Visual Description

Is it a string quartet, you will ask. I will say — no, it’s pure metal. Cast Quartet by Hanayama is a Level 6 “Grandmaster” puzzle that packs a punch.

Consisting of 4 pieces it poses a great challenge even for experienced puzzlers. Though, a lot of puzzlers may find the disassembly not very hard — the assembly is really hardcore.

The puzzle is executed in a shiny polished cast metal and has a very good touch. The parts come apart easily, so it is advised to not apply a lot of force to it. It is quite possible to lock the puzzle by pushing parts to hard or even breaking it.

Main Features

There are multiple different ways to solve the puzzle, but what’s more important is that you the reassembly can be completely different. That way, basically, you get 2-in-1 puzzle in your hands.

There are (well, at least) 3 stages that you will need to go through on your way to complete solution with every stage consisting of 3-5 complex and multi-directional moves.

The beauty of this puzzle is that you will have to move 2-3 pieces at the same time, at the right direction and on the proper angle to make it work. Did I say it was hard? Well, it is.

Interesting piece with a great symmetrical touch.
