🔁 Format Variations
Two recommended formats based on tournament size:
🟩 Format A – Compact Champions League (18 to ~24 Teams)
✅ Progression Logic
| Rank | Action |
|---|---|
| 1st–4th | Advance directly to Quarter-finals |
| 5th–12th | Enter Playoffs (Bo3 series) |
| 13th–18th+ | Eliminated |
✅ Recommended Team Sizes
| Teams | Advancing | Eliminated | Notes |
|---|---|---|---|
| 18 | 12 | 6 | ✅ Ideal structure |
| 20 | 12 | 8 | ✅ Balanced |
| 22 | 12 | 10 | ⚠️ Higher elimination pressure |
| 24 | 12 | 12 | ⚠️ 50% elimination threshold |
🧮 Match Count (Example: 18 Teams)
| Phase | Series | Avg. Matches (Bo3) |
|---|---|---|
| League Phase | 72 matches | 72 |
| Playoffs (4 Bo3) | 4 series | ~8 (min 8, max 12) |
| Quarter-finals (4 Bo3) | 4 series | ~8 |
| Semi-finals (2 Bo3) | 2 series | ~4 |
| Final (1 match) | 1 | 1 |
| Total | — | ~93 to 103 matches |
🎯 Bo3 series average 2.25 matches per tie. Total match count varies by actual series outcomes.
🟦 Format B – Expanded Champions League (26 to 36 Teams)
✅ Progression Logic
| Rank | Action |
|---|---|
| 1st–8th | Advance directly to Round of 16 |
| 9th–24th | Enter Playoffs (Bo3 series) |
| 25th–32nd+ | Eliminated |
✅ Recommended Team Sizes
| Teams | Advancing | Eliminated | Notes |
|---|---|---|---|
| 26 | 24 | 2 | ❌ Too forgiving |
| 28 | 24 | 4 | ⚠️ Low pressure |
| 32 | 24 | 8 | ✅ Well-balanced |
| 36 | 24 | 12 | ✅ Strong stakes and structure |
🧮 Match Count (Example: 32 Teams)
| Phase | Series | Avg. Matches (Bo3) |
|---|---|---|
| League Phase | 128 matches | 128 |
| Playoffs (8 Bo3) | 8 series | ~18 (min 16, max 24) |
| Round of 16 (8 Bo3) | 8 series | ~18 |
| Quarter-finals (4 Bo3) | 4 series | ~9 |
| Semi-finals (2 Bo3) | 2 series | ~4.5 |
| Final (1 match) | 1 | 1 |
| Total | — | ~178 to 204 matches |
🎯 Format Selection Strategy
| Total Teams | Recommended Format | Why |
|---|---|---|
| 18–24 | 4 Direct + 8 Playoffs → Quarter-finals | Balanced and fast-paced |
| 26–36 | 8 Direct + 16 Playoffs → Round of 16 | Scales well, keeps high competitiveness |
| > 36 | Consider dual-league or regionalized groups | Single group becomes unmanageable |
✅ Design Recommendations
- Ensure unique matchups in the league phase.
- Track match history to prevent rematches.
- Bo3 logic must support:
- Match 1
- Match 2
- Match 3 (if necessary)
- Final rankings should use tiebreakers: Head-to-head, goal difference, goals scored.
📌 Implementation Notes
- Store Bo3 series as grouped match containers (e.g.,
series_id,team1,team2, results). - Allow admin override for rescheduling, score adjustments, or match resolution.
- Consider expanding to home/away in Bo3 for local/online formats.
