Play chess with friends

Create an invitation and share the game link with a friend. Both players confirm they are ready before the online clocks begin. You can also play together on one device.

Play chess against the computer

Choose a difficulty, your colour and a time control. Computer games run locally in your browser and do not affect your online rating.

Stockfish analysis after the game

Review your moves and explore positions with Stockfish after a finished game. Analysis runs on your own device. It is not assistance during a live rated game.

Rated chess and Fair Play

Rated games require an account with a verified private email address. Your chess rating and Fair Play score are public. Opponent availability depends on compatible players being online.

Getting started

Open the game, select a playing mode and choose your time control. Read the help page for accounts, game review and settings.
