Common questions
My cube says it is not valid
Each of the six colours must appear exactly nine times, and every corner and edge must be a piece that exists on a real cube. Check the highlighted stickers; a single wrong sticker is the usual cause.
How should I hold the cube?
White centre on top and green centre facing you. The step player shows this on every solution.
The scan picked a wrong colour
Use bright, even light and avoid glare. After the scan you can tap any sticker to correct it before solving.
How do I restore my purchase?
Settings, then Restore Purchase, with the Apple ID that bought it.
