• Big cubes now show the Premium lock up front. Entering your cube by hand is always free, and 2x2 and 3x3 always solve free - but if solving your 4x4 to 7x7 needs the one-time unlock, you'll see that before you start entering colors, not after.

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.
