Further, in the symbol display means described later, a predetermined winning line is activated (hereinafter, the activated winning line is referred to as an "effective line"). In the present embodiment, the selector 66 that detects the insertion of medals by the player constitutes the insertion operation detecting means. The types of game media that can be detected are not limited to medals, but include coins, tokens, game balls, and electromagnetic game media having an equivalent value.

<Start operation detection means>
The start operation detecting means detects a start operation by the player. When the start operation is detected, the variable display of the symbol by the symbol display means described later is started. Further, a random number value used when the internal winning combination determining means, which will be described later, determines the internal winning combination is extracted from a predetermined numerical range (for example, 0 to 65535). Further, the effect random value used when the effect control means described later determines the effect is extracted from within a predetermined numerical range (for example, 0 to 32767). In the present embodiment, the start switch 79 that detects the operation of the start lever 23 by the player constitutes the start operation detecting means. The type, number, and numerical range of the extracted random number values are not limited to this, and the number of random number values required for the game can be extracted from within a predetermined numerical range. ..

<Means for determining the internal winning combination>
The internal winning combination determining means draws a lot based on the extracted random number value, and determines the internal winning combination from a plurality of predetermined combinations. That is, the combination of symbols that are allowed to be displayed on the valid line is determined by the determination of the internal winning combination. In the present embodiment, the main control circuit 91 that refers to various tables and executes the internal lottery process based on the extracted random number values constitutes an internal winning combination determining means. The types of symbol combinations include those related to "winning" in which benefits such as medal payout, replay operation, bonus operation, etc. are given to the player, and other so-called "losses". Such things are provided.

In addition, the pachislot machine can control the progress of the game to be stopped. Such control is referred to as "locking" (or "freezing"). For convenience, the control that stops the progress of the game executed at the start of the game is called "lock at the start of the game", and the control that stops the progress of the game executed at the end of the game is called "lock at the end of the game". Call. That is, the "lock at the start of the game" is a control in which the progress of the game is stopped in the sense that the operation to the stop button is not effective for a predetermined period after the start lever is operated. "Lock at the end of the game" means that the operation of the bet button or the operation of the start lever is not effective for a predetermined period after the stop button is operated, and the progress of the game is stopped. Control. Of course, the trigger of "locking" is not limited to the above, and for example, after the start lever is operated and one of the stop buttons is operated, the subsequent operation is effective for a predetermined period. It may be possible to perform control that does not become.

Here, the internal winning combination determining means can perform a lottery based on the extracted random number value, and determine whether or not to perform "locking" in place of the internal winning combination or together with the internal winning combination. In this case, a plurality of random numbers are extracted, the internal winning combination is determined based on one of the random values, and whether or not to perform "lock" is determined based on the other random value. May be.
