Play chess online,
privately.

Time control

Correspondence games are played with a friend. Choose a clock to play the computer.

Time for each move

Play at your own pace. Each move resets your time; we can notify you when it is your turn. Running out of time loses, or draws when your opponent cannot mate.

Online chess, without the noise

One board. Two simple ways to play.

Chessdox is a free browser chess game built for a quick private match. Start immediately, choose your clock and color, and keep the focus on the board.

Play chess online with friends

Create a private room and send one secure invite link. Your friend joins directly in the browser—there is no account, public lobby, or installation.

Create a private game

Play chess against the computer

Choose from four strengths, pick your side, and play a complete legal game. The Chessdox computer runs on the server, so it works on phones, tablets, and desktops.

Challenge the computer

Private by design

Games are shared by a one-time invite instead of a public profile. Moves are validated by the server, and finished games can be downloaded as PGN.
