Cubic Chess is a chess variant invented by Vladimír Pribylinec beginning with an early version (named Echos) in 1977. The game substitutes cubes for the chess pieces, where the four faces of each cube display a different chess piece (pawn, knight, bishop and rook), two blank are orientated to the players. The symbol of king and queen are only on one side of the cube. This provides an efficient means (rotating the cube on a square) to change a piece's type.

The game begins like standard chess, with a normal 8x8 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 - in to off-board "stock".
• For his turn, a player may either:
  • make a normal chess move using one of the pieces already on the board; or
  • rotate any pawn uppermost his cube to 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).
