Round Robin with Playoff

Overview​

A Round Robin with Playoff draw combines group play with subsequent knockout playoff structures. Participants first compete in round robin groups, then advance to playoff brackets based on their finishing positions within their groups.

In the factory, this draw type is represented by the constant ROUND_ROBIN_WITH_PLAYOFF.

Structure​

  • Group stage: A CONTAINER structure holding multiple round robin ITEM groups (identical to a standard ROUND_ROBIN).
  • Playoff structures: One or more single elimination structures that receive participants based on their finishing positions in the group stage.
  • Links: Position-based links connect group finishing positions to playoff draw positions.
Group Stage:
  Group A: P1, P2, P3, P4  -->  1st, 2nd, 3rd, 4th
  Group B: P5, P6, P7, P8  -->  1st, 2nd, 3rd, 4th

Playoff (Gold):   Group winners --> Semifinal bracket
Playoff (Silver): Group 2nd place --> Consolation bracket

Playoff Configuration​

The playoffAttributes parameter controls how many playoff structures are generated and which finishing positions feed into each:

const { drawDefinition } = engine.generateDrawDefinition({
  drawSize: 16,
  drawType: 'ROUND_ROBIN_WITH_PLAYOFF',
  structureOptions: {
    groupSize: 4,
    playoffGroups: [
      { finishingPositions: [1, 2], structureName: 'Gold' },
      { finishingPositions: [3, 4], structureName: 'Silver' },
    ],
  },
});

This creates:

  • 4 round robin groups of 4 participants each.
  • A "Gold" playoff bracket receiving the top 2 from each group (8 participants).
  • A "Silver" playoff bracket receiving positions 3-4 from each group (8 participants).

Use Cases​

  • Tournament formats that combine the fairness of round robin play with the excitement of knockout rounds.
  • World Cup-style formats where group winners and runners-up advance to a bracket.
  • Events that need to determine finishing positions for all participants, not just the winner.
