The players must prepare balls or pieces of paper numbered one to twenty. The balls or pieces of paper are then placed in a container from which they can be scrambled and drawn. An umpire is appointed to draw the balls.

Every player is allowed only one dart in every turn. Each time a number is drawn, he tries to score that number on the board. He should be able to throw six of that number with the least throws for him to call “bingo” and collect the prize.
