Abstract: A board game using playing pieces in the shape of regular tetrahedrons, each face being an equilateral triangle with surface markings, such as dots, whose numbers range from one to four, distinguishing it from the other three faces. The fifteen regular tetrahedral playing pieces form three groups of five identical pieces each, each group being a different color. The game also uses a game board consisting of seven separate panels; four triangular and three trapazoidal. Each panel is divided into smaller equilateral triangular areas which are equal in size and shape to the faces of the playing pieces. The panels are connected with a flexible material whereby the game board can be folded into a regular tetrahedral shaped box to serve as the container for the playing pieces.
