QiYi OS 2×2 is not a usual 2×2 Rubik’s cube, but it has a little trick that makes solving it interesting even for a professional solver. This cube has basically two layers, that is, if you move the side of the cube, an additional part of the square pops out on the square of some of the cubes. The given cube is considered solved if all the sides of the cube are smooth again and the parts that clicked out are inside. Since it also has magnets, it is very convenient to solve and is an exciting challenge because QiYi has done something new again.
