Do you use this jumbling move when scrambling the helicopter/curvy copter? After a few jumbling turns you can make that "regular" turn. The result is 3 petals swaped!

Yes, I use it all the time when solving, so it is perfectly legal.

That's just an unusual commutator that makes use of jumbling to perform a 3-cycle. I used to use something similar to this to move pieces between orbits.

I managed to solve the puzzle jumbled with this move!!! So happy!

The thing is that the jumbling move I used doesn't turn so easyly as a normal jumbling move on the puzzle, so that is the rason I though was not meant to turn!

I'm not sure the other repliers looked closely enough at this :wink:

For the normal Helicopter Cube at least, this puts the puzzle under a bit of strain (one of the white centers is nearly forced out of the puzzle) and *I* would have said this move is NOT legal as it is technically blocked by overhang bandaging. I sadly do not own a Curvy Copter so I cannot confirm that this blocking is present for that puzzle.

Of course, seeing as it is your puzzle, you can do whatever you want :D Would you like it to be legal?

In any case, such a tight move is not necessary to solve a jumbled Helicopter Cube and this particuar maneuver does not introduce any new positions to the jumbling state space. Jumbling sequences exist that perform this same action without straining the puzzle

I have also run into an occasional situation on the Helicopter Cube in a jumbled state where neither of two particular moves can be made because of overhang bandaging but making BOTH moves simultaneously causes the previously overlapping sections to mesh together in a gear fashion and rotate completely to a new position with no strain on the puzzle whatsoever. Is this combo move considered legal? 8-) The more you allow, the exponentially more difficult it is to model this puzzle accurately, and it's already difficult enough!

Peace,
Matt Galla

Allagem, you are right! The puzzle is strained, i have to hold it tight because pieces could pop, because there is some overhang bandaging, but as you say I will continue using it cause it's my own method.

I hope that the pictures are clear enough to show what movement I say, but now I see that is not meant to be turn! ilegal move ftw!
