PROBLEM TO BE SOLVED: To provide a game machine having a variable winning probability following a change in weather to prevent a reduction in customer acquisition rate in bad weather. SOLUTION: The game machine measures temperature and humidity after 30 minutes from the start of timing with a temperature sensor and a humidity sensor, and the weather condition is determined from the measurement result. When the weather condition is "fine", a third probability table is used for a lottery, when the weather condition is "cloudy", a second probability table is used, and when the weather condition is "rain", a first probability table is used. The first, second, and third probability tables have winning probabilities set stepwise for respective bonuses, so that the winning probability is allowed to be varied according to the change in weather condition. The winning provability of the third winning probability table is set higher than those of the other probability tables, so that the customer acquisition rate is increased even in bad weather when the number of players tends to be reduced, and the profit of a game parlor is also allowed to be increased.
