About Clashest

What Clashest is

Clashest tracks the Clash Royale meta: top decks, card usage and win rates, player and clan profiles, leaderboards, and tournaments — presented as a clean dashboard instead of a wall of banner ads. It is a fan-made project and is not affiliated with, endorsed, sponsored, or approved by Supercell.

Where the data comes from

Every number on this site traces back to the official Clash Royale API (developer.clashroyale.com) — and nothing else. Live lookups (players, clans, leaderboards, tournaments) are proxied straight from the API. Aggregate stats (deck win rates, card usage, meta trends) are computed from battle logs we ingest from highly-ranked players' recent matches, deduplicated and stored with their timestamps.

We never fabricate or extrapolate stats. If a view doesn't have enough real battles behind it, we say so: every displayed aggregate carries its time window and battle count, and views with thin samples render an explicit "not enough battle samples" state instead of a made-up number.

Rating methodology

The Clashest deck rating is a 0–100 score designed to reward decks that win reliably, not decks that got lucky over a handful of games. It is computed exactly as follows:

1. Wilson lower bound.We take the lower bound of the 95% Wilson score confidence interval of the deck's win rate (z = 1.96). This is the sample-size penalty: a 60% win rate over 20 battles scores below a 55% win rate over 2,000 battles, because we're far less certain of it.
2. Core score (0–80 points). The Wilson lower bound is centered on 50%: core = clamp(40 + (wilsonLB − 0.5) × 400, 0, 80). A 50% lower bound gives 40 points; a 60% lower bound reaches the 80-point cap.
3. Usage signal (up to +12 points). usage = clamp(12 + log₁₀(usageShare) × 4, 0, 12). A 0.1% usage share adds ~4 points, 1% adds ~8, 10% adds ~12 — popular decks have proven themselves against a wider variety of opponents.
4. Recency (up to +8 points). recency = clamp(recentShare × 16 − 4, 0, 8), where recentShare is the fraction of the deck's battles in the most recent half of the window. Decks trending now edge out decks that peaked last week.
5. Clamp. The sum is rounded and clamped to 0–100.

Decks with fewer than 10 battles in the window get no rating at all, and we treat 50+ battles as the minimum for ranking placement. Sample-size badges (high / medium / low) appear alongside stats so you always know how much data backs a number.
