PROBLEM TO BE SOLVED: To provide a pinball game machine which properly operates even when a plurality of pattern start ports are provided. SOLUTION: The Pachinko game machine 2 carries out a drawing process as to whether or not an advantageous state for a player is generated in accordance with a value of a random number generating counter 61, when a game ball wins a prize in the pattern start ports 17A and 17B. The drawing process is carried out (S21, S22) for each prize winning in a periodical execution part which repeatedly executes the drawing processes at intervals of prescribed time P. An updating interval of the random number generating counter 61 is set to 1/2 times as long as the prescribed time P or shorter. COPYRIGHT: (C)2011,JPO&INPIT
