Download the windows version and extract the dice.jar file from the zip archive. Then you can run it on Linux with "java -jar dice.jar", if you have a java runtime environment (e.g. OpenJDK) installed.

The java version named dice.jar is not available anymore. Is there a reason for this?

Nevermind, previously the java version was a separate download, but now it is inside the zip archive of both the Windows and Mac versions.

You can run the game on Linux with "java -jar dice.jar", if you have, e.g. OpenJDK Runtime Environment installed. Since I do not have a Steamdeck, I can't test it, but it should work.
