Doubles tournaments — how it works (with examples)

This page is a visual reference for doubles knockouts on SixBagel. The draw below shows 16 teams (32 fictional players) with pre-filled scores — static only, not connected to the database.

On a live tournament page, official monthly events include Tournament rules & scoring aligned with the bullets below. Any tournament with matches also shows Help: entering scores. Casual events may use different rules; teams, draw slots, and score entry behave the same.

What the example draw shows

Bracket format: Full 16-team outdoor-cap doubles single elimination — same team seeding and R1 slotting as official monthly generation, then illustrative scores.

The round of 16 uses the same intentional mix as the singles demo: set tiebreaks, match tiebreak after a split, pro set, curtailed, walkover with withdrew vs default, normal wins, and one mutual no contest with a following bye in the quarter-final — plus a slightly richer first quarter-final. Later rounds are mostly standard so the draw still produces a winning team. On a live match, all four players must consent for a mutual no contest.

Official monthly knockouts (doubles)

  • Monthly signups are turned into one or more single-elimination team knockouts per event. Each draw needs at least 4 teams; there is no limit on total registrations—extra teams are split into additional draws (separate brackets).
  • Outdoor season: each single draw has at most 16 teams. When 9–15 teams sign up, they are placed in one draw with byes to the top seeds, same as singles. Indoor season: at most 8 teams per draw. Very large signups are split into additional draws.
  • Seeding follows ladder order within the signup list for that pool (not a random draw).
  • Each player registers with a partner using their partner's username (the handle shown on their profile), not a display name nickname.
  • Round deadlines: When the tournament is created, the system assigns a deadline for each knockout round from the competition month (starting at the event). For four-round draws (typical full 16-side brackets), rounds 2–4 each get seven days, and round 1 gets the rest of the time at the start of the month (for example about 10 days in a 31-day month, 9 in a 30-day month, and 7 in a 28-day month). Brackets with any other number of knockout rounds split the month evenly between rounds. You see each round's deadline on the tournament page and on your matches. You get a direct-message reminder two days before your open match's round deadline (once per match). If no score is entered by the deadline, the match is closed as incomplete (both sides withdrawn from that match with a ladder penalty), and the bracket may advance the other side of the pairing.

1. Register with a partner

  • For doubles events you sign up with a partner: enter their username (the handle on their profile), not a display-name nickname. They must confirm in the app (they get a direct message) before your team appears on the roster.
  • When the month-start job runs, teams become one or more single-elimination draws: at least four teams per draw, up to 16 in the outdoor season or eight in the indoor season, with extra teams split into additional brackets.
  • Open your pool from Current tournaments. Each draw has round deadlines (one per knockout round)—see the tournament page and each match on a live event. This example is fully scored, so deadlines are not shown here.

Entering scores

Either player (singles) or either team (doubles) can enter the score for a match, or the host can enter it on behalf of the players. Use the score entry on the match row in your schedule or draw.

  • Mode 1 — full match: enter every set through the end of the match (including a match tiebreak if you played one).
  • Mode 2 — partial match: enter completed sets only, then choose a final outcome (walkover, retired, default, etc.) for unfinished play.
  • Curtailed: use when weather, court time, or mutual agreement stopped the match before a normal completion and you are not using a standard tennis outcome (walkover, retired, default, etc.). Describe what happened in the notes.

If your event uses simple score display, you will only enter set counts (who won each set), not detailed game scores within sets.

Match cards list both names per side, for example:

Alex Chen / Sam Rivera   vs   Jordan Lee / Taylor Kim

2. Scoring examples (same modes as singles)

Choose Mode 1 (two sets + 10-point match tiebreak at 1–1) or Mode 2 (pro set to 8). The tournament default only selects which mode is selected first when you open the form.

Example — team wins in two sets

Set 1:  6 – 2 Set 2:  6 – 4

Curtailed, schedule assistant, and Report issue work the same way as in singles; use notes for curtailed or disputed situations as on the live help text.

3. Curtailed match (teams)

Use the same Curtailed outcome and notes flow as in singles when play stops early by agreement or external limits. Either team or the host can enter the partial score; disagreeing sides should use Report issueScore issue.

Time, place, and conduct

  • Agree on date, time, and court with your opponent using chat or your own contact method.
  • Arrive on time and ready to play.
  • Bring balls and any shared equipment you agreed on.
  • Follow fair play, host or facility rules, and any code of conduct for the event.

Match outcomes (walkover, default, retired, etc.)

  • Walkover: one side does not play — for example, the opponent does not show, is injured before play begins, or withdraws before any meaningful play. The other side is credited with the win without playing a full match.
  • Withdrew before match: a player or team pulls out before the scheduled start so no contest takes place; the opponent is advanced.
  • Default during match: a player or team is unable to continue because of injury, illness, equipment failure, or rule violations after play has started. The opponent wins the match according to the score entered and the default reason you select.
  • Disqualification: a player or team is removed for serious misconduct or rule breaches. The opponent wins; use notes to summarize what happened for the host.
  • Retired: a player or team stops play after it has started because of injury, illness, cramping, or similar. The opponent wins; record completed sets and choose Retired as the final outcome.
  • Curtailed: play stops early by agreement or external constraint (for example, weather or court booking limits) without a walkover, default, or retirement. Record completed sets and explain the situation in the notes.
  • Mutual no contest: both sides agree not to play the scheduled match — for example, they cannot find a workable time before the deadline. In singles, both players must confirm. In doubles, all four players must confirm. The draw records a mutual no contest instead of a forfeit to one side.

