Playing Keno is incredibly simple as players only have to place a bet and select a few numbers. You can choose any 3 numbers in the number range of 1 to 80. Once players have done this, the casino selects 20 numbers at random from the same number range. If any of the numbers chosen by players match the numbers randomly drawn by the software, players will get a payout. If not, players simply have to place another bet and try again.
