A more challenging version of the Mini Pins puzzle (also by Jean-Claude Constantin). There are three obstacles to replacing the pieces back into the frame:
1) The usual challenge of a packing puzzle
2) The presence of the square-shaped gap in the middle of the puzzle
3) The metal pins mean that the entire set of pieces, once assembled correctly relative to each other, must be correctly oriented relative to the frame (i.e. each piece has only one correct position - no rotations or mirror solutions)
Each piece only has one hole, so in the empty frame, any piece can fit with any of the pegs.
Made in laser-cut wood and stainless steel by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different laser-cut wood puzzles, as well as metal puzzles and magic tricks.
