Submission Only Rules

Overview

Submission-only rulesets strip away points, advantages, and decisions — the only way to win in regulation is by making your opponent tap. This format has gained massive popularity in professional grappling, particularly in the no-gi scene.

The philosophy is simple: jiu-jitsu is about submissions, so the ruleset should reward finishing. No more winning on advantages after a cautious match. Either you submit your opponent, or the match goes to overtime (or a draw, depending on the event).

Several organizations run sub-only events, each with their own take on what happens when nobody taps in regulation.

Popular Formats

Polaris

Matches have a set time limit (typically 10-15 minutes for professional bouts). If no submission occurs, the match is declared a draw. There are no judges, no decisions, no overtime. This rewards pure finishing ability and punishes point-fighting mentality.

EBI (Eddie Bravo Invitational) Overtime

If regulation ends without a submission, competitors enter overtime rounds:
1. One competitor starts in back control (hooks in, seatbelt grip), the other defends
2. They switch positions
3. Then one starts in spider web (armbar position), and they switch again
4. The person who escapes fastest (or submits from the position) wins
5. If still tied, the process repeats

EBI overtime guarantees a winner and creates dramatic finishes.

Who's Number One (WNO)

Matches have a time limit with no points during regulation. If no submission occurs, a panel of judges renders a decision based on aggression, submission attempts, and positional dominance. This ensures every match has a winner while keeping the sub-only spirit.

Fight to Win (F2W)

Similar to WNO — regulation is submission-only, but if time expires, judges pick a winner. F2W runs both gi and no-gi matches.

Legal Techniques & Time Limits

Legal Techniques

Most submission-only events use a very open ruleset:
- Heel hooks (inside and outside)
- Toe holds and kneebars
- Knee reaping
- Wrist locks
- Neck cranks (varies by event)
- All chokes

Some events restrict slams. Rules can vary between organizations, so always check the specific event's rules.

Time Limits

Level	Typical Duration
Amateur	5-10 minutes
Professional	10-20 minutes
Superfights	Up to 30+ minutes

Longer time limits give more opportunity for submissions to develop. Professional superfights with extended times tend to produce the most exciting matches.

Key Characteristics

Pros of Submission Only
- Rewards finishing ability over point-fighting
- Matches feature more risk-taking and scrambles
- No gaming the points system with stalling
- Comeback victories are always possible

Cons of Submission Only
- Matches can be slow when both competitors are defensive
- Without points, there's less incentive to advance position
- Draw outcomes (in Polaris-style) can be unsatisfying
- Leg lock specialists can dominate by hunting single attacks

Who Should Compete Under Sub-Only Rules

Submission-only suits competitors who have strong finishing skills. If you have reliable submissions from multiple positions, this format lets you shine without worrying about point strategy. It's also popular with hobbyists who enjoy the pure grappling aspect.
