<p>The gaming machine has pref. three rotating elements driven by a stepping motor and provided with symbols deciding gain or loss. A starting push-button is allocated to each rotating element, or one common pusg-button is allocated to all of them. A control device, e.g. a microprocessor, determines the running time of the rotating elements. An element is operated by the starting push-button (1) and has two contact sets (7, 8) delivering consecutively one pulse each. The control device imparts to the rotatable elements different speeds or different times of rotation depending on the speed of the operation of the push-button.</p> |
