A lottery-like or bingo-like gambling game played at modern casinos is called keno. There is a circular glass enclosure called a "bubble" containing 80 ping pong-like balls which determine the balldraw result in keno. There are numbers from 1 to 80 on each keno ball. During the balldraw, a blower pushes air into the bubble and mixes the balls. 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". Each of 20 balls drawn are recorded by the caller and a "verifier" and all wagers based on the numbers drawn are calculated by the computerized keno system.
Players mark an "X" over the "spot" choices on a blank keno ticket form containing numbers from 1 to 80. After all players successfully place their wagers, the casino draws 20 balls (numbers) at random.
Each casino sets its own series of pay scale choices called "paytables". The player is paid based on how many numbers drawn match the numbers selected on the ticket and according to the paytable selected with regard to the wager amount. Keno paytables and the house edge set for each of those paytables vary greatly from casino to casino. Two identical keno paytables can hardly be found.
The house edge can vary from less than 4% to 66%.
