Generating fixtures

How to generate match schedules for your tournament

Before generating fixtures, make sure all teams have enrolled in the tournament. Generating fixtures creates the full match schedule — existing fixtures are deleted and recreated each time.

When to generate

Fixtures can be generated once at least two teams are enrolled. Generating again at any point will erase the current schedule and all recorded results, resetting classifications back to zero.

Regenerating fixtures deletes all existing matches, recorded scores, and resets the standings. Player statistics are also reset to zero.

Generation modes

There are two modes available for every tournament type:

• Random — teams are shuffled and assigned to matches at random.
• Custom (seeded) — you assign a skill level (Nivel 1–4) to each team before generating. Level 1 is the strongest.

With the custom mode, if all teams are assigned the same level the system falls back to random generation automatically.

Use custom generation when you want competitive balance — the algorithm ensures top seeds avoid each other in early rounds and difficult matchups are scheduled in the middle of the season.

Generation workflow

1. Open the fixtures page

   Navigate to your tournament and go to the matches section. If no fixtures exist yet, you will see the option to generate them.

2. Choose a generation mode

   Select Random to generate immediately, or Custom to assign skill levels first.

   • Random: POST /torneo/<id>/enfrentamientos/generar_aleatorios/
   • Custom: GET/POST /torneo/<id>/enfrentamientos/generar_pers/
3. Assign skill levels (custom only)

   For each enrolled team, select a level from Nivel 1 (best) to Nivel 4 (weakest). Submit the form to generate.

4. Review the generated schedule

   You are redirected to round/matchday 1 of the new schedule. Use the round selector to browse all matchdays or rounds.

Tournament type details

Liga (League)

A full round-robin schedule is generated using all enrolled teams. Every team plays every other team exactly once (or twice with home-and-away legs).

Home and away (ida y vuelta)

When the ida/vuelta option is enabled, a second set of matchdays is appended where local and away sides are swapped. The total number of matchdays doubles.

Reordering algorithm (custom mode)

When teams have different skill levels assigned, the matchday order is reordered so that:

• Easy matchdays (low-level teams facing each other) appear at the start and end of the season.
• Hard matchdays (top-level clashes) are placed in the middle of the season.

This algorithm only activates when there are 4 or more matchdays and at least two different skill levels are present.

Skill level weights used for reordering:

Matchup	Weight
Level 1 vs Level 1	3 (hardest)
Level 1 or 2 vs Level 1 or 2	2
Level 1 or 2 vs Level 3	1
All other combinations	0 (easiest)

Eliminatoria (Knockout)

A single-elimination bracket is generated. Teams are placed in the bracket starting from the earliest round (e.g. Round of 16, Quarterfinals, Semifinals, Final) based on how many teams are enrolled.

Available rounds:

Code	Round
16AV	Round of 16 (Dieciseisavos)
8AV	Round of 8 (Octavos)
CUA	Quarterfinals
SEM	Semifinals
FIN	Final

Seeded bracket (custom mode)

Teams are sorted by skill level before being placed in the bracket. The top seeds (Level 1) are placed on opposite sides of the draw so they can only meet in the Final. This prevents the strongest teams from eliminating each other in early rounds.

If the number of teams is not a power of 2, some top-seeded teams receive a bye and advance directly to the next round.

Eliminatoria con Fase de Grupos (Group Stage + Knockout)

Teams are distributed across groups (A, B, C, …) and play a round-robin within their group. After all group matches are completed, the top N teams from each group advance to a knockout bracket.

Group distribution (custom mode)

Teams are sorted by skill level and distributed across groups in a snake/round-robin pattern so that each group has a balanced mix of skill levels.

Home and away (ida y vuelta)

The same ida/vuelta option available for Liga applies to the group stage matchdays.

Knockout phase

Once all group stage matches are recorded and the group phase is complete, the knockout bracket is generated automatically. The number of teams advancing is configured by the n_clasificados_grupo setting on the tournament.
