Abstract

PROBLEM TO BE SOLVED: To solve a problem of lack of fun in the B.B game of the conventional slot machine due to prediction enabled earlier for the number of medals which can be obtained during the B.B game. SOLUTION: In the initialization processing of a mystery bonus game, firstly, the possible frequency of playing in the R.B mode during the B.B game is determined by lottery (step 131). The lottery is accomplished by extracting counts of a counter within a CPU 26 to determine the possible frequency of playing in the R.B mode to be two or three from the extracted values. Then, a B.B activation flag is set for a specified region of a RAM 25 (step 132) and the possible frequency of playing in the R.B mode during the B.B game is set for the specified region of the RAM 25 (step 133). Then, the possible frequency of ordinary game in the B.B game is set to 30 (step 134) and thereafter, the mystery bonus game basically identical to the B.B game is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gaming machine for executing a special game in which a game advantageous to a player is performed a plurality of times when a special game internal winning mode is determined.

[0002]

2. Description of the Related Art Conventionally, in such a gaming machine, an internal random winning mode is determined by comparing an extracted random number value with data in a predetermined probability lottery table. There are various forms of winnings given to the player according to the probability lottery result.

For example, in the case of a slot machine, when a predetermined winning symbol is arranged on a variable display section during a normal general game in which various winning modes of a payout are generated, a small winning mode in which a predetermined number of medals are paid out. is there. In addition, there is also a winning mode of a winning game called a regular bonus game (hereinafter referred to as an RB game). This RB game occurs when a predetermined symbol different from a small winning prize symbol is completed during a general game. In the RB game, a high payout game in which a high payout is provided can be performed once.

[0004] A big bonus game (hereinafter referred to as B.
There is also a jackpot winning mode called "game B"). This BB game occurs when predetermined winning symbols different from small hits and middle hits are collected during a normal general game. In the BB game, a set of the BB normal game in which various payout winning modes are generated and the high payout game (RB game) can be performed a plurality of times. That is, in the BB game, a special game in which a game advantageous to the player can be performed a plurality of times is executed.

[0005] The general game during the BB game is the R game during the BB game.
-It is performed before shifting to the B game. In this general game during B / B, a small hit prize is generated with a higher probability than during the above-described normal general game, and when the small hit prize symbols are arranged on the variable display portion, the number corresponding to the small hit is obtained. Is paid out to the player. In such a BB game, a player can usually acquire a large amount of medals.

[0006]

However, in the above-mentioned conventional slot machine, the number of RB games that can be performed during the BB game is determined in advance depending on the model. For example, the number of RB games that can be performed during a B / B game is three on a slot machine of a model called an A type, and the number of RB games that can be performed on a slot machine of a model called a B type is a RB game that can be performed during a BB game. 2 times
The times are predetermined.

For this reason, in the conventional slot machine, when the BB game is started, the number of medals that can be obtained during the BB game is predicted to some extent, which makes the BB game interesting. There was a missing side.

The ROM 24 stores, as a sequence program, a procedure of a game process executed by the slot machine 1, a probability lottery table, a winning determination table, and the like. The RAM 25 has a CPU
A storage area is provided for storing various processing data, flag data, and the like when the processing is performed according to the sequence program.

FIG. 6 conceptually shows a probability lottery table stored in the ROM 24 described above. The probability lottery table stores data for dividing a predetermined range of random numbers generated by the random number generator 31 into each winning mode, and this data is determined by the game state and the number of inserted medals. For example, when one medal is inserted at the time of “general game”, a probability table T _S1 is selected from the table and random numbers in a certain range generated by the random number generator 31 are stored in the table T _S1. Is divided by the data. That is,
It is determined to which group of the section in the table the one random number value specified by the sampling circuit 32 belongs, and an internal winning mode is determined. Here, a control unit 23 including a random number generator 31, a sampling circuit 32, a CPU 26, and the like.
Constitutes a winning mode determining means for determining the internal winning mode by comparing the extracted random number value with data in a predetermined probability lottery table.

Each table T _S1 ,
In T _S2 and T _S3 , the random numbers are _BB game, mystery
Bonus game, RB game, small hit prize game,
It is grouped into replay games (replays) and out-of-office sections. By increasing the number of inserted medals to two or three, the probability of each winning is increased.

