2x2x2 Rubik's Cube - About Tutorial
The 2x2x2 Rubik's Cube (also called as Pocket Cube or Mini Cube) is the two layered version of a Rubik's Cube. This puzzle was invented by Rubik Erno before the 80s and was patented on March 29, 1983. At first sight it may seem to be a simple puzzle but it's good to know that it has more than 3,6 million possible permutations so it's impossible to solve it by just randomly twisting the faces.
The 2x2 cube is an official WCA competition event, the fastest solves being below 1 seconds.
Pocket Cube Mods
The 2x2x2 has inspired many designers and lots of variations and shape mods were produced since 1981 as seen on the picture above.
Starting from the top left a center-shifted 2 color Meffert's Pocket Cube by Justin Eplett which basically is a 2x2 in a 2x2. The Pyramorphix is not a 2x2 Pyraminx but in fact it's a smart mod where you have to worry about the orientation of only 4 pieces. The Kilominx dodecahedron-shaped puzzle is the smaller brother of the Megaminx. On the right a member of the Mad Heads zombie series which proves that any shape can be built on the core of this cube. 2x2 puzzles are available in the shape of cartoon figures, the most common being the Homer Simpson head.
A Ghost Cube and a Mirror Cube in the second row which are probably the most popular shape mods of the NxNxN cubes. Next a non-twisty sliding puzzle, the Inside out 2x2x2 (or Vadász Kocka) which works like a 3D 15-Puzzle. A small Siamese (Triamese) puzzle where three cubes are sharing their corner pieces.
Color Patterns
Try some pretty color patterns if you're tired of just simply solving the cube the traditional way. Try to reach the schemes on the images or invent new ones. Having only four stickers per face the possibilities are limited compared to the Rubik's Cube color patterns. Find the algorithms below if you get stuck.
