kenoOne of the worst games in the history of gambling, when it comes to high House Edge is definitely Keno. This is a game much like lottery, often played at modern casinos, and also offered as a game in some state lotteries.

A traditional land based Casino Keno Game uses a circular glass enclosure called a “bubble” containing 80 (or sometimes less) balls which determine the ball draw result. Each ball is imprinted with a number 1 through the number of balls in the glass.

During the ball draw, 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 computerized keno system calculates all wagers based on the numbers drawn.

Players make bets 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 full bets, the casino draws 20 balls (numbers) at random. Some casinos automatically call the ball draw at preset timed intervals regardless of whether or not players are waiting to place a wager.

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. 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.

This legendary game has so little probabilities of you (or anyone else for that matter) hitting the jackpot, that is considered a scam in most places of the world, and in others it is considered illegal gambling, which can take to jail the providers of the game. However in many countries western countries it is actually accepted as a normal part of the society and is played every week by a majority of the population. A example of this would be Southamerican country, Venezuela, in which a variation of the game called “Kino T├íchira” is played nation-wide every week and has been going on for several decades.

In many South American countries, the game is played nationwide, just like the lotto in the United States, and in these games there are rarely any winners. This demonstrates the incredibly high house edge this games has over the players, making it one of the worst Casino Games in the world. The average House Edge of a Keno Game is of around 35%, but some can go down to as little as 5%, but these are very rare games.
