How Royal Rank works

Royal Rank rates Clash Royale players by real skill. Its rating, CRSR (Clash Royale Skill Rating), estimates how well you actually play: not how long you've played, how much you've spent, or how maxed your cards are.

What CRSR means

CRSR is a decimal score with no maximum. A typical ladder player sits around 5.143, players at the Ranked entry bar around 6.857, and established Ultimate Champions around 9.429. Every profile shows the rating with a ± range: how certain we are of it.

Why it isn't trophies

Trophies and Ranked medals reward playing a lot and winning streaks against whoever the matchmaker finds. Two players with the same trophies can be very different players: one may have maxed cards and thousands of games, the other may be climbing fast on a fresh account. CRSR looks at how likely you were to win each match and whether you did better or worse than that.

What goes into every match

• Opponent strength. Beating a strong player is worth more than beating a weak one; losing to a much stronger player costs little.
• Deck matchup. Some decks counter others. Royal Rank learns how decks and deck styles do against each other from the battles it collects, so winning a bad matchup counts for more.
• Card levels. Winning while under-levelled says more about skill than winning with a level advantage. In modes where levels are equalised, levels don't count.
• Competitive level. High-level Ranked and ladder matches count fully; low arenas, casual and special modes count less, so the rating can't be farmed.

Every rating change on a profile is broken down into these parts, so you can see exactly why it moved.

Confidence and new players

New players start provisional: their rating moves quickly while we learn their level, using their trophies and Ranked history as a starting point. As matches accumulate the rating settles, and an established player's CRSR changes only a little per game. Taking a break never lowers your rating, but confidence fades until you play again. The leaderboard only shows players we're confident about.

How ratings move

Before each match we estimate your chance of winning. Win a match you were expected to lose and CRSR rises noticeably; win one you were expected to win and it rises a little. Clash Royale has real variance, so the estimate never treats any match as a sure thing, and an occasional upset loss never costs more than it should.

Limitations

• Royal Rank only sees battles from the official Clash Royale API, which keeps a player's last 25 or so battles, for players it tracks and their opponents.
• Ratings for players with few recorded matches are rough; that's what the ± range and the provisional label are for.
• Royal Rank is an unofficial fan project and isn't affiliated with or endorsed by Supercell.

Questions

How good am I at Clash Royale?

Find yourself with the search box. If you're not on Royal Rank yet, add your player tag; your profile appears after the next update and firms up as you play Ranked and Trophy Road.

Is CRSR like an Elo rating?

It's in the same family as Elo and Glicko skill ratings used in chess and esports, adapted to Clash Royale: it also accounts for deck matchups, card levels and how competitive each match was.

How do I get on the leaderboard?

Play enough recent, competitive matches for your rating to become confident. Profiles show your progress toward that. See the global leaderboard.
