Tiebreakers: ELO, Buchholz, Sonneborn-Berger

How Slams decides the standings when points are level: game difference, set difference and rating per format, plus what ELO, Buchholz and Sonneborn-Berger mean.

2 min read · Updated 18 July 2026

The order in a Slams standings is almost always determined by competition points. If two teams or players are level on points, Slams uses a series of tiebreakers to settle the tie. Which criteria apply depends on the format you are playing.

First: the points

In most formats a won match earns 3 points, a draw 1 point and a loss 0 points. In a league you can set this points system yourself (for example 2 points for a win) in the part's settings. In an Americano or Mexicano it works differently: there your points are simply the total number of games you have won.

The tiebreakers per format

If participants are level on points, Slams looks in turn at:

  • Tournament (group): game difference (games won minus games lost), then the number of games won.
  • League: game difference, then set difference, then the number of games won.
  • Ladder: the rating of the team. On the KNLTB scale a lower rating is better, so the strongest playing level is at the top.
  • Team Clash: set difference, then the number of matches won.
  • Americano and Mexicano: the number of matches played, so whoever has played more edges ahead.

Game difference is therefore the most important tiebreaker in most team formats. That is why every game counts, even in a match you have already won or lost.

What is that "ELO"?

The rating you see as a tiebreaker in a ladder is the Slams DSS rating. It is an Elo-style system, tuned specifically for padel and tennis, on a scale from 7.0 to 10.0 (KNLTB style, where lower is better). Winning lowers your rating (you become "better"), losing raises it. Read more in the DSS rating explained.

Buchholz and Sonneborn-Berger

Buchholz and Sonneborn-Berger are tiebreakers from chess, where play uses a Swiss system. Slams uses group and round-robin schedules and does not apply these chess criteria. Instead, game difference, set difference and, in the ladder, the rating determine the order. That keeps the standings recognizable for padel and tennis players.

Want to change something yourself?

The order of the tiebreakers is fixed per format, but you do have influence on the standings. In a league you set the points system. Which columns you show can be adjusted via customizing standings columns, and manual corrections are made via editing the standings manually.
