Mind Twister

Click a thumbnail to see its larger version and description.
Six circles each with eight pieces and one hole.

Anyone who can solve the classic 15-square puzzle can solve this one in under 10 minutes. The parity problem (two pieces swapped or with one tile turned upside down) only appears to happen if you make all tile colours match their face colour and all numbers increase clockwise with down as out from center (but probably not real see next sentence). Image 8 prooves that some versions had a removable pin to be placed in the remaining hole.
Diameter 84 mm
Weight: 134 grams

The puzzle was produced in so many versions under so many names that one entry can't document them all.
Images 9-10 show the canadian version "JC1 Challenge Ball".
The entry "Wisdom Ball - Inspire" contains the rest.
