A nice puzzle called WindMill at Puzzle.com designed by Oskar van Deventer.
The objective of WindMill is to scramble the disks and then try to get them sorted again by tilting the windmill left or right.
Only downside of this puzzle online is that it takes quite long to scramble. But it is still a nice game, also for children. Happy Puzzling!
