Play chess against the computer

ChessLounge's own chess engine offers 36 levels, from 900 to 2650 Elo. Whether you're a beginner picking up chess for the first time or looking for a real challenge, there's always a chess bot at the right level for you.

Play against Stockfish 19

Besides its own engine, ChessLounge also supports Stockfish, one of the world's strongest chess engines – adjustable from 1320 to 3190 Elo and available as an optional download.

A personal chess coach for beginners

Turn on the Coach: he warns you about risky moves or occasionally offers a tip. A relaxed way to learn chess, especially if you're just starting out.

Chess with friends

Create a password-protected room and meet your friends there online for a game of chess. If you'd rather get together in person, you can also play two-player chess on the same device.

Works on every device — no download needed

Play in any browser on phone, tablet, or desktop, all with the same interface. Install the app for quick access if you like, and sync a game to the cloud to resume it on another device where you're signed in.

Play on your electronic chessboard

Connect a Chessnut or Millennium chessboard via Bluetooth and make your moves on the real board. Works in Chrome and Edge on computers and Android devices.

Free and ad-free

No costs, no ads – and still full privacy. ChessLounge is funded entirely by voluntary donations.

Frequently asked questions

Is ChessLounge really free?

Yes. Every feature is free, with no ads and no paywall. ChessLounge runs on voluntary donations.

Can I play chess against the computer without signing up?

Yes. Open ChessLounge and start a game — no account needed. An account is only required for rated games, online rooms, and cloud sync.

How do I play chess online with a friend?

Both of you create a free account. One of you opens ChessLounge Online and creates a room with a name (and a password if you like); the other joins with the same name. Then you play — and can chat — in your private room.

Can two people play chess on the same device?

Yes. Choose “Player vs. player” — two players, same device — and take turns on the same board. ChessLounge checks the rules, detects checkmate and draws, and shows both players' thinking time – with or without a time limit.

What level should I choose as a beginner?

Start at one of the lowest levels, from 900 Elo, and turn on the Coach. You can change the level before every game.

Do I need to download anything?

No. ChessLounge runs in your browser. Installing it as an app is optional, and so is the Stockfish download.

Can I analyze games I played on Chess.com or Lichess?

Yes. Export the game as a PGN file and load it into ChessLounge's game analysis.
