Keno is a lottery-like game of chance with a low house edge. It is played on a grid of 81 numbers arranged in a rectangle, 25 on each side. The player selects some or all of those numbers, and then the keno balls are drawn from a separate pool of 80 balls to see which ones match the player’s selection. In one variant, if none of the player’s selected numbers are drawn, he or she wins second prize.
