Round Robin Format
Each player plays one or more games against each one of the other players. The player winning the most games wins the tournament. The player winning the second most number of games comes in second, etc.
Round Robin format is also called Block, and All-Play-All.
This format ranks the players in a fixed number of games.
Several players may win the same number of games, so a method of tie breaking is required.
Total net points is the most common tie breaker. A game score of 26-9 is +17 net points for the winner, and –17 net points for the loser. The sum of all the net points in all the games won or lost by a player is that player's total net points.
Total gross points is the most common second tie breaker — used in the unusual case when players are tied on both games and total net points. A game score of 26-9 is 26 gross points for the winner, and 9 gross points for the loser. The sum of all the gross points in all the games won or lost by a player is that player's total gross points.
Below, is a five-player double (each player playing every other player twice) Round Robin tournament. Player C comes in first place by winning six games. Players B and E each won five games, but Player E comes in second place with +61 total net points, and Player B comes in third place. Players A and D are tied in both total wins and total net points, so Player D comes in fourth place with 70 total gross points, and Player A comes in fifth place.
