Keno is quite similar to bingo and lottery and is one of the most popular games of chance which is offered in modern casinos and even in several state lotteries. In traditional casinos, a circular glass enclosure had been used for playing keno. This enclosure is known as a bubble and it contains 80 balls which determine the results of the draw.
How to play keno?
Every ball used in keno is imprinted with numbers ranging from 1 to 80. At the time of drawing, a blower will push air in the enclosure to mix up all the balls. The person in charge of drawing the balls will press a lever which will open a tube where the balls would be lifted one at a time. The callers will life up the balls and draw a total of 20 balls and record the numbers imprinted on them. The players will have to place a bet by marking a spot on their blank ticket which will have 80 numbers printed on time. After all the players have placed their bets, the casino will draw the 20 balls and announce the winning numbers.
In casinos there are several different versions of the game and the choices on the pay scale are known as paytables. Every casino has several different paytables and the players have to choose from these, each of these will have a different house edge. The house edge on keno paytables will range from 4% to as much as 66%.
History of Keno
It is believed that the word Keno had been derived from Latin or French. However, the game had first originated in China. According to legends the invention of the game had been responsible for saving an ancient city at the time of war. The game had been very popular and had helped to raise funds for building the Great Wall of China. However, using lotteries for funding the government had only been accepted in China in the 19th century.
The Chinese lottery named baige piao had been documented only in the 1847 when the license had been granted to operators by the Portuguese government. According to many, the results of the games had been sent to the nearby hamlets and villages through the carrier pigeons at the time which is how the lottery had been named so. The name baige piao kmeans white pigeon tickets in Cantonese.
In the earliest years, the game had been played in China using sheets on which Chinese characters had been printed. These characters had usually been the first 80 characters from the Thousand character classic. It was from these characters that the winning characters used to be selected. Over the years, the immigrants from China introduced the game to the west when they sailed the Pacific for building the railroad in the 19th century. The name of the game had then been westernized and changed.
Ever since then Keno has been widely popular in countries across the world. Today several state lotteries offer Keno tickets to the players for raising money for different government projects.