Disputes and no-shows

  • If you disagree about a score or outcome, use Report issue on the match and choose Score issue so a host can review chat and ladder history.
  • If your opponent is more than 15 minutes late without a clear message, you may claim a walkover after trying to contact them. The same idea applies if you reached out to schedule or confirm play but they never replied in good time and the round deadline passed — describe your outreach in the report.
  • Hosts may adjust results that clearly conflict with posted evidence or repeated unfair behavior.

4. Schedule assistant

Schedule assistant on a match card lets each side save availability; the page suggests overlapping times. Agree court location off-app.

5. How the draw advances (teams)

Knockout advancement matches singles, but each slot is a team (two players). A match is resolved when there is a winner on the card, a staff-recorded forfeit or walkover, a mutual no contest, or an automatic incomplete closure — not only when someone wins in straight sets.

  • Completed match. Enter set scores; the winning team advances to the next round. The diagram connects that team into the slot fed by their first-round match.
  • Withdrawal from the tournament (locked draw). Leaving drops the whole team from the event; open matches are forfeited, opponents advance, and ladder rules may apply. This is not the same as mutually voiding one match.
  • No-show or dispute. Use Report issue on the match (Score issue for score problems) — including when you reached out to schedule but the other side never replied in good time before the round deadline. Staff may record walkover or default as appropriate. Cards may show withdrawal-style labels when there is no normal set line.
  • Mutual no contest. When both teams agree they cannot play this match for an allowed reason, all four players consent in-app; the match ends with no winner and no ladder points from that pairing. The other feeder in that part of the draw may advance against a BYE. The example below shows one void and that bye.
  • Incomplete (deadline). For official single-elimination months, if no score is entered by the deadline, the match is Incomplete: both sides withdrawn from that match with a ladder penalty, and the draw may award a bye on the other side (see official monthly doubles rules above).

Your team's next match appears when the path that feeds your slot is resolved — you do not need every other match in the event to finish first.

Ladder rewards on real events

The knockout and champion ladder bonuses below apply to draw tournaments only, not to casual pickup games. Pickup matches can still earn per-match ladder points when the host enabled ladder tracking for that game. Points are added when scores are saved (and when a knockout champion is decided for tournaments). Totals appear on the Rankings page and in the user guide. Singles and doubles use separate totals. Outdoor (May through October) and indoor (November through April) ladders: each rolls over 12 calendar months within its own months only. There is no mixing between seasons. Points from a match count only toward the ladder for that event's format.

  • Knockout round wins (main draw): each time a main-draw knockout slot records a win that qualifies (not a bye slot, not the consolation draw), you get an extra ladder bonus on top of the match formula — a flat 2 ladder points in every round. Doubles partners each get the full amount. You also earn tournament coins for the same wins: max(1, round × 1) (e.g. round 1 = 1, round 3 = 3).
  • Tournament winner (single elimination): a large extra ladder bonus when the final has a decided score, plus a champion title on your profile — in addition to the knockout win bonuses above. The amount follows registered entrant count (players in singles, teams in doubles — not the padded bracket slot count when byes fill out a power-of-two draw):
    • +10 — 16+ entrants (e.g. full 16-player singles draw)
    • +6 — 8–15 entrants (e.g. 12-player draw padded to 16 slots)
    • +4 — 4–7 entrants
    • +3 — 1–3 entrants

    Champion tournament coins (same entrant-count tiers; a modest slice — most coins are from signup and from playing matches): +12 / +9 / +6 / +4 — per player when the final is decided (doubles partners each get the full amount).

  • Each completed main-draw match: no flat participation points. The winner earns an Elo-scaled win bonus; the loser takes a scaled loss adjustment (symmetric Elo: default K = 25; K = 40 on your first 5 match-result changes per format if your account was created on or after 5/1/2026 (UTC)). If you win without playing (bye, walkover over a withdrawal or no-show, etc.), you do not receive those match win points — you still receive knockout round advancement bonuses when this match qualifies. Exact amounts depend on ratings when the match was played.

Showing up and playing: +8 tournament coins once per first signup, plus +2 per main-draw match you play (both sides, win or loss). Signup credit is revoked if you leave in ways that remove the award, same as before.

How play starts: sign up on the Monthly registration page before the end of the month. On the 1st, the system ranks players by ladder points (your profile self-rating breaks ties when points are close) and builds skill-based groups — top 16 in skill group 1, the next players in skill group 2, and so on. Overflow players are placed in additional single-elimination pools. The next-round match appears as soon as both feeder matches are decided — you don't have to wait for the whole round to finish. Round deadlines don't block earlier rounds from moving; the daily job reminds players two days before each deadline and auto-closes unscored knockout matches after the deadline (Incomplete, ladder penalty, bye for the sibling path).

About the example draw below

Framed from Alex Chen’s perspective on the champion team: the list below the diagram only shows matches where he played. The diagram is the full 16-team draw. Same layout as live doubles. This mirrors a full outdoor-season team bracket (up to 16 teams, four knockout rounds). Official draws get a deadline per round, spread through the month, with a DM reminder two days before each deadline—see a live tournament for dates on each match. The round of 16 uses the same mix as the singles example (Mode 1 with set TB, split + match tiebreak, pro set, curtailed, walkover vs withdrew vs default, straight wins, plus one mutual no contest and the resulting bye in the quarter-final). The first quarter-final shows 7–6 with set TB and 6–4. Later rounds are mostly standard wins so the draw reaches a champion.
