Date Dec. 28, 1989.An arrangement for a game playing device comprising a game playing apparatus which controls a prize delivering machinery (10), a feeding device (7) for a token (8) for starting the game playing apparatus against a payment, and a tuner (11) controlling the prize delivering machinery. The tuner improves the odds and the chances of winning a prize from a normal state in response to the operation of the game playing apparatus. In order that the tuner could be restored to the normal state by the player, the game playing device comprises a stop switch (13) which influences the feeding device for starting the game playing apparatus without payment and which is arranged to control the tuner in such a manner that the tuner is restored to the normal state when the operation of the game playing device does not affect the tuner or the prize delivering machinery, so that the player does not win a prize.
