Abstract: 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 variable probability 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 often significantly greater than 50% although the overall hold percentage of the game remains below 100%.

Abstract: An electronic video gaming machine for playing multiple games is set forth. The gaming machine includes a first set of game elements for playing a game having a plurality of possible game outcomes. A first game outcome is selected from a plurality of possible game outcomes including at least one predetermined carry-over outcome. The carry-over outcome occurring in the first game outcome is automatically duplicated by the processor into at least one other game outcome. Game elements of the first game outcome are also manually selectable by a player and the selected game elements are duplicated by the processor into at least one other game outcome. Multiple game elements are shown on game boards arranged in a stack and displayed on a touch screen. The stack includes a top end and a bottom end and each game board has a face on which a single game is displayed.
