Overview

About this game

Multiplayer 3D chess! While other 3D chess games simply feature 3D graphics, this one actually implements 3D rules.  It is, to the best of the author's knowledge, the only 3D-rules chess game that can be played over the network. Rules are Capture-the-King Raumschach. The original Raumschach (German for "Space Chess") rules were written in 1907, and the game is noted for its playability, setting it apart from gimmicky 3D versions of chess.  This game features publicly discoverable lobbies as well as private lobbies that allow you to play your friends using a lobby code.  Spread out cells allow for a truly cube-shaped board. Glowing move visualizations allow you to see where both you and your opponent's pieces can move maximizing playability in the face of somewhat complex piece movement. Put your brain to the test!

Public lobbies may be sparse until the game picks up momentum.  Find a match on Facebook!
