(Electronic control device)
At appropriate locations inside the slot machine 10, there is provided an electronic control device 100 that is connected to the reel unit 50, the start switch 25, the stop switch 26, and the like and controls the game.

The electronic control device 100 is composed of, for example, a microcomputer in which a CPU, a ROM, a RAM, an I / F, etc. are connected to each other via a bus, and based on a program stored in the ROM or the like, a reel unit 50, a start switch 25 and stop switch 26 are controlled.
Specifically, the electronic control device 100 includes probability setting means 101, lottery means 110, and game control means 130, as shown in FIG.

Further, as shown in FIG. 1, the lottery means 110 includes a random number generator 111, a random number extractor 112, a first lottery table group 113, a second lottery table group 114, a third lottery table group 115, and a fourth lottery table group. 116, a fifth lottery table group 117, a sixth lottery table group 118, a lottery table selection means 119, and a determination means 120.
As shown in FIG. 1, the game control means 130 includes drive control means 131, winning determination means 132, and hopper control means 133.
(Input stage)
As shown in FIG. 1, an input stage of the electronic control device 100 includes a start switch 25, a stop switch 26, a setting change switch 40 for changing settings, a medal sensor 41, a settlement switch 29, and a medal insertion switch 28. (One or two sheet insertion switches, three sheet insertion switches) are electrically connected.
(Output stage)
A reel unit 50 and a hopper device 51 are electrically connected to the output stage of the electronic control device 100, respectively.
(Probability setting means 101)
The probability setting means 101 is a setting value that can set the winning probabilities for each of the plurality of types of roles in a plurality of stages, in this embodiment, one setting among six setting values from a setting value 1 to a setting value 6 Set the value based on external operations.
(Random number generator 111)
The random number generation means 111 uses a random number used in a lottery to determine a combination of stop symbols on the effective lines 24 of the display windows 21, 22, and 23 in a slot machine game (for example, 0 to 65535 in binary number). It is randomly generated at a predetermined timing. For the generation of random numbers by the random number generating means 111, for example, a so-called hard random number generator or an average sampling method or addition of prime numbers by means of a device such as an oscillation device that outputs a pulse signal or a counter that counts this, for example, CPU And so on, which generate a so-called soft random number by executing a predetermined program.
(Random number extraction means 112)
The random number extraction means 112 is for extracting random numbers from the random number generation means 111. The random number extraction means 112 starts on the condition that a game medal for the game is detected by the medal sensor 41 or that the insertion switch is operated, and that each reel for the game is before the start of rotation. The random number generated from the random number generation means 111 is extracted in response to the operation of the switch 25.

In the case where the random number generating unit 111 generates a so-called hard random number by a device such as an oscillation device that outputs a pulse signal or a counter that counts this, the numerical value generated by the random number generating unit 111 is a continuous value. Strictly speaking, it is not a random number. However, the start switch 25 is always operated by the player, and the operation timing thereof is arbitrary, and it can be said that the start switch 25 is sufficiently random as compared with the count update timing of the counter. Therefore, the extracted numerical value can be handled as a random number substantially.
(Lottery table group)
The lottery table group includes a plurality of “lottery tables” corresponding to the respective setting values, and a plurality of lottery tables at the same setting value all correspond to the respective game states at the same setting value.

  The “lottery table” is a table for determining whether or not a winning combination is determined by the determining means 120, and is a table for determining whether the winning combination corresponds to a winning combination or a deviation other than the winning combination. Specifically, the range that can be taken by the random number generated from the random number generation means 111 is a range that belongs to each role and a range that does not correspond to any role, and the range of values of each range. Are reflected in the winning probabilities of each combination and the probability of losing other than the combination. In the present embodiment, as shown in FIG. 3, the determining role is 1 type BB-A, 1 type BB-B, 1 type BB-C, 1 type BB-D, small role A, small role B, It is a small combination C, replay A, replay B, replay C, special small combination, and the combinations of symbols to be stopped are different.

