2x2x2: Ortega /OFOTA (I only know like 25 cases of OFOTA)
3x3x3: Intuitive Fridrich F2L/Intuitive VHF2L + 2L-OLL (35?/57) + Full PLL
4x4x4: My style of centers (one set, opposite set, z or z' rotation, three corresponding 1x2 columns on the left inner-slice with the unsolved one on U slice, rU 2-gen to solve the rest) + Nakajima's method of pairing + The 3x3 method I use
5x5x5: (1x2, 2x2, 2x3, 3x3) block-building centers (one, opposite, z or z', another, adjacent, last two) + Freestyle pairing + The 3x3 method I use
Bigger cubes: Columns (bars) for centers (same order as 5x5) + Freestyle pairing + The 3x3 method I use
3OH: The 3x3 method I use
3FMC: Freestyle triple-X cross + Leave three corners + insertion
Pyraminx: Tips + Solve two adjacent edges + Solve the rest with two commutators
Clock: Match edges in this order: U, R, D or L, the last one + Flip clock and match in this order: U, R, UR, D or L, the other edge, DL, UL and DR
3BLD: M2 + Commutators for corners (visual memo)
