Sledgehammer (definitions)

The 'Sledgehammer' is the little brother of the much more famous 'sexy move'. Is one of the simpliest algorthms and yet is so powerfull to be the only one needed to solve the Rubik's cube.

A 'Sledgehammer' is a set of 4 single-rotations over 2 faces (never opposite faces).

• 1) U The 1st rotation can be clockwise or anti-clockwise.
• 2) F' The 2nd rotation 'follows' the first. (performed in the opposite direction)
• 3) U' The 3rd rotation cancels the first move. (Undo)
• 4) F The 4th rotation cancels the second move. (Undo)

    (This is the most used 'sledgehammer' in the tutorial.)

In certain respects, the 'sledgehammer' acts as a framework that facilitates the rotation we are primarily interested in, effectively containing any related impacts within a specific area known as the 'workbench.'

The 'conventional names' are:

• The 1st move is called the action move (gets the result we want to achieve)
• The 2nd move is called the protection move ('protects' the the first move from the effects of the next moves.)
• The other two moves are roll back (confining the side effect of the first 2 moves)
