The word keno has French or Latin roots (Fr. quine "five winning numbers", L. quini "five each"), but it originated in ancient China. Keno is a simple and famous lottery-like game where players have a chance to win big money making a relatively small bet. It is considered to be one of the most engaging online lottery games. There is no human factor, nor dealer. Instead, there is a high quality and perfectly developed ball machine which works as a random number generator. The game is a 24/7 game, ongoing and available to people from all over the world which means an operator can receive bets around the clock.
