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.

Keys "s"=save "l"=load "b"=back once

Fergus Duniho invented this game, in which Rooks, Bishops, and Knights may fuse with one another, or be joined by the King. Compound pieces may disassociate.

In this version, I have not allowed a Royal Bishop or Royal Rook to cross over a square under enemy attack. See Fusion Chess B, where this is permitted.

K+R "Dragon King" or "Royal Rook"
K+B "Pope" or "Royal Bishop"
K+N "Equis Rex" or "Royal Knight"
R+N "Marshall"
B+N "Paladin" or "Pegasus"
