Pyraminx: A fairly simple puzzle.   Rubik's Pocket Cube: A good introduction to the concepts of the Cube. 
   Rubik's Cube: Easily the most famous puzzle ever, as well as one of the most-hated. 
   Rubik's Revenge: The sequel to the Rubik's Cube, this one didn't sell as well. It's one of my favorites. A similar puzzle is now available from Meffert's. 
   Professor's Cube: Also known as Rubik's Delusion. This one is a marvel of engineering, and is the most difficult puzzle of its type that I have seen to date. 
   Impossiball: An interesting icosahedral puzzle that flexes as you turn it. I wasn't able to depict its shape for the solution, unfortunately.
