Pyramid puzzle

A pyramid puzzle is a mechanical puzzle consisting of two or more component pieces which fit together to create a pyramid.

History

Unknown origin. Children of American pioneers played with simple toys such as these.

Two-piece pyramid puzzles: A regular pyramid is not possible in this case. Instead, we can only form a 4 faced tetrahedron pyramid.

To do this, make the square faces face each other and twist one upright to complete the four faced tetrahedronic pyramid.

Four-piece pyramid puzzles: Join the four identical pieces in pairs so that the smallest triangular faces meet. Turn the squares to face each other and bring them together. This will leave a square face on the two resulting pieces. With the square sides of the blocks facing each other, twist one piece upright to complete the pyramid.
