The players decide on who first becomes the “scorer” and the “stopper.” They may do this anyhow but competing on who throws his dart closest to the bullseye is still the fairer way to do it. The stopper is the one who shoots first. He stops the numbers on the board with his darts. Stopped numbers don’t count for points when hit by the scorer.

There are two parts to be played in every turn. The first part is when the stopper stops numbers on the board and then the scorer shoots for scores. The second part is the reverse. The scorer becomes the stopper while the stopper becomes the scorer.

Standard scoring applies for the game.

A round for the game ends when all of the numbers have already been stopped. Since the game is played in two rounds, there is still chance for a losing player in the first round to make subsequent progress. Scores are accumulated from the first to the second round to determine the winner.
