A rating you can
take anywhere.
Crest is the open, sport-portable rating standard for padel — and the format every other sport is going to want next. 0–3000 on a single scale, mapped to Iron → Sovereign tiers, computed with the same engine top esports use, gated by a real integrity layer.
§ 01 / what it is
One scale. Nine tiers. Open engine.
One scale
0 to 3,000
Every player on a single ladder. No regional resets, no separate beginner pool — your Crest is yours wherever you play.
Nine tiers
Iron → Sovereign
Each tier covers ~400 points. Moving up means something material — not "you went from 1462 to 1471".
Open engine
OpenSkill (Weng-Lin)
Handles 1v1, doubles, N-player races, team formats. Replayable from the audit log. No magic.
§ 02 / the ladder
Nine tiers. One scale.
Per-discipline thresholds calibrate as the player population grows.
Unranked
Just starting — provisional Crest until you stabilise σ.

Sovereign
Best-in-world. The rating tells the room before you walk in.

§ 03 / integrity
A three-layer integrity ladder.
Every result passes through provenance scoring, statistical anomaly detection, and graph-collusion checks before it counts. Sandbagging and pump-tank rings get caught before they reach a leaderboard.
Layer 1
Provenance
Federation > operator > confirmed > bilateral > self.
Layer 2
Anomaly detection
Rating jumps + σ collapse + engineered win/loss patterns.
Layer 3
Graph collusion
Dense clusters + pumping rings + coordinated tanking.
§ 04 / locked invariants
What the rating never does.
Never includes minors.
Adult age threshold is country-aware (strictest if blank). Under-18 accounts are physically absent from the public surface — not just hidden in code.
Never includes private accounts.
Public visibility is opt-in. Turn it off and your handle returns 404 — no shadow profile, no API leak.
Never derived from credits or spending.
Credits buy access, cosmetics, competition entry. They do not — by code, not by policy — move a single Crest point.
Never includes Article 9 tags.
Identity, condition, or preference tags live in a protected store + never appear in any public surface or commercial feed.
Never sold with identifiers attached.
Aggregate sales are de-identified with a minimum-cohort rule (≥5 players per cell). Identified data needs an explicit opt-in + a license-bound buyer.
Never gates community on rating.
You can post, follow, attend, organise, play — none of it requires a Crest. Rating is a measure, not a key.
§ 05 / FAQ
What people ask first.
How is Crest different from Elo or DUPR?+
Crest is built on OpenSkill (Weng-Lin) so it handles team play + N-player races correctly. Elo is two-player only. DUPR is closed-source + pickleball-only. Crest is sport-agnostic + transparent — every step from match-result to rating-update is replayable from the audit log.
Why 0–3000?+
It maps cleanly to the OpenSkill ordinal (μ − 3σ) and gives meaningful headroom — your Crest goes up + down by tens, not by hundredths. Each tier covers ~400 points, so a single move feels material.
Can I take my Crest to other platforms?+
Yes. The public Crest API is keyless for single-player lookups + open to embed (badge SVG, JSON). Booking platforms, club apps, fantasy sites — anything that wants your rating can read it. See the data licence + developer portal for terms.
What stops people gaming it?+
A three-layer integrity ladder. Layer 1 weighs provenance (federation > operator > opponent-confirmed > self). Layer 2 watches for statistical anomalies (sandbagging, σ collapse). Layer 3 looks across the match graph for collusion clusters. Failure quarantines the row from commercial feeds + may freeze the rating while we investigate.
How often does it update?+
Every confirmed match. Your Crest changes the moment the score is settled — usually within seconds. The audit log keeps a stamp of every change, replayable end-to-end.
Ready when you are
One confirmed match.
Your rating goes live.
Host a game or join an open game on TrustPadel. After both teams confirm the score, your first Crest publishes within a few seconds.
