Title: Slot machine
Inventor: OGURA TOSHIO
IPC: A63F5/04
Filed: 2017-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce a burden of a player.SOLUTION: When any of replays GR21-23 is won within one set of ART, a slot machine notifies of depressing order of six choices by a determination navigation performance in a period until it is identified that the ART is started. After it is identified that the ART is started, there is no necessity to determine correct depressing order of a determination symbol combination again. Consequently, during a period from when it is identified that the ART is started and an ART signal is externally output, until one set of ART is terminated, the slot machine notifies of depressing order of three choices by executing a normal navigation performance and notifies of only a first stop by which a special replay is won.SELECTED DRAWING: Figure 50