In addition, as shown in FIG. 3 and FIG. 4, the combinations corresponding to the four types of big bonus games (1 type BB-A, 1 type BB-B, 1 type BB-C, 1 type BB-D) A big bonus profit of the number of games for which the end condition is determined according to the number of games is given.
Also, two types of bonus game roles (1 type BB-A, 1 type BB-B), 1 type of small role (small role C), and 2 types of replay roles (replay B, replay C) include: As shown in FIG. 3, conditions for shifting to five types of replay times are defined.

  Here, the replay time is a gaming state in which the winning probability of the replay role is improved from the general gaming state, and the ending conditions in the five types of replay time are as shown in FIG. ) 1 is 70 games, Replay time 2 (RT2) 2 is 30 games, Replay time 3 (RT3) 3 is 100 games, Replay time 4 (RT4) 4 is 50 games, Replay time 5 (RT5) 5 is 500 games Is set. Therefore, when the gaming state shifts to the replay time, the replay winning probability is improved by a predetermined number of games. The degree of improvement of the winning probability will be described in the lottery table group described later.

As shown in FIGS. 5 to 10, the winning probability includes a first lottery table group 113 to a sixth lottery table group 118 for each set value, and each lottery table group 113 to 118 includes a game. A winning probability is set for each state.
The “set value” is paid to the player according to the result of the game with respect to the number of medals inserted to be used for the slot machine game, which is determined based on the winning probability of the winning combination. For example, six setting values are provided in the present invention, and six settings are provided as shown in FIGS. 5 to 10. One lottery table group is provided for each value.

  The lottery table group will be specifically described.

It is possible to predict whether the current set value is the set value 1 to 3 or the set value 4 to 6.

Next, when the game state becomes the replay time 2 (RT2), if the player knows as a point that the winning probability of the replay B or the replay C changes depending on the setting, the player can play the replay time 1 (RT1). ), It can be predicted whether the current set value is the set value 1, 3, 5 or the set value 2, 4, 6.
In particular, when the replay time 1 (RT1) is predicted to be the set value 1 to 3, if the replay time 2 (RT2) can be predicted to be the set value 2, 4 or 6, the first prediction It can be predicted that the setting value of the slot machine in which the prediction is common and the later prediction is 2.
(Replay time 3)

(Set value 4)
When the set value is 4, the probability of winning big bonus A (type BB-A) is 1/1100, the probability of winning big bonus B (type BB-B) is 1/1250, and big bonus C (type BB-C) has a chance of winning 1/1550, a big bonus D (a kind of BB-D) has a chance of winning 1/1550, a chance of winning a small role A is 1/100, a probability of winning a small role B Is 1/10, the probability of winning the small role C is 1/200, the probability of winning Replay A is 1 / 1.6, the probability of winning Replay B is 1/65536, the probability of winning Replay C is 1 / 65536 is set.
(Set value 5)
When the set value is 5, the probability of winning the big bonus A (type BB-A) is 1/1050, the probability of winning the big bonus B (type BB-B) is 1/1250, the big bonus C (type BB-C) has a chance of winning 1/1550, a big bonus D (a kind of BB-D) has a chance of winning 1/1550, a chance of winning a small role A is 1/100, a probability of winning a small role B Is 1/10, the probability of winning the small role C is 1/200, the probability of winning Replay A is 1 / 1.8, the probability of winning Replay B is 1/65536, the probability of winning Replay C is 1 / 65536 is set.
(Set value 6)
When the set value is 6, the probability of winning big bonus A (type BB-A) is 1/1000, the probability of winning big bonus B (type BB-B) is 1/1200, and big bonus C (type BB-C) has a chance to win 1/1500, a big bonus D (a kind of BB-D) has a chance to win 1/1500, a chance to win small role A is 1/100, and a probability to win small role B Is 1/10, the probability of winning the small role C is 1/200, the probability of winning Replay A is 1/2, the probability of winning Replay B is 1/65536, and the probability of winning Replay C is 1/65536 Is set.

