Abstract

Abstract A rapidly incrementing multiple progressive gaming system. One or more gaming controllers are coupled to a progressive controller. Coin drop and win information at each gaming controller is provided to and accumulated by the progressive controller. Meter amounts generated at the progressive controller are transmitted back to the gaming controllers to provide multiple continually incrementing progressive bonus values. Upon game win, all gaming controllers not in play are reset to an initial starting value. Gaming controllers in play during a win are allowed to complete play at a progressive bonus value as established at beginning of game play. Any additional wins generated during the completion interval are paid at this progressive bonus value. A current progressive value is provided to update the game controller either continually or upon game completion. The game payouts are frozen upon detection of the coin drop so that the player knows the value(s) being played for.
