To provide a game machine, even if communications between control parts are one-way, capable of relating performances executed by the respective control parts and executing the performances without a feeling of strangeness.

When a player internally wins a pressing order bell 2-2 while a game state in a sub side is a mode B1, the game machine executes a notification (a navigation that a main performance 2 is executable) relating to a stop operation that makes the main performance 2 executable and, when the player executes the stop operation according to the notification, executes the main performance 2 that executes a reel action after an operation of a start lever in or after a next game of the game. Alternatively, when the player internally wins the pressing order bell 2-2 while a mode performance B2 that should not be executed concurrently with the main performance 2 is executed in the mode B2, the game machine executes a notification (a navigation that the main performance 2 is inexecutable) relating to a stop operation that makes the main performance 2 inexecutable and, when the player executes the stop operation according to the notification, does not execute the main performance 2 after the operation of the start lever in and after the next game of the game.
