I believe Cast Cylinder is the 61st Cast puzzle in Hanayama‘s collection. It was designed by one of the world’s foremost puzzle designers, Vesa Timonen of Finland. He has designed many puzzles as well as several in Hanayama’s Cast collection. Anyone who is familiar with this collection will probably be familiar with Cast Loop, which is arguably the most exquisite one in the collection; and It is also one of his designs. It too, is such a magnificent design that if laying around, one would collection. Anyone it was a puzzle. Then, once they realize that it is a puzzle they are amazed. It could even be worn as a piece of jewelry.
Vesa Timonen is renowned for his elegant and deceptively simple (read but difficult) puzzle designs. He has won a number of awards at the International Puzzle Design Competition. His amazing puzzles are beautiful in design, but should not be under estimated as to their difficulty.
Now, with his Cast Cylinder, he has once again come up with an elegant and challenging puzzle. Hanayama rate its Difficulty as 4 out of 6;while PuzzleMaster rate it 8 out of 10.If anything, I would suggest that it is at least that difficult. It is not a puzzle a novice would likely quickly solve, but would give a seasoned puzzler an AG! moment when solved. Most would think that a safe cracker would have to be highly experienced to solve a combination lock, and some of the same skills, or at least a similar approach is in order for anyone who expects to open up the cylinder.
Like all, Hanayama Cast puzzles, the quality of materials and craftsmanship is superb. Being rather small, about 1 1/4 X 1 1/4 inches, it will fit nicely in one’s pocket and be readily available to create instant interest in any gathering of puzzlers regardless of their solving skills.
So you’ve solved…now put it back together!!
