PURPOSE:To obtain a game machine which enables the altering of the proceeding of a game by a method wherein brain waves of a player operating the game machine is measured to estimate a mental control value of the player and a capacity value of the player is regulated to control own mental condition of the player. CONSTITUTION:When a key input device 2 is operated by a player 1, a computer 4 controls an image display device 6 and an acoustic output device 7 separately according to a software 5 to execute a game. Here, brain waves of the player 1 are measured with a brain wave measuring device 3. The computer 4 computes the value of mental control of the player 1 with an arithmetic device 42 based on a measuring data of the brain waves measuring device 3 and the results of the preceding measurement of brain waves stored in a memory 41 while a capacity value of the player during the game is controlled with a controller 43. This enables the realization of a game machine which allows the player 1 to change the progress of the game by controlling his own mental condition.
