It's a bit like cylindrical chess, but even worse. We played several games, and it's fun, but I've regularly put someone into check and not realised. This is a problem. The front rank of pawns may only move forward one square as their first move, but the rear rank may open with a two or three square move. Pieces may wrap around not only the sides of the board, but also off the front and back, so the four corners are all adjacent.
Pawns effectively treat the board as cylindrical since they can only move forwards.
