the CPU 31
Stops the driving of the hopper 40 via the hopper drive circuit 41, and ends the "medal payout process".

The block diagram of FIG. 11 shows the configuration of the sub control circuit 72. The sub control circuit 72 performs display control of the liquid crystal display device 5 and output control of sounds from the speakers 21L and 21R based on a control command (command) from the main control circuit 71. The sub-control circuit 72 is formed on a circuit board different from the circuit board that constitutes the main control circuit 71, has a microcomputer (hereinafter referred to as “sub-microcomputer”) 73 as a main component, and uses the liquid crystal display device 5 as a main component.

The image control CPU 82 determines the display content on the liquid crystal display device 5 according to the image control program stored in the image control program ROM 84 based on the parameters set by the sub-microcomputer 73. The image control program ROM 84 stores an image control program relating to display on the liquid crystal display device 5 and various selection tables. The image control work RAM 83 is configured as a temporary storage unit when the image control CPU 82 executes the image control program. Image control IC8

Next, the control operation of the CPU 31 of the main control circuit 71 will be described with reference to the main flow charts shown in FIGS.

First, the CPU 31 performs initialization at the start of the game (step [hereinafter referred to as ST] 1). Specifically, the storage contents of the RAM 33 are initialized, communication data is initialized, and the like. Then, the contents stored in the RAM 33 at the end of the game are erased (ST2). Specifically, the data in the writable area of the RAM 33 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program of the next game is designated, etc. I do. next,
After the last game, that is, all reels 3L, 3C, 3
It is determined whether or not “30 seconds” has elapsed after R stop (S
T3). If this determination is “YES”, the sub control circuit 7
A "demo display command" for requesting the display of the "demo image" is transmitted to 2 (ST4).

Next, the CPU 31 determines whether or not there is a request for automatic insertion of medals, that is, whether or not the replay prize has been established in the previous game (ST5). This judgment is "Y
In case of "ES", medals for the insertion request are automatically inserted (S
The process moves to T6) and ST8. The determination in ST5 is “NO”
In the case of, it is determined whether or not there is an input from the inserted medal sensor 22S or the BET switches 11, 12 and 13 (ST7). If this determination is “YES”, the process proceeds to ST8, and if “NO”, the process proceeds to ST3.

Next, the CPU 31 determines whether or not there is an input from the start switch 6S based on the operation of the start lever 6 (ST8). If this determination is "YES", it is determined whether or not "4.1 seconds" have elapsed since the previous game started (ST9). If this determination is "YES", the process proceeds to ST11, If "NO", ST1
Move to 0 processing. In the processing of ST10, "game start waiting time digestion processing" is performed. Specifically, the process of invalidating the input based on the player's operation for starting the game is performed until “4.1 seconds” has elapsed since the previous game started.

Next, the CPU 31 performs reel rotation processing (ST11), and at the same time extracts random numbers for lottery (ST).
12) Set 1 game monitoring timer (ST1
3). The random number extracted in the process of ST12 is used in the probability lottery process described later. ST13 processing 1
The game monitoring timer includes an automatic stop timer for automatically stopping the reels regardless of the stop operation of the stop button by the player.

In the process of ST14 in FIG. 13, a game state monitoring process for determining the current game state is performed. Subsequently, as will be described later with reference to FIG. 15, a probability lottery process is performed based on the random number value extracted in the process of ST12 (ST15). In this probability lottery process, the probability lottery table is used according to the gaming state, it is determined which random number value range the random number belongs to, and the internal winning combination (establishment flag)
Is to determine. Subsequently, a bonus stock process (FIG. 16 described later) for updating the stored contents of the bonus stock counter is performed (ST16), and the process proceeds to ST17. In the process of ST17, the hit display lamp lighting process is performed, and then the process proceeds to ST18. In the hit display lamp lighting process, the process of lighting the hit display lamp 17 is performed during the “normal period” when there is stock. In the process of ST18, a stop control table selection process described later (FIG. 18 described later)
Then, the process proceeds to ST19. In the processing of ST19,
Performs transmission processing at the start of the game. Specifically, a process of transmitting a command including the information of the internal winning combination, the determination result of the stop control table selection process, and the like to the sub control circuit 72 is performed.

