Almost all casinos have keno lounges, where numbered balls are forced out through an air blower to determine the winners.
In the live version, the player may mark anywhere from 1 through 20 numbers on a card that has 80 numbers arranged in eight rows of ten.
The player then takes the card to a keno writer and places a bet that the numbers selected will be among the 20 drawn in the next game.
After the 20 numbers are drawn, winning tickets are paid according to a table that varies from house to house. For example, a four-spot ticket with USD1 wagered might return the USD1 if two numbers hit, bring USD5 if three numbers hit, and pay USD120 if all four come in.
