Two of the most common forms of gambling in this country are Bingo and of course the Lottery. Both are very easy to play and rely on matching a set of numbers drawn randomly. As you might expect the online casinos have not been slow to pick up on the popularity of numbers games, and you will find versions of Bingo and lottery games amongst the casino games offered on almost all the main online casino sites. But the online casinos have also introduced a selection of other numbers games to tempt us, one of which is called Keno and is proving very popular with many online casino games players. We have described the game of Keno in detail on our casino games pages, but the principle is very simple in that the player is required to select up to twenty numbers from 1 to 80, and the winnings are calculated based on the number of correct predictions and how many numbers were selected. The Keno player can therefore effectively choose what odds they wish to play for by reducing the number of selections. Clearly the chances of getting say 5 correct numbers from 20 is far greater than getting 5 correct numbers from 10 selections, and the pay-out from Keno reflects those odds. It sounds a little complicated but the online casinos make it easier by clearly showing on their casino graphics how the odds are changing as you increase the number of selections so that the Keno player is constantly updated as they choose more numbers. It is easy to understand why Keno has become so popular with online casino games players because there are not many casino games which allow the player to select their own odds and degree of risk. Don’t forget you can also play Keno in Free Play mode on most online casino sites until you get to know how it works.
