The App Store lists the game at 3,411,818,496 bytes, or about 3.4 GB. On Android, the Play Store size is not shown here, so leaving at least 100–500 MB of extra headroom for updates and cache is sensible.

The usual causes are not enough storage, a weak or interrupted connection, an incompatible Android or iOS version, or a stalled store session. On Android, clearing the Google Play Store cache can also help.

On Android, open Google Play Store, tap Install, then launch it from the home screen or app drawer. On iPhone or iPad, open the App Store, tap Get, authenticate if needed, then open the app once the download finishes.

The official listing does not spell out a named currency here, so the safest advice is to use only the in-game shop and gameplay rewards shown inside the app.
