PROBLEM TO BE SOLVED: To provide a game machine which can take a balance between advantage and disadvantage among players which drop to the low-probability state making them easily stuck in "hopeless rut" in a short time and those who are allowed to maintain the high probability state making them resist to falling into hopeless rut. SOLUTION: The game machine includes a game ball distribution means which distributes game balls selectively to a first game area or to a second game area, a game progress control means which controls the progress of games and a probability alteration lottery means which carries out an alteration lottery for determining whether alteration should be made to the low-probability state from the high-probability state when a variable display game containing an attached game is executed in the high-probability state. When an attached game continues prescribed times without the hit of the alteration lottery by the probability alteration lottery means, the game progress control means controls the game ball distribution means to enable the distribution of the game balls to the second game area during a prescribed period.
