Fight across all six faces of a 3D cube.
How to play
The battlefield is the surface of a cube, shown unfolded: six 4x4 faces. White starts on the Bottom face (D), Black on the Top face (U). Moving off any face edge carries a piece onto the adjacent face, turning to follow the surface, exactly as on a real cube (the net shows which edges join: e.g. the left edge of L joins the right edge of B). Rooks, bishops, queens, kings and knights move as usual along the surface. Pawns march outward from their home face and promote to a queen when they reach the enemy home face. Checkmate the enemy king to win.
