Commence Software's Tri-Dimensional Chess is a multi-platform game written in the Java programming language. It runs on the popular operating systems Windows, macOS and Linux, as well as other operating systems that support the Java Standard Runtime Environment (SRE). It is inspired by the game introduced in the original Star Trek television series of the late 1960s. This game is based on Jens Meder's "International Rules for Three-Dimensional Chess," which were created as an extension of the "FIDE Laws of Chess" for conventional chess.

As a life-long student of conventional chess, the author of this software was intrigued by the notion of extending chess into a third dimension. Whereas conventional chess boards are ubiquitous, it is very uncommon to find a physical Tri-Dimensional chess board. This limited access to boards, as well as opponents, makes learning the game challenging. Commence Software's Tri-Dimensional Chess solves this problem by providing a virtual board and opponent.

A Tri-Dimensional Chess board is comprised of three static main boards and four moveable attack boards, as seen in the game available from gate io singapore. The chess pieces move in a conventional manner but can traverse, land and attack on multiple levels.
