Here you can find tutorials usefull for beginning cuber to expert
cuber. The lower the tutorial stand the more complex but at the same
time faster the method gets. So if you are new to the cube start on
the beginning with a beginner method. If you want it a bit faster but
not too difficult pick a lower one.
I see this page as the most usefull page for 2x2 speedsolving there is on the web, since here are (some methods will be) the biggest variety of 2x2 methods with all their own speed.
What you must realize is this: the 2x2 is not a new puzzle with new techniques (only for advanced stuff), it are only the corners of a 3x3 without the edges and centers. So if you can solve 3x3, you can also solve 2x2.
Layer by layer method 0 This method is the one with the fewest formula's (algorithms) to learn, yet it is the slowest you can find on my site. You can get about 15 seconds with it.
Layer by layer method 1 The most used, yet inefficient method. Good for beginners, and those who can already solve 3x3 a beginner way, or Fridrich way. You can get just about sub 10 with it.
Layer by layer method 2 This method makes 1 complete layer, and then does the rest of the cube. Pretty fast stuff though a lot to learn. Average is about 5.75 with it.
Layer by layer method 3 A.K.A. Ortega method. This method is pretty fast. You can average around 5.25 with it.
Guimond method Method developed by Gaetan Guimond, I addapted it a bit to get even faster. You can average just sub-5, so think about times with 4.80. I use this method and have a best average of 4.14 with it.
EG Method This method is developed by Erik Akkersdijk (that's me) and Gunnar Krig from Sweden. It is even faster than Guimond method, though there is a lot to learn.
OFOTA Method A new experimental method developed by myself. Orient one opposite face, the orient both faces, then permutate both faces.
The biggest collection off all 2x2 methods on the web (and the
fastest)
