Lost Boosters

Hi @carmenax and welcome to our adorable Community 😊 The boosters you collect are saved on your device's memory. This way you can reach them even if you are offline. This also means that if you change the device or reinstall the game you will lose all the boosters. Unfortunately, it can happen that you lose them whenever something happens with your phone memory. We don't recommend collecting a lot of boosters, it's better if you just use them while playing. Here are some tips on safeguarding your boosters.
