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.

Gridlock Chess

If you had a Java-capable browser, you could play Gridlock Chess here.

White makes one move, then each side makes two. You may not check (or promote a pawn which might check) except at the end of your turn. If, at the end of your move, you have three of your own units in any 2x2 area, they all disappear. You may not allow your king to be such a position even on the first of your two moves.
