Abstract
An online lottery game system and methodology involves, for each play of the game, a player choosing a number of player indicia from a field of the indicia. A subset of the indicia is randomly generated, and the player's indicia is compared to the subset to determine a winning game play. The number of indicia in the subsets is varied between different game plays such that a blend of the winning probabilities for each subset for all of the game plays produces a desired overall winning probability.