  Thus, for example, in the setting values 1 to 6, the probability of winning the small role A is 1/100, the probability of winning the small role B is 1/10, and the probability of winning the small role C is 1/200. The same winning probability is set for all setting values of the gaming state, and the same winning probability as the small role A, the small role B, and the small role C of the replay time 1 (RT1) having the different gaming state described above. Is set.

Also, for example, the winning probability of Replay A at setting values 1 and 6 is “½”, whereas the winning probability of Replay A at setting values 2 and 5 is “1 / 1.8”, setting value 3, The winning probability of Replay A in 4 is set to “1 / 1.6”.
Therefore, the winning probability of Replay A is set to be lower in the order of set value set values 3 and 4, set values 2 and 5, and set values 1 and 6.

Therefore, by experiencing these two gaming states, the player can predict the current set value to some extent.
First, when the game state is the replay time 1 (RT1), if the player knows as a point that the winning probability of the replay B or the replay C changes depending on the setting, the player can replay time 1 (RT1). It is possible to predict whether the current set value is the set value 1 to 3 or the set value 4 to 6.

  Next, when the game state becomes the replay time 3 (RT3), if the player knows the point where the winning probability of the replay A changes depending on the setting as the information, the player is present at the replay time 1 (RT1). Replay A win probability for setting values 1 and 6 is “1/2”, Replay A winning probability for setting values 2 and 5 is “1 / 1.8”, or Replay for setting values 3 and 4 It can be predicted whether the winning probability of A corresponds to any set value of “1 / 1.6”.

  In particular, at the time of replay time 1 (RT1), after predicting that the set values are 1 to 3, replay A is won with a high probability at replay time 3 (RT3). If the probability is predicted to be “1 / 1.6”, it corresponds to the setting value 3 or 4. Therefore, it is predicted that the setting value of the gaming slot machine in which the first prediction and the subsequent prediction are common is 3. it can.

As described above, the small combination C as the predetermined combination is set to a winning probability having a winning probability equal to 1/10 each when the gaming state is the general gaming state in each of the six stages of setting values 1 to 6. Has been.
The lottery table may have various patterns, but at least the set value needs to have at least three stages with different winning probabilities for any combination.
(Lottery table selection means 119)
The lottery table selecting means 119 first selects a lottery table group corresponding to one set value set by the probability setting means 101 from the plurality of first lottery table groups 113 to sixth lottery table groups 118. To do. Specifically, the lottery table selection means 119 selects the first lottery table group 113 if the set value is set to 1, and selects the second lottery table group 114 if the set value is set to 2. If the setting value is set to 3, the third lottery table group 115 is selected. If the setting value is set to 4, the fourth lottery table group 116 is selected, and the setting value is set to 5. If so, the fifth lottery table group 117 is selected, and if the set value is set to 6, the sixth lottery table group 118 is selected. This selection is made in accordance with the set value set by the probability setting means 101 based on the operation of the setting change switch 40. The lottery table selecting means 119 makes the selection from the first lottery table group to the sixth lottery table group. When any lottery table is selected from the lottery table group 118, the selected lottery table group is not changed unless the setting change switch 40 is operated.

  The lottery table selection means 119 wins a big bonus game, and in the winning game, the combination of stop symbols is a big bonus (1 type BB-A, 1 type BB-B, 1 type) shown in FIG. BB-C. 1 type BB-D) If the winning combination is not a big bonus winning combination, the lottery table group corresponding to the replay time 6 is set to the big bonus game when the big bonus game ends. A lottery table group corresponding to replay time 1, replay time 2 or general game (replay time end) depending on the type of game, replay time 3, replay depending on the combination of stop symbols at replay time 1 or replay time 2 A lottery table group corresponding to time 4 or replay time 5 is selected.

