Keno dates back to ancient China and is considered to be one of the first gambling games. The rules of keno are not complicated and it’s pretty easy to play. Players have to bet on several numbers in the range of 1-80. They mark their choice, and then the ball machine or today, the RNG (random number generator) randomly draws 20 numbers. If the drawn numbers match the numbers marked on the player’s cards, they win. Today keno is usually played at an online casino, but some lotteries offer it in their package as well.

After Chinese workers promoted the game on the intercontinental railroad, keno began to attract numerous fans in America. It was quite popular in Texas in the 19th century and eventually found its way to Nevada, the worlds gambling capital. The popularity grew even more thanks to the profits they brought to casinos in Nevada. Other states have reformed laws to allow keno in their casinos. With a few rule changes, keno quickly found its way into American culture. Today it is popular in the United States as well as in Europe.
