Competition Ruleset — WNO (Who's Number One)

What WNO Is

Who’s Number One (WNO) is a no-gi submission grappling promotional format produced by FloGrappling, which is the dominant grappling broadcast and media platform in the sport. WNO is not a tournament in the ADCC or EBI sense — it is a card-based event format where matches are individually negotiated and promoted, similar in structure to a boxing fight card. A typical event features four to eight matches, each between two named competitors selected for the matchup’s competitive or narrative value.

The format has been a primary platform for highly-paid, high-profile no-gi matches since its launch. Top competitors have used WNO appearances to build profile, test specific matchups outside tournament brackets, and earn purses that tournament formats do not typically pay. The result is a broadcast-driven event ecosystem distinct from the bracket-tournament ecosystems that ADCC, EBI, and CJI represent.

The Ruleset

WNO uses a submission-only ruleset for most matches, though the specific format has varied across the event’s history. Matches are typically a single fixed-length round — most commonly 15 minutes — with no points scored during regulation. If the match ends without submission, the result is decided by judges’ decision based on the criteria FloGrappling has published for the relevant event card. Some early WNO matches used pure submission-only with no judges’ decision; the addition of judges has been a deliberate adjustment to reduce the rate of unresolved matches.

Submissions follow the broader no-gi submission-only standard — heel hooks are legal, leg entanglements are unrestricted, and the format does not impose IBJJF-style submission division limits. Specific match-level rules occasionally vary; competitors and viewers should confirm the rules of the specific match rather than assuming a single standardised WNO ruleset.

The judges’ decision criteria, when applied, weigh submission attempts, positional advancement, and overall aggression — explicitly designed to penalise stalling and reward attacking grappling. This is structurally different from ADCC’s points scoring (which is mechanical and quantified) and from EBI’s escape-time tiebreaker (which is also mechanical). WNO’s judges’ criteria are interpretive, which has produced occasional controversy when results have been close.

What WNO Rewards

WNO rewards visible offensive grappling. The format does not reward positional dominance without attack — a competitor who passes guard and rides position will lose to a competitor who has been threatening submissions and advancing positions throughout the match, even if the position-rider was technically more dominant in raw control terms. The judges’ criteria explicitly favour the attacker.

The single-match format also rewards specific preparation. WNO matches are negotiated in advance and the matchup is known weeks or months ahead. Competitors prepare specifically for the named opponent — studying their game, identifying their preferred attacks and escapes, and drilling counters and entries that are matchup-specific. This is structurally different from a bracket tournament, where preparation is necessarily more general because the opponent set is determined by bracket progression rather than by named matchup.

What WNO Discourages

WNO discourages stalling, position-only games, and the strategic timeout that some bracket-tournament formats can incentivise. A competitor who establishes a dominant position and rides it to a judges’ decision is gambling that the judges will reward control over the opponent’s submission attempts and aggression — a gamble that has frequently lost on the WNO platform. The format selects against this pattern even more strongly than EBI does, because EBI at least produces a result via OT escape time, while WNO produces a result via judges’ interpretation of which competitor was more active.

The format also discourages the conservative, low-risk submission grappling that can win bracket tournaments through a series of positional decisions. WNO is a promotional format — its broadcast value depends on competitive matches with finishes or near-finishes. Competitors who consistently produce non-finishing matches are not retained on the platform.

How WNO Differs From ADCC

ADCC is a bracket tournament with a points-bearing second half of regulation and submission-only overtime. WNO is a single-match format with a submission-only or judges-decision ruleset depending on the specific match. The difference is structural — WNO is closer to a boxing fight card than to a grappling tournament. The matchups are known, the preparation is matchup-specific, and the result is a single match rather than a bracket progression.

The ruleset difference is also significant. ADCC’s points-bearing second half rewards positional achievement; WNO’s submission-only or judges-decision regulation does not. A competitor who excels in ADCC’s points half can win matches without producing submissions; a competitor who tries the same approach in WNO will most often lose.

How WNO Differs From EBI

EBI is a bracket tournament with a positional-start overtime mechanism. WNO is a single-match format with a judges’ decision (when applied) or pure submission-only (in some matches). The two formats share the submission-only regulation philosophy but diverge in how unresolved matches are decided. EBI’s OT format rewards specific drilled skill in two named positions; WNO’s judges’ criteria reward visible attacking grappling without naming specific positions. EBI specialists are therefore not, by virtue of their EBI preparation, also WNO specialists; the skill sets overlap but are not identical.

Notable WNO Events

WNO has run dozens of event cards since its launch, featuring most of the active top-tier no-gi competitors. Notable cards have included title matches in defined weight categories, “champion vs champion” matchups crossing weight classes, and one-off challenges between competitors who would not have met in a bracket tournament context. The platform has also produced “PWL” (Professional Wrestling League) and tag-team formats as adjacent properties, though these are distinct from the core WNO single-match format.

For a current view of WNO match cards, weight categories, and the specific ruleset for a given event, FloGrappling’s published event-page is the authoritative source. The platform updates rules between events and competitors should not assume the rules of one card transfer to the next.

Strategic Implications for Training

A competitor preparing for a WNO match should structure preparation around two components. First, the matchup-specific layer — film study of the named opponent, identification of their preferred attacks and escapes, and drilled counters specific to those patterns. This is the layer that distinguishes WNO preparation from generic submission-only competition preparation. Second, the format-specific layer — sustained submission threat through a long single round, awareness that a non-finishing match is decided by judges’ interpretation of activity, and the discipline to maintain attacking pace throughout the match rather than treating the latter portion as a hold-the-position phase.

The format favours competitors who can build a public profile through high-engagement matches. This is not, in itself, a technical recommendation — but it is a reality of the platform. Competitors who consistently produce decision losses or non-finishing draws are less likely to be re-booked. The training emphasis on attacking submission grappling is therefore not only a technical recommendation but a career-management one for athletes building toward sustained WNO appearances.
