How to Run a Community Gaming Tournament or League
A community tournament is one of the best things you can do for a gaming group. It gives people a date to show up for, a reason to practise together and something to talk about afterwards. It's also easy to run badly: brackets that stall for an hour because one team vanished, rules that get argued about mid-match, a final that starts at 2 a.m.
This guide covers the decisions that make an event run smoothly: choosing a format, seeding, check-ins, rules, disputes and a timeline you can copy.
Choose a format
The format decides how long the event takes and how many games each team gets. The match counts below are exact, so you can plan the schedule from them.
| Format | How it works | Matches for n teams | Good for |
|---|---|---|---|
| Single elimination | Lose once and you're out | n − 1 (16 teams → 15) | One evening, 8–16 teams |
| Double elimination | Lose twice and you're out; losers drop to a lower bracket | 2n − 2, or 2n − 1 if the grand final is reset (16 teams → 30 or 31) | A full day; fairer, because one bad game doesn't end your run |
| Round robin | Everyone plays everyone once | n(n − 1) ÷ 2 (6 teams → 15) | Small groups, or as a group stage |
| Swiss | Fixed rounds; each round pairs teams with the same record | About log2(n) rounds of n ÷ 2 matches (32 teams → 5 rounds) | Large fields where everyone should keep playing |
| League (season) | Round robin spread over weeks, one match day per week | Same as round robin, spread out | Ongoing community competition |
A reliable choice for most communities is groups, then a bracket: split teams into groups of four, play round robin inside each group (six matches per group, three per team), then send the top two from each group into a single-elimination bracket. Everyone gets at least three games, and the event still finishes in one day.
Work out the schedule before you announce
Estimate how long one match takes in your game, including lobby setup, then add a buffer. A best-of-one in most team shooters or MOBAs takes 30–50 minutes once you include setup; best-of-three finals can take two hours or more. Then count rounds, not matches: in a 16-team single-elimination bracket the eight first-round matches run at the same time, so the event has four rounds.
A 16-team single-elimination evening with 45-minute best-of-one rounds and a best-of-three final is roughly four to five hours. If that's too long, cut the field or play best-of-one throughout. Announce an end time and stick to it, because players remember events that finished when promised.
Seed the bracket fairly
Seeding stops the two strongest teams from meeting in the first round. Options, from simplest to fairest:
- Random: fine for casual events where nobody knows each other's level.
- By rank: average the in-game ranks of each team's players and seed from highest to lowest.
- By past results: for recurring events, seed from the previous tournament or the league table.
In a standard bracket the top seed plays the lowest seed in round one (1 vs 16, 2 vs 15 and so on), so the two best teams can only meet in the final.
Registration and check-in
No-shows are the main cause of stalled brackets, and check-in fixes most of them.
- Registration closes a day or two before the event. Collect the team name, captain, player names and in-game IDs, and each player's rank if you seed by rank.
- Check-in opens 60 minutes before the start and closes 15–30 minutes before. Teams that don't check in are replaced from a waitlist.
- Forfeit time: publish it in advance, for example "10 minutes after your match is called, a team that hasn't joined the lobby forfeits".
Write the rules before anyone asks
Every argument you can have in a tournament has been had before. Answer the common ones in writing, ahead of time:
- Game mode, map pool and how maps are picked (veto order, or the higher seed chooses).
- Who creates the lobby and who reports the score.
- Substitutes: how many each team may register, and whether they can be swapped mid-series.
- Disconnects: whether a match is restarted, paused or played on, and how many times.
- Rank or eligibility limits, if any, and what happens if someone's found to be on a smurf or borrowed account.
- Conduct: your community rules apply, and how admins can penalise or disqualify.
Keep the rules on one page. Long rulebooks don't get read; short ones do.
Handle disputes fast and consistently
Disputes stall brackets. Decide in advance who has the final word (one or two admins who aren't playing), require evidence (a screenshot of the scoreboard, a clip), and set a short window to raise a dispute, such as five minutes after the match. Make the call, write it down, and move on. Consistency matters more than getting every edge case perfect.

Leagues: tournaments that last
A league turns one event into a weekly habit. Run a round robin over several weeks, one match per team per week on a fixed night, keep a standings table, and finish the season with a short playoff for the top four. Leagues are where communities form, because the same people meet every week. Keep seasons short (six to eight weeks) so new teams can join regularly.
Running it on MOT
A tournament needs a place for announcements, a channel for score reports, voice rooms for admins and teams, and a way to find teams to fill the bracket. On MOT you can host all of that in a server, schedule the event, and use finding teammates by game and rank to help solo players form teams before registration closes. Our guide to setting up a community server covers the channel layout.

What's the best tournament format for a small community?
For 8 to 16 teams on a single evening, single elimination is simplest. If you want everyone to play more than one match, use double elimination or groups of four in round robin followed by a short single-elimination bracket.
How many matches does a single-elimination bracket need?
One fewer than the number of teams. Every match eliminates exactly one team and only one team is never eliminated, so 16 teams need 15 matches.
How many matches does a round robin need?
Every pair plays once, so n teams need n × (n − 1) ÷ 2 matches. Six teams need 15 matches; ten teams need 45, which is why round robin works best in small groups.
What is a Swiss format?
Teams play a fixed number of rounds, and each round pairs teams with similar records. Nobody is eliminated early, and you only need about log2(n) rounds to find a clear winner, so 32 teams need roughly five rounds.
How do I handle no-shows?
Run a check-in window that closes 15 to 30 minutes before the start, publish a forfeit time (for example 10 minutes after the scheduled start), and replace teams that miss check-in from a waitlist.
