Check out Atomic Chess, our featured variant for November, 2024.

Since Java is no longer supported in most browsers, our Java applets probably will not run unless you install an extension that will run them. We recommend installing the CheerpJ Applet Runner extension on Edge, Chrome, or another Chromium browser. If your browser still does support Java, and you're not using this extension, make sure this site is listed in your Java exceptions list. You should find this in the Security tab of your Java control panel.

Tandem Chess

If you had a Java-capable browser, you could play Tandem Chess here.
Keys "s"=save "l"=load "b"=back once

Units captured on one board join the reserves on the other board and may be added instead of moving a unit. Here "Tandem Rules" are in effect, and you may NOT place a unit to check or mate the opposing king. Promoted units that are passed revert to pawns. Both games count for the final score.
