PROBLEM TO BE SOLVED: To provide a game machine which enables players to be notified of the current probability state to help them break out of a hopeless rut they have been in. SOLUTION: After the end of the jackpot game, the game machine controls to repeat the lottery for the jackpot game under either the high-probability state (variable-probability state) with a higher probability of shifting to the jackpot game or the low-probability state with the probability lower than the high-probability state as each winning occurs. In the lottery for the jackpot game in the high-probability state, an alteration lottery to the low-probability state is conducted and with the hit on the alteration lottery, it is controlled to make the alteration (drop) to the low-probability state from the high-probability state. After the end of the jackpot game won by the lottery under the low-probability state, with the hit on the alteration lottery (dropping lottery), it is controlled to execute "time shortening operation" for the extension of the time of opening a wing member.
