What Crown Score does

Crown Score is a CrownLab tool by CrownStats that turns a Clash Royale player's recent form, deck consistency, matchup results, card levels and upgrade pressure into one transparent 0–100 snapshot of current competitive readiness. It is not a rating of raw skill.

Crown Score answers "how are things going with my current setup right now?" with one number and five visible parts. Each pillar is calculated from the same recent battles and card levels the other CrownLab tools use, each shows the sample it came from, and the score is only produced when enough pillars have real data.

Crown Score is not a rating of your raw skill. It measures statistical signals CrownStats can observe around a player's setup and recent battles; timing, placement, prediction and decision-making inside a battle are invisible to it and still decide every match.

What Crown Score analyses

Recent Form — win rate across analysed recent 1v1 battles (up to 30 points)
Deck Consistency — the share of recent battles played with one main deck (up to 20 points)
Matchup Health — personal win rate across repeated opponent archetypes (up to 20 points)
Level Readiness — the share of comparable battles not played at a card-level disadvantage (up to 20 points)
Upgrade Readiness — the strongest current-deck upgrade case, inverted, so lower upgrade pressure scores higher (up to 10 points)

How CrownStats calculates Crown Score

Each pillar has its own availability gate. Recent Form needs at least 5 analysed 1v1 battles; Deck Consistency needs 8 battles with a usable deck; Matchup Health needs 2 qualifying archetypes and 4 encounters; Level Readiness needs comparable card-level data; Upgrade Readiness needs a complete current deck.
A pillar without enough data is left out of both the points earned and the points available — never counted as zero — so missing data lowers coverage, not the score.
The score is points earned divided by points available across the pillars that were measured, scaled to 100. It is produced only when Recent Form is available and at least 3 of the 5 pillars are; otherwise Crown Score reports insufficient data rather than a fabricated number.
Labels: Strong Position at 90 or more, Solid Position at 75, Building Momentum at 60, Mixed Signals at 45, and Focus Areas Found below that.
Up to 3 positive drivers and 3 focus drivers name the specific figures pushing the score up or down, each drawn from the same inputs the pillars use.

Key terms

Crown Score: CrownStats' 0–100 snapshot of current competitive readiness, built from five measured pillars. It is not a skill rating, not a universal player rating and not an official Supercell score.
Pillar: One of the five measured components. Each has a maximum, an availability gate and its own sample.
Coverage: How many of the 5 pillars had enough data to be measured, shown as "N / 5 pillars measured". Missing pillars reduce coverage, not the score.
Driver: A specific figure — a win rate, a deck share, a level-disadvantage share, an upgrade case — that pushes the score noticeably up (positive) or down (focus).
Upgrade pressure: The strongest upgrade case in the current deck, as Upgrade Advisor measures it. High pressure means a clearly under-levelled card exists, which lowers Upgrade Readiness.

What Crown Score cannot see

Crown Score is not a rating of your raw skill. It is not a universal player rating, and it is not an official Supercell score.
It describes the recent battle-log sample and the current deck. It is not a career rating, and it can change as new battles are played and older ones roll off the log.
Matchup Health uses personal results only; Matchup Scout's global data and Rival Tracker never affect the score.
What the score cannot see: every placement, prediction, elixir decision or timing choice inside a battle. One card placed a tile differently can change an entire match.

Sample size and evidence

Coverage is always shown as "N / 5 pillars measured", and each pillar states the sample it used — battles analysed, comparable battles or qualifying archetype encounters.

Where the data comes from

CrownLab reads a player's profile, current deck, card levels and recent battle log through the Official Clash Royale API. It combines them with CrownStats' own card-stat dataset (per-level damage, hitpoints and related values, kept current with balance corrections) and, where a tool uses it, CrownStats' aggregated deck statistics from the battles it has collected. Nothing is estimated from a source CrownStats does not have.

Every personal CrownLab result is computed on demand from the recent battles the Clash Royale API currently returns for that player — a recent sample, not a stored career history — so a result can change as new battles are played and older ones leave the log.

CrownLab recommendations, Crown Score and Upgrade Advisor's rankings are CrownStats' own formulas. They are not official Supercell ratings or recommendations, and they are not a measure of a player's raw skill.

The personal CrownLab tools run on the Clash Royale player tag linked to a signed-in CrownStats account. Interaction Lab needs no account and no tag.

CrownStats is an independent project, built and maintained by one developer. It is not affiliated with, endorsed by or sponsored by Supercell. Clash Royale is a trademark of Supercell.

Frequently Asked Questions

How is my Clash Royale deck performing right now?

Crown Score does not rate a deck in the abstract. It measures how your current setup is doing in your recent battles — form, consistency, matchup results, card levels and upgrade pressure — and shows each part with its sample. For how a specific deck performs across many players, see that deck's own CrownStats page.

How does CrownStats calculate Crown Score?

Five pillars — Recent Form (30), Deck Consistency (20), Matchup Health (20), Level Readiness (20) and Upgrade Readiness (10) — each earn points from your recent battles and current deck. Pillars without enough data are excluded from both sides of the fraction, and the score is earned points over available points, scaled to 100. It is only produced when Recent Form and at least 3 pillars in total are available.

Is Crown Score my skill rating?

Crown Score is not a rating of your raw skill. It reflects statistical signals in your recent battles and current deck. Two players with the same skill can have very different scores depending on what they played recently, and a score can change simply because older battles left the log.

Why is my Crown Score unavailable?

Crown Score needs Recent Form — at least 5 analysed 1v1 battles — plus at least 2 more pillars with enough data. Until then it shows insufficient data and lists each pillar's status, rather than inventing a number from too little.

Why did my Crown Score change when I didn't change anything?

Because the recent battle log changed. Every pillar except Upgrade Readiness is computed from the battles the Clash Royale API currently returns; as new battles arrive and older ones roll off, the win rates, deck shares and level comparisons behind the score move with them.

Is Crown Score an official Supercell rating?

No. Crown Score is CrownStats' own formula, published in full on this page. It has no connection to trophies, Path of Legends, or any rating Supercell maintains.
