Many of the casino games played at online casinos rely on Random Number Generators to determine winning numbers, so we should not be surprised that most online casinos now offer a selection of pure numbers games. These online casino games obviously include lotteries and bingo, but for those gamblers who want something a little more interesting there is also the game of Keno. Keno is not a new game as such, and has been played in American casinos for many years, but the advent of online casinos has now brought Keno to the attention of online casino gamblers on this side of the Atlantic and it is rapidly establishing itself as a casino game of choice for many in Ireland and the UK. As with most of the other numbers games, Keno players are asked to select numbers from a grid, in this case up to twenty numbers from eighty, and the payout depends on how many of those numbers come up. The major difference between Keno and the other casino number games is that you can choose your level of risk and potential reward, by selecting as many numbers as you like, so if you decide to select only ten numbers your chances of winning are reduced, but each winning number will pay better odds. It sounds a bit complicated but after a few trial runs in the free play mode, you’ll quickly get the hang of it and the odds are clearly displayed on the graphic as you make your selections to help you decide how much risk you want to take. Once you have decided how many numbers you’re going to select, Keno is a very quick and easy casino game to play, and because you can play for small or large stakes depending on your budget, Keno is an online casino game with widespread appeal. Just one word of advice, the odds do vary slightly from one online casino to another so it is worth checking a few sites in free play mode before taking the plunge. Keno is good fun so give it a go.
