Common questions
How do I get an extra hint or an extra life?
A few placements in the app let you watch a short, optional ad to unlock one. It's never required, and it never interrupts a puzzle you're already solving.
Does Sudoku Glow show ads between every puzzle?
No. Ads only ever appear if you choose to watch one for a bonus — they're never forced between games.
Can I change the app's language manually?
Sudoku Glow follows your device's language automatically. Switching your iPhone's system language switches the app to match.
I think I found a bug — what should I send?
Email us with your device model, your iOS version, and the exact steps that led to it. A screenshot helps more than a description alone.
