The format was a four player game. Each player played two games of the four.
The top two scores earned a point. The bottom two scores scored zero points.
In order to win the match, a player needed 2 points.
So if one player had the top two scores, he wins the match because he earned 2 points.
If each player had one of the top two scores, then a second round was played because each player earned 1 point.
A two player, "Sudden Death", game was used to decide a tie after the first match.
The winner of the "Sudden Death" game wins the match.
