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.

Progressive Mutation Chess

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

Mutation chess played progressively. This is the popular way to play Mutation Chess. Remember that a queen move to an empty square, or capturing a queen, is illegal if it gives check. This is Scotch-style progressive chess, so a check ends your turn. You must get out of check on the first move of your series.
