This puzzle is deceptively simple looking... it only has eight pieces but provides a surprising challenge! It is similar to a 2x2x2 Rubik's cube, but far more challenging. Instead of solving by colour, you have to bring it back to the correct shape.
Since there are two sets of three pieces that are identical, some interesting solving problems can occur that would not on a cubic 2x2x2.
