This page explains the Ortega Method of solving a 2x2.  This method is for intermediate level solving.

If you are completely new to 2x2 or if you don't understand notation then you can find the beginner tutorial here: How to solve a 2x2 Beginners Method

There are twelve algorithms for this method. You may be familiar with some of the twelve algorithms in this method, as they are also used to solve the 3x3 Rubik’s Cube's final layer.

Step 1: Orientate first layer. 

Solve the white face.  You don't need to have the pieces in the correct position. They should only be orientated correctly. 

Step 2: OLL - Orientate Last Layer

You will now have one of eight cases to orientate the Last layer.  Many of the algorithms are the same as 3x3 OLL Algorithms, but there are shorter algorithms to use as there are no centers or edges.

Hold your cube with the solved face (white) on the bottom and check your top face for the patching pattern.

Step 3: PBL - Permutate Both Layers

You will now have one of five cases to permutate both layers together. Hold your cube with yellow on top and white at the bottom.  Choose from the options below that matched your situation and follow the algorithm to solve the 2x2.
