Common questions

What is free?

Number Builders, Number Trail, Smart Steps, Mistake Detective, Equal Shares, and Fraction Bridge are free in full: six games and 90 stages. An optional one-time purchase unlocks the other 18 games and 270 stages.

Is the full game a subscription?

No. The full-game unlock is a one-time purchase for the current complete package. The store displays the current price and currency before you confirm.

How do I restore a purchase?

Use the same Apple Account or Google Play account used for the original purchase. Connect to the internet, open the parent area, and choose Restore purchases. Restoring access is available independently of the price display. Purchases do not automatically transfer between Apple and Google accounts.

A payment is pending or the full game has not opened

Please do not buy again. Check whether the store is waiting for approval or has completed the payment. In the parent area, retry verification or restore purchases. If it still does not open, contact support with the store, device model, app version, and a short description. Never send a password or card number.

Does progress transfer to a new device?

Activity progress is saved locally. Restoring a purchase restores access, not activity progress. Moving or reinstalling the app may affect local records depending on your device backup settings.

Can the game be used offline?

The activities and included voice recordings work offline. Buying, restoring, and checking purchases require internet access. Previously verified access is retained when a temporary network problem prevents a check.

How do I change the sound?

Open the parent area and choose Settings. Voice, music, sound effects, and supported touch feedback have separate controls.
