Keno is a lottery-style game of chance, played with numbered balls that are drawn randomly from a container. Players select a certain number of numbers from the range of possible numbers, usually up to 10, and mark them on a ticket. In some variations of the game, players also select the order of numbers in their selections. After all players have made their selections, the draw begins. In a mobile version of Keno, the draws are conducted virtually through a Random Number Generator.
Once the numbers are drawn, the payouts for each selection vary depending on how many numbers are picked and how many numbers are matched from the draw. At mobile casinos in Serbia, the most common payout is 1:1 for 1 correct number, 2:1 for 2 correct numbers and 5:1 for 3 correct numbers. Other payouts depend on the specific game.
