Zenoku is classic Sudoku with no ads, ever. Thanks for playing.
My game disappeared. Zenoku autosaves your game after every move. Tap Continue on the home screen to pick up where you left off. Progress is stored on your device, so deleting the app deletes your data.
Leaderboards are empty or won't load. Leaderboards use Apple's Game Center — make sure you're signed in (Settings → Game Center on your iPhone) and connected to the internet.
How do hints work? Hints reveal the correct number for the selected square, but they cost score points, break your streak, and disqualify the Perfect bonus.
What's the Daily Challenge? One puzzle per day, identical for every player worldwide. Difficulty rises through the week. Complete consecutive days to build your streak.
