» Keno Lottery Paytebles

Keno is a lottery-like or bingo-like gambling game played at modern casinos. The parts of a keno game are a circular glass enclosure called a "bubble" and 80 ping pong-like balls which determine the balldraw result. Each ball has a number (from 1 to 80) imprinted on it. A blower is used to push air into the bubble and mix the balls during the balldraw. A lever opening a tube is pressed by a "caller" and then the balls lift one at a time into a "V" shaped tube called the "rabbit ears". The caller and a "verifier" are used to record each of 20 balls drawn, and the computerized keno system is used to calculate all wagers based on the numbers drawn.
Players wager by marking an "X" over the "spot" choices on a blank keno ticket form with 80 numbered selection boxes (1 to 80). After all players successfully place their wagers, the casino draws 20 balls (numbers) at random.
"Paytables" are series of pay scale choices that are set by the casino. The players payout depends on how many numbers drawn match the numbers selected on the ticket. Players will find a wide variation of keno paytables from casino to casino and a large deviation in the house edge set for each of those paytables. Two identical keno paytables can hardly be found.
The house edge can vary from less than 4% to 66%.
