E-Chess or "Outernet Chess" is an interactive virtual version of standard game of Chess, played on a holographic chessboard. Two players connected remotely over the outernet manipulate the board by pressing on board squares to move the chess pieces.

Chessmaster Hex regularly played chess. When he lived in the Bohemian Junkheap, it was one of his main activities.

Edward played one game of E-Chess against Hex. It was a particularly long game, but Hex won in the end.[1]
