Keno may be the most familiar game in the casino because it so closely resembles the state lotteries that many people play. The object of keno is to choose one or more numbers out of a field of 1 to 80 that match the numbers drawn during a race or a series of races. Payouts are determined by a number of factors, including how many of your numbers match the drawn numbers, how much you wagered, and whether you wagered for the regular rate or a special rate. Keno is strictly a game of chance, which means there is no particular strategy or method of play that will affect the odds of winning.