Next, the lottery table selecting means 119 selects a corresponding lottery table from the selected table group according to the gaming state. Specifically, the lottery table selection means 119 selects the general game lottery table in the first lottery table group 113 when the game state is a general game, and the first lottery table group when the game state is a replay time. When the replay time lottery table in 113 is selected and the game state is replay time 2 (RT2), the replay time 2 (RT2) lottery table in the first lottery table group 113 is selected, and the game state is replay time 3 ( In the case of RT3), a lottery table with replay time 3 (RT3) in the first lottery table group 113 is selected. When the gaming state is replay time 4 (RT4), replay time 4 (RT4) in the first lottery table group 113 is selected. The first lottery table is selected when the game state is replay time 5 (RT5). Select lottery table 5 of replay time in Buru group 113, gaming state when replay time 6 (RT6) selects the lottery table 6 replay time in the first lottery table group 113. The lottery table selecting means 119 selects any one of the lottery tables 1 to 6 by the lottery table selecting means 119 except for the first lottery table group 113 (second lottery table group 114 to second lottery table). Similarly, when any lottery table group is selected from the six lottery table groups 118), the lottery table selecting means 119 selects a lottery table corresponding to the gaming state from among the selected lottery table groups.
(Determination means 120)
The determining unit 120 refers to the lottery table selected by the lottery table selecting unit 119, and determines for each role whether the random number value extracted by the random number extracting unit 112 belongs to the lottery table. When the random number value belongs to the area of the role to which the random number belongs, it is determined that the winning role belongs, the winning combination corresponding to the role is set, and it is determined that it does not belong to any of the areas of the role Is determined as a detachment, and the detachment is set.
(Game control means 130)
When a game medal insertion signal is input from the medal sensor 41 or the medal insertion switch 28 provided at the medal insertion slot 27, the game control means 130 activates each line 24 according to the insertion of the game medal. Then, control for advancing the game is started, and the player can play the game.

In addition to the above control, the game control means 130 performs overall control related to the game and includes the following means.
(Drive control means 131)
When the start switch 25 is operated, the drive control unit 131 outputs a drive pulse to start rotation of the stepping motor of each reel of the reel unit 50, and when the stop switch 26 is operated, the determination unit Based on the combination set by the determination at 120, the output of the drive pulse is stopped, and the rotation of the reel stepping motor corresponding to each stop switch 26 is stopped.

  The drive control means 131 detects the origin position of each reel by a sensor provided for each reel, and detects the rotational position of each reel based on the number of drive pulses output to each motor, thereby determining the judgment means 120. When the stop switch 26 is operated when the symbol corresponding to the combination set by the button is within a few frames (for example, 4 frames) from the uppermost stage of the display windows 21, 22, 23, the corresponding to the stop switch 26 The reel stepping motor is controlled to stop on the line 24 on which the symbol is activated. When the symbol corresponding to the combination set by the judging means 120 does not exist within 4 frames from the uppermost stage of the display windows 21, 22, 23, the so-called stop control described above makes the time to stop unnatural. Therefore, the stop control for stopping the reel stepping motor corresponding to the stop switch 26 on the line 24 where the symbol is validated is not performed.

Similarly, when the stop switch 26 is operated when the losing is set by the determination means 120, the drive control means 131 is a line in which the symbol of the role that is not determined to be a winning in the current game is activated. The reel stepping motor corresponding to the stop switch 26 is controlled to stop so as not to stop on 24.
(Winning determination means 132)
The winning determination means 132 has a predetermined combination of symbols arranged on the activated line 24 displayed through the display windows 21, 22, 23 of each reel stopped by the stop control means. When the winning combination corresponds to the winning combination, it is determined that the winning combination is won.

