In various embodiments a casino has the flexibility to download games from a central controller to the gaming devices on the casino floor. The success of various games is periodically monitored. If a game is successful, as measured by its profitability or by some other success metric, then the game may be downloaded automatically to additional gaming devices. If a game is unsuccessful, then the game may be replaced on a gaming device with a new download. In this way, the types and quantities of different games present on a casino floor may be varied in real time based on their popularity.
