Hanayama Keyhole Cast Puzzle - Level 4
Hanayama has been manufacturing games and toys for over 80 years. They're internationally known for their mind-bending series of three-dimensional puzzles. Hanayama puzzles are great assembly/disassembly brain teasers that come in a range of difficulty from 1 to 6.
Here is a challenging maze.
At first glance, the two pieces have simple concave and convex angles on their flat surfaces.
However, when the two pieces intertwine, they take the shape of a 3D maze.
You must twist and turn them around.
If you rush without thinking, you will come to a dead end.
Be careful as you may end up going around in circles.
