The
pieces of this puzzle are made of a wooden board with a proportion of 1 : 2,4.
This is the same proportion as in the Phobus puzzle. The pieces of this puzzle
are also sawn slanted. If you look at the design
graph, you can see that two different notches are used for the pieces of
this puzzle. You can find ten different combinations of these notches as shown
in the diagram below. If you make the Sol puzzle for yourself you can choose six
pieces. Three pieces come together at every vertex of this puzzle. A total of
three notches are at every vertex. Since four vertexes are within this puzzle a
total of twelve notches is essential to complete this puzzle. For the design
above the pieces A, B, F, G, I and J are chosen.
