Lotto Variant is a term used to describe two popular lottery-style games: Keno and Beano. Keno is a game in which players select a set of numbers, usually between 1 and 80, and then wait for the draw to see if their numbers match those drawn. Beano is similar to Keno, but instead of numbers, players select beans with numbers on them. Both games are based on luck and offer players the chance to win large prizes.