Next, the CPU 31 determines whether or not the stop button is "ON" (ST20). Specifically, it is determined whether any of the stop buttons has been operated.
If this determination is "YES", the process proceeds to ST22, and if "NO", the process proceeds to ST21. ST2
In the process of 1, it is determined whether or not the value of the automatic stop timer is "0". If the determination is "YES", ST22
If NO, the process proceeds to ST20.

In the process of ST22, the CPU 31 performs a sliding frame number determination process. In this sliding frame number determination process,
A process of determining the number of sliding symbols is performed based on the stop control table selected in the stop control table selection process and the stop operation position of the player. Then, the reel corresponding to the stop button that has been stopped is rotated by the number of slide frames and then stopped (ST23). Here, the “number of sliding symbols” indicates the number of symbols that have moved between the time the stop button was operated and the time the reel stopped. Also, the "number of sliding pieces" is the code number of the symbol that was located on the predetermined pay line when the stop button was operated, and the code of the symbol that was stopped on the prize line when the reel actually stopped. It is represented by the absolute value of the difference from the number. This "number of sliding pieces" may be referred to as the "number of pull-in."

In the process of ST24, the CPU 31 determines whether or not all reels have stopped, and this determination is "Y".
If "ES", the process proceeds to ST25, and if "NO", the process proceeds to ST20. In the process of ST25, an "all reel stop command" indicating that all reels have stopped is transmitted, Then, the process proceeds to ST26 of 14.

In the processing of ST26 of FIG. 14, the CPU 31
Performs a prize search. Winning search means display windows 4L, 4C,
It is to set a winning flag for identifying a winning combination (a winning combination is achieved) based on the stop mode of the 4R symbol. Specifically, the winning combination is identified based on the code numbers of the symbols arranged along the center line 8c and the winning determination table. Then, it is determined whether or not the winning flag is normal (ST27). If this determination is "NO", an illegal error is displayed (ST28). In this case, the game is canceled. If the determination in ST27 is "YES", the bonus stock counter subtraction process described later with reference to FIG. 19 is performed, and the process proceeds to ST30. S
In the process of T30, medals are credited or paid out according to the gaming state.

Next, it is determined whether the current game state is the BB general game state or the RB game state (ST3).
1). If this determination is "YES", a bonus "game number check process" is performed (ST32). In this "game number check process", the number of times the RB game state has occurred, B
The number of games in the B general game state, the number of winnings in the RB gaming state, and the number of games in the RB gaming state are checked.

Next, it is determined whether or not the bonus is over (ST33). Specifically, after the winning of the BB is established, the number of winnings is 8 in the third RB game state.
It is determined whether the number of times or the number of games is 12 or whether the number of games is 30 in the BB general game state. Further, after the RB winning is established in the general game state, it is determined whether or not the number of winnings is 8 or the number of games is 12 in the RB playing state. If the determination in ST33 is "YES", the process returns to the normal gaming state, which is a normal gaming state, by the processing in ST36, which will be described later.
The information stored in the predetermined area in the AM 33 is cleared (ST34). Subsequently, a high-probability replay period selection process which will be described later with reference to FIG. 17 is performed (ST35).

Next, a game state change process is performed (ST3
6). Specifically, when the winning of BB is established, the gaming state is set to the BB general gaming state. When the winning of the RB is established, the gaming state is set to the RB gaming state. When the determination in ST33 is "YES", the gaming state is set to the general gaming state. Then, a "game state command" including information on the current game state is transmitted to the sub control circuit 72 (ST37). Then, the process proceeds to ST2.

Next, the probability lottery process will be described with reference to FIG.

