Cubic chess is a chess variant invented by Vladimír Pribylinec beginning with an early version (named Echos) in 1977.[1][2][3] The game substitutes cubes for the chess pieces, where four of the faces of each cube display a different chess piece (pawn, knight, bishop and rook), the two other faces are blank and are orientated to the players. This provides an efficient means (rotating the cube on a square) to change a piece's type. Kings and queens have unique cubes containing only their symbol, effectively behaving as normal.

The game begins like standard chess, with a normal 8×8 chessboard, and cubes rotated so that uppermost faces reflect the standard chess starting position.

Game rules

Cubic chess follows the normal rules of chess (including castling, check, checkmate, etc.), but with the following special differences:

  • Non-pawn pieces that become captured, are retained by the capturer—unrotated—into off-board "stock".
  • For their turn, a player may either:
    • make a normal chess move using one of the pieces already on the board; or
    • rotate any pawn such that uppermost on the player's cube is any piece type contained in the player's "stock". A corresponding piece in the stock is immediately removed from the game.

Sample game

Note on notation: When a pawn is rotated to display a new piece type, the new piece is written in parentheses, for example: 6...h7(B).
