LESSON 1
Meet the cube
Three kinds of pieces — centers, edges, corners — and one rule that runs everything: centers never move. A solve is just putting pieces back around them.
- A cube is 26 pieces: 6 centers with 1 sticker, 12 edges with 2, and 8 corners with 3. The pieces move — the stickers never peel between them.
- Centers never move relative to each other. White is always opposite yellow, green opposite blue. They are the fixed map; a solve is putting edges and corners back around them.
- Every turn has an undo: turn it back. That's the safety net under this whole app — you can always walk a mistake backwards.
- Then watch the demo: 6 moves. Big arrows tell you what to turn — the little letters are just name tags.
