Common things

How do I play

Read the equation at the top, then swipe with one finger through the fruit that shows the answer. Taps do not count. Three hearts; a wrong fruit or a missed wave costs one. Five correct in a row doubles the score, ten triples it. Runs get gradually faster after the first three waves.

Changing the language

Open Settings from the home screen and tap the Language row. Six languages are available. The first start follows your phone language.

Ads and the consent form

An ad may appear when you leave the results screen, at most once per two finished runs and never before the revive offer. The revive video is optional and only appears when one is ready. In the European Economic Area, the United Kingdom and Switzerland you are shown Google's consent form on first start; Privacy options in Settings reopens it.

My scores disappeared

Scores and settings are kept only on the phone. Deleting the app takes them with it; a device backup made before the deletion is the only way back.

Start fresh

Settings, then Reset progress, then confirm. It clears scores and results; your language and sound settings stay.

What it needs

An iPhone or iPad, or an Android phone or tablet, in portrait. No connection is needed to play; ads need one.
