Parity, explained
• A new Parity screen on the home page: every big-cube parity case, previewed on a spinning 3D cube so you can spot yours at a glance. Grouped by cube size, with the fix algorithm and an animated walkthrough.

Guided solve at your pace
• Playback speed control (0.5x to 8x) in Guided solve, matching the solution player.

Scanning that fixes itself
• Scanned a face turned the wrong way round? The app now works out the right orientation and carries on, instead of refusing the cube.
• Scanned the same side twice? It says so, and tells you which side to redo.
• Cubes that can't exist are caught instantly, on your device, pointing at the exact stickers to re-check — no more waiting on a solve that was never going to work.
