Movement is explained best in relation to a cube. A cube has 6 faces, 12 edges, and 8 corners.
Rook () — moves through faces of a cube. 6 directions. Bishop () — moves through edges of a cube. 12 directions. Unicorn () — moves through corners of a cube. 8 directions. Purely 3-D piece with no 2D equivalent. Queen () — combines all three: Rook + Bishop + Unicorn. 26 directions. King () — 1 step in any of the 26 directions. Knight () — leaps 2 steps through one face, 1 through an orthogonal face. 48 destinations from the center. Pawn () — 1 step forward (rank or level); captures 1 step forward through an edge.
