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.

If you had a Java-capable browser, you could play Troja here.

Chess Variants

These are simple illustrations rather than strong opponents.

In Troja, which is a commercially-available game, friendly units (except for kings) may stack, and stacks split. Promotion is only to pieces already captured. For this program, if no piece is available, I decided that promotion would not occur at all.
