PROBLEM TO BE SOLVED: To increase amusement in pachinko games by varying the number of prize balls obtained by big-win operation and playing games full of variety. SOLUTION: After a plurality of rows of patterns such as numbers and symbols are each varied and displayed on a pattern varying display 2 in such a way as to flow in dynamic images by the prize-winning of a hit ball in an actuating prize-winning opening 5, the variation of the display rows are each halted with time differences. In the case that the patterns halted in the display rows are all the same after a state (a ready-to-win state in the following) in which the other display rows are already halted in the same patterns while only the last one row is still varying, a big win is achieved to bring a variable prize-winning device 7 into a continuous open state. The continuous open state is repeated until a predetermined final round is reached under condition that hit balls win prizes in a continuous prize-winning opening 9 provided in the variable prize-winning device in the pachinko game machine. A round number (a maximum round number in the following) by which the variable prize- winning device can be continuously open is displayed on the pattern varying display 2, etc., so that a game player sees it, and the maximum round number is changed in the case that all the patterns halted after the ready-to-win state are not the same.
