A gaming system is provided in which a plurality of gaming terminals have gaming outcomes that are provided in response to a game outcome seed sent, to the gaming terminals, from a central computer. The game outcome seeds are individualized in the sense that not all gaming terminals in the system use the same seed at the same time. Preferably, seeds are addressed to individual gaming terminals or groups of terminals. Seeds may be transmitted to terminals in response to seed requests output by terminals. In one approach, seeds are generated as needed and/or substantially continuously. In another approach, batches, pools or lists of seeds are generated and a seed request is responded to by drawing a seed from a pre-defined list, until the list is depleted, whereupon a new list or batch is generated. In one approach, one or more lists are generated for each type of game or pay table. Preferably game outcome seeds are associated with tags or other information which can be used for verifying game outcomes and/or avoiding errors or cheating.
