Tap the small “•••” button in the top corner. You will be asked a short maths question written in words — this keeps small fingers out. Behind it you will find the unlock option, our other games, the privacy policy, and this contact address.
Open the grown-ups page and tap Restore purchases. Purchases are tied to the App Store or Google Play account that bought them, so make sure the device is signed in to that same account. The unlock is a one-time purchase — you never pay twice, and it works on your family's other devices through Family Sharing.
That means the store could not be reached — usually no internet connection, or a temporary App Store outage. Check the connection and try again later. We deliberately disable the button rather than let it fail silently.
There is a speaker button on the play screen. Tap it to mute everything instantly; the setting is remembered next time.
The spoken words follow your device's language. Our games speak English, Spanish, Portuguese, French, German, Italian, Japanese, Korean, Chinese and Russian. Change your device language and the game follows.
Yes — completely. Nothing needs an internet connection except making a purchase.
No, and no. See our privacy policy — we collect nothing at all.
Refunds are handled by the store, not by us: on iOS use reportaproblem.apple.com, and on Android use the Google Play order history. If something went wrong, email us too and we will help.
