Abstract
A keno game method includes initially randomly selecting a predetermined number of keno numbers after the player has selected two or more keno numbered spots that the player hopes to match. For each numbered spot matched or "Hit" by the player during the base game, an additional keno number is randomly selected during the extra ball portion of the game. In one version, the quantity of additional keno numbers to be drawn is determined by the amount of "Hits" during only the initial draw of keno numbers. In another version, the quantity of additional keno numbers to be drawn is cumulative from the "Hits" achieved over both the initial draw of keno numbers and during any additional draws. An award is made to the player for the total number of "Hits" achieved during the round of the game and based on the amount wagered by the player. In another version, an award is made to the player for the total number of "Misses" achieved during the extra ball portion of the game and based on the amount wagered by the player.
