[Help Thread] Megaminx Discussion

This is not a super specific question so I'l assuming you mean can two (or more) centres swap. The answer is no. Megaminx (alternatively called the Hungarian Supernova) is a face turning puzzles turning on the centre axis. This centre is also set on a screw so it's not like you could even have some sort of freak lock up where the centre pieces swap. Like how a corner or edge could twist or, even more unlikely, two pieces could swap resulting in an impossible permutation.

Personally, I've never had that last example happen but I'd be interested in hearing if that has actually happened to someone.
I have had that last example happen. It was because I gave my cube to my non-cubing friend to scramble it, and he mixed up the center caps, and I put them back together in the right order but offset in inspection, and that caused me to have 2 adjacent edges swapped in an impossible PLL.
