Abstract: A random switching game engine for wagering games provides the advantage of switching between game engines in response to a triggering event. The switch engine controls which game engine will present a wagering game to the player. The different game engines may have different odds for presenting a winning outcome to a player. After a triggering event has occurred the switch game engine may utilize a random number generator to randomly determine whether a switch between game engines should occur. The triggering event may comprise the start of a game or any other event. A switch game engine may perform the switch by activating one of multiple game engines. The wagering game may be presented according to the same rules, but with different odds of receiving a winning outcome, to prevent a player from noticing that a switch between game engines has occurred, or different games may be presented.
