Abstract
A pool of game outcomes is generated on a smart card that is associated with a gaming machine. The pool of game outcomes is identical to a previously generated pool of game outcomes. A seed is created and a pool of game outcomes is generated using the seed, a pseudorandom number generator (pRNG), game rules, and a pool size. The seed, a game identifier associated with the game rules, and the pool size are stored in a database that is remote from the smart card. The seed, the game identifier, and the pool size are usable for audit purposes to recreate the pool of game outcomes using the same pRNG and the same game rules that are used to generate the original pool of game outcomes. A memory of the smart card associated with the gaming machine is loaded with the seed. The smart card includes same pRNG that is used to generate the original pool of game outcomes. Game outcomes are then generated during game play of the gaming machine using the seed in the memory of the smart card, the pRNG in the smart card, and the game rules used to generate the original pool of game outcomes. The game outcomes generated during game play are identical to the generated original pool of game outcomes.
