PROBLEM TO BE SOLVED: To properly perform a read-ahead presentation even if before a start of a variation presentation, a mode for the variation presentation cannot be specified.SOLUTION: When a game ball enters a start port, a random number for performing a lottery for a big win and a variation presentation random number value for determining a mode for a variation presentation are obtained and stored. The variation presentation random number value is classified into: a fixed value in which a same mode for the variation presentation is determined in any table of a plurality of variation presentation determination tables for failures; a first constant value in which a ready-to-win variation pattern can be determined by a selected variation presentation determination table for a failure; and a second constant value that becomes a pattern without a ready-to-win in any of the plurality of variation presentation determination tables for failures. Different determination processing is performed for a performance mode of a read-ahead presentation in a case where reservation information classified as the second constant value is stored and in a case where reservation information classified as the first constant value is stored.SELECTED DRAWING: Figure 12 |
