The challenge with the Rubik's cube is that positioning one cubie often disrupt others.

  Click these 4 buttons
  Buttons this set of rotation is a solution for:
1) will bring the cubie Orange-Yellow-Green to its correct position.
However, it will also move the cubies Red-Yellow-Green and Yellow-Green from their correct positions.
2) will shift the cubie Orange-Yellow-Green to another position in order to protect it against the next rotation.
3) will reverse the 'side effects' of the first move and restore the two cubies Red-Yellow-Green and Yellow-Green to their original positions.
4) will restore the cubie Orange-Yellow-Green to its (final) correct position.

Understanding this examples gives you the basic skills to solve the Rubik's cube. In fact, that sequence of rotations is the sledgehammer: the only algorithm used in this tutorial.

There are many other possible solutions. One of the advantages of this approach is that it begins with the rotation we want to perform, making it more intuitive and easier to remember.