In the probability lottery, a BB game, a mystery bonus game or an RB game occurs and the
B flag, mystery bonus flag or RB
If the flag is set but the symbol combination of the BB game, the mystery bonus game or the RB game is not aligned when the reel is stopped, the state immediately before the BB game, the mystery bonus game or the RB game enters. "B ・ B or RB inside hitting”. Here, the mystery bonus game is basically the same as the BB game as described above,
The BB inside hit is equivalent to the mystery bonus game inside hit.

In this game state, the probability extraction shown in the table is performed.
Table T as selection table_F1, T _F2, T_F3Is the input meda

Are grouped into Also, if the game state is “B ・ B
When it comes to "general games", a table
T_B1, T_B2, T_B3Is selected according to the number of inserted medals.
In each of these tables, the random numbers are
Jack game (replay) winning and losing each section
Grouped.

The table shown in FIG. 7 shows an example of data stored in each probability lottery table when the number of medals is three as shown in FIG. That is, the probability lottery table T _S3 when the gaming state is the general game includes 52, 40, 50, 100, and 30 for each of the lottery combinations BB, mystery, RB, watermelon, orange, cherry, and replay.
Numerical data of 0, 2000, and 2245 are stored. Note that the numerical data of the lottery combination of the re-game indicates the probability of winning in the RB game (high payout game) in the game state of the general game during BB. These numerical data indicate a random number width for dividing a random number in the range of 0 to 16383 generated by the random number generator 31. For example, when the probability lottery table T _S3 is used, the BB game has 52/52.
It occurs with a probability of 16384.

The probability lottery table T _F3 in which the gaming state is inside and the probability lottery table T _{B3 in} the case of the general game in BB
Similarly, random number width data for classifying the generated random numbers is stored in the same manner. In the table, a portion in which a horizontal bar without numerical data is indicated indicates that the winning combination is not selected.

The symbol table (not shown) stored in the ROM 24 shown in FIG. 5 associates the rotational positions of the reels 4 to 6 with the symbols, and represents each symbol row by a symbol. . The symbol table includes a code number sequentially assigned to each reel at a constant rotation pitch based on a rotation position at which a reset pulse is generated, and a symbol code indicating a symbol provided corresponding to each code number. Are stored.

A winning symbol combination table (not shown) is stored in the ROM 24. In this winning symbol combination table, the symbol code of each winning symbol combination posted on the payout display section 19,
A symbol code of a symbol combination constituting the “reach eye”, a winning determination code representing each winning, a winning medal payout number, and the like are stored. Here, the reach is a BB or RB when the BB or RB game winning flag is set in the above-mentioned BB or RB inside winning game state set by the internal lottery. This is a symbol combination that suggests to the player that the game is about to occur. The winning symbol combination table is referred to at the time of stop control of the first reel 2, the second reel 3, and the third reel 4, and at the time of confirming a winning after stopping all the reels.

Next, the operation of the slot machine 1 controlled by the control unit 23 will be described with reference to the flowchart shown in FIG.

The CPU 26 first determines whether or not a medal BET has been placed (see step 101 in FIG. 8). This determination is made when a medal is inserted into the insertion slot 10 and a detection signal is input from the medal sensor 33 or when an input is received from the bet switch 12.
In this case, the CPU 26 determines whether or not the game start lever 15 has been operated (step 102) .If the determination is "YES", the CPU 26 instructs the motor drive circuit 34 to output all reels. 4, 5, and 6 are driven to rotate (step 103), and then a probability lottery process is performed (step 104).

This probability lottery process is performed using the probability lottery table shown in FIGS. 6 and 7 for the normal game state and the middle game state inside BB or RB. The random number extracted by the sampling circuit 32 is determined based on which section data in the probability lottery table belongs. Then, a winning flag is set in a predetermined area of the RAM 25 according to the internal winning combination of the section data to which the extracted random number belongs.

Next, as a result of the probability lottery, stop control of the reels 4 to 6 is performed according to the type of the winning flag set (step 105). Then, it is determined whether or not the symbol combination when the reels 4 to 6 are stopped corresponds to any of the internal winning combinations (step 106). If “NO”, the process returns to step 101, and if “YES”, Further, it is determined whether or not the symbol combination at the time of reel stop is the above-mentioned "replay" game (step 107). If this determination is "NO", a predetermined number of medals are paid out (step 108), and the routine proceeds to the next step 109, where "YE"
In the case of S ", the operation returns to the above-described operation determination of the start lever 15 (step 102) without paying out medals.

