The 2x2x2 Magic Cube (or Mini Cube), originally called the Pocket Cube is the two layered version of a Magic Cube. It was invented by Rubik Erno before the ’80 and was patented on March 29, 1983. At first sight it may seem to be simple and small but it requires spatial thinking and logical reasoning to restore. Compact and portable, it can be taken anywhere, serving as a great stress relief toy and educational puzzle.
