I have posted the 3D Chess (Quadlevel) version, on Itch.IO... See: Quadlevel Itch-IO Link
I'm new to itch.io.. I thank you for helping me being part of this community. My father invented this game before I was born, and I have been promoting it for decades. Now that I've been out of work, I have spent the time, to program a new version. It plays so well, I cannot beat the AI. The rules can be found at the home-page home page with rules My father was inspired by Star Trek, but it has nothing to do with the Star Trek board design.
Pieces retain much of their original power, and its actually easier to force mate then regular chess. Meaning in regular chess, having 2-Knights vs King is called a help-mate situation... But in Quadlevel, having 2Knights and 2Kings vs 2Kings is very winnable.
Click on a piece and it will tell you where it can go, or first watch the AI play the AI...
