Rock Paper Scissors Referee Guide
A good referee makes the game feel fair. A bad one makes every round feel negotiable.
The Job
A referee exists to make the match clear, fair, and fast. That means controlling cadence, watching for fouls, resolving ambiguity, and preventing the room from turning into a debate club after every close throw.
You are not there to be theatrical. You are there to be trusted. If you need the event-level logistics, read the Tournament Guide. If you need the conduct expectations for players and spectators, read Tournament Etiquette. This page is about officiating the match itself.
Before the Match Starts
- Confirm the players. Make sure the right two people are in front of you.
- Confirm the format. Best-of-3, best-of-5, replay policy, and any event-specific instructions should be settled before the first count.
- Check visibility. You need a clear line of sight to both hands. If you cannot see the throw, you cannot sell the call.
- Set expectations. Explain the cadence, remind players to throw on time, and make it clear that your call controls the round.
Control the Cadence
Cadence is the backbone of fair officiating. The count must be consistent enough that neither player can game it and clear enough that both know exactly when the reveal should happen.
- Use the same rhythm every round. Inconsistent tempo creates preventable arguments.
- Project clearly. If the room cannot hear you, the room will invent its own timing.
- Do not let players drag the count around. Your rhythm should control the throw, not their nerves.

What You Are Watching For
| Issue | What it looks like | Typical response |
|---|---|---|
| False start | Hand opens early before the final reveal beat | Warning or replay depending on event policy |
| Late throw | Player appears to react after seeing the opponent | Immediate round loss in serious play |
| Illegal throw | Ambiguous hand shape or non-standard gesture | Round loss or replay if the room policy allows it |
| Obstruction | Hand hidden from opponent or official view | Reset the round and warn the player |
| Conduct problem | Stalling, arguing, crowd baiting, intimidation | Warning, then escalation if repeated |
Make the Call Like You Mean It
Weak calls create more conflict than tough calls. If you saw it clearly, say it clearly. Name the winning throw, indicate the player, and move the match forward. Hesitation tells the room your authority is optional. It is not.
If you genuinely did not have a clean angle, do not bluff confidence. Reset the round. The goal is credibility, not ego.

Handle Disputes Without Feeding Them
- Listen briefly. Players should be heard, but not indulged forever.
- Restate the call once. Calmly, directly, without starting a speech.
- Separate judgment from emotion. A loud player is not automatically a right player.
- Escalate when needed. If the event has a head official, know when to involve them and when not to.

What Makes a Great Referee
The best referees are not the loudest or the most authoritarian. They are the ones players stop thinking about because the match feels clean. They are consistent under pressure, not eager for attention, and difficult to rattle.
- They keep the match moving.
- They protect fairness without performing outrage.
- They apply the same standard to both players.
- They understand that credibility is cumulative and easy to lose.
The Quick Referee Checklist
- Confirm players and format.
- Set a clean, repeatable cadence.
- Watch both hands, not just the drama around them.
- Call the round clearly and move on.
- Reset or escalate only when the situation actually requires it.
Referee the room, not just the throw
Good officiating works because players trust the process before they need to test it.
