Ernö Rubik’s Cube is possible one of the most well-known puzzles of recent years. Almost exactly a century after the 15-puzzle craze of 1880, Rubik’s Cube set off its own craze from 1980 onwards. It’s a fantastically great puzzle (it actually was the puzzle that got me into the hobby of collection, solving and designing puzzles), and now it has come to the iPhone as well. However, it might just as well have passed this opportunity. The iPhone is not the right place for a Rubik’s Cube.
