It should be noted that four or more medals are not inserted. The game starting means 61 is the start lever 3
Based on the start signal from the start switch 35a interlocked with 5, when the number of medals counted by the medal number counting means 60 is 1 to 3, the start of the game control is instructed. The lottery means 62 performs a random number lottery at the time of receiving a game start command from the game start means 61, and 8 shown in FIG.
Any one of eight types of winning combinations (a big winning combination, a small winning combination, a small winning combination 1 to a small winning combination 4, a replay winning combination, and a non-winning combination) corresponding to each of the different winning modes is determined.

The lottery probabilities for randomly selecting these eight types of winning combinations are set values selectively set from the six types of setting values (1 to 6) on the game hall side, and "the number of medals inserted at the start of the game. (Any of 1 to 3 sheets) ”. The flag setting means 63 sets and stores a permission flag (a big bonus flag, a regular bonus flag, a small combination 1 flag to a small combination 4 flag, a replay flag, a removal flag) corresponding to the combination determined by the lottery means 62. . However, the big bonus flag and the regular bonus flag are stored and held until the big hit or the small hit occurs when the big hit or the small hit does not occur in the game in which the permission flag is set.

The reel control means 64 is a game starting means 61.
While starting the rotation of the rotary reels 3 to 5 when a game start command is received from the stop button 36 to 38a interlocked with the stop buttons 36 to 38, the operated stop button 36 to 38a. 38

It is possible to display and stop the rotation of the first to third rotating reels 3 to 5. The stop symbol determination means 65, when the rotation of all the rotating reels 3 to 5 is stopped, types of stop symbol modes that are established side by side on the activated pay lines 44 to 46 (big hit mode, small hit mode, 4 Any one of a small winning combination mode, a replay mode, and a disengagement mode) is determined.

The profit state generating means 66 has a special game generating means 67, a specific bonus game generating means 68, a change setting means 69 and the like. Special game generating means 67
When the jackpot mode is established and the big bonus is generated, the special game is basically generated over 30 times. The specific bonus game generation means 68 basically generates the specific bonus game twice when the JAC IN stop symbol mode (corresponding to the specific mode) such as the replay mode is established, and further each In the specific bonus game, the maximum number of winning games of the bonus game to be the specific winning is generated over 6 times.

However, the specific bonus game generating means 68
Changes the game mode to 2 special bonus games.
It can be generated more than once, and the maximum number of winning games can be generated 6 times or more. The change setting unit 69 has a game mode storage unit 70 shown in FIG. 7, and selects a game mode selection switch 71a by the player from the first to eighth game modes stored in advance in the game mode storage unit 70. By the operation of, one game mode is selectively selected and set. Here, the number of times associated with each of the maximum number of continuations of the special game, the maximum number of operations of the specific bonus game, and the maximum number of winning games in the specific bonus game is preset in each game mode.

In this case, in each of the first game mode to the third game mode, the maximum number of operations of the specific bonus game does not change to "2 times", but the specific prize is awarded in accordance with the decrease of the maximum number of continuation of the special game. The maximum number of winning games is increased. Further, regarding the fourth to fifth game modes, the maximum number of operations of the specific bonus game increases to “3 times” in accordance with the decrease in the maximum number of continuations of the special game, and the maximum winning game that becomes the specific prize. The number of times also increases.

Further, in the fifth game mode, the maximum number of operations of the specific bonus game decreases and the maximum number of winning games as the specific prize also decreases in accordance with the increase of the maximum number of continuations of the special game. Furthermore, the 7th mode-
In each of the eighth modes, the maximum number of operations of the specific bonus game increases as the maximum number of continuations of the special game decreases, while the maximum number of winning games as a specific prize decreases.

However, in the profit state generating means 66,
The probability that a specific mode such as a replay mode will occur and the probability that a specific prize will occur in a specific bonus game will be constant regardless of the increase / decrease in the maximum number of continuations of the special game due to the change of the game mode by the change setting means 69. Is controlled. Therefore, even when the game mode is changed, a certain lottery probability can always be maintained, and each game in the big bonus can be played fairly.

Upon receiving the determination result from the stop symbol determining means 65, the medal awarding means 72, when a winning mode such as a big winning mode, a small winning mode, or a small winning mode is established, the number of coins corresponding to the winning mode is obtained. A medal (see FIG. 4) is given to the player. However, during the big bonus or the regular bonus, a predetermined number of medals are paid out even in the case of a special small prize mode such as a replay mode. At that time, in the storage mode, the number of stored sheets is a predetermined maximum number (5
When the number is less than 0, the medals to be given are accumulated cumulatively. When the stored number exceeds the predetermined maximum number, the medals of the exceeded number are taken out by the medal payout device 5
Issued by 5.