In addition, when it is determined that the winning combination is determined based on the operation of the start switch 25 by the determining means 120 and it is determined that the winning combination is lost (when neither of the winning combinations is won), it is validated. Even if the combination of symbols corresponding to the winning combination is stopped on the line 24, the winning determination means 132 does not determine that the winning is achieved.
(Hopper control means 133)
The hopper control means 133 drives the hopper device 51 with the number of game medals corresponding to a predetermined winning combination on condition that the winning determination means 132 determines that the winning combination has been won. , Pay out from the medal payout exit. When the winning determination means 132 determines replay, the game is played under the same conditions as the immediately preceding game without paying out the game medal and without inserting the game medal.
(Example of game state transition)
An example in which the gaming state changes in the slot machine having the above configuration will be described with reference to FIG.

The lottery table selecting means 119 selects a lottery table group corresponding to one set value from the plurality of lottery table groups shown in FIGS. In the present embodiment, for example, since the setting value is set to 1 by the probability setting means 101, the lottery table selecting means 119 selects a lottery table group corresponding to the setting value 1 shown in FIG.
(start)
In step 100, since the gaming state is a general game, the lottery table selecting means 119 selects a lottery table corresponding to the general game from the lottery table group corresponding to the set value 1.

  Then, with the operation of the start switch 25, the random number extraction unit 112 extracts the random number generated from the random number generation unit 111. The determination unit 120 refers to the lottery table selected by the lottery table selection unit 119 and determines for each combination whether the random number value extracted by the random number extraction unit 112 belongs to the lottery table. . The determination of the combination described here is the same in the following description except that the lottery table selected by the lottery table selecting unit 119 is different. Therefore, unless otherwise specified, in the following embodiments, the lottery unit 110 is simply determined. Explain the role lottery.

  In the next step 101, when the result of determination by the determination means 120 is that the big bonus has been won, the determination means 120 determines that the winning combination corresponding to the big bonus is winning, and in the winning game, the stop symbol Is not a combination of symbols that will win the big bonus (1 type BB-A, 1 type BB-B, 1 type BB-C, 1 type BB-D) shown in FIG. If not, go to the next step 102.

  In step 102, when the big bonus has not been won yet, the gaming state shifts to the replay time 6. Specifically, the lottery table selection means 119 changes the gaming state by selecting a lottery table corresponding to the replay time 6 shown in FIG. 5 from the lottery table group corresponding to the setting value 1. Then, based on the lottery table corresponding to the replay time 6 selected by the lottery table selecting unit 119, the probability setting unit 110 performs the lottery.

  In addition, since the big bonus is won, the drive control means 131 stops the switch 26 when the symbol corresponding to the role of the big bonus exists within 4 frames from the uppermost stage of the display windows 21, 22, 23. Is operated, the reel stepping motor corresponding to the stop switch 26 is controlled to stop on the line 24 in which the symbol of the big bonus is activated.

When the combination of symbols arranged on the activated line 24 matches the symbol corresponding to the big bonus combination, the winning determination means 132 determines that the big bonus combination has been won.
When the winning determination means 132 determines that the big bonus has been won, the process proceeds to step 103 and the big bonus is started.

The content of the big bonus differs depending on the combination of symbols arranged on the activated line 24.
When the type 1 BB-A symbols are ready, the process proceeds to step 103 and the big bonus game (type 1 BB-A) starts.
The big bonus game is a game that can be played in a state where the winning probability of a predetermined combination is higher than that of a general game.

When the number of medals paid out in the big bonus game (type 1 BB-A) reaches 465, the process proceeds to the next step 104, and the big bonus game (type 1 BB-A) is ended.
When the big bonus game (1 type BB-A) is finished, the process proceeds to the next step 105 and shifts to the replay time 1 (RT1).
When shifting to the replay time 1 (RT1), the lottery table selecting means 119 selects a lottery table of the replay time 1 from the selected lottery table group. Then, based on the lottery table corresponding to the replay time 1 selected by the lottery table selecting unit 119, the probability setting unit 110 performs the lottery. In the replay time 1 (RT1) lottery table, as shown in FIG. 12, the winning probability of Replay A is 1 / 7.3, the winning probability of Replay B is 1/150, and the winning probability of Replay C is 1/250. Is set.

