# Volleyball Rotation Rules Explained
Volleyball rotation is one of the most misunderstood aspects of the game. As a certified referee, I'll break down everything.
## The Six Court Positions
Position 1 (Right Back/Server) through Position 6 (Middle Back), arranged in two rows of three.
## Rotation Direction: Clockwise
1 → 6 → 5 → 4 → 3 → 2 → 1 after each side-out. Players rotate clockwise, not counterclockwise.
## Overlap Rules
**Front-to-back:** P4 ahead of P5, P3 ahead of P6, P2 ahead of P1.
**Side-to-side:** P4 left of P3, P3 left of P2, P5 left of P6, P6 left of P1.
## The Libero
Free substitution for back-row players. Cannot serve (most rules), cannot attack above net, must sit out one rally between replacements.
## Rule Set Differences
| Rule Set | Libero Serving | Substitution Limit |
|----------|---------------|-------------------|
| FIVB | Not allowed | 12 per set |
| NCAA | Allowed (1 pos) | 15 per set |
| NFHS | Allowed (1 pos) | 18 per set |
## FAQ
**Can players switch after serve?** Yes — once the server contacts the ball, all players move freely.
**Why different colored jerseys?** To track libero substitutions.
**What if wrong rotation?** Rotational fault — loss of rally, possible point cancellation.
