Keno is a lottery style game, in which players must choose a certain amount of numbers from a larger selection offered by the house. The more numbers a player chooses and the more numbers that are matched, the higher the payout. Depending on the specific online casino, the offer of numbers might vary. In American keno, players are required to pick an average of four numbers, but for Chinese players the number of picks required is usually lower, with the average being around two.
In some cases the player can manually choose their numbers, while other games feature an automated play option where the numbers are chosen randomly. Players are then expected to make a bet and wait for the game to draw the numbers. Bets usually range from 1-10 with smaller amounts having higher chances of matching but consequentially lower payouts.
