Stewart Coffin's Peanut Puzzle, modified by starting from 2.5cm (about 1 inch) diameter spheres. The six pieces are all different. This puzzle assembles into many different shapes, shown in the photos.  Interestingly, in the wood version of this puzzle, the "Triangle" shape is impossible to constuct - but using spheres, it is possible.

The pieces will fit tightly out of the box. I recommend scrubbing them with a toothbrush in soapy water for a perfect fit. One finishing technique is to dye each piece a different color.


IN: 6.299 w x 1.969 d x 0.984 h

This is one of my favorite designs by Stuart Coffin, and this adaptation improves it. It is fun to play with, as it can be solved in several ways. Also, the pieces feel nice and fit together comfortably -- it's not the sort of puzzle that wants to fall apart or that feels fragile when you play with it.

The 3cm version of this puzzle was so nice that I have increased the size of the puzzle pieces to 2.5cm diameter spheres.
