Keno is a game which is very similar to a lottery. Like a lottery, Keno gives players the chance to win large jackpots from a relatively small stake. There are, however, a number of differences between the two games. Keno games start more frequently than lottery games with dedicated Keno sites starting new games at regular intervals, usually every 20 minutes. Most online casinos also offer Keno and are ready to start a new game whenever a player wants.

Keno uses 80 balls, numbered from 1 to 80, 20 of which are randomly selected during each game. The object of the game is to guess some of the numbers which will be drawn. The player does this by marking their chosen numbers on the 'Keno ticket'. A minimum of 3 numbers and a maximum of 10 numbers can be selected per game. Each selection of numbers is known as a 'spot', such as a '3 spot' for 3 numbers and a '10 spot' for 10 numbers. When the players have selected their numbers, they must choose how many times they want to play and how much they wish to gamble.

Of the 20 numbers that are randomly drawn, the more the player correctly guesses, the more money they win. However, the winning odds vary according to the amount of numbers that the player marked on their Keno ticket. For example, if the player only choose 3 numbers, the odds of guessing 2 numbers is 5 to 1 and 3 numbers, 25 to 1. If the player choose the maximum of 10 numbers then the minimum winning odds for 5 numbers is 5 to 1 and the odds of getting all 10 numbers is 10,000 to 1.

In truth, there are no real Keno playing strategies. This game is all about luck, however, the stakes are small and the jackpots can be huge. The following is a Keno odds table outlining winnings according to the amount wagered and the quantity of numbers played. Please note that all figures are given in US Dollars.
