For many years the most popular form of gambling amongst the general population of Ireland was Bingo. Bingo clubs could be found in almost every major town and city and were a centre for social gathering and a good night out for a great many people. Unfortunately many of these Bingo clubs have since closed, with both the recession and the smoking ban shouldering the blame, but gambling on numbers remains a very popular activity. Nowadays the online casinos tend to be the leaders in providing the casino games which satisfy our desire to gamble on numbers, including of course Bingo but also many other casino games which operate on a similar principle. One of these new casino games available at most of the major online casinos is Keno. We have included a description of how to play Keno in our individual casino games pages, but the idea is to select up to twenty numbers from 1 to 80, and hope to match as many as possible with twenty numbers then selected randomly by the online casino RNG. Winnings obviously depend on the number of correct selections, but also on the number of numbers chosen at the beginning of the game. Keno players can choose to select less than twenty numbers initially, which automatically increases the winnings on every correct selection. For example, if the Keno player selects only ten numbers at the start of the game the chances of matching say five of them is clearly less than it would be to match five from twenty, but the pay-out for each number matched is much higher. It is not as complicated as it sounds, because the Keno graphics on the online casino show clearly how the winning odds are changing as more selections are made, enabling the Keno player to easily control the risk they are taking. Keno is a fun casino game and well worth a try particularly for Bingo fans who enjoy gambling on numbers.
