Here's how to save and restore your progress on Google Play:

1. Install the Google Play Games app.
2. Upon launching Google Play Games, you will be prompted to enter your Google account details.
3. Enter the correct details for your Google account.
4. Launch the game and check the settings in the Account menu.
5. If the Connect button is lit up in the game settings, this means your Google Play account is not connected. Tap on it to connect your Google Play account.
6. Don't decline or close the pop-up with the offer to connect your Google Play account when the game asks about it.

Please bear in mind that:
We don't store your game progress and therefore cannot restore it.
There is no way to save or select two or more accounts in our game.
You can only save and restore your progress in this game via your Google Play account.

If your progress was not restored when you connected your Google Play account, it means that it was previously saved only on your device and is now lost.