However, when the payout mode is set, all the medals to be given are all paid out by the medal payout device 5.
Issued by 5. The display control means 74 controls the stored number display section 25, the special game display section 26, and the provided number display section 27 to cause the aforementioned display. The sub control board 51
The sub-control unit 51A configured above has a liquid crystal display unit 12
Display control means 75 for controlling the display of the upper lamp 10,
11 and back lamp group 58 (9 back lamps 5
The lamp control means 76 for controlling 6) and the voice control means 77 for driving and controlling the speaker 40 are provided.

Next, the game mode setting control executed by the main control means 50A will be described with reference to the flowchart of FIG. However, the symbols Si (i = 11, 1 in the figure)
2, 13 ...) are each step. When the slot machine 1 is powered on, this control is started, and an initial value "1" is first set as the game mode number GN (S
11) Repeat S12 until a big bonus occurs.

In the middle of the game by the player, red "7,7,7" or white "7,7,7" become a big hit and a big bonus occurs (S12: Yes).
), A list of game modes is displayed on the liquid crystal display unit 12 (S13). For example, as shown in FIG. 3, the liquid crystal display unit 1
2, a list of first to eighth game modes stored in advance in the game mode storage means 70 is displayed, and the first game mode at the head is highlighted (see FIG. 3).

Then, the player selects the game mode selection button 7
When 1 is operated (S14: Yes), the game mode number GN
Is not the maximum "8" (S15: No), the game mode number GN is incremented by 1, and the game content of the game mode number GN is highlighted (S17). However, when the game mode selection button 71 is operated and the game mode number GN is the maximum "8" (S15: Ye
s), the game mode number GN is set to the initial value "1" (S16).

When the start lever 35 is operated while the desired game mode is selected by operating the game mode selection button 71 multiple times (S18: Yes).
), The selected game mode number GN is set, and the list of game modes displayed on the liquid crystal display unit 12 is erased (S19). As a result, the game mode of the big bonus is changed to the game mode of the selected game number. Here, when the player selects the "first game mode", the maximum number of continuations of the special game is "30 times", and the maximum number of operations of the specific bonus game is "2".
The maximum number of times of winning games, which is a specific winning, is “6 times”, which is a standard mode.

However, when the beginner plays a game in which it is easy to JAC IN immediately after the big bonus is started and most of the 30 special games cannot be effectively played,
By selecting the "second game mode" or the "third game mode", the maximum number of continuations of the special game is "20 times" or "1".
0 times "instead, the maximum number of winning games instead of" 7 "
The number can be increased to “8 times” or “8 times”, and the big bonus can be enjoyed under a condition advantageous for a beginner.

Alternatively, as a beginner, by selecting the "second game mode" or the "third game mode", the maximum number of continuations of the special game is reduced to "20 times" or "10 times" and instead the maximum The number of operations can be increased to “3 times” and the maximum number of winning games can be increased to “7 times”.

On the contrary, even if the big bonus is started
When a player who is good at replay removal so as not to JAC IN, plays the game, by selecting "6th game mode", the maximum number of activations of the specific bonus game is set to "1". Even if the maximum number of winning games is reduced to "5", the maximum number of continuous special games can be increased to "40", and a big bonus can be enjoyed by a skilled player under favorable conditions. Therefore,
The contents of the profit state when a big bonus occurs can be changed and set according to the player's taste and mood.
That is, it is possible to provide the game playability that can meet the needs of the player.

Next, a modification of the embodiment will be described. The same elements as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted. 1] In the game mode storage means 70, as shown in FIG. 9, a maximum number of continuations, a maximum number of actuations, and a maximum prize according to a combination of three game symbols as a jackpot mode for generating a big bonus. The number of games may be changed and set.

In this case, during the game, for example,
When a player wins a jackpot with "7 white, 7 white, 7 white", the maximum number of continuations is changed to "10", but the maximum number of winning games is "8". Will increase. In addition, for example, when "Red 7, White 7, White 7" are aligned and it is a big hit, the maximum number of continuations is reduced to "20" and the maximum number of operations is reduced to "1". However, the maximum number of winning games increases to “10”.

2] As shown in FIG. 10, a special state generating means 78 is additionally provided, and after the completion of the big bonus (special bonus), any one of a plurality of types of small wins which are usually highly likely to be missed. A special state may be generated to inform the liquid crystal display unit 12 whether the small winning combination flag is established. In this case, as shown in FIG. 11, the occurrence rate of the special state informing the winning combination and the ending condition for ending the winning combination informing state according to the maximum number of continuations of the special game in the finished big bonus are ended. The number of continuing games (the number of digesting games) for playing may be set differently.

Further, as shown in FIG. 12, the occurrence rate of the special state for notifying the winning combination and the winning combination notifying state are ended according to the maximum number of times the special game is set for the ended big bonus. It is also possible to set different lottery probabilities for each. In addition, as shown in FIG. 13, the occurrence rate of the special state of notifying the winning combination and the small amount for ending the winning combination notifying state according to the maximum number of times the special game is set for the ended big bonus. The number of winning combinations may be set differently.
