`
`ABSTRACT
`(67)
`Adisclosed gaming machineis designed to execute a modular
`gaming software architecture. A plurality ofgaming software
`modules may be loaded into RAM on the gaming machine
`and executed to play a game of chance. Manyof the gaming
`software modules are designed to communicate via applica-
`tion program interfaces so that the logic in many ofthe gam-
`ing software modules may be designed independently ofeach
`other. In particular, the modular gamingsoftware architecture
`allows a gameflow software module used to generate a game
`of chance on the gaming machine to be decoupled from a
`gamepresentation software module usedto present the game
`chance. Thus, a group of games may be designed where the
`games share a common game flow sofiware module but use
`different game presentation software modules to change the
`look and feel of the game.
