Basics

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

To solve the challenge follow the 4 steps proposed by the buttons below.

1)	U	Brings 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)	L'	Shifts the cubie Orange-Yellow-Green to another position in order to protect it against the next rotation.
3)	U'	Reverses the 'side effects' of the first move and restore the two cubies Red-Yellow-Green and Yellow-Green to their original positions.
4)	L	Restores the cubie Orange-Yellow-Green to its (final) correct position.
1)	L'	Brings the cubie Orange-Green to its correct position. However, it will also move the cubies Red-Yellow-Green and Yellow-Green from their correct positions.
2)	B	Shifts the cubie Orange-Green to another position in order to protect it against the next rotation.
3)	L	Reverses the side effects of the first move and restore the two cubies Red-Yellow-Green and Yellow-Green to their original positions.
4)	B'	Restores the cubie Orange-Yellow-Green to its (final) correct position.

(Please note that in both cases the rotations follows the same pattern.)

The sequence above is the sledgehammer: the algorithm used in this tutorial.

There are many other possible solutions. The advantages of this approach are:

• It starts with the needed rotation, making it more intuitive to adopt (and easy to remember).
• It is easy to switch between the two natures of an algotithm:
     - 'rotation centric' (set of moves)
     - 'Algorithmic centric' (stand-alone tool)
