keno is a game of chance played by many people all around the world. It originated in China over 1200 years ago and was popularized in the West during the 19th century.
This game is played with a ticket that consists of 81 numbers, 18 of which are visible to players. Players place bets on individual numbers or on groups of them, cover all or part of the ticket, or buy more tickets.
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.