Next, it is determined whether or not the "BB game" has occurred in the winning determination in step 106 (step 109). If the "BB game" has occurred, BB
After performing the initial setting process (step 110), BB
The game is executed (Step 111). Step 110
The BB initial setting process is shown in the flowchart shown in FIG. In the BB initial setting process, first,
The number of possible games of the RB game, which is the high payout game in the BB game, is set to 2 (FIG. 9A, step 12).
1) Then, the number of times that the general game can be played during the BB game is 30.
(Step 202).

In step 109, the "BB game"
If no "mystery bonus game" has occurred, it is determined whether or not a "mystery bonus game" has occurred (step 11).
2) When the "mystery bonus game" occurs, the mystery bonus game is initialized (step 113), and then the mystery bonus game is executed (step 114). The initialization process of the mystery / bonus game in step 113 is the same as that in FIG.
This is shown in the flowchart shown in FIG.

In this initial setting process, first, the number of possible games of the RB game in the BB game is determined by lottery (FIG. 9B, step 131). This lottery is performed, for example, by counting from 0 to 12 counted by a counter in the CPU 26.
7 is extracted at an arbitrary timing, and if the extracted value is in the range of 0 to 63, R
・ The number of times that the game B can be played is twice, and the extracted value is 64 to
If it is within the range of 127, the number of possible games of the RB game is determined to be three. Here, the control unit 2 including the CPU 26
3 constitutes a continuous number lottery means for selecting the number of times the RB game can be performed.

Next, the mystery bonus game is basically the same as the BB game as described above.
The PU 26 sets the BB operation flag in a predetermined area of the RAM 25 (step 132). Next, step 13
The number of possible games of the RB game during the BB game selected in step 1 is set in a predetermined area of the RAM 25 (step 13).
3) Next, the number of times that the general game can be played during the BB game is 30.
(Step 134).

If the "mystery bonus game" has not occurred in step 112, then "RB
It is determined whether a "game" has occurred (step 11).
5) When the "RB game" occurs, the RB game is executed (step 116).

FIG. 10 and FIG.
1 shows a game process of a BB game performed in 1.

When entering the BB game, first, the CPU
26 determines whether or not a medal BET has been placed (step 201 in FIG. 10). This determination is “YES” when a medal is inserted into the insertion slot 10 and an input is made from the medal sensor 33 or an input is made from the bet switch 12, similarly to step 101 in FIG. 8. In that case, it is next determined whether or not the game start lever 15 has been operated (step 202).

If this determination is "YES", then B.
Using the probability lottery table of the general game during the B game, a probability lottery is performed by the prize mode determining means, and the winning combination of the general game during the BB is determined (step 203). Then the CPU
26 sends a drive signal to the motor drive circuit 34 to rotationally drive all the reels 4, 5, and 6 (step 204). Next, it is determined whether or not a reel stop signal has been input from the reel stop signal circuit 36 by operating the stop buttons 16 to 18 (step 205). The reels 4 to 6 corresponding to the stop buttons 16 to 18 are controlled to stop according to the winning combination (step 206). Then, it is determined whether or not the reel stop control has been performed for all three reels 4 to 6 (step 207). If not all the reels have been stopped, the processing of steps 205 to 207 is repeated.

When the reel stop control for all the reels 4 to 6 is completed in step 207, next, a winning determination as to whether or not there is a hit is performed in the same manner as in step 106 of FIG. 8 (step 208). That is, it is determined whether or not the symbol combination corresponding to the internal winning combination determined by the winning mode determination means in step 203 is stopped and displayed on the reels 4 to 6. If there is no hit, the process proceeds to step 211 described later. If there is a hit, medals are paid out (step 209), and medals are paid out until the number of payouts according to the winning combination is reached (step 210). ).

Next, the general game during BB is set to 1 as described above.
Has been performed 30 times at step 122 in FIG.
Is subtracted from the number of general games that can be performed during the BB game set in the step S1 to update the value stored in the RAM 25 (step 21).
1). Next, it is determined whether or not the winning in step 208 is an RB game (step 212).
If it is the B game, the game processing of the RB game shown in the flowchart of FIG. 11 is performed.

The result of the determination in step 212 is RB
If it is not a game hit, and one of the RB games
When the number of game processes has been completed, it is next determined whether or not the number of RB game playable times in the BB game, which was initially set to 2 in the process of step 121 in FIG. (Step 213). When the number of times reaches 0, the BB game is terminated. When the number of times is not yet 0, next, the general game in the BB game obtained by subtracting 1 in the processing of step 211. It is determined whether the possible number of times has become 0 (step 214). When the number of times becomes 0, the BB game is ended, and when the number of times is not yet 0, the process returns to step 201 to repeat the BB normal game.

