Keno is a thrilling game that was first introduced in China around 200B.C. It came to the United States with the immigrants and over time evolved into the game you now see before you. The Keno game is played with a traditional 80-numbered ticket and 20 balls whose function is the same as in a standard lottery. The player marks from 1 to 15 spots on the ticket and is paid according to the numbers that roll out on the balls and the bet he or she chose. The five different ways to bet on a Keno ticket are discussed below. After each game you may choose to stay with the same spots you played (by clicking on REPEAT button) or pick new spots on the ticket. Different betting options are enabled as you place your marks, however you may not mark more than 15 spots on any one game.

"Bet "
        Option is enabled once you mark at least one spot on the Keno ticket. You are paid if one or more of the numbers you chose roll out on the balls. The following is a sample payoff tables for a $1.00 bet.

You are betting that top or bottom part of the ticket will have fewer spots than the opposite part. The payoff depends on how great that difference is. The following is a sample payoff for a $1.00 bet.
