Any examination into the history of gambling in Ireland must include reference to the game of Bingo. Although our Bingo clubs are reported to be in decline there is no doubt that gambling on numbers in the form of Bingo was by far the most popular game played by the general public. Now that we have access to online casinos with their ever expanding range of casino games, we find that Bingo still remains a popular choice for many online casino games players. This has encouraged the online casino software suppliers to introduce a number of other casino games which involve gambling on numbers, one of which is called Keno. Best described as a cross between a lottery and Bingo, the online casino game of Keno requires players to select up to twenty numbers from 1 to 80, and try to match as many of those numbers as possible with the twenty numbers which are then selected by a Random Number Generator or RNG. There is an extra twist to the game of Keno, which we have explained on our casino games pages, because the player has the option of choosing less than twenty numbers which then automatically increases the winnings for every number matched with the RNG selection. For example, if a player selects just ten numbers the chances of matching five of them is clearly less than matching five from twenty and the winnings are therefore correspondingly greater. Although this sounds a little complicated, the online casino graphics associated with playing Keno clearly show how the odds are changing as the player makes more selections. The online casino game of Keno is rapidly acquiring more and more fans because it is easy to play and is one of the few casino games which allows the player to choose how much risk they want to take and their own odds of winning. Why not give this fascinating online casino game a try, it really is good fun.
