Overview

Brazilian Jiu-Jitsu is a grappling sport where two competitors seek to control position and achieve submission—a joint lock or choke—for an instant win. Points accumulated through positional advancement decide the match when no submission is secured. The IBJJF governs both gi and no-gi formats under separate rulesets …

Victory priority order — Submission beats points; points beat advantages; advantages beat penalties; then referee decides.
Single-elimination bracket — Each division groups by weight, belt, and age; losses eliminate you.
Absolute Category — Open-weight division at championship level; all weight classes compete together.
Medal per category — Gold, Silver, and Bronze medals are awarded within each competition category.

Each match is contested between exactly two competitors.

Cultural norms — not in the rulebook. These are widely understood traditions and expectations among experienced Brazilian Jiu-Jitsu players. Not enforced by referees; enforced by the game’s community. Rules marked ⚡ Contested are genuinely debated even among veterans.

🚨 Cardinal Rule— Serious violation — may trigger retaliation or social exclusion

Never sandbag — compete at your true belt level
— Deliberately competing at a lower belt or division than one's actual skill level to accumulate medals is the most dishonored act in BJJ competition culture. Because IBJJF promotions are fully instructor-controlled with no mandatory timelines, some practitioners delay their own promotion to clean out lower divisions, which is widely condemned by competitors and coaches alike.(IBJJF has no mandatory promotion timelines, making sandbagging structurally easier than in arts with standardized testing.)[1][2]

⚠️ Strong Expectation— Most experienced players will take notice and be upset

Tap early in training — never ego-battle past the submission
— Refusing to tap or stalling past the clear point of being caught — known as 'ego-rolling' — is strongly condemned. BJJ culture is built on checking ego; holding out until forced or injured endangers training partners and violates the collaborative spirit of the mat. The phrase 'tap early, tap often' is a foundational cultural maxim.(This norm applies specifically to training; in competition, fighters are entitled to continue until the referee intervenes.)

Section 1: Introduction

The International Brazilian Jiu-Jitsu Federation (IBJJF) is the most widely recognized governing body for sport Brazilian Jiu-Jitsu (BJJ), administering the World Championships ("Mundials"), Pan-American Championships, European Championships, and the IBJJF World Pro circuit. IBJJF rules govern both gi (traditional uniform) and no-gi formats, with separate rulesets and weight classes. BJJ is a grappling sport where competitors aim to control position, accumulate points through positional advancement, and ideally achieve submission (joint lock or choke) for an instant win. See sibling AJP Jiu-Jitsu Rules entry for the alternative Abu Dhabi-based ruleset.

Section 8: Safety Considerations

BJJ injury profile: joint injuries (shoulder, elbow, knee), neck strain, occasional concussion. IBJJF prohibits slamming. Belt-graded submission restrictions: heel hooks, knee reaps, twisters, and other high-risk submissions only legal at brown/black belt levels (and only in no-gi, often). Referee may stop match for safety concerns. On-site EMT required at IBJJF events; medical doctor + ambulance at world-championship level. AED on-site. Concussion protocol: medical clearance required to return to competition after head impact. Pre-match medical check + mat inspection. Anti-skin-infection screening (skin checks before mat use to prevent ringworm/MRSA spread).
