Slot Machine

Abstract

A slot machine according to the present invention includes a symbol matrix display area, second reels having second symbols arranged in a superimposed manner on first symbols of first reels, and a processor for controlling rotation of the first and second reels. The plurality of first reels each has an independent rotation axis. Rotation axis of each second reel is positioned closer to a rear side compared to that of each first reel when viewed from the symbol matrix display area. The processor awards a prize in the case where a combination of the first symbols of the first reels rearranged in the symbol matrix display area and the second symbols of the second reels rearranged in a superimposed manner on the first symbols of the first reels is a winning combination on an activated line in a column, row, or diagonal direction.
