Keno is a numbers game and is played on similar lines to bingo.
Except that in keno, players pick their own numbers.
Keno cards have 80 numbers and a player is free to choose a minimum of 1 and maximum of 20 numbers.
After that is done, the keno numbers are selected and the player marks on his card the ones which are selected that correspond to the numbers he chose.
The less numbers chosen, the more matches, the bigger the pay out.
The player also has to select how many games those keno numbers will be applicable for.
The pay out is based on the amount the player wagered and the amount of numbers he selected.
Keno winnings have to be claimed straight after the game otherwise they will be forfeited.
Because of this casinos allow players to play 20 games with those numbers which allows the player more time to redeem the winnings.
