The rules behind the results.
Choose the rules before playing
The default is three points for a win, one for a draw and zero for a loss. Change those values when creating the league if your competition uses another system. Published competition rules should decide the scoring system, not a convenient default.
Understand score difference
Score difference is total scores for minus scores against. A team that scores 12 and concedes 8 has a difference of +4. This is different from a ratio or head-to-head record, neither of which is silently substituted here.
When competitors are still tied
Rank first by points, then by your selected difference, scores-for or wins measure. Competitors still equal share a rank; alphabetical display does not award a higher finishing position. If your event needs a sole winner, decide a playoff or other published rule outside this first version.
An example points calculation
Two wins and a draw earn seven points under the default system: 2 × 3 + 1 × 1 = 7. An unplayed fixture earns no points. Updating or clearing a recorded result recalculates the table from the remaining recorded matches.
Compare match counts before choosing your format
For n entrants, a knockout needs n − 1 played matches to find a champion. A single round robin needs n × (n − 1) ÷ 2 matches; home and away doubles that figure. A third-place playoff adds one match to a knockout.
| Entrants | Knockout | Single round robin | Home and away |
|---|---|---|---|
| 4 | 3 | 6 | 12 |
| 6 | 5 | 15 | 30 |
| 8 | 7 | 28 | 56 |
| 12 | 11 | 66 | 132 |
| 16 | 15 | 120 | 240 |
Eight teams need seven knockout matches or 28 single round-robin fixtures. Choose knockout for a shorter event; choose round robin when playing every opponent matters. Court availability, rest periods and dependent rounds still affect the schedule.
