Keno is a lottery-style game that originated in China. It is a popular game in casinos, both land-based and online. The game is very simple—players choose numbers from a board and wait for a draw to take place, in which the player must correctly match their numbers to those drawn from the board in order to win.
Keno games come in many variations, with some offering larger prizes for matching more numbers, while others offer smaller prizes for matching fewer numbers. The number of numbers drawn and the payout structure will vary from game to game.