Since the winning probability for each set value in each gaming state is displayed on the front panel 11 on the front, the player does not need to know in advance information about the winning probability of the replay role.
When the player continues playing the game and the actual winning number is considered and the winning probability seems high, the winning probability of Replay B is set to a set value 4-6 when the gaming state is Replay Time 1 (RT1). It is possible to estimate that it is 1/150 of the setting values 1 to 3, which is lower than 1/100 of.

  Replay times 1 to 6 are gaming states in which the probability of winning a replay is higher than usual, and 70 games continue in replay time 1. If the number of times that replay is won during the replay time, that is, the number of samples from which the winning probability can be estimated increases, it is easier to determine the winning probability than usual. Replay time 1 will reach the game state of replay time 3 when the combination of stop symbols becomes the combination of symbols of Replay B before reaching 70 games. In the state, the combination of stop symbols is not a combination of symbols of Replay B many times. However, the combination of stop symbols becomes a combination of symbols of Replay B, and after exiting step 105, the game is continued and the process of proceeding to step 105 again is repeated (by continuing a number of games, Depending on how many times the game is spent until the combination of the stopped symbols becomes the combination of the symbols of Replay B in the game state of Replay Time 1, the winning probability of Replay B in the game state of Replay Time 1 can be predicted to some extent. For example, as shown in Fig. 12, when the winning probability of replay B at replay time 1 is 1/150 when the set value is 1 to 3, and when 1/100 when the set value is 4 to 6, In many cases, the game will not win Replay B even after the game ends, or will not win until just before reaching 70 games. If the set value is not 1 to 3, or is often won in a relatively fast game, or if there is almost no win in Replay B before reaching 70 games, the set value is 4 to 6 This means that there is a large number of processes for shifting from step 105 to step 109 even when the combination of stop symbols is a combination of replay C in the gaming state with replay time 1 in step 105 described later. The same is true in the point that it is necessary, and the same applies to the replay time 2 in step 114 described later.

Therefore, the determination of whether the winning probability of Replay B is 1/100 or 1/150 also increases the possibility of grasping the winning probability at the replay time than at times other than the replay time.
When the number of games of replay time 1 reaches 70 games in step 105, as shown in step 106, if the combination of stop symbols is a combination of “Replay B”, the process proceeds to the next step 107 and replay time 3 ( Transition to the gaming state of RT3).

  In step 107, the lottery table selecting means 119 selects a lottery table for the replay time 3 (RT3) from the selected lottery table group. The probability setting means 110 performs a lottery based on the lottery table for the replay time 3 (RT3) selected by the lottery table selection means 119, and determines whether the winning combination is won or not. In the lottery table for replay time 3 (RT3), as shown in FIG. 14, the winning probability of Replay A is set to 1/2, the winning probability of Replay B is set to 1/65536, and the winning probability of Replay C is set to 1/65536. ing.

  Therefore, when the game state is Replay Time 3 (RT3), if Replay A is won about 50 times during 100 games, the winning probability of Replay A is 1/2 (50/100). Since the winning probability of Replay A is ½, setting value 3 is set for replay A approximately 56 times (55.5 / 100), and setting value is approximately 4 or 63 times (62.5 / 100). It is possible to guess whether the set value is 1 or 6 instead of 2 or 5.

