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.

This is a simple chess variant which was manufactured early in the 1900's. Pawns move one square orthogonally, and can jump a piece of their own color though not to capture. Otherwise pieces move as in normal chess. Win by capturing the opposing king ("the citadel"). I let the program call "Check" and "Mate". Stalemate is a loss for the side unable to move.
