LESSON 12
Build your own algorithm
Every move in this app is setup, spin, undo. Here is the recipe itself — you'll build a corner cycle from scratch instead of borrowing one.
- 8 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.
