7x7
Reduction
Like the 5x5: centres, edges, then the 3x3. The only parity is Edge parity on the last edges.
How to read the moves
You hold the cube facing you. The letter is the face: R right, L left, U up, D down, F front, B back.
A letter alone is a quarter turn clockwise, looking straight at that face. An apostrophe (R′) is a turn the other way, and 2 (R2) is a half turn.
Rw (a wide move) turns the two outer layers at once, 3Rw three. A number alone before a letter (2R, 3R) turns just that one inner layer, counted from that face.
A 7x7 scramble also uses 3Rw, 3Uw…, and Edge parity uses 2R and 3R moves.
- RRight face up
- RwTwo right layers up
- 3RwThree right layers up
- 2ROnly the second layer from the right, up
- 3ROnly the third layer from the right, up
- 3UwThree top layers to the left
Step-by-step method
1. Centres
intuitiveOn each face the 5x5 centre is one colour.

- As on the 5x5: first two opposite ones, then the remaining four. It helps to start with the middle 1x5 strip.
