Abstract (en)
A gaming machine is operated by a programmed micro-processor in which the first mode of operation, a basic gambling game, is implemented such as video poker or reel-type slot machine play. If bonus symbols are selected in the basic mode, a bonus mode is triggered. In the bonus mode the same or a different game is implemented by the micro-processor system employing a Bernoulli trial procedure in which the player continues to play and receive awards until a losing combination occurs. The hit rate for the bonus mode is greater than 50% although the overall pay out percentage of the game remains below 100%. <IMAGE> <IMAGE>
