Frequently Asked Questions
I bought "Remove Ads" but I still see advertisements
Open the settings screen in the app and tap Restore Purchases. Make sure you are signed in to the App Store with the same Apple Account you used for the original purchase. If the ads remain after restoring, email us the receipt Apple sent you and we will sort it out.
I changed device — where is my progress?
Progress is stored on the device unless you sign in. If you signed in on your previous device, sign in again with the same account and your puzzles, statistics and difficulty settings will be restored automatically.
How do I turn sound or vibration off?
Open the settings screen from the top of the main screen. Sound effects, music and haptic feedback each have their own switch and take effect immediately.
The hint button asks me to watch an advertisement
Hints in the free version are funded by a rewarded advertisement, which you may always decline — declining simply means the hint is not used. Purchasing Remove Ads removes advertising from the app.
How do I change my advertising or tracking choice?
Tracking permission is controlled by iOS in Settings > Privacy & Security > Tracking. Where the European consent form applies to you, you can reopen it at any time from the app's settings screen.
A puzzle looks wrong or the app crashed
Please email us with a screenshot if you can. Crash reports also reach us automatically, but a description of what you were doing makes the fix much faster.
Deleting Your Data
Deleting the app removes everything stored on your device. If you created an account and would like the cloud copy of your progress deleted as well, email us from the address associated with the account and we will delete the record within 30 days.
