Clash Royale RoyaleAPI replay corpus

Raw and cleaned Clash Royale battle replays captured from RoyaleAPI via the clash-royale-ai collector pipeline. Used to train the winner predictor model.

Path	Description
`raw/`	15,420 verbatim `/data/replay` JSON captures (schema v1), sharded into `raw/00/`, `raw/02/`, `raw/08/`, and `raw/09/` subdirectories (Hugging Face file-per-directory limit). Each file contains the full RoyaleAPI replay HTML payload: timeline card plays, map markers with arena coordinates, elixir/leak tables, and deck stats.
`card_costs.json`	Official elixir costs keyed by card slug (used for feature extraction).
`cleaned-legacy/`	Processed December 2025 legacy subset: `matches.jsonl`, `events.jsonl`, `manifest.json`, `quarantine.jsonl` with Hero/Champion ability labeling.

Raw replay format

Each file in raw/ is named {battle_tag}.json:

  }
}

The HTML embeds:

Timeline events: data-card, data-t (tick), data-s (blue/red), data-ability (0=play, 1=ability)
Map markers: data-x, data-y, data-c, data-t for arena placements
Elixir tables: troop/spell/building/ability counts and leaked elixir per side

Ticks convert to seconds as ticks / 20.

Limitations

Replays are sourced from RoyaleAPI's public leaderboard crawl; player tags and usernames appear in the HTML.
Not all captures are valid battles (Cloudflare challenges, rate-limit errors, etc.). The cleaning pipeline quarantines these.
Replay actions do not include live unit HP, positions over time, or projectile state—only discrete play/ability events.
Meta coverage reflects the collection window (2025–2026); older cards and balance patches may be underrepresented.
