Keno is one of the oldest gambling games known to mankind. It is believed that the game that is an ancestor of keno originated in Ancient China, so that keno can be considered to be one of the numerous inventions of ready-witted Chinese people.
Despite the fact that Keno has a very high house edge (compared to blackjack, poker or video), thousands of fans play it worldwide daily. One of the most convenient virtual versions of keno was manufactured by Microgaming.
