Can I play Paper.io 2 offline?

No. Paper.io 2 needs an internet connection to play.

WHAT NEEDS A CONNECTION

Starting a game, your progress being kept safe, events, rewards, and anything involving other players. Wi-Fi and mobile data both work, and what matters is that it is steady rather than fast.

IF THE GAME SAYS YOU ARE OFFLINE AND YOU ARE NOT

1. Check that airplane mode is off
2. Switch between Wi-Fi and mobile data, then back again
3. Close the game completely and open it again
4. If you are on Wi-Fi, try mobile data instead, and the other way round

Large downloads running in the background can also be enough to upset it.
