<p>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 individual pattern probabilities included in each pattern set combine to produce the desired probability of the prize level with which the pattern set is associated. In this way, a desired prize distribution may be used in a bingo-type game.</p> |
