Frequently Asked Questions

From public battle logs, read through the official Clash Royale API. Every statistic on the site comes from battles that were really played.

A battle has two decks, so we record both sides and remove duplicates. A deck that wins and a deck that loses each get their game counted.

Several times a day. Deck and card lists refresh after each update, and you can pick the last 24 hours, 7 days or 30 days on the main lists. A deck page always shows the last 7 days.

We collect battle logs from a very wide range of players, and we count both sides of every battle. When we compare the same decks in the same game modes, we record several times more Ranked games and more than ten times as many Ladder games than RoyaleAPI. You can check by opening the same deck on both sites.

No. DeckRoyale is an independent fan site. It is not affiliated with, endorsed, sponsored or specifically approved by Supercell.

A popular deck is played by everyone who copied it, including players still learning it. It also meets opponents who know how to beat it, and many mirror matches, which pull its win rate toward 50%. A low win rate on Ladder often says more about who plays a deck than about the deck itself. To judge a deck, look at its Ranked win rate.

Ladder shows what the most players use, so it is good for popularity. Ranked win rates are a better signal of how strong a deck really is.

The Meta-Meter shows how far a deck stands from an even 50%, after weighing its win rate by how much it has been played. A deck with few games is pulled toward 50% until its record backs it up. A value of +3.0 means a weighted win rate of 53%.

Low Sample means fewer than 300 games: the win rate can still move a lot. Small Sample means fewer than 1,000 games: treat the win rate as a rough guide, not a verdict.

Auto picks the highest minimum number of games that still leaves enough reliably winning decks to fill the page. It starts at 10,000 and goes lower for smaller modes and narrow filters.

A 2v2 win rate is the team's, so it also depends on the partner's deck. Read it as how well a deck does with its partners, not on its own.

A deck needs at least 100 games across 1v1 modes in the period before it is processed. A new or unusual deck may not have reached that yet.

Lists show only what was really played. If an event does not use Evolutions or Heroes, those cards have no games, so they are left out of its stats.

Name search only covers players already in our data. If an account is missing, enter its full player tag. The tag is under your name in the game, on the main screen.

No. You can browse the statistics without one. An account lets you save decks, publish them and write guides.
