Grappling Industries is known for round-robin brackets: in a small division you fight everyone, not just one opponent. Its scoring looks like IBJJF but drops advantages and adds 2 points for a submission attempt stopped out of bounds. This guide covers the official rulebook (2026-02-09 edition), with a legal-move table generated from the Open BJJ legality matrix. Last verified 2026-11-01.
The short version
- Divisions go by belt. You must register at your gi belt, and in no-gi you may enter a higher level if you want.
- Brackets of 2 to 5 people are best-of-3 or round robin, so most competitors get at least 2 matches.
- Adult, masters and seniors matches are 5 minutes. No overtime.
- Points: 4 mount, 4 back, 3 pass, 2 sweep, 2 takedown, 2 knee on belly, 2 for a strong submission attempt stopped out of bounds. No advantages.
- No weight allowance. Weigh in up to at least 60 minutes before your division.
Divisions and skill levels
Adult divisions are named by belt and skill level together, for example “Adult White Belt/Beginner” and “Blue Belt / Intermediate”. You must register at the belt you hold in the gi (unless you are required to compete higher). In no-gi you may freely register above your rank. The rulebook does not give years-of-experience equivalents for no-gi levels. It uses the same belt-based levels.
Athletes with significant experience in other grappling arts must enter at Blue Belt / Intermediate or above. The rulebook names judo black belts, high-level collegiate wrestlers (for example NCAA Division 1), senior-level international wrestlers, experienced catch wrestlers, luta livre blue belts and above, and professional MMA fighters. Exceptions are possible, for example a lower-tier collegiate wrestler with limited experience.
Sandbagging, competing below your rank, means being moved up before event day or disqualified on the day, and can lead to a suspension or ban. Staying at one belt for a long time without promotion is not sandbagging.
Kids levels pair belts with skill names for ages 15 and under: White/Beginner, Grey/Intermediate, Yellow/Orange/Advanced and Green/Expert. Ages 16–17 use a single coloured-belt level. Kids aged 15 and older may move to adult on request: white and grey belts to adult white belt, yellow and above only to adult blue belt. Masters may enter adult, and seniors may enter masters or adult. Under-30s cannot be merged into masters, and under-40s cannot be merged into seniors. Absolutes are 18 and over only.
Round robin and bracket format
Bracket size sets the format. Brackets are randomised and teammates are not kept apart.
Group and division winners are decided in this order: most wins, most submissions, the head-to-head match, most points scored, fewest points scored against. A submission win therefore counts for more than a points win when records are level.
| Competitors in division | Format | Matches per competitor |
|---|---|---|
| 2 | Best 2 out of 3 | 2 to 3 |
| 3 | Round robin | 2 |
| 4 | Round robin | At least 3 |
| 5 | Round robin | 4 |
| 6 to 9 | Groups, top 2 advance to a final | 4 to 5 |
| 10 or more | Groups, top 4 advance to semi-finals and a final | 4 to 6 |
| Absolutes | Single elimination | Varies |
Match times
There is no overtime in the rulebook. The referee may end a kids match early for safety.
| Division | Match |
|---|---|
| Adult, masters and seniors (every belt) | 5 minutes |
| Kids and teens aged 14–17 | 4 minutes |
| Kids 13 and under | 3 minutes |
Points, no advantages and tie-breaks
Section 6.2 lists the whole system. Every position must be held and controlled for 3 seconds.
“There is no Advantage scoring.” A tie on points goes to the competitor with fewer penalties, and if that is level too, to a referee decision.
The values match IBJJF for positions, so understanding IBJJF points is a good primer. The difference is that near-misses earn nothing here. For a scoring system built the other way round, see ADCC rules explained and IBJJF vs ADCC rules.
| Action | Points | Notes from the rulebook |
|---|---|---|
| Mount | 4 | Sitting on the torso, belly up or down. No points if both of the opponent’s arms are trapped |
| Back control | 4 | Heels between the thighs, feet not crossed, plus an upper-body lock. A body triangle does not score |
| Guard pass | 3 | No points if the bottom player turtles for 3 seconds in response |
| Sweep | 2 | From 50/50, the sweeper must come up standing with the rear knee off the mat |
| Takedown | 2 | Opponent lands on back, side or seated, or into turtle only if on all fours with you behind |
| Knee on belly | 2 | Knee or shin on the upper body, other knee off the mat, opponent on their back |
| Submission attempt stopped out of bounds | 2 | Not if the defender was forcing the action off the mat to escape |
Legal moves by division
Generated from the Open BJJ legality matrix, which reads each cell from the rulebook’s Legal Techniques chart.
Reading the table left to right: straight ankle locks, wrist locks, Ezekiels and standing guillotines are illegal under 18 and legal at adult white belt. Knee bars, toe holds, knee reaping and slicers are illegal at white belt and legal from blue belt. Neck cranks are legal from purple belt in no-gi and brown belt in the gi. Heel hooks and the scissor takedown are legal only in the no-gi purple, brown and black column.
Attempting a technique that is not allowed at your level is a disqualification. Each cell links back to its rule in the submission legality matrix, next to the IBJJF, ADCC and NAGA columns.
| Technique | Under 18 | Adult white belt | Blue belt and purple in the gi | Purple, brown and black in no-gi | Brown and black in the gi |
|---|---|---|---|---|---|
| [Straight ankle lock](/submissions/straight-ankle-lock) | illegal | legal | legal | legal | legal |
| [Wrist lock](/submissions/wrist-lock) | illegal | legal | legal | legal | legal |
| [Ezekiel choke](/submissions/ezekiel-choke) | illegal | legal | legal | legal | legal |

Penalties to know
- Knee reaping, under 18 and adult white belt/beginner: the first reap without a submission is a penalty and the referee removes the reap. A second one, or a reap combined with a submission, is a disqualification.
- Guard pull without a grip: pulling guard without a grip on the opponent is a penalty, and the action restarts standing. This applies at every level.
- Slams: a slam is lifting the opponent and returning them to the mat in an uncontrolled way. Controlled suplex-style takedowns are not slams, but spiking the head or neck is not allowed.
- Stalling: the referee may call it after 20 seconds of inactivity or no intent to improve position.
- Progression: for minor fouls the first penalty is a warning, the second gives the opponent 2 points, and the third is a disqualification. Major fouls are an immediate disqualification, and any third penalty of any kind disqualifies.
Weigh-in
Check in and weigh in any time up to at least 60 minutes before your division starts. There is no weight allowance: weigh in at or under the limit or you are disqualified, and you will not be moved up a class. Gi competitors may weigh in without the gi. If you enter both gi and no-gi you weigh in once, and absolute or no-limit entrants still check in at the weigh-in desk.
