Tournament Guide
How to run an RPS tournament that people actually remember.
Tournament Formats
Single Elimination
The classic. You lose, you're out, you go home, you think about what you did. Fast, dramatic, and easy to run. Best for 8-64 players and casual events.
- Pros: Simple, fast, the finals feel like they matter
- Cons: One bad throw can end everything you've worked for
- Time: About 30 minutes for 32 players
Double Elimination
Lose once and you drop to the losers' bracket. Lose again and now you're actually out. This gives everyone at least two matches and rewards consistency over single-round luck.
- Pros: Fairer, more games per player, redemption arcs
- Cons: Takes roughly twice as long
- Time: About 60 minutes for 32 players
Round Robin
Everyone plays everyone. Points are tallied. Top scorer wins. Best for small groups of 6-12 players where you want maximum interaction and nobody wants to sit out. Very democratic. Very time-consuming.
Swiss System
Players are paired against opponents with similar records each round. After 4-6 rounds, the best record wins. Nobody gets eliminated. Efficient for large groups. Invented by the Swiss, who are good at being fair.
Planning Checklist
| Item | Details |
|---|---|
| Players | Minimum 8. Powers of 2 work best (8, 16, 32, 64). If you have 9, convince someone to leave. |
| Space | One "arena" per simultaneous match. About 6 feet per pair. Less space than a ping-pong table. |
| Time | Allow 2 minutes per match. 32-person single elim takes about 30 minutes. |
| Referee(s) | One per match in semifinals and beyond. Optional for early rounds but recommended. |
| Bracket board | Whiteboard, poster, or digital display. People need to see the bracket. It builds the drama. |
| Prizes | Optional but effective. Trophy, gift card, or just the undying respect of everyone present. |
| Rules printout | Print or display the official rules. Prevents arguments. |

Tournament operations checklist
Use this as a minimum control list and add venue, safeguarding, legal, insurance, broadcast, and sponsor requirements that apply to your event.
Before registration opens
- Choose the format, eligibility rules, capacity, venue, date, and cancellation policy.
- Publish the official throw cadence, match format, dispute process, and accessibility contact.
- Name the event owner, head referee, scorekeeper, safety contact, and backup for each role.
- Confirm prize terms, sponsor approvals, photo/video consent, and privacy notices in writing.
Before doors open
- Freeze the player list, seeds, byes, court assignments, and a versioned bracket copy.
- Brief referees with the same rules sheet and test the timer, display, network, and result workflow.
- Mark check-in, warm-up, spectator, media, and accessible routes at the venue.
- Prepare an offline bracket/result fallback and a visible correction log.
During and after the event
- Record every accepted result with player identities, round, court, referee, and timestamp.
- Resolve protests before advancing the affected bracket branch; preserve the decision note.
- Publish only reconciled final results and clearly label provisional totals or delayed verification.
- Retain consent-safe evidence, issue corrections visibly, and record the archive owner and review date.
Building the Bracket
- Register players. Get a final headcount before building anything. Do not wing this.
- Seed or randomize. Random seeding for casual events. Ranked seeding for competitive events so the best don't meet in Round 1.
- Handle byes. Not a perfect power of 2? Give byes (automatic advancement) to top seeds in round 1. Math requires this.
- Display the bracket. A visible bracket builds excitement like nothing else. Use a whiteboard, projected screen, or online tool.
Rules and Judging
Before the first match, announce these rules to everyone. Loudly. Clearly. No ambiguity.
- Counting method: "Rock... Paper... Scissors... Shoot!" Throws revealed on "Shoot." Not before. Not after.
- Match format: Best of 3 for early rounds, best of 5 for semifinals and finals. More rounds means fewer upsets.
- Legal throws: Rock (fist), Paper (flat hand), Scissors (two fingers). Anything else is a foul. No, "dynamite" is not a throw.
- Timing: Both players must throw simultaneously. Late throws are a foul. If you can see their throw before you make yours, you're cheating.
- Disputes: Referee's call is final. No replays unless both players agree the count was off.
For the complete competitive ruleset, see the Official WRPSA Rules.
Running the Event
Before the Event
- Prepare and display the bracket
- Brief referees on rules and dispute resolution
- Set up a staging area where next-up players wait and nervously think about their throws
During Matches
- Call pairs to the arena. Confirm both players are ready.
- Referee counts or the players self-count (announce which method you're using beforehand)
- Record results immediately on the bracket. People will check.
- Keep energy high. Announce winners. Encourage cheering. This is a spectator sport whether you planned for it or not.
Finals
- Switch to best-of-5 for maximum drama
- Clear the main area so everyone can watch. This is the main event.
- Consider having a commentator or MC. It sounds ridiculous. It makes everything better.
- Take photos and video. The champion will want proof.
