The entertainment machine has a device for accepting and evaluating the value of tokens, symbol displays behind windows and a controller (19) contg.a win counter and random number generator which drives the display according to the win state. If there is a game extension state in the win counter a warning signal is fed by the controller to a further control device which deducts a certain amount from the win memory (26) and sends a signal allowing random symbol generation for a corresp. period. The generated symbols are displayed (2). ADVANTAGE - Enables charges to be paid to be determined separately from game extension.
