How to play keno :-
Keno is a lottery or bingo betting game often played at modern casinos, and is also offered as a game in some state lotteries. A customary live casino keno game uses a circular glass enclosure called a “bubble” containing 80 balls which determine the balldraw result. Each ball is embossed with a number 1 through 80. through the balldraw, a blower pushes air into the bubble and mixes the balls. A “caller” presses a lever opening a tube, where the balls lift one at a time into a “V” shaped tube called the “rabbit ears”. The caller and a “verifier” record each of 20 balls drawn, and the automated keno system calculates all wagers based on the numbers drawn. Players wager by marking an “S” 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. Some casinos mechanically call the balldraw at preset timed intervals despite of whether or not players are waiting to place a wager.
