Your game is always saved on your device and there is no need to connect it to Facebook. However, you can additionally save your game by connecting it to Facebook.

Connecting to your Facebook account offers you some extra benefits:
If you want to switch your device (or if you lost your device) you can easily restore your progress.
Play across multiple devices, that way you can play your game via your phone and your tablet, and pick up right where you left off.

To connect your game to your Facebook account, follow these steps:
  1. Open Tintin Match and tap the Cog icon on the top right side of your screen.
  2. Choose 'Save progress online with Facebook' to connect and save your progress.
If you’re playing on an iOS device running iOS 13 or later, you can also connect and save your game to your Apple ID. This allows you to save and sync your game across iOS devices without the need for a Facebook account. If you wish, you can easily connect both your Apple account and your Facebook account.

How can I restore my game?
If you’ve switched to a new mobile device and want to restore your progress on it, simply download the game and follow the aforementioned steps to log into your Facebook account.
The game may ask you which one of two game saves you wish to continue with. To restore your old progress, simply pick the one with the highest level.
