IBJJF Rules Explained: Complete Ruleset Guide

IBJJF Points System

IBJJF uses a points-based scoring system where different positions and movements score different values. Submissions are instant wins regardless of score.

• Rear mount (back control with hooks): 4 points
• Mount: 4 points
• Guard pass: 3 points
• Knee-on-belly: 2 points (must hold 3 seconds)
• Sweep from guard: 2 points
• Takedown: 2 points

Points are only scored when a position is stabilized (held for 3 seconds). Positions held for less than 3 seconds may score an advantage instead.

Advantages

Advantages are scored for near-scoring situations — a submission attempt that nearly works, a position held briefly, a takedown that doesn't fully materialize. Advantages are tiebreakers only — they don't override points.

Situations that generate advantages:

• Submission attempt that makes opponent react or defend strongly
• Position held less than 3 seconds
• Takedown that results in the opponent going to guard immediately
• Near sweep that doesn't complete

Illegal Techniques by Belt Level

IBJJF restricts certain techniques based on belt and age division. These restrictions exist for safety reasons. Understanding them is essential before competing.

White Belt (Adult)

• No heel hooks, knee bars, calf slicers, or spine locks
• Straight ankle locks are legal
• No reaping the knee

Blue and Purple Belt

• Same as white belt — heel hooks, knee bars, calf slicers still illegal
• Straight footlocks (ankle locks) are legal
• Toehold is legal at blue/purple in gi; illegal in some no-gi divisions

Brown and Black Belt

• Knee bars and calf slicers are legal
• Inside heel hook is legal in no-gi; outside heel hook is still illegal in IBJJF
• Spine locks without chokes are still illegal at all levels

Always Illegal (All Levels)

• Slamming
• Striking
• Neck cranks
• Spine locks
• Outside heel hook in gi at all belts; in no-gi at all belt levels
• Scissors takedown (flying scissors to the knee)

Penalties

IBJJF has a penalty system for stalling, unsportsmanlike conduct, and illegal techniques:

• First penalty: Advantage given to opponent
• Second penalty: 2 points given to opponent
• Third penalty: 2 more points to opponent
• Fourth penalty: Disqualification

Stalling is one of the most common penalty situations. Referees warn practitioners who aren't working to progress the match — particularly when holding a position without attempting submissions or transitions.

Illegal technique application results in immediate disqualification, not just a penalty.

Match Duration

IBJJF match times vary by belt and age:

• White belt adult: 5 minutes
• Blue belt adult: 6 minutes
• Purple belt adult: 7 minutes
• Brown belt adult: 8 minutes
• Black belt adult: 10 minutes
• Masters divisions: Slightly shorter, varies by division

Tiebreakers

When the match ends tied on points, tiebreakers apply in this order:

• Advantages (whoever has more wins)
• Penalties (fewer penalties wins)
• Referee decision (last resort)

Referee decisions are controversial but a reality of the sport. Understanding advantages and minimizing penalties is critical in close matches.

Guard Pull Rules

A guard pull occurs when a practitioner sits to guard without a takedown attempt. In IBJJF:

• Pulling guard without engaging in a takedown first does not give the opponent any points
• The opponent standing while you pull can pursue a guard pass for 3 points
• If you pull guard and immediately sweep, you score 2 points
• If the opponent achieves standing while you have guard, and then you sit again, you can receive a stalling penalty

No-Gi IBJJF Rules Differences

IBJJF no-gi follows the same points structure with these key differences:

• No collar, sleeve, or lapel grips (no gi = no grips on fabric)
• Inside heel hook legal at brown/black belt
• Toehold restrictions differ by division
• No reaping the knee rules remain consistent with gi
