PURPOSE: To provide a ball hitting game machine which can exercise an interesting game chateristic having a larger variation, by leaving the converting of probability to get 'HIT', to a contingency. CONSTITUTION: As a probability of getting 'HIT' of a normal design display device, a random number for probability variation is generated at first (Step S50), the random number is settled after a specific time passes (S52), the first specific value of the random number is decided (S54), and when it is a specific number, the game machine is set at a high probability condition (S56), and the number to get 'HIT' (the second specific value) is made in two numbers 3 and 8. When it is not the specific number, the number is set in a normal probability condition (S66), and the number to get 'HIT' is made only 3. Then, a random number for normal design is generated (S58 and S68), the random number is settled after a specific time passes (S60 and S 70), it is decided whether the random number is the second specific number or not (S62 and S72), and when the answer is YES, a normal motor-operated big prize is opened as 'HIT' (S64 and S74), and when the answer is NO, it is made as 'OUT', and the process is finished as it is. |
