Venker Hanayama Cast Tube Puzzle - Level 5 of 6 - Very Difficult - Includes Crux Sticker

I would not rate this 5/6. I "solved" it very quickly. Conversely I have still not even disassembled equa or ufo; and I've had quartet for over a decade and disassembled it fairly easily but have never managed to put it back together!Once solved, tube is trivial to both assemble and reassemble, and the solution is so simple there is not much fun after that, unlike say cylinder, dial or coaster, all of which still have some replay value after you've put them aside and forgotten the precise sequence to solve. Marble doesn't have much replay value either, but it feels much more elegant (both construction and solution) than tube.I give 3 stars because it is well made, a reasonable fidget toy, and not completely trivial to solve.

Way too easy for a level 5. Once you see how it ought to go, you have two options:SPOILER ALERT!!!Either a very gentle touch or two blobs of blue-tak to allow you to turn each end independently!!

Quem o recebeu ainda não o decifrou, logo, faz o que promete. :)
