Keno is an online lottery-style game of chance. It is one of the oldest games found in casinos and has been played in its current form since the 19th century. The game is based on the Chinese lottery game of Keno, where players must select a set of numbers (or spots) from a pool of 80 numbers. Players must then guess which of the numbers will be drawn. Depending on where it is being played the game is sometimes referred to as hazaar ("thousands" in Arabic).
In Saudi Arabia, Keno is a popular game for Islamists who aren’t able to gamble with real money, as it is against their religion. As such it has become popular as an online game with websites dedicated to it.