Next, the game processing of the RB game which is performed when it is determined in step 212 that the RB game has been won will be described with reference to the flowchart of FIG.

First, the number of possible games of the RB game is set to 12
(Step 231 in FIG. 11), and the number of possible jackpot games in the RB game is set to 8 (step 232). Next, it is determined whether or not a medal BET has been placed (step 233). This determination is made in the same manner as in step 201 of FIG. 10 when a medal is inserted into the insertion slot 10 and there is an input from the medal sensor 33 or when an input is made from the bet switch 12.
S ". In this case, it is next determined whether or not the game start lever 15 has been operated (step 234).

If this determination is "YES", then R.
Using the probability lottery table prepared in advance as the probability lottery table during the B game, the probability lottery is performed by the winning mode determination means, and the winning / non-winning of the jack game is determined (step 235). Thereafter, the CPU 26 sends a drive signal to the motor drive circuit 34 to send all the reels 4, 5, 6
Is driven to rotate (step 236). Next, it is determined whether or not a reel stop signal has been input from the reel stop signal circuit 36 by operating the stop buttons 16 to 18 (step 2).
37) When the reel stop signal is input, the reel 4 corresponding to one of the operated stop buttons 16 to 18
6 to stop control in accordance with the winning / non-winning of the jack game (step 238). Then, it is determined whether or not the reel stop control has been performed for all three reels 4 to 6 (step 239). If not all the reels have been stopped, the processing of steps 237 to 239 is repeated.

When the reel stop control for all the reels 4 to 6 is completed in step 239, it is next determined whether or not there is a jackpot game (step 24).
0). That is, it is determined whether or not the symbol combination corresponding to the jackpot winning is stopped and displayed on the reels 4 to 6. If there is no hit, the process proceeds to step 244 described below.
In step 232, 1 is subtracted from the number of jackpots that can be won in the RB game initially set to 8, and
Is updated (step 241). Thereafter, medals are paid out (step 242), and medals are paid out until the number of payouts according to the jackpot game prize is reached (step 243).

Next, since the RB game is played once as described above, the RB game initially set to 12 in step 231 is executed.
The value stored in the RAM 25 is updated by subtracting 1 from the number of possible games (step 244). Next, step 2
It is determined whether or not the number of jackpot wins in the RB game obtained by subtracting 1 in the process of 41 has become 0 (step 245). If this number is not yet 0, it is next determined whether or not the possible number of jack game play in the RB game, which is obtained by subtracting 1 in the process of step 244, has become 0 (step 246). If this number is not yet 0, the process returns to step 233 to repeat the RB game. In addition, when the number of times that the jack game can be won becomes 0 in step 245, and when the number of times that the jack game can be played becomes 0 in step 246, the B that is initially set to 2 in the processing of step 121,・ B
1 is subtracted from the number of possible R / B games during the game (step 247), and the value stored in the RAM 25 is updated to
・ End the B game processing.

The R performed in step 116 of FIG.
The game processing of the B game is the same as that of the flowchart of FIG.
This is the same as the B game game process.

FIG. 12 is a flowchart showing the game processing of the mystery bonus game performed in step 114 of FIG. In this figure, the same steps as those in the flowchart shown in FIG.

The game processing of the mystery bonus game is the same as the game processing of the BB game shown in FIG. 10 from step 201 to step 212, and the steps after the end of the RB game are different as follows. .

That is, in the mystery bonus game, after the end of the RB game, the continuation determination effect of the RB game is started using the liquid crystal display unit 11 (FIG. 12, step 2).
21). This continuation determination effect is to display to the player whether the RB game is to be continued or to be ended every time the RB game is ended. The signal output from the CPU 26 to the display drive circuit 39 causes the liquid crystal display unit 11 to display the effect. This is performed by producing an image to be displayed. Here, the control unit 23 including the CPU 26, the display drive circuit 39, and the liquid crystal display unit 1
1 constitutes an effect means for effecting and displaying to the player whether the RB game is to be continued or terminated every time the RB game is ended.

