2x2x2 Rubik’s Cube – Pocket Cube
The 2x2x2 Rubik’s Cube (or Mini Cube), originally called the Pocket Cube is the two layered version of a Rubik’s 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 even this puzzle has more than 3,6 million possible permutations.
The puzzle is basically a Rubik’s Cube without center and edge pieces, it has only the 8 corner pieces. If you can solve the classic 3x3x3 then you will be able to unjumble this one too. You can meet two cases what you will never see on the 3x3x3: when two pieces are switched on the last layer. To handle this problem use one of the algorithms.

Pocket Cube mods
There are many variations of the 2x2x2 Rubik’s Cube produced since 1981. Maybe the most well known is the Ice Cube, which has transparent pieces. It turns terrible, but it’s a nice collection piece.
On the picture you can see a 2x2x2 Pyraminx or Pyramorphix, also a nice mod and it’s huge, bigger than a Rubik’s Cube. You have to worry about the orientation of only 4 pieces. Other typical mods are the cartoon figure shaped puzzles, like the one showing Homer Simpson’s head, or about celebrities or Disney characters.
Finally here are some algorithms for nice color patterns. Try them if you have got a 2x2x2 Rubik’s Cube:
- U F2 U2 R2 U
- R2 F2 R2 U2
- R F U’ R2 U F’ R U F2 R2
- U R F2 U R F2 R U F’ R
- U R U’ R2 U’ R’ F’ U F2 R F’
