Introduction:

As anyone who’s spent time in space knows, gravity diminishes once you leave Earth—meaning that when you’re playing Chinese chess, the pieces tend to float off the board, which can be quite frustrating. That’s why I designed this tactical chess set: the pieces stay firmly in place, no matter the zero‑gravity environment (just kidding—sort of!).

Threaded Fastening:

The chess pieces and board are secured using threaded connections—no magnets required! This ensures a rock‑solid hold, making it ideal for use in environments where stability is limited, such as vehicles, ships, aerospace applications, or even spacecraft. Even during intense vibrations or rough handling, the pieces won’t easily come loose. Thanks to this design, the set also offers built‑in features like anti‑tipping protection, preventing players from accidentally “undoing” their moves, and deterring cheating attempts.

Stackable Pieces with Clear Track Record:

Ever struggled with where to put your captured pieces after eating them—and then losing them all over the place? Or worse, forgetting which pieces you’ve already taken out of play?

With its stackable design, you can simply nest one piece atop another, directly on top of your opponent’s pieces. The captured pieces stay securely in place, seamlessly integrated into your own formation—so you can keep track of your victories at a glance. With just a few simple moves, you’ll have five kills locked in your pocket!

Alternatively, you can use the two “Chu River–Han Border” pieces as convenient storage holders—or stack them neatly to the side for easy organization.
