Learn Chess960 from zero

Chess960 looks intimidating from the outside: the pieces start on random squares, the castling rule sounds exotic, and there are no books telling you what to do. The good news: if you can play chess, you already know 95% of Chess960 — and if you cannot play chess yet, Chess960 is arguably the friendlier place to start, because nobody can out-book you.

The rules in one paragraph

Take a normal chess set. Shuffle the white back rank under two constraints: the bishops must land on opposite-colored squares, and the king must stand somewhere between the two rooks. Mirror the arrangement for black. That gives exactly 960 legal starting positions — hence the name. From there, every piece moves exactly as in classical chess; check, checkmate, stalemate and promotion are unchanged. The only rule with a twist is castling.

Castling in Chess960: the king and rook end up on the same squares as in classical chess — king on g1 with rook f1 (short), or king on c1 with rook d1 (long) — no matter where they started. The squares between must be free and not attacked. It is easier to feel than to read about, which is why we built a dedicated trainer: castling trainer. The full write-up with edge cases lives at Castling in Chess960.

A learning path that actually works

CH960 is a free app and website for exactly this. The learning loop is fully offline-capable and never paywalled. What we recommend:

  • Start with the interactive lessons — rules, board vision, first tactics: Learn hub.
  • Do the castling chapter early; it is the one genuinely new skill: castling trainer.
  • Then one day at a time: the 1000-day course mixes a lesson with ~30 puzzles tuned to your level — day 1 is here.
  • Keep a daily rhythm with the puzzle of the day.
  • In the app, play the mentor ladder: ten characters from beginner to strong club level, with hints, level advice and undo — bots are always labelled as bots.

Every puzzle you will meet is engine-verified (Stockfish, depth 20+) and most are mined from real self-play games in all 960 positions — the pipeline is documented openly on the methodology page.
