Welcome to ChesSOS

At ChesSOS you can play turn-based chess (and now Fischer Random) - similar to correspondence chess - playing many games at once over a period of days, weeks or months. To see a game in progress, click here.

Beta Testing
The site is currently in beta-testing and new features are being added day by day. The Announcements forum page (or What's New on the sidebar) lists features which have been recently implemented, as well as recently fixed bugs. Please report any bugs you may find on the Bug Report Page or send an email to support@chessos.com.
