Notch - 13 Piece Burr Puzzle
This exquisitely designed Notch Puzzle is a 13 Piece Burr that seems to have no way to break in; the pieces fit seamlessly together with no cracks or openings! Interlocking Burr Puzzles provide a distinctive challenge for the mind, and history has shown many different iterations over the years. These legendary puzzles have been found in Europe and Asia dating back to the 18th century. Burrs usually take on a traditional seed shape, but they might also appear as spheres, stars, and many more! The Notch Puzzle variant contains 13 non-identical pieces (that use 9 different shapes), which the puzzler must intersect to form the end shape.
