Huzzle Cast Coil – Difficulty Level Hard

Pablo Picasso once said, “Youth knows no age.” No matter your adult age, solve these puzzles as often as you can.

It looks like a box-shaped lump with a hole in it, but it's actually made up of two nearly identical pieces rolled up together. You have to try to take it apart by sliding and rotating the pieces. Although the pieces are angular, they can be rotated in unexpected ways, making their movements quite fascinating. The theme of the puzzle is "loops."