First, the CPU 31 determines whether or not the current game state is the general game state (ST41). If this determination is “YES”, the process proceeds to ST42,
If "NO", the process proceeds to ST45. In the process of ST42, it is determined whether or not it is currently in the "high probability replay period", that is, whether or not the high probability replay flag is set. If this determination is “YES”, the process proceeds to ST46, and if “NO”, the process proceeds to ST43. In the process of ST43, the internal winning combination is determined (selected) based on the probability lottery table for the normal period (FIG. 4 (1)) and the random number value extracted in the process of ST12 of FIG.
Subsequently, the information of the selected internal winning combination is stored in the RAM 33 (ST44), and the process proceeds to ST16 of FIG. When the current gaming state is not the general gaming state (when the determination in ST41 is "NO"), the internal winning combination is determined based on the probability lottery table (not shown) corresponding to the gaming state (S
The process moves to T45) and ST44.

When the determination in ST42 is "YES",
That is, when the current “high-probability replay period” is set, the internal winning combination is made based on the probability lottery table for the high-probability replay period (FIG. 4 (2)) and the random number value extracted in the process of ST12 of FIG. It is determined (selected) (ST46). Next, "1" is subtracted from the number of continuous games during the high-probability replay period (ST
47). Subsequently, it is determined whether or not the number of continuous games during the high-probability replay period is "0" (ST48). If this determination is “YES”, the process proceeds to ST49, where “N
When "O", the process proceeds to ST44. In the process of ST49, by clearing the high-probability replay flag,
Shift from "high probability replay period" to "normal period"
The process moves to T44. Here, when the "high-probability replay period" occurs, any number shown in FIG. 8 is set as the number of continuous games (the processing of ST63 in FIG. 17, which will be described later, is performed), and each time the game is played, that number of times is set. The value is subtracted.

Next, the bonus stock process will be described with reference to FIG.

First, the CPU 31 determines whether or not a bonus is internally won in the current game (ST61).
If this determination is “YES”, the process proceeds to ST52, and if “NO”, the process proceeds to ST17 in FIG. In the process of ST52, the bonus stock counter is prioritized and the information of the internally won bonus is stored. The content stored in the bonus stock counter is ST52.
By the process of, the process shifts from, for example, FIG. 9A to that shown in FIG. 9B. Next, it is determined whether or not it is currently the "high probability replay period" (ST53). This judgment is "YE
If "S", the process proceeds to ST17 of FIG.
When it is "O", that is, when the bonus is internally won in the "normal period", a high-probability re-game period selection process described later with reference to FIG. 17 is performed, and the process proceeds to ST17 of FIG.

Next, with reference to FIG. 17, a high probability replay period selection process will be described. Here, the high-probability replay period selection process is performed after the process of ST34 of FIG. 14 or FIG.
It is performed after the processing of ST53.

First, the CPU 31 determines whether or not bonuses are stocked (ST61). If this determination is “YES”, the process proceeds to ST62 and “N
When it is "O", ST36 in FIG. 14 or ST17 in FIG.
Move to processing. Here, as described above, the probability of winning the bonus is lower than the probability of internally winning the bonus, and therefore the determination in ST61 is rarely "NO".

Next, in the bonus stock counter, a random number lottery for determining the number of continuous games is performed based on the type of the bonus having the "first place" priority (ST6).
2). For example, when the random number value extracted from the range of “0” to “255” is “200”, the number of continuous games is determined (selected) as “600”. Next, the CPU 31 sets the number of continuous games in the selected high-probability replay period to "600" (ST63), and proceeds to the process of ST64. In the process of ST64, the high-probability replay flag is set (ST6
4). That is, the “normal period” is shifted to the “high-probability replay period”. Then, ST36 of FIG. 14 or FIG.
The process moves to ST17 of 3.

Next, the stop control table selection process will be described with reference to FIG.

