Keno is a lottery-style game, similar to bingo, in which players select a set of numbers and then wait for a matching set of numbers to be drawn out of a pool. In Portugal, Keno can be played at mobile casinos, both online and at physical venues. To play Keno, players must pick a minimum of two numbers and a maximum of ten numbers. The numbers can be from 1 to 80, and they must be chosen without repeating any number. After the numbers are chosen, the player must select a bet amount, which is the total amount the player is willing to wager.
Once the player's numbers and bet amount are selected, the game will begin. The computer or the game host will then draw twenty numbers from the selection pool. The goal of the game is for the player to match as many of their chosen numbers as possible to the ones drawn from the pool. Depending on the number of matches, the player will receive a corresponding payout.