On the other hand, in the replay time 1 (RT1) of the previous step 105, if the winning probability of the replay B can be estimated to be 1/150 instead of 1/100, for example, the winning of the replay B of the replay time 1 (RT1) The reason why the probability is 1/150 is that since the set value is 1 to 3, it is estimated that the current set value is 1, 2 or 3.
In this way, the estimated setting at the time of replay time 1 (RT1) is 1 to 3, and the estimated value 1 or 6 at the time of replay time 3 (RT3). The set value is set value 1 which is a set value common to the above two guesses. In this way, the winning probability of a replay role during a replay time with a relatively high probability of winning for a specific role in each gaming state, and at least two different winning probabilities for each gaming state, depending on the set value. By setting, it is possible to guess the current setting value of the slot machine by experiencing the difference in the winning probabilities as the player goes through a plurality of gaming states.

  As shown in step 108, when the number of games at replay time 3 (RT3) is exhausted, that is, when the number of games reaches 100 games, the game returns to the normal game at step 100 again. When the gaming state returns to the general game, the lottery table selection means 119 selects a lottery table for general games from the selected lottery table group. Then, based on the lottery table for general games selected by the lottery table selection means 119, the lottery means 110 performs lottery. In the general game lottery table, as shown in FIG. 11, for example, the winning probability of Replay A is set to 1 / 7.3, the winning probability of Replay B is set to 1/65536, and the winning probability of Replay C is set to 1/65536. ing.

In step 105 described above, until the number of games of replay time 1 (RT1) reaches 70 games, as shown in step 109, if the combination of stop symbols is a combination of “Replay C”, the next step Proceeding to 110, the game state is shifted to the replay time 4 (RT4).
When shifting to the replay time (RT4), the lottery table selecting means 119 selects a lottery table for the replay time 4 (RT4) from the selected lottery table group. The probability setting means 110 performs a lottery based on the lottery table for the replay time 4 (RT4) selected by the lottery table selection means 119, and determines whether the winning combination is won or not. In the replay time 4 (RT4) lottery table, as shown in FIG. 15, the winning probability of Replay A is set to 1/2, the winning probability of Replay B is set to 1/65536, and the winning probability of Replay C is set to 1/65536. ing.

  Then, as shown in step 108, when the number of games at replay time 4 (RT4) is digested, that is, when the number of games at replay time 4 (RT4) reaches 50 games, the game returns to the normal game at step 100 again. When the gaming state returns to the general game, the lottery table selection means 119 selects a lottery table for general games from the selected lottery table group. Then, based on the general game lottery table selected by the lottery table selecting unit 119, the probability setting unit 110 performs the lottery.

In addition, in step 105 described above, as shown in step 111 until the number of games at replay time 1 (RT1) reaches 70G, the combination of stop symbols is a combination of “small role C”. Proceeding to the next step 112, the game state is shifted to the replay time 5 (RT5).
As described above, when the replay symbol B, the replay symbol C, and the small role C symbol are stopped and displayed in the replay time 1 of step 105, the replay time 1 ends and the process proceeds to each step. Although it is difficult to recognize the tendency of winning probability of a set value in the replay time 1 state, by winning a number of games and experiencing the state of the replay time 1 multiple times, Probability trends can be recognized.

When shifting to the replay time 5 (RT5), the lottery table selecting means 119 selects a lottery table of the replay time 5 (RT5) from the selected lottery table group. The probability setting means 110 performs a lottery based on the lottery table of the replay time 5 (RT5) selected by the lottery table selection means 119, and determines whether the winning combination is won or not.
As shown in FIG. 16, the replay time 5 (RT5) lottery table has a winning probability of Replay A of 1 / 7.3, a winning probability of Replay B of 1/65536, and a winning probability of Replay C of 1/65536. Is set.

Then, as shown in step 108, when the number of games at the replay time 5 (RT5) reaches 500 games, the game returns to the normal game at step 100 again. When the gaming state returns to the general game, the lottery table selection means 119 selects a lottery table for general games from the selected lottery table group.
In addition, as shown in 101, when the game state in step 107 described above is the replay time 3 (RT3), the replay time 4 (RT4) in step 110, or the replay time 5 (RT5) in step 112, as shown in 101 In the winning game, the combination of stop symbols is the big bonus (1 type BB-A, 1 type BB-B, 1 type BB-C, 1 type BB-D) shown in FIG. If the combination of symbols is not obtained and the big bonus is not won, the process proceeds to step 102 again, and the gaming state shifts again to the replay time 6 (RT6).

