Keno Game

Keno is a game of chance, which is very much like bingo or a lottery. In fact, it is offered as a state lottery game in some countries. The game is played with a circular glass ball, called a bubble that contains 80 small balls with numbers from 1 to 80. The blower inside the ball pushes air into the bubble to mix the balls. When the caller opens the V shaped tube, called "rabbit ears" the balls start coming out. The game calls 20 winning balls and the computerized system counts the wagers placed on the result.

History of the game

Keno ticket
Keno is a game for those
who love high level of adrenaline for low pay.

The game originated in China, where it first was used as a way to gather funds for building the Great Wall. The results of the game were sent to small cities and close villages by carrier pigeons, which is why the game was called "white pigeon tickets". The game was then introduced by Chinese immigrants when they came to the West as a way to help build the American trans-continental railroad in the 19th century.

The name of the game means quini - five each in Latin.


The wagers are made before the game begins by placing an x on the number on a blank keno ticket. As soon as all players have placed their wagers, the game begins. Some casinos have a set time when the balls are drawn regardless of whether (not all the players have put their wagers.

Each casino has its own paytable, and after all 20 balls have come out, the casino pays out the winnings based upon the number of balls the player has guessed. The house edge differs from one casino to another, the main difference being the type of the game and it can vary from 4% to 66%.

The odds of Keno depend upon the number of balls in the game and the quantity of numbers that the players can bet on. The biggest win is paid for hitting the biggest quantity of numbers. However, in some variations you are to guess zero numbers from the winning combination to win most.

The chance of hitting all 20 numbers on a ticket with 20 spots is 1 in 3,535,316,142,212,180,000 (3.5 quintillion). If you could lay all these tickets end to end, the line would stretch to the Milky Way galaxy, and there would only be one winning ticket. Another way to describe the odds is - if every person alive today played one game every second of his/her life, there would be 20 jackpot winning tickets per day.
