Purchases
I bought Remove Ads but the ads are back
Open Settings in the app and tap Restore Purchases. The purchase is tied to your Apple ID, so it restores free of charge on any device signed in to the same account, and after reinstalling. If it still does not restore, check that you are signed in with the same Apple ID you bought it with.
How do I remove the ads?
Open Settings and use the Remove Ads purchase. It is a one‑time payment that permanently disables all advertising, including the optional rewarded videos.
Do I have to watch the ad on the game‑over screen?
No. The Continue button is optional. Watching a short video earns you an extra life or extra time so you can carry on with your score intact — but you can ignore it and tap Play Again or Menu instead. Not every game offers it, because some rounds simply finish rather than ending in a loss.
Playing
The problems are too easy or too hard
Open Settings and choose a Difficulty. Adaptive gets harder as you level up during a run; or pick a fixed level from Easy to Expert to keep every problem the same size.
Can I turn off the sounds or the vibration?
Yes — Settings has separate switches for Sound Effects and Haptics, so you can turn either off on its own.
How do I clear my high scores?
Open Settings and tap Reset High Scores, then confirm. Scores live only on your device, so this cannot be undone — and it does not affect any other device.
Can two people play on one device?
Yes. Duel splits the screen in two and rotates the top half, so both players face each other and answer at the same time.
Privacy & ads
Why did the app ask about tracking?
That is Apple’s App Tracking Transparency prompt. Declining it costs you nothing — the app works identically and you still see ads, just non‑personalised ones. You can change your answer any time in iOS Settings → Privacy & Security → Tracking.
How do I change my advertising consent?
If you are in the EEA, the UK, or Switzerland, open Settings → Privacy Options in the app to change or withdraw your consent at any time.
