Slot machine having a plurality of game lines

Abstract

Symbol displaying windows are arranged in matrix and are combined to set game lines including three horizontal lines, three vertical lines, and two diagonal lines. An operation panel is provided with line buttons and bet buttons. When a game is played, one of the line buttons is depressed first to nominate the game lines. Successively, one of the bet buttons is depressed to bet coins on the nominated game lines. After that, a symbol row is rotated in each symbol displaying window. A number of the game lines to be nominated and a number of coins to be betted thereon are optionally selected by a player. Each of the line buttons and the bet buttons contains an LED for showing whether the corresponding button is operative or not.
