How to play
Cylinder Chess

The board can be imagined as a cylinder with no horizontal edges on either side.

Introduction

The board can be imagined as being wrapped around a cylinder resulting in a board with no horizontal edges. Therefore, the H file sits next to the A file, and pieces can move freely (and give check) from side of the board to he other.

Starting Position

This variant is played from the standard starting position of Standard Chess.

Moves of the Pieces

All pieces move just as in Standard Chess but with the added ability to traverse around the cylinder. As we play Cylinder Chess on a traditional flat board, not an actual cylinder, we must move the pieces from the A File to the H File as if they were joined.

Pieces can even capture and mate around the cylinder too. Note the pawn capture from H to A. Also that the Rook at C2 can capture both black Pawns at E2 and F2 - one from each direction!

Pieces can not return to their starting position, which would effectively be not moving at all!
