Keno is a relatively simple lottery-style game, similar to bingo, which is played in both land-based and online casinos. Players select a set of numbers from a box, known as the Keno card, and the casino then draws 20 numbers from the Keno card. If the player has chosen a set of numbers that match the 20 numbers drawn by the casino, then the player wins a prize. The appeal of Keno lies in the excitement of playing the game and the large payouts available, with some progressive Keno games offering prizes in the millions.
