Title: Game machine
Inventor: IMOTO MASAHIKO
IPC: A63F7/02
Filed: 2020-01-15
Abstract: To provide a game machine capable of determining a degree of expectation toward winning in performance units under one variation performance while suppressing loss of interest in a game.SOLUTION: In a plurality of notice performances indicating degrees of expectation toward a jackpot under a variation performance, a rank of a degree of expectation indicated by each of the notice performances is separately determined. In this case, when a degree of expectation toward a jackpot of one rank is indicated in a notice performance under a variation performance, in a next notice performance (a subsequent notice performance), patterns which correspond to ranks having lower degrees of expectation toward a jackpot than that of the one rank are not selected in determination of the rank of the degree of expectation shown in the next notice performance. Thus, a decrease in degree of expectation toward a jackpot after a high degree of expectation toward a jackpot is shown can be prevented in the plurality of notice performances executed during one variation performance, thus suppressing the loss of player's interest.SELECTED DRAWING: Figure 36
