PROBLEM TO BE SOLVED: To improve taste of a game by preventing a specific performance from getting monotonous.SOLUTION: In a variable display of decoration symbols based on an operation-start condition established when a game ball enters a variable winning ball device 15 during an open state, a game machine determines whether or not executing a specific performance and executes the specific performance during the variable display of the decoration symbols. The game machine can controls the variable winning ball device 15 in a first open state for changing the variable winning ball device into an open state for a first period, and a second open state for changing it into the open state for a second period different from the first period. The game machine determines to execute the specific performance at different ratios between the variable display of decoration symbols based on the operation-start condition established when the game ball enters the variable winning ball device 15 during the first open state and the variable display of the decoration symbols based on the establishment of the operation-start condition established when the game ball enters the variable winning ball device 15 during the second open state. |
