LESSON 11
Rescue a stuck piece
A corner twisted in its slot, or an edge sitting flipped in the middle, looks like a disaster. It isn't: pop the piece out to the top layer and put it in fresh.
- 12 moves to watch. Big arrows tell you what to turn — the little letters are just name tags.
- One piece is starred. It stays lit while it rides every turn. Tap any sticker to follow that piece instead.
- Drag the cube to spin it — any direction, even white-on-the-bottom. When a move plays, it glides back home on its own.
- An X-ray waits underneath — the move broken into setup, the work, and the undo.
