How to have the best multiplayer experience?To play with the lowest possible latency, make sure 5G is enabled and join matches hosted in your own country.
Is login required to play multiplayer?Yes, login is required to play multiplayer. Logging in as a guest allows you to play anonymously, but your results won't affect your multiplayer score or appear on the multiplayer and single-player leaderboards. To submit scores to the leaderboards, you must log in with a full (non-guest) account. However, your single-player progress will always be saved, whether you're logged in as a guest, a registered user, or not logged in at all.
How the game progress is backed up?Your game progress, including single-player and multiplayer scores, is automatically backed up to iCloud. This process happens seamlessly in the background. If your smartphone is lost or the game is deleted, your progress will be restored as soon as you reinstall the game. You must be logged in iCloud and have internet connection in order to be able to backup game progress.
