Check out Grant Acedrex, our featured variant for April, 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.

Zombie Co-Chess

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

In this co-chess variant, hostile units on co-squares are turned into zombies that cannot capture, act as part of a co-pair, check, (if a king) castle, (if a pawn) make an initial double move or promote.

They are restored to normal by finding themselves on a friendly co-square. To save programming space, I made these pawns promote to queens.

Pritchard offers the name "Zombie Chess" for this variant.
