Visual Description

Cast UFO is another latest addition to Hanayama. It was invented by Finnish designer Vesa Timonen, the author of such masterpieces as Cast Infinity (Level 6) and simple, but ingenious Cast Ring (Level 1). Master Timonen specializes in puzzles with simple design that mislead you into thinking that the solution is simple.

Interestingly, UFO is a “spin-off” of another Vesa’s “onion” puzzle that he submitted for the 2009 IPP Design Competition. Vesa has created several “food” themed puzzles — another one being “Tangerine” that was serialised by Hanayama as “Globe Ball” and “onion” later become the Cast UFO we all know.

Indeed, the puzzle looks very smooth: the saucer-like shell consists of two parts symmetrically interconnected with each other in the middle and an orb in the center that is embedded in the center of the saucer.

The saucer part has a very nice touch and dark metallic gloss while the orb is shiny and polished. This creates a great contrast and amazing look.

Main Features

The puzzle itself is very cool. Really, I would describe it as a spherical Rubik’s Cube (paradoxical, right?) that you have to solve almost by touch.

The main idea is to get the 4-part sphere out of the saucer part — but how can you even do that? Despite it is a Level 4 puzzle that must be significantly easier then, say, Infinity, but the actual process of solving that puzzle can be very difficult.

The puzzle can be solved in one stage, but it can take you a lot of time to find the right moves and get how the mechanism works, but once you get it can be quite rewarding.

The solution is out there 😉

Great puzzle that is slightly harder than standard Level 4s from Hanayama. Might not be a good idea to start from it if you are moving on from level 3, but if you’d like to practice before level 5 — that puzzle is perfect.

Assembly Tips

  • It is very important to be as consistent and methodological with this kind of puzzles.
    • Try to document all your steps — write down what you before or after you progress further.
  • The reassembly is usually much harder — but not in this case. The reassembly is pretty straightforward. Nevertheless, the reassembly will give you a bigger picture on how the interior mechanism if the puzzle operates.

    If you’d like a bit of history, UFO is a spin-off of Vesa’s “onion” puzzle that he submitted for the 2009 IPP design competition:

    Here, the outer onion shell and the inner onion core are the analogs of the two UFO saucer pieces, while the 4 onion peels are the analogs of the 4 UFO orb pieces.

    Relatedly, Vesa created a second food puzzle “Tangerine” which Hanayama subsequently produced as “Globe Ball” (in plastic as part of a special 2-part “Puzzle Gallery” series).
