I have spent the last 3 nites trying to figure out how to solve the 4x4 rubik cube that Mei Fan has brought back from Taiwan. I refused to look at any instructions or video. I want to figure out the solution by myself. I have done that for my 3x3. I believe I can do it for 4x4 as well.
So far I am able to resolve the 4x4 a few times. I must admit that there are still some combinations that I cannot resolve for the time being. I am slowly figuring out.
