Classroom Chess Tournament: a Swiss event in 45 minutes

Alexey Mudry · updated August 25, 2026
A tournament inside one class is a great way to fill a homeroom period or after-school time usefully. There is one constraint: time is short, usually a single 45-minute lesson. So everything must move fast - and here the bot is indispensable: while the kids take their seats, the pairing is already done. Let's see how to fit a full tournament into one lesson.

Format: only fast blitz

In 45 minutes you can play 3-4 rounds of blitz 5+0 or even 3+2. For a class of 25-30 that's too few for a full winner, so there are two approaches: run a short 3-4 round tournament and award the leaders, or stretch it over several homeroom periods, 3-4 rounds each.

If you play without clocks at all, you can skip timing - just cap the game by "until the bell". A chess clock without installing anything opens from a link during the break - no app to put on a dozen phones. But with a clock on a phone the tournament runs livelier and fits the lesson more precisely.

How to fit the lesson

The trick to speed is preparing in advance. At home, create the tournament in the bot Vibe Chess Bot with /create_tournament and enter the whole class as guests by name. Then in the lesson you just press /start_tournament - pairings and tables appear instantly.

Results are entered by the teacher or by appointed pupil "arbiters" - which also involves those not playing that round. Between rounds, /next_round, and a fresh pairing is ready in seconds.

Why it beats 'play whoever you want'

Free pairings at recess leave weaker players without games, while the strong beat everyone quickly and get bored. The Swiss system in the bot fixes both: everyone plays the same number of games, and from round two opponents are matched by strength. The result is a fair, exciting tournament with a clear winner - in the same lesson time.

Fill a homeroom period with a chess tournament

Prepare the tournament in the bot beforehand, enter the class as guests - and in the lesson just press one button. Pairings and the table appear themselves.

Frequently asked questions

Is it realistic to run a tournament in one lesson?

Yes, if you prepare it beforehand: enter the class into the bot at home and just start it in the lesson. In 45 minutes you get 3-4 rounds of blitz - enough for a short tournament with the leaders awarded.

Do the kids need phones?

No. The teacher's phone is enough: the whole class is entered as guests by name, and results are entered by the teacher or pupil-arbiters.

What if the class is large - 30 kids?

Either run a short 3-4 round tournament and award the leaders, or stretch it over several homeroom periods. The bot keeps the pairing correct at any size.

How do I keep those not playing busy?

Appoint them as helper-arbiters: they watch games and enter results. That involves the whole class, not just those at the boards.

Do I need chess clocks?

Not necessarily. You can play without clocks, capping a game by the bell. But a free phone clock makes the blitz more dynamic and helps fit the lesson.

The tournament app

How to run a tournament without being an arbiter

No arbiter skills required. The app takes over the part that usually stops people from running tournaments at all: who plays whom in each round and who finishes first.

Swiss system

works for ten players and for fifty

Round robin

for a small group that wants to play everyone

Free meetup

for those who do not need a bracket at all

How the tournament runs
  1. 1Creating the event takes a minute

  3. 3Pairings follow FIDE rules (Dutch system, the bbpPairings engine)
  4. 4Results go in with two taps and the table recalculates instantly

More than a bot: the app, FIDE rules and a TRF report

  • The app. Besides the bot there is an app - inside Telegram and simply at vibechess.ru/app: what is on in your city, the player list, a live table, the current round, your profile and game history - everything that is awkward to read as chat messages.
  • Pairings by FIDE rules. Pairings are computed by bbpPairings, an open-source engine implementing the Dutch system: score groups, floats on an odd field, colour alternation, no rematches and no two byes in a row.
  • A TRF report. A finished tournament exports as a single file in the FIDE data exchange format - the one arbiter software and federations accept. Your profile stores the FIDE ID, national federation code, title, sex and date of birth for it.
  • Free. All of the above, with no subscriptions, paid plans or limits on the number of tournaments and players.

Full overview

Missing a feature? Message the developers

The bot is constantly improved based on real tournaments. If you need a feature that isn't there yet, message the developers right inside the bot with the /support command. Many features appeared exactly because organizers asked for them, and useful ideas get added quickly.
