Abstract: A gaming system is disclosed wherein an outcome probability is determined for each of a number of possible outcomes achievable in a wagering game. Different subsets are then associated with each different prize level in a desired prize distribution. The possible outcomes and their respective probability are assigned or mapped to the different subsets so that the probability of achieving a possible outcome included in a subset comprises a value approximating the desired probability of an award of the prize level with which the subset is associated.

Abstract: A pattern probability (302) is determined for each of a number of target patterns (301) achievable in a bingo-type game. Each pattern probability (302) comprises a probability of achieving the respective target pattern (301) in the bingo-type game. Different pattern sets are then associated with each different prize level in a desired prize distribution. The target patterns (301) and their respective pattern probabilities (302) are assigned or mapped to the different pattern sets so that the probability of achieving any target pattern included in a pattern set comprises a value approximating the desired probability of the prize level with which the pattern set is associated.

Abstract: A method includes determining a pattern probability for each of a number of target patterns achievable in a bingo-type game. Each pattern probability comprises a probability of achieving the respective target pattern in the bingo-type game. The method further includes associating or mapping different pattern sets to each different prize level in a desired prize distribution. The target patterns and their respective pattern probabilities are assigned or mapped to the different pattern sets so that the individual pattern probabilities included in each pattern set add up to the desired probability of the prize level with which the pattern set is associated.

Abstract: A method according to the invention includes determining a pattern probability for each of a number of target patterns achievable in a bingo-type game. Each pattern probability comprises a probability of achieving the respective target pattern in the bingo-type game. The method next includes associating or mapping different pattern sets to each different prize level in a desired prize distribution. The target patterns and their respective pattern probabilities are assigned or mapped to the different pattern sets so that the individual pattern probabilities included in each pattern set add up to the desired probability of the prize level with which the pattern set is associated.