First, the CPU 31 extracts a random number for selecting the stop control table (ST71). Subsequently, it is determined whether or not it is currently in the "high probability replay period" (ST7).
2). If this determination is “YES”, the process proceeds to ST73, and if “NO”, the process proceeds to ST78. Here, when the bonus is internally won in the game in the "normal period", the high-probability re-play flag is set before the process of ST72 is performed (ST of FIG. 16).
The processing of ST64 of FIG. 17 is performed via 54).
That is, even when the bonus is internally won in the “normal period”, the stop control is the same as that in the “high probability replay period”. In the process of ST73, it is determined whether or not the small winning combination is internally won. This judgment is "YES"
In case of, it moves to the processing of ST74, in case of "NO",
The process moves to ST75. In the processing of ST74, the stop control table is selected from the stop control table group in which the winning of the internally won small winning combination is possible. Here, the stop control table group refers to a set of a plurality of stop control tables. Then, it transfers to the process of ST19 of FIG.

When the determination in ST73 is "NO", it is determined whether or not the internal game is won in the replay (ST75). If this determination is “YES”, the process proceeds to ST76,
When the result is “NO” (when the internal winning combination is “bonus” or “none (missing)”), the process proceeds to ST77. S
In the process of T76, based on the random number value extracted from the range of “0” to “65535” and the re-play selection table (FIG. 7), whether the winning is established (FIG. 5) or the winning is not established (FIG. 6). Select one of the stop control tables and select ST19 in FIG.
Move to processing. In the process of ST77, the stop control table is selected from the stop control table group in which the winning of the bonus cannot be established, and the process proceeds to the process of ST19 of FIG.

When the determination in ST72 is "NO", that is, when it is the "normal period" at present, it is determined whether or not the bonus is stocked (ST78). If this determination is “YES”, that is, if the condition for excluding the bonus prize is satisfied (excluding the condition of the stop operation timing), the process proceeds to ST79, and if “NO”, the process proceeds to ST80. Move on to processing. In the process of ST79, in the bonus stock counter, the stop control table is selected from the stop control table group in which the winning of the bonus with the priority of "1st place" can be established, and the process proceeds to the process of ST19 of FIG. In the processing of ST80, based on the internal winning combination,
The stop control table is selected from the stop control table group in which the winning of the internal winning combination is possible, and ST19 of FIG.
Move to processing.

Next, the bonus stock counter subtraction process will be described with reference to FIG.

First, the CPU 31 determines whether or not a bonus prize has been established (ST91). If this determination is “YES”, the process proceeds to ST92, “NO”.
If so, the process proceeds to ST30 of FIG. In the process of ST92, the bonus stock counter erases the information of the bonus having the "first place" priority. Subsequently, it is determined whether or not bonuses are stocked, that is, whether or not there is a bonus having a priority of "2nd" (S).
T93). If this determination is “YES”, the process proceeds to ST94, and if “NO”, the process proceeds to ST30 of FIG. In the process of ST94, the priorities of bonuses whose priority is “2nd place” or lower are advanced one by one. The stored contents of the bonus stock counter are changed to those shown in, for example, FIG. 9 (1) to FIG. 9 (3) by the processing of ST94.

Although the embodiment has been described above, the present invention is not limited to this.

In the embodiment, the "high probability replay period" is adopted as the predetermined situation, but it is not limited to this. For example, "a situation in which there is a high probability of being internally won for a so-called single bonus", "a situation in which there is a high probability of being internally won for a predetermined small combination", and "reel stop control is basically performed only based on the timing of the player. That is, any situation such as a situation in which the stop operation position and the stop control position match (so-called “challenge time (CT)”) can be adopted. Further, as the predetermined combination, an arbitrary combination such as a predetermined small combination, a single bonus, BB, and RB can be adopted.

If the reciprocal of the probability that the increasing winning combination is determined to be the internal winning combination is smaller than the expected value of the number of games for which the predetermined situation continues, the occurrence condition and the ending condition of the predetermined situation are as follows. It can be set arbitrarily. For example, as the generating condition or the ending condition, the determination result of the internal winning combination determining means is a predetermined result (for example, the internal winning combination is “none (out)”, the internal winning combination is a predetermined small winning combination, and the random number). It is also possible to adopt the result of the lottery. It is also possible to employ, as the occurrence condition or the end condition, a condition based on the game results of a plurality of games (internal winning combination, winning combination, etc.).

