Since our Katamino/Pentomino series got so popular we looked deep into our drawers and found this!
A round 3D wooden 'Chinese' puzzle, also called spherical or ball burr puzzle.
6 pieces forming a wooden 'ball' - take them away one by one to solve the puzzle.
The pieces have notches of different depths and widths and they can only be matched only in one way.
But once you find the trick (like with other puzzles) the rest is relatively easy.
Our recommendation with this type of puzzles is that you never use force to solve them!
BTW, Katamino/Pentomino videos that we mentioned are here:
Part 1 (levels 3 to 5):
Part 2 (levels 6 to 9):
