Keno is a lottery-style game in which players may choose between one and twenty numbers out of a pool of eighty numbers. The game has its roots in China and was brought to the United States in the late 19th century. It is now a popular game in many countries, and its mobile versions are becoming increasingly popular in Brazil.
Players must select a minimum of one and a maximum of twenty numbers from a pool of eighty numbers and submit their ticket. The Brazilian keno game involves a round of twenty numbers being randomly chosen by the game. If the numbers drawn match the player's selections, they win. The amount of money won depends on the amount of numbers guessed correctly and the amount of money wagered.
