ZZ44 method is a 4x4x4 speedsolving method proposed by Quoc Hung meant to suit users of the ZZ method. It can also be applied to bigger cubes.
It similiar to Hoya but with EOpairing.
The step
- F2C: Two opposite centers (not U/D ones).
- D and B centers.
- Pseudo cross edge
- Place any 2 oriented edges on the BR and BL spots
- Last 2 centers.
- Edge pairing
- Finish by ZZ (EO+Parity OLL, ZZ F2L, COLL, EPLL+Parity PLL.)
The Pseudo Cross
- Pseudo Cross for EOLINE solver :
-1 line edge + Any good edge at DL(or DR) cross positon.
- Pseudo Cross for EOArrow solver:
-1 Line Edge + DL(Or DR) cross edge.
Last Layer
For the last layer, you can use the same COLL algs as on 3x3, as you don't need to worry about orientation parity due to it being solved already.
After COLL, you have EPLL+parity. There are the 4 normal EPLL cases (H-perm, Ua-perm, Ub-perm, Z-perm), plus the additional opposite swap, adjacent swap, Oa, Ob and W permutations.

Do the correct algorithm out of the 9, and you're done!
Pros
- Gives a ZZ finish for a low movecount than Hoya,similar movecount to Yau, with all of the advantages Hoya has.
- Easy look ahead
- Less cube rotations
- The most used moves are Rw, Lw, L, R, U. Very few F, B moves. Resulting higher TPS.
- Better ways to deal with parity. The number of algs used in a solve with double parity is one less than with standard Yau with double parity, and PLL parity recognition is easier due to corners being solved.
- Suited for ZZ solver
Cons
- L2C can be a little hard.
