Abstract: A main or base game has an associated bingo-type matching bonus game or event. The main or base game may have a winning outcome with an associated base award. Upon the occurrence of certain events, such as matches of symbols used in the main game, one or more bonus indicia, such as bingo balls, are generated. These bonus indicia are compared to a player's bonus indicia, such as bingo numbers on a player's bingo card, for matching. If one or more designated matches, such as matching patterns, are achieved, the player may be awarded a bonus event award.