Next, it is determined whether or not the number of RB game playable times during the BB game, which was initially set to 2 in the process of step 121 in FIG. 9A, has become 0 (step 2).
22). If this number is not yet 0, it is next determined whether or not the number of ordinary games that can be performed in the BB game, which is obtained by subtracting 1 in the processing of step 211, becomes 0 (step 223). If the number of times is not yet 0, the RB game is continued, so that the continuation determination effect of the liquid crystal display unit 11 is an effect in which the lottery of the continuation determination is a win (Step 2)
24). Thereafter, the game processing returns to step 201, and B
During B, the general game is continued.

On the other hand, as a result of the determination in step 222, R · B
When the possible number of game play becomes 0, and when the result of determination in step 223 indicates that the number of available general play in the BB game has become 0, the continuation determination effect of the liquid crystal display unit 11 is:
The lottery of the continuation determination becomes a stuttering effect (Step 22)
5). Thereafter, the game process of the BB game ends. Although the lottery of the continuation determination is not actually performed inside the machine, the continuation determination effect of the liquid crystal display unit 11 is performed in this manner, so that the player can set the R inside the machine every time the RB game ends.
It feels like the lottery for the B game continuation determination is being performed.

FIG. 13 shows an example of the continuation determination effect described above. When the continuation determination effect is started in step 221, the screen of the liquid crystal display section 11 displays, for example, as shown in the center of FIG. An image is displayed that the clown is wondering which treasure chest to choose. The liquid crystal display of either one of the treasure boxes is displayed in reverse video, and the player can specify the treasure box selected by the clown by operating the key 22 beside the liquid crystal display unit 11.

The effect per lottery performed in step 224 is displayed on the screen of the liquid crystal display unit 11 from the treasure box as shown in the lower left of the figure, irrespective of the type of the treasure box designated by the player by the key operation. 7 "comes out and an image is displayed in which the clown is delighted. In addition, regardless of the type of the treasure box designated by the player by the key operation, the effect of the lottery performed in step 225 is displayed on the screen of the liquid crystal display unit 11 as shown in the lower right of FIG. Appears and an image is displayed in which the clown is disappointed.

According to such a slot machine 1 of the present embodiment, the control unit 23 sets the number of times of the BB regular game and the RB game determined by the lottery using the counter in the CPU 26 during the BB game. Therefore, even if the prize mode determination means determines the BB game internal prize mode, the player cannot know in advance how many RB games will be performed by the internal win.

Therefore, according to the slot machine 1 of the present embodiment, the player does not know how many times the RB game is continuously performed when the mystery bonus game is started. Therefore, when the mystery bonus game starts, the player expects that many RB games will be continuously performed. Also, RB
If it is determined that the game is to be played continuously, the player will feel superior to other players. As a result, a sense of expectation or superiority is newly created in the BB game, and the fun of the BB game is improved.

The slot machine 1 according to the present embodiment
In, the continuation determination of whether the RB game is to be continued or to be ended is effected and displayed on the liquid crystal display unit 11 every time the RB game in the mystery bonus game is ended. Therefore, the player feels the expectation and the superiority every time the RB game ends, because the player looks at the continuation determination effect of the liquid crystal display unit 11 while being excited and excited every time the RB game ends. For this reason, a sense of expectation and a sense of superiority newly born in the BB game are more strongly given to the player, and the fun of the BB game is further improved.

The slot machine 1 according to the present embodiment
In the continuation determination effect display, when the treasure box selected by the clown is designated by key operation of the player as illustrated in FIG. 13, the player feels unity in the effect display of the gaming machine. Become. Therefore, the sense of expectation and superiority felt by the player are amplified by the continuation determination effect display using the liquid crystal display unit 11.

In the present embodiment, the number of RB games is determined in advance for the big bonus game (FIG. 8, step 1).
11) and the slot machine 1 in which both the mystery bonus game (step 114) in which the number of RB games is determined by lottery is performed as a bonus game, a slot machine in which only the mystery bonus game is performed as a bonus game is described. May be.

RB during the mystery bonus game
In the present embodiment, the lottery timing for determining the number of games is performed at the initial setting process timing before the mystery bonus game is executed. However, the timing is not limited to this, and may be performed at any timing. That is, in the present embodiment, the number of executions of the RB game is determined to be two or three in step 131 of the mystery initialization process shown in FIG. 9B, but the second RB game is completed. At the timing, whether or not to execute the third RB game may be determined by lottery.

In each of these configurations, the same operation and effect as those of the above-described embodiment can be obtained.
