Played within a 4x4x4 cube. Due to the compression of the field, there must be a compression of the mobility of the Queen, Rook, Bishop and Knight.

• The White Pawn steps one orthogonal down, attacks one diagonal down. It promotes upon reaching the lowest level.
  The Black Pawn steps one orthogonal up, attacks one diagonal up. It promotes upon reaching the highest level.
  There are no two-cell moves for the Pawn, therefore En Passant is not necessary.
• The Knight steps triagonal.
• The Rook steps orthogonal.
• The Bishop steps diagonal.
• The Queen steps orthogonal, diagonal or triagonal.
• The King steps orthogonal or diagonal.
• Castling can be accomplished by moving the King over one of the Rooks. The King will take the position of the Rook and the Rook will change one level.
  Any cell between the two pieces must be empty and the two pieces cannot have been previously moved. It is only necessary to relocated the Queen if the player wishes to castle Queen's side. King's side can be castled on the first move.
  The King cannot be under attack, nor any cell which it must translate. The Rook is allowed to move onto an attacked cell.
