Hi there! That’s a great question regarding your Toca Boca World packs. If you delete the app, the game will reset, and you will lose your progress, including any gifts or characters you've created. However, the good news is that you can restore your purchases when you reinstall the game!

Here’s what you can do:

1. Back Up Your Account: Make sure that your game is linked to your Game Center or Apple ID. This should help in recovering your purchases during reinstallation.

2. Delete the App: Go to your iPhone’s home screen, find the Toca Boca World app, and delete it.

3. Reinstall the App: Go to the App Store, search for Toca Boca World, and download it again.

4. Restore Purchases: Open the app, and it should prompt you to restore your previous purchases once you're logged back in with the same account.
