Abstract: A progressive gaming system is configured to run many progressive prizes on one central system. The relationship between progressive group and prize with a particular game is designed so that the odds and bet on a particular game need not be identical throughout a group. In one embodiment, prize definition is in terms of number of coins expected to be played between prize hits, independent of denomination, and minimum number of coins returned to players, regardless of odds or denominations. When a progressive game is designed, the coins bet and odds related to the logic of the game are verified as compatible with the prize definitions coins expected to be played between prize hits. The prize definition is used to validate an association between a particular game and a particular progressive prize. Preferably the event that triggers a progressive prize may be unrelated to the events on any game.
