Turning the cube with your finger now feels just right: - Swiping is rebuilt: the layer follows your finger and snaps into place when you let go. Release early and it springs back, so accidental touches never count - Every sticker and every direction now responds - press the middle row and the nearest outer row takes the turn - Gentle haptics confirm each grab and each finished turn, like holding a real cube - Tap the little mirror and the cube gracefully swings around to show its three hidden sides - you can keep turning and following hints from back there New: timed challenges! - The app scrambles the cube and the countdown begins. Solve it in time to earn stars, with each level more mixed up than the last - Running out of time never means losing - you get a cheerful pep talk and a big try-again button Sound is more dependable too: - Voice guidance and sound effects are no longer switched off by the side mute switch - Audio comes back on its own after phone calls and alarms - no need to restart the app Fixed on iPad: - On the scanning screen, the back, manual input, and camera switch buttons could sit outside the screen when holding iPad in portrait. They now always stay visible in the corners of the camera view Everything remains completely free.