Further, as the occurrence condition or the ending condition of the predetermined situation, a condition related to the game operation of the player in one or a plurality of games (mode of operation of stop button (operation timing or operation order)) is adopted. You can also do it. In this case, the sub-control circuit 72 may increase the “information relating to the above-described operation mode in which the generation condition or the end condition is satisfied or not satisfied”, “the possibility that the generation condition or the end condition is satisfied or not satisfied, or Information related to the game operation, such as "information related to the mode of operation that will be reduced" can be notified. Even when information is not transmitted from the sub control circuit 72 to the main control circuit 71, the player responds to the above notification by the notification means (the liquid crystal display device 5 or the like) based on the control of the sub control circuit 72. By operating the stop button (stop operation unit) at, for example, a generation condition is satisfied and a predetermined situation occurs. Further, for example, the termination condition is not satisfied and the predetermined situation is not terminated. That is, the determination of the sub control circuit 72 is reflected in the determination of the main control unit through the operation of the stop operation unit by the player, so even if the function of the main control circuit 71 is limited, the game machine is interesting. Will be provided.

In the embodiment, in the "high probability replay period" which is an example of a predetermined situation, whether or not the winning of the replay is achieved by the internal lottery, that is, the "pull-in control" or the "kick-off control" It is not limited to this. For example,
The operation mode of the stop button for performing the "pull-in control" (operation sequence of the stop button, operation timing, or the like) is determined. Then, a value obtained by multiplying the probability that the operation is performed in that manner by the probability of internally winning the “re-play” which is an example of a predetermined hand in the “high-probability re-play period” is the “re-play” in the “normal period”. It can be made equal to the probability of internally winning the game. In this case, the player can increase the number of medals he or she has by notifying the mode of the operation, so that the interest of the game is increased.

Further, a part or all of the information stored in the bonus stock counter can be notified by using a notification means such as the liquid crystal display device 5. Also, regarding the bonuses that have been stocked, "date internally won", "time",
"After the game was powered on, the number of games required to win the internal prize", "After the previous bonus prize was established,
It is also possible to inform the player of information related to the internal winning such as "the number of games required until the internal winning". In addition, the timing of notification can be any time such as when the stocked bonus is won. Further, in a predetermined situation, it is possible to notify that the bonus is internally won by using the notification means such as the liquid crystal display device 5.

Further, in the embodiment, the winning of the bonus with the priority of "1st place" is prioritized, that is, the winning of the increasing combination in the earliest order of the internal winning is realized. It is not limited to this. For example, it is also possible to achieve the winning of the winning combination in the order of the latest internal winning.

Further, the contents of the bonus stock counter may not be erased by changing the "setting" generally provided in "6 stages". In addition, by adjusting the number of continuous games in a predetermined situation, it is possible to equalize the probability of internally winning a bonus in each setting. In the embodiment, both BB and RB are provided as an increasing hand, but only BB or R is provided as an increasing hand.
Only B may be provided. Further, as the increasing combination, it is possible to employ any combination capable of acquiring game media such as medals over a plurality of games. Further, “0” may be set as the number of continuous games. Also, certain situations (for example, high probability replay period)
If the bonus is internally won within the specific period in, the information necessary to realize the winning of the internally-winned winning combination in the BB general game state or the RB gaming state caused by the bonus winning establishment ( For example, the operation order of the stop button, the operation timing, etc.) can be notified. This increases the fun of the game.

Furthermore, the present invention can be applied to other gaming machines such as a pachinko gaming machine in addition to the slot machine as in the present embodiment. Furthermore, the present invention can be applied to execute a game even in a game program in which the above-described operation of the slot machine is simulated for a home-use game machine. In that case, as the recording medium for recording the game program, a CD-ROM, an FD (flexible disk), or any other recording medium can be used.
