# Superflip

Every corner and centre is solved, and **every one of the 12 edges is flipped** in its place.

It's famous because it was the first position proved to need 20 moves, and no position needs more. That's why 20 is called "God's number".

```
U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2
```

> 3D demo, Superflip (20 moves): `U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2`

**Do it twice and you're back to solved.** Flipping every edge twice puts them all back.

> 3D demo, Superflip twice = solved: `U R2 F B R B2 R U2 L B2 R U' D' R2 F R' L B2 U2 F2`

## Common mistakes

- **Expecting a pretty picture.** It looks like a gentle scramble until you see that every edge is just flipped.
