4 in pyramid
Players: A and B. each with 4 chips. Win who first can make a pyramid (with a triangular base and perpendicular height to the center of the base) with its 4 chips.
Examples of pyramids (there are 24):
The valid pyramids must be based on an equilateral triangle, and the vertex must be perpendicular to the center of the base (straight triangular pyramid)
Examples of Pyramids
Notice how the two pyramids that are in the same row share the base.
The height, in one case, is a vertex and in the other the center of the tetrahedron.
And the base is always an equilateral triangle.
