Structures available on Toornament

Updated 4 months ago ​by Geoffroy "Vomact" Piot

As Toornament offers a vast array of competition structures, here’s a quick and useful guide on what each of them do best. Must read, if you need to pick the format that suits you best!

Single Elimination

Format Details
  • Pitch: The most used format, where the winner of each match advances forward and meets another winner,until one final victor remains.

  • Duration: Moderate. Each round is 50% shorter than the previous one.

  • Capacity: Can accommodate a wide range of participants.

  • Level: Beginner.

  • Pros: easy to handle and understand, straightforward.

  • Cons: no room for error, weaker participants will only play one single match.

  • Pick Bracket if: you want to rely on a quick, solid format known by everybody. Perfect for a first competition.

Double Elimination

Format Details
  • Pitch: The Double Bracket adds a "Loser Bracket" welcoming all the participants who lost a match. You then have to lose twice to be eliminated.

  • Duration: Average. Be aware that this format more than doubles the time needed for a tournament compared to the Single Elimination.

  • Capacity: Can accommodate a wide range of participants, but the Loser Bracket can get loaded at times.

  • Level: Intermediate.

  • Pros: Greater match variety, possibility for comebacks.

  • Cons: Hard to understand, leads to confusing situation due to variants (like the Double Grand Finals), timing issues between the two brackets.

  • Pick Double Bracket if: you want to provide a flexible experience for all your participants, where a single lose doesn't mean elimination.


Format Details
  • Pitch: Dispatches the participants into smaller pools where they will face the other members of their group.

  • Capacity: Limited. Groups are designed to keep a relatively low number of participants, but you can spawn numerous groups.

  • Duration : Depends on the group size, but generally quite short.

  • Level: Beginner.

  • Pros: Easy to understand and to set up, good to separate seeds, flexibility as each group is independent from the others.

  • Cons: Doesn’t work well as a standalone structure, better when followed by an Elimination-type structure.

  • Pick Groups if: you have numerous participants from different skill levels and you want to have several matches played simultaneously.

Bracket Groups

Format Details
  • Pitch: Each group is a bracket. Widely used by the GSL (4 participants in a Double Bracket), giving the name "GSL Groups".

  • Capacity: Usually small, but tournaments like the Vainglory League and March Madness use 64 participants Bracket Groups.

  • Duration: A bit shorter than regular groups, as there is no need for participants to face all their opponents to determine who's qualified.

  • Level: Advanced.

  • Pros: All matches are important, no participant has won or lost until he has played all his matches.

  • Cons: Weaker participants play very few matches, harder to understand than the regular Groups.

  • Pick Bracket Group if: the average participants’ skill level is consistent. Great for high level tournaments.


Format Details
  • Pitch: Same as the Round-Robin. Usually a Standalone stage, the participant with the most points at the end wins.

  • Capacity: Accommodates with any number of participants, but better for small to medium size.

  • Duration: Long, as each participant plays all his opponents. Some leagues even use Double-Robin format.

  • Level: Beginner. The League format is straightforward. Its main difficulty lies in the workload involved and its points system.

  • Pro: flexible schedule, lots of matches for everybody, rewards the most consistent performing participant.

  • Cons: Stretches over a long duration and can become boring for the weaker participants who already know they can’t win.

  • Pick League if: you want to create a continuous stream of matches for all your participants. Works well for online competitions.

Swiss System

Format Details
  • Pitch: The System pairs participants with equal or close level, based on their previous results, getting more and more accurate as rounds go by.

  • Duration: Variable, but not exponentially long like a League, as you can choose the number of rounds.

  • Capacity: Works well with any number of participants.

  • Level: Advanced. The pairing and tiebreaking algorithm are somewhat complicated, but Toornament handles everything on its own!

  • Pros: Most match-ups are well balanced for everyone.

  • Cons: Abandons are possible, but not that impactful, as dropped-out participants are simply not paired anymore.

  • Pick Swiss System if: you want to entertain participants with various skill level. Only the first rounds can be random.


  • Pitch: All the structures explained above can be combined freely: Groups to Bracket, League to Playoffs, Groups to Groups to Bracket etc.

  • Duration: A little bit tricky but keep this in mind: a complex structure takes more time than the addition of its two sub-structures.

  • Capacity: Depends on the combination.

  • Level: Intermediate, Advanced.

  • Pros: More variety in match ups and match values, can suit any situation, with qualifying or seeding rounds into Elimination.

  • Cons: There are no real con except the added workload.

  • Pick a combination of formats if: you want to offer an exhaustive experience to your participants and your audience.
