Page "Keno" Paragraph 1

Players wager by marking an " S " over the " spot " choices on a blank keno ticket form with 80 numbered selection boxes ( 1 to 80 ).

After all players successfully place their wagers, the casino draws 20 balls ( numbers ) at random.

Some casinos automatically call the ball draw at preset timed intervals regardless of whether or not players are waiting to place a wager.
