9-Point Ladder System

Important: A single 8-game pro set must be used for all matches for this system to work properly. If a match is tied at 8-8, a tiebreaker must be used to determine the winner. The resulting score should be recorded as 9-8 victory. There are no ties in tennis, one player must achieve a score of at least 8 games (9 for tiebreakers) to be declared the winner. If the match is not completed, do not record the score on tennisengine.com.


  • If the winner is higher ranked he receives 9 points added to his previous point value.
  • If the winner is lower ranked, his previous point value is replaced by the value of his opponent's points - plus 9 points, thus "leap-frogging" his opponent..
  • The loser receives 1 point for each game that he wins.

This ladder design includes the most important feature of a traditional ladder, i.e. when you beat a player you move into a position above him. But unlike a traditional ladder, the loser receives a reward for his effort that is proportional to the performance of that effort. Conceivably, the loser may earn up to 8 points by losing the pro-set match in a tiebreaker (9-8).

Ladder rankings are determined entirely by performance, while stimulating play in two important ways.

  1. A strong player can move to the top in one match but will surely be passed by others if he doesn't keep active. This prevents stagnation in the ladder.
  2. A losing effort gets rewarded for performance, but not enough to allow a player to maintain a high position simply by playing a lot of matches, a consistant problem in point accrual systems. Every losing effort also produces a higher-ranked winner. Winning is rewarded considerably more than just participating.

This ladder system gives a good credible ranking in a flexible and dynamic format. Anyone on the ladder can challenge anyone else, up or down, providing motivation for all players to participate. Anyone can rise as high in the rankings as performance justifies, yet no one can sit on their laurels.

The online league is updated every time a match is entered.

Please note: If a player is involved in multiple matches in a single calendar day, each match bonus is credited - but only as if each match was the only match that member played on that given day. In other words, "leap-frog" bonuses are not awarded to players who subsequently beat that player on the same day that he achieved a "leap-frog" bonus.
