Abstract
A random prize awarding system associated with a gaming console is provided in which the gaming console is arranged to play a first game or a second game, the first game being a standard game normally offered on the console and the second game being a jackpot game offered for play when the player has achieved a trigger condition where the trigger means is arranged to test for the trigger condition and to initiate an instance of the second game when the trigger condition occurs. The second game is divided into a plurality of sub-games, each having an incremental prize such that a sum of the un-won incremental prizes equals the total currently available jackpot prize value of the second game. The player is awarded each sub-game after the first, only if the incremental prize was won in the previous sub-game. The jackpot prize value being decremented by the incremental prize value awarded with the occurrence of each winning sub-game.
