Thread starter #1
I just saw some ridiculously efficient first layers in the 2X2 Example solve thread, but those are not that systematical for starters to find, so I decided to start this thread to help me and a lot of others out there.

There will be 50 2x2 Scrambles below, and please comment below your FL solution on any color you like. If you have time, feel free to do solution on a scramble's all six sides. The solutions will be updated under the scramble inside spoiler tags. Thanks a lot!
