How to Organise a Conker Tournament: Rules and Bracket Guide

A pub garden, a box of conkers, and somebody's shoelace. That is how most tournaments begin. Then eight people are standing around asking who plays whom, and the afternoon quietly dissolves into argument. Twenty minutes of planning beforehand removes almost all of it. Here is how to run a conker competition that feels fair, moves quickly, and produces a winner nobody disputes.

Choose the Format Before You Choose a Date

The format decides everything else: how many matches you are committing to, how long the day runs, and whether the best player actually ends up winning. Three options cover nearly every local event.

• Single elimination. Lose once and you are out. Best for 8, 16 or 32 players, because the maths is clean and the tension builds nicely through the rounds. It is also the harshest format: one unlucky bounce in round one ends your afternoon.
• Round robin. Everyone plays everyone. Ideal for six to ten players, and for a club that meets regularly, since the title goes to whoever won most matches rather than to whoever dodged a bad draw. Ten players means 45 matches, so keep the entry list small.
• Groups, then knockout. Groups of four, top two through to a bracket. This is the sweet spot for 12 to 24 players: everybody gets at least three matches, and the final rounds still feel like a proper event.

Write the number of rounds on the board before anyone arrives. Sixteen players in single elimination means four rounds and 15 matches. Knowing that number stops the mid-afternoon panic about whether there is time to finish.

Agree the Rules and Pin Them Up

Every conker argument you have ever heard comes from a rule nobody said out loud. Settle these three areas in advance and print them, or chalk them on a board where players can point at them.

How a match is played

Two players, one conker each, each conker threaded on a lace with a knot at the bottom. One player holds their conker out at a sensible height and keeps it still; the other swings. One strike per turn, then the roles swap. The player whose conker stays intact wins. Agree a maximum lace length too, ideally measured against a marked stick or a template lace kept behind the desk, so nobody turns up with a metre of paracord and a physics advantage.

What counts as a foul

• Touching the opposing conker with your hand or fingers.
• Wrapping the lace around your fingers to stop the conker swinging freely, or pulling it away as the strike comes in.
• Aiming at the lace, the hand or the wrist instead of the conker.
• Striking with anything other than the conker itself, or more than once in a turn.
• Stamping on a fallen conker, or swapping your conker mid-match.

Keep the list short and readable. A rule nobody can remember will not be enforced, and an unenforced rule causes more bad feeling than no rule at all.

Scoring, and what happens when a conker breaks

Traditional scoring is a ladder. A fresh conker is a none-er. Beat a none-er and yours becomes a one-er. Beat a two-er with your one-er and yours becomes a four-er: your score, plus theirs, plus one. Variants exist, so state your version in writing before the first match and stick to it for the whole day.

Decide in advance whether players keep the same conker throughout the tournament or start each round with a fresh one. Keeping the same conker all day is the more traditional and more dramatic choice, because damage carries over, but it does mean the draw matters more. If a conker breaks, the owner of the broken conker loses, even if it shattered on their own swing. That single sentence resolves most disputes.

Equipment: A Short, Boring List

1. A conker for each entrant, plus a few spares held by the marshal.
2. Laces or strong string, cut to the agreed length, one per player.
3. A drill with a 4–5mm bit, or a skewer and patience, for the holes.
4. A whiteboard or a large sheet of paper for the bracket, plus marker pens.
5. A whistle or bell, a watch, and a score sheet.
6. A basic first aid kit, and somewhere for younger players to sit between matches.

Set up one table as a check-in point. Every conker goes through it before the draw: hole drilled, knot secure, lace the right length. It takes two minutes per player and it means nobody spends the whole tournament arguing about someone else's knot.

Preparing the Conkers Without Cheating

Hardening methods are the oldest argument in the game. Vinegar, baking, freezing, and leaving them in a shed for a year all have their devotees. Pick one position and state it clearly: natural ageing is fine, anything that changes the material is not. That rules out varnish, glue, resin, chemical soaks, and drilled-out centres stuffed with filler. Softness and weight can be checked by hand at check-in, and a conker that fails inspection is simply swapped for a spare.

Set a cut-off too. Say that conkers must be collected before the event and brought whole, so nobody turns up with something that has been drying on a radiator since August. If you want a gentle nod to the season, keep the collection date on the poster and let people brag about it.

Drawing and Running the Bracket

1. Register. Names on the sheet, in order of arrival.
2. Seed lightly. If you have a defending champion or an obvious favourite, give them the top line. Everybody else goes into a hat.
3. Draw in pairs and fill the bracket from top to bottom. If the numbers do not divide neatly, give the byes to the top seeds.
4. Call matches in waves. Two or three at a time, four at most. Everybody else watches, which is half the pleasure of the day.
5. Record each result immediately on the board, with the winning conker's new score beside the name.
6. Consolation plate. Anyone knocked out in round one can enter a second, shorter bracket. It keeps children and newcomers involved until the end.

A single match usually takes two to five minutes. A 16-player bracket is roughly an hour of play, so allow two hours including check-in, breaks and the inevitable faffing. Publish the start time of each round on the board and hold to it.

Marshals, Fair Play and the Safety Basics

Appoint one marshal per playing area, ideally someone not related to anyone still in the competition. A marshal calls the turn, watches for fouls, and has the final word on disputes. If two players cannot agree and the rules do not cover the situation, replay the point. Never replay a whole match unless the error was the marshal's.

Keep spectators a metre or two back and keep the stationary conker below waist height. A conker on a swinging lace is a real hazard to eyes, particularly with younger players, so supervise children closely and consider eye protection for the youngest entrants. Give everyone room to swing, and stop a match if anyone wanders into range.

After the Final: Keep the Record

Photograph the bracket before you wipe it, note the champion conker's score, and write the winner's name somewhere that will survive the year. Store the winning conker in a labelled tin or matchbox, because next autumn somebody will want to defend the title with it.

Then leave the rules sheet, the bracket template and the measuring stick in the same box as the spare laces. Next year you will not be starting from scratch, and the tournament will take a quarter of the effort to run twice as well.
