One of the fascinations of a study of gambling over a long period of our history is our enduring love of gambling on numbers. An excellent example of this is the game of Bingo, and although many of the Bingo halls and clubs in our towns and cities have been struggling of late the game itself remains popular. Nearly all the major online casino gambling sites offer various forms of Bingo as part of their range of casino gambling games, and most also have a variety of alternative games which involve gambling on numbers. There are of course a number of games based on the principle of the lotteries, but there are also a few new numbers gambling games such as Keno. Keno is becoming very popular online and is best described as a cross between a lottery and bingo. Keno gamblers are required to select up to 15 numbers from 1 to 80, after which a Random Numbers Generator produces 20 winning numbers each round. Winnings depend on both the initial number of selections and the number of correct winning numbers selected. Clearly the winning odds vary according to the level of risk the Keno gambler has chosen with their initial selections. At Paddy Power for instance matching 5 numbers from 15 selections pays 2/1, whereas 5 correct numbers from just 10 initial selections raises the winning odds to 8/1. We should point out that the winning odds on Keno do vary slightly from one online casino gambling site to another so check the odds before you start to play for real. Gambling on Keno can sound a little complicated, but the Keno graphics clearly show how the odds are changing as you make more initial selections, and most online casinos offer gambling on Keno in Free Play mode so that new players can give it a try before gambling real money. It’s great fun so why not give Keno a try.
