The photograph on the left is of a cardboard match box 5.2cm wide x 3.5cm long x 1.5cm high.
The outer box is a sleeve and has the game instruction printed in German and French on the back.
The inner cardboard box has a hinged perforated door with a picture of a purple and red pyramid printed on it.
The inner box holds two five sided wooden pieces about 3cm long x 5.1cm wide x 1.5cm high.
This is a "simple" two piece puzzle. It's been around for a long time - the creator is unknown. When put together correctly the two pieces form a three sided equilateral pyramid. In geometric terms this pyramid is really a tetrahedron (a figure with four equal sides).
Although the pyramid has three visible sides which form the point at the top, the base forms the fourth side, as shown in the photograph of the box inside at the left. This tetrahedron has been cut in half to form two identical pieces as shown in the photograph at the right of the puzzle pieces.
The solution to the puzzle is explained in the photograph at the right. There are two steps to solving the puzzle.
First, the square areas of each of the wooden pieces are placed facing each other. Second, one piece is then twisted upright - thus the pyramid is formed.
