3D Game Board

This is actually four games in one:

Four Straight - 3-D Tic-Toe variant for up to 4 people. Indicates no tie ever on record ;-)

Triple Check: a 3-D checkers variant. For 2 players.

Space Pirate: A 3-D chase game - evidently similar to farmer and the Pig. For 2 players.

Space Chess: This really is the rules only as it states in the rules that the chess pieces are not included.

The board consists of 4 clear plastic shelves of 4 levels. There are marbles that sit in holes of these shelves in 4 colors.

Quite hard to find.
