Keno is an interesting game that may look like a lottery but it has its own rules. This game is widely available at Saudi Arabia's mobile casinos, with the aim of guessing the numbers the casino will randomly draw. The player has to purchase tickets and guess a set of numbers. For instance, the player can pick up to 10 (or more) numbers between 1 and 20, which are numbered balls in the game. After that, the player places a wager on the specific numbers he has chosen. The more numbers the player matches, the bigger the payout.
