These cubes have different types of algorithms in which you can solve the cube in numerous amount of ways. Just keep in mind that all algorithms on all different cubes are not the same. There is a specific sequence of moves that are listed in a specific way to solve the cube. You simply just have to follow along that algorithm, and then you will be able to solve the cube or closely solve the cubes within a few move remaining as possible.
Rubiks Cube's are so fun to solve, it can definitely blow your mind if you can outsmart (solve) the cube!
