Keno is a relative newcomer to the online casino game world, and will most usually be found amongst the "other games". The game has existed in some form in china for centuries; there are traditions linking an early form of the game with Cheung Leung of the Chinese Han Dynasty which would date it to over 2000 years ago. Keno is a kind of lottery game that that involves 80 balls and 80 numbers. The aim of the game is to predict the numbers that will be selected of the 80 by marking them on your keno card. The balls are then selected and winnings depend on the number of correct guesses you made. There will be differences between online casinos as to how many numbers you can bet on, and the payouts will be different, however basically the more numbers you get right, the more money you win.

Keno, like slots and roulette requires very little knowledge, and no strategy which makes it very attractive. However, unlike slots one does have the sense, and it's a real one, of being able to control your outcome and thus your fate in keno, and unlike roulette and slots the game lasts a little longer which means that the entertainment is more drawn out and you play for more time for less money.
