Clock (yeah, I solved it on a sim)
Magic (flips only, experimental)
2x2 (3x3 corners)
4x4 almost (I got the idea of centres first by my friend telling me to do centres first, then make edges and solve. The only thing I needed was parity)
5x5 (due to 4x4 knowledge)
Spin Out (Just needed to know these two words: binary twists)
Yeah, that's about it.
3x3 was from Dan Brown, but conversion to Speedsolving saved by cubing life.
