Keno is a lottery-style game that originated in China around 200 BC. Played in Guatemala and other parts of the world, this game is quite popular in the country’s mobile casino sector. The rules of playing mobile Keno in Guatemala are very similar to the game's rules elsewhere; the game features 80 balls with numbers from one to 80, and players have to choose up to 20 numbers. The more numbers matched by the player, the higher the payout will be. The game is usually played with a virtual card, which shows the 80 numbers and a few blank spaces for players to mark their numbers of choice. The game's outcome is determined by the random selection of numbers, done through a draw.