In step 105 described above, when the replay B, replay C, or small role C is not stopped and displayed by the end of the number of games of the replay time 1 (RT1), the process returns to the previously described step 100 to play the game. The state transitions to general gaming.
In step 103 described above,
When the type 1 BB-B symbols are ready, the process proceeds to step 113 and the big bonus game (type 1 BB-B) is started.

When the number of medals paid out in the big bonus game (type 1 BB-B) reaches 465, the big bonus game (type 1 BB-B) shown in step 113 ends.
When the big bonus game (type 1 BB-B) is finished, as shown in step 114, the process shifts to replay time 2 (RT2).
When shifting to the replay time 2 (RT2), the lottery table selecting means 119 selects a lottery table of the replay time 2 (RT2) from the selected lottery table group. Then, based on the lottery table corresponding to the replay time 2 (RT2) selected by the lottery table selecting unit 119, the probability setting unit 110 performs the lottery.

As shown in FIG. 13, the replay time 2 (RT2) lottery table has a winning probability of 1 / 7.3 for Replay A, 1/50 of winning probability of Replay B, and 1/70 of winning probability of Replay C. Is set.
In step 114, when the number of games at replay time 2 (RT2) reaches 30G, as shown in step 106, if the combination of stop symbols is a combination of “Replay B”, the next step 107 proceeds and replay is performed. Transition to the gaming state of time 3 (RT3).

Further, in step 114, if the combination of stop symbols is the combination of “replay C” as shown in step 109 until the number of games at the replay time 2 (RT2) reaches 30G, the next step 110 proceeds. Then, the game state is shifted to the replay time 4 (RT4).
Further, in step 114, when the number of games at replay time 2 (RT2) reaches 30G, as shown in step 111, if the combination of stop symbols is a combination of “small role C”, the next step 112 The game proceeds to the gaming state with replay time 5 (RT5).

  As described above, when the replay symbol B, the replay symbol C, and the small role C symbol are stopped and displayed in the replay time 2 of step 114, the replay time 1 ends and the process proceeds to each step. It is difficult to recognize the tendency of winning probability of a set value in the replay time 2 state, but by winning a lot of games and experiencing the state of the replay time 2 multiple times, Probability trends can be recognized.

Also, in the above-described step 114, when the replay B, the replay C or the small role C is not stopped and displayed by the end of the number of games at the replay time 2 (RT2), the process returns to the previously described step 100 to play the game. The state transitions to general gaming.
In step 105 or step 114 described above, during replay time 1 or replay time 2, as shown at 101, a big bonus is won, and in the winning game, combinations of stop symbols are shown in FIG. If the combination is not a combination of symbols for winning the big bonuses shown (1 type BB-A, 1 type BB-B, 1 type BB-C, 1 type BB-D) and the big bonus is not won, step 102 is performed again. The game state again shifts to replay time 6 (RT6).

Also, in step 103 described above, when the big bonus symbols (1 type BB-C, 1 type BB-D) other than the 1 type BB-A or 1 type BB-B symbols are arranged, the big bonus game is played. Start.
When the number of medals paid out in the big bonus game (1 type BB-C, 1 type BB-D) reaches 356, the process proceeds to step 115 and the big bonus game ends.

When the big bonus game is over, the process returns to the normal game in step 100 again.
Further, in the general game of Step 100 described above, when the combination of stop symbols is a combination of Replay B, Replay C, or Minor C as shown in Step 116, as shown in Step 106, respectively. If it is Replay B, the process proceeds to Step 107. If it is Replay C as shown in Step 109, the process proceeds to Step 110. If it is a combination of the small combination C as shown in Step 111, the process proceeds to Step 112.
