Where the numbers come from

Players: 1900–1949: Chessmetrics estimates (Jeff Sonas, January lists). 1950–1970: Chessmetrics month by month. 1971–2026: every FIDE rating list (one or two a year at first, every month since August 2012; inactive players left out, as FIDE does). The last point is the October 2026 FIDE list. The two scales are not the same, so every line breaks between 1970 and 1971. A line stops when a player leaves the top 10.

Engines: strength on three scales. 1967–1997: USCF ratings or results of machines in human events, one point a year. 1998–2007: every dated SSDF list (commercial programs). 2008–2026: CCRL 40/15 month by month - each engine's best version released by that month (its release date), as rated on today's CCRL list. A line breaks where the scale changes, so compare heights only within one scale. A CCRL version counts only with a margin of ±16 Elo or better (about 700+ games). Leela Chess Zero is left out (CCRL rates it on CPU only), and Deep Blue (no published rating). AlphaZero (Dec 2017–Dec 2018) is an estimate: Stockfish 8's CCRL rating plus its 2018 match result against Stockfish 8 (+155 =839 −6, Science). A star (*) marks an estimate.

Sicilian Defense: O'Kelly Variation, 27 Oct 2026

Before the first move

In this position I am White against Reckless. My rook takes his bishop in the centre, and his little d-pawn gets a whole rook for lunch. I am Stockfish 19. My opponent Reckless, 4040 Elo, has the name of a stunt rider and plays like a driving instructor.Stockfish 19

Frequently asked questions

Short answers about Stockfish, the bots, the price and the site.

Free to play, no install

More help: chess guides or contact

01What is Stockfish?
Stockfish is the world's strongest open-source chess engine. Its latest release, from January 2026, is rated around 4060 Elo — +46 over the one before it — and uses the new SFNNv10 neural network.
02Is the AlphaZero on this site the real one?
No. The real AlphaZero from DeepMind was never publicly released. Our "Alpha Bot" is Stockfish tuned with custom UCI parameters to imitate AlphaZero's playing style. The disclaimer ⓘ on each card explains this.
03Do I need to install anything?
No. Everything runs in your browser. Stockfish loads via WebAssembly. Bots and analysers work fully offline once cached, even without internet.
04Does it work on iPhone and Android?
Yes. The site is built mobile-first and tested extensively on iPhone, with sound playback, theme persistence, and engine performance all optimized for mobile Safari and Chrome.
05Can I analyse my own games?
Yes. The Rama Chess Analyser accepts any PGN — paste it, upload it, or import from chess.com / lichess. It preserves variations, shows evaluation bars, and runs Stockfish locally.
06How many GM games are on the site?
Over 9,225 engine battle games at /topchessengines/, plus tens of thousands of grandmaster games organised by player at /grandmastergames/.
07Is Rama Chess free?
Yes — Rama Chess is free to play. Playing bots, 3,000+ puzzles, openings and the analyser all work for free, no account needed. Online play, profiles and saved progress just need a free account (sign in with Google). There's also an optional Premium subscription that removes ads and unlocks extra bots, boards and piece sets — but it's never required to play. The free site is supported by ads (Google AdSense).
08What is the strongest chess engine right now?
Stockfish holds the top spot at ~4060 Elo. Leela Chess Zero, Torch, and Dragon trail closely at 4010+ Elo. The gap between top engines is small but consistent.
09Can I change the chess pieces and board theme?
Yes. 17 board themes are available with a custom piece set. Visit the Customize page to change board colors, piece styles, and animations.
10Who built Rama Chess?
Rama Chess is built and maintained solo by Surajit Paul, an independent chess developer and creator of the Stockfish 100 YouTube channel. The site is not affiliated with the official Stockfish project.
