A gaming machine is provided, including a display, a credit input device, a non-transitory memory, and a processor. The display is configurable to selectively present a centrally determined game and a non-centrally determined game. The credit input device is used to establish a credit balance for wagering on the centrally determined game and the non-centrally determined game. The non-transitory memory stores a centrally determined game engine and a non-centrally determined game engine. The processor is coupled to the non-transitory memory and the display, and is configured to select a game engine from the centrally determined game engine and the non-centrally determined game engine, and execute the selected game engine and a corresponding game.
