PROBLEM TO BE SOLVED: To simplify signals to be transmitted from a main control means to a pattern fluctuation control means and to easily accelerate the diversification of the pattern fluctuation of a pattern fluctuation display means. SOLUTION: This pinball game machine is provided with the main control means 26 for controlling a game operation, the pattern fluctuation display means 21 for variably displaying one or plural patterns and the pattern fluctuation control means 36 for changing the pattern of the pattern fluctuation display means 21 for prescribed time and stopping it by the signal from the main control means 26 on condition that a pattern start means 14 detects a game ball. The pattern fluctuation display means 21 is constituted of a liquid crystal display means 13 capable of displaying a background image. The pattern fluctuation control means 36 is provided with a function for storing the plural kinds of pattern fluctuation pattern permutations composed by time-sequentially combining the plural kinds of fluctuation patterns by a prescribed permutation and the function for selecting the pattern fluctuation pattern permutation by a random number processing corresponding to a fluctuation instruction signal from the main control means 26 and controlling the fluctuation of the pattern according to the pattern fluctuation pattern permutation. |
