PROBLEM TO BE SOLVED: To provide a so-called right awarding game machine, capable of making a player thrilled and excited sufficiently about acquiring rights. SOLUTION: In the game machine, a display game is executed based on entrance of balls into a starting slot. If a winning display such as '77' appears and a first condition is satisfied, a condition device (blades) of a variable winning device, which is normally closed, is opened for a few seconds. If a prescribed number of balls enter the variable winning device during the period, a second condition is satisfied and a right is generated; a large winning slot is opened and the condition is set so that a winning display will appear in the next display game. The opening angle and opening period of the condition device and the upper limit number of balls per minute to be shot while the condition device is opened are varied according to the kind of the appearing winning display. Further, how much the probability of appearance of a winning display should be increased in and after the next display game is varied according to the number of balls entering the variable winning device while the condition device is opened. In addition, correlation between the kind of a winning display to appear and the opening angle of the conditional device, etc., is varied.
