GAME MACHINE

PROBLEM TO BE SOLVED: To make players hopeful of a mission performance by carrying out the mission performance as a probability variation suggestion performance suggesting that a high probability condition is latent. SOLUTION: In processing at Step S753, by referring to a mission performance execution decision table, when the game condition is a probability variation condition, a decision to execute the mission success performance is made at a higher rate than when the game condition is a game condition other than the probability variation condition. Meanwhile, when the game condition is the game condition other than the probability variation condition, a decision to execute a mission failure performance is made at a higher rate than when the game condition is the probability variation condition. Consequently, either the execution of the mission success performance or the mission failure performance allows the latency of the probability variation condition to be suggested to players.
