A conker tournament needs three things: a tree that has dropped its nuts, a shoelace, and someone willing to stand in the middle with a clipboard. Everything else — the bracket, the rosettes, the wooden spoon for the first person out — is decoration. The decoration matters, though, because a well-run competition is the difference between an hour of cheerful chaos and an afternoon people ask you to repeat next year.

Here is the practical side: choosing a format, writing rules people will actually follow, drawing a fair bracket, marshalling matches without a mutiny, and sorting prizes that suit a school field, a pub garden or the corner of a village fete.

Choose a format and a venue that suits it

Knockout is the default and usually the right answer. It is quick, easy to explain and builds tension as the afternoon thins out. Round-robin suits small numbers — eight players or fewer — and guarantees everyone at least a few matches, which matters if you have a field full of children who have been practising for a week. A good compromise for a school is group stages by class, with the winners going into a knockout for the last sixteen.

Do the arithmetic before you promise anything. A single match takes roughly two minutes, so a 32-player knockout is 31 matches. With four lanes playing at once and a marshal on each, that is about 45 minutes of play — plus the unavoidable faff of finding the person who has wandered off to the cake stall. Allow double.

For a venue, find flat ground you can rope off, a table for the bracket, and some shelter. Keep clear of the tombola, the bouncy castle and the queue for the toilets. If you are using a pub garden, ask first and pick a corner away from the tables.

Set the rules before anyone picks up a conker

Print them, read them out and pin them to the table. Nearly every argument at a conker competition comes from two people who have played before with different house rules, so the fix is not a cleverer rule but a clearly stated one. These are the rules most British competitions run on; adjust them if you like, but decide in advance and stay consistent.

  • Fresh conkers only. Horse chestnuts gathered this season, drilled cleanly through the middle. No soaking in vinegar, no baking, no varnish, no glue, no coatings of any kind.
  • Twenty centimetres of string, maximum. Measure the lace from your knuckle to the top of the conker. Any longer and you have an unfair reach.
  • Hold your own lace. Your conker hangs free. You strike at theirs, never at their hand.
  • Alternate strikes. Three misses in a row and you lose the turn. This keeps things moving.
  • Break or drop, and you are out. If your conker shatters, or falls off the string to the ground, you lose the match.
  • Both conkers break on the same strike? Choose now: either replay the match or award it to the striker. Announce which before the first match.
  • Ask "ready?" before every swing. A surprise whack causes more bad feeling than a broken conker.
  • The marshal's word is final. One person rules on tangles, disputed strikes and suspiciously glossy nuts.

Two optional extras are worth considering. Keep a stamp tally: every conker yours destroys counts as a stamp, written on the bracket beside your name, which gives beaten players something to brag about. And let a surviving conker carry its damage into the next round, facing a fresh opponent each time. That is the traditional way, and it produces heroes.

Draw the bracket so it feels fair

Seed last year's winner and runner-up at opposite ends of the draw so they can only meet in the final. Everyone else goes in at random, and pulling names out of a hat in front of an audience is its own small entertainment.

If your entry number is not a neat 8, 16 or 32, you will need byes. Give them to the seeded players or to the youngest entrants, and never to someone who has not turned up yet. Draw the sheet big — A2 on a wall, names in marker — and add a second board for results so passers-by can follow the story. A bracket people can read is a bracket people trust.

Marshalling the day without losing your voice

One marshal per lane, one chief marshal with the board and a pen. Hand each lane a printed copy of the rules and let the chief marshal run the flow.

  1. Call the next two names, send them to a free lane.
  2. Check conkers and strings before the first strike — this is the moment to catch the varnished ringer.
  3. Toss a coin for who strikes first.
  4. Announce every strike: "Ready? Go." Keep it brisk.
  5. Record the result on the board immediately, with the winner's stamp tally.
  6. Send the winner to a holding area near the board. The whole competition stalls when a winner disappears into the crowd.

Keep it safe and sociable

Conkers are heavy enough to sting and a swinging lace can catch an eye, so a few habits are worth insisting on: spectators an arm's length back, no swinging until your opponent is still and looking, nothing at head height, and younger children sitting down so the swings are level. Conkers are not edible and are toxic to dogs and horses, so keep them away from animals and off the picnic blanket. If a child swallows one, speak to a health professional rather than waiting to see what happens.

Prizes and categories that keep everyone playing

A single champion's trophy leaves thirty-one people with nothing to remember. Spread the glory:

  • Champion and runner-up — the serious silverware.
  • First out, with a wooden spoon or a bag of carrots.
  • Most stamps across the whole competition.
  • Best conker name, judged by applause.
  • Youngest competitor, and best-dressed conker if you want a craft table for those waiting.

Small, playful prizes beat cash. A perpetual trophy engraved with each year's winner turns a one-off into a tradition, and a box of rosettes covers everyone who made it past the first round. If you are raising money, a modest entry fee agreed in advance with the venue, plus a donation tin on the table, is plenty — and worth mentioning to whoever handles the fete's accounts.

The week before: a short checklist

  1. Check your trees and gather more conkers than you need. Drill them early, and drill spares.
  2. Buy a bag of shoelaces. Laces snap, and a child with a broken lace is a child in tears.
  3. Print the rules ten times, draw the bracket on A2, and pack clipboards, pens and a whistle.
  4. Confirm the venue, permission, a table and a gazebo, and find out where the nearest first-aid point is.
  5. Line up your marshals — four is a comfortable number — and brief them on the rules the day before.
  6. Collect the trophy, rosettes and spot prizes, and a tin for entry money.
  7. Take a bin bag for broken shells and a spare box of conkers for anyone who arrives empty-handed.

Then all you have to do is stand in the middle, call "ready?", and let the afternoon run itself.
