One of the oldest games in casinos that still exist today is Keno. Would you believe that the game appeared in China in 187 BC? Keno was introduced by Cheung Leung of Han Dynasty, when his city was at war for several years, and started running out of money and supplies.Cheung Leung conceptualized an idea that would both fund his army and would not add extra taxation on his citizens, the game enabled Cheung Leung to acquire sufficient money in order to finance the war. It is then called as the “Game of the White Pigeon”, because with lack of communication around the countryside, the news of successes and losses is relayed by a dove.The game invented by Cheung Leung is somewhat similar to the modern game of Keno we are playing today. The game of Keno is a lottery game similar to bingo, in the early times lottery is strictly prohibited but horse races is legal, so a game of Keno is called a “race” to conceal it’s true identity.It is usually played in lounges at the casinos specifically allocated for the game. To keep the players informed of the winning numbers, television monitors are spread all over the casino halls.You can also enjoy playing Keno in the internet just visit the most trusted online casino sites that provide you a list of the best casino to maximize your gaming experience, or play the video version of Keno, the coin operated slots-like machines, that applies the same principle and similar rules but the results is much faster.To start the game, a player must select a minimum of but not more than 10 numbers between 1 to 80. “Spot” is called to each selection, so if you select 10 numbers you are playing the 10 Spot game.
