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.

Turncoat Chess

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

One square is chosen at random after each move. If there is a unit, except a king, on that square, the unit changes sides.

Since this is a computer rather than a physical chess set, units can turn regardless of what is already off the board.

I decided that a unit that turns cannot capture the enemy king immediately afterwards.
