Free-form 4x4x4 Chess
by L. Lynn Smith

Special Thanks to V.R. Parton for the inspiration of these rules.


Equipment:

1  4x4x4 playing field
1  set of standard Chessmen

Play begins with an empty field.  Each player in turn introduces their
King to the field upon a vacant cell.  Neither King may attack the other.
Then each player in turn may do one of the following:  introduce a new
piece to the field or move a piece in the field.

All pieces are introduced on to vacant cells, and cannot give immediate
check to the opponent King.

Pieces move according to their classic 3D movement, Pawns are replaced with
Unicorns.

	UNICORN slides triagonal.
	ROOK slides orthogonal.
	BISHOP slides diagonal.
	KNIGHT leaps one orthogonal then one forward diagonal.
	QUEEN slides orthogonal, diagonal or triagonal.
	KING steps orthogonal, diagonal or triagonal.

The game is won by check-mating the opponent King.

There is no form of promotion during this game.  Players might opt to allow
captured pieces to become the property of the attacking player.  This would
necessitate the use of an additional set of Chessmen to trade the captives
for the appropriate color.
