The official weigh-ins will be conducted without the gi for all matches but some form of underwear must be worn (no athlete will be allowed to weigh-in without). Athletes must make the weight agreed for the bout. Failure to do so may result in the bout being cancelled.

Corner Team

Each club with between 1 and 2 competitors will be allowed one coach pass backstage at the event.
Clubs with 3 or more competitors will be allowed two coach passes backstage at the event. However only one corner person will be allowed matside during each match.

Sub Only Rules Contests

Main event bouts, tournament finals and title matches have a 15 minute duration

All non main event bouts will have a ten minute duration.

The ruleset is designed to allow the athletes to use the skills they have obtained in their chosen grappling art, to bring excitement to the audience and showcase grappling in the most dynamic and interesting way possible, and to determine a winner in cases where there is no submission victory.

Our judges will decide the winner of the bout based on the following guidelines, positive and negative. 

The categories are in descending order of importance with A being the most important and carrying the most weight.


A) Effective Attacks and Aggression

  • Legitimate submission attempts that cause the opponent to apply effort to escape

  • Pushing the pace of the bout

  • Initiating exciting exchanges

  • Taking risks in an attempt to gain a takedown, advantageous position or submission attempt

Note on submission attempts:

The definition of a legitimate hold is that the opponent has to apply effort or take a risk in order to escape. If a fighter uses a submission attempt as a positional stalling tactic (e.g. holding on indefinitely to a submission that they are not able to finish) then this would not be looked upon favourably.

B) Escalating Positional Control

  • Takedowns

  • Sweeps

  • Improving position in order to set up a submission

C) Effective counter attacks and dynamic escapes

  • Effectively countering takedowns

  • Reversals

  • Spectacular escapes


D) Stalling and Passivity

  • Not capitalising on good positions

  • Constantly moving backwards

  • Exiting the competition area

  • Being overly defensive and unwilling to take risks

  • Not attempting to advance position

E) Poor sportsmanship / fouls

  • Attempting illegal submissions or manoeuvres

  • Striking

  • Any other breach of the rules

  • In extreme cases the referee may disqualify or indicate that the judges are to mark a fighter down, at his discretion


The judges is encouraged to always look upon the aggressor / attacker more favourably than the defensive fighter.

Stalling and passivity are strongly discouraged and the referee should score appropriately, penalising any kind of stalling tactic that slows down the action.

If there is no submission the bout will be decided by judges decision. 


Where a fighter sustains an accidental injury during the match, they will be given up to 5 minutes to recover. The timekeeper will stop the time during this. If the fighter indicates they are able to continue before the 5 minutes is up then the match can resume.

If the player is unable to recover during the 5 minutes then the match will be declared no contest and the injured fighter will receive medical assistance off-stage.

If medical intervention is necessary then the judges and referee can confer with the medic to decide if the bout can continue.

If the injury is sustained via an illegal manoeuvre, a negative point will be given to the perpetrator and the fighter given up to 8 minutes to recover. The timekeeper will stop the time during this. If the fighter cannot recover then the bout will be declared a win for the injured fighter.

Poor sportsmanship / fouls / passivity

Upon an infraction, the referee will pause the bout, warning the fighter (s) and pointing to the fighter (s) who is receiving a warning, and then the three judges one by one.

After two infractions, or at the referee’s discretion, the match can end, with the fighter committing the offences being declared the loser, and the opponent the winner.


Illegal Methods / Movements

Eye gouging or fish hooking

Grabbing fingers, ears, hair, toes, or other extremity

No posting on faces / one-handed windpipe grip

Slamming from above the knee height of the person doing the lifting to escape a submission or position (high amplitude throws / takedowns will not be penalised)

Disrespectful conduct towards referee, event staff, opponent or opposing coach

Legal Techniques

Chokes (except using fingers to crush windpipe)

Joint locks involving shoulder, elbow, wrist, knee, ankle. Neck cranks & heel hooks are legal in no-gi bouts.

Gi bouts legal submissions as per IBJJF for belt level. Illegal in gi bouts: Cervical locks, heel hooks are illegal at all levels in Gi bouts.

General Rules

Winner is signified via tapout (at least two rapid taps on the opponent or mat), verbal submission (voluntary or involuntary(any exclamation of pain, scream, gasp etc counts as an involuntary submission)), or being unable to continue the bout due to injury.

In no-gi bouts the athletes must not grip any clothing

Referee will be on the mat to officiate the bout, ensure rules are followed and advise fighters when they get too near the edge of the mat, in which case they will be paused and returned to the centre of the mat in the same position. If no agreement on positioning can be made the athletes will be stood up at the centre of the ring. In the event of a submission attempt rolling out of bounds both athletes will be restarted standing.

Overall a high standard of sportsmanship is required before, during and after the fights.

Square go Team Elimination rules

Each team will consist of 5 members with a maximum combined weight of 420kg.
Team captains will submit the fight order for their team prior to the start of the match.
Competitors will match off in the order they are selected. The winner of each bout stays on until an entire team has been eliminated.

Ways to Win

By submission
By decision (in the event of a time limit draw the athlete with least penalties will advance. If both competitors have an equal number of penalties then both are eliminated)

In case of the same number of warnings in the last fight, the team with the lowest total warnings wins. In case of the same total warnings, the referee determines the result from the last fight by means of hand gesture.
