Most people solve the cube layer by layer. This is a simple way for the human mind to approach the problem, but it is useless for speed cubing.

The basic problem with the layer method is very big. When you finish one layer, you need to break it up in order to continue! You break it, do something, then fix it. Again and again. In a good solution you do something useful all the time. This layer is in the way of the solution, not a part of it. The following tips explains the concept.

Petrus method:

  • Step 1 - Build a 2x2x2 corner
  • Step 2 - Expand to 2x2x3
  • Step 3 - Twist the edges
  • Step 4 - Finish 2 layers
  • Step 5 - Position the corners
  • Step 6 - Twist the corners
  • Step 7 - Position the edges
