FAQ
Why didn't my duel link open the app?
You need an iOS device with Sudoku Evolved installed. If you have it installed and the link still doesn't open, restart the app, then tap the link again. We're working with Apple's Universal Links, which can take a moment to register after first install.
How do I see my friends?
Sign in with Apple or Google in the app. Friends, duel records, and the friends leaderboard live inside Sudoku Evolved.
Can I play offline?
Yes — the campaign and Time Trials work offline. Online duels and leaderboards need a network connection.
How do I delete my account?
In-app: Settings → Account → Delete account. Or email us — see the delete-account page for details.
