2-Look OLL
For 2-look OLL, you only need to know 10 algorithms. Some of them you should already know if you used Layer by Layer, and others are very simple.
1st Algorithm
The four edges on top can be in any one of these positions, pay no attention to the corners. Hover to see the case name and algorithm.
Second Algorithm
Once you have the cross on top, you have to orient the the corners. There are eight cases for this. After this step, you can go onto PLL. Hover over the image to see the name and algorithm.
