Android device to Android device data transfer
Your game progress is linked to both your Google Play Games account and the specific device you're playing on. So, when you sign in to the same Google Play account on a different device, your progress is automatically synced and transferred to the new device. That means you can pick up right where you left off, even if you switch devices in the middle of a game.
However, it's important to keep in mind that both devices must be connected to the internet at all times. This is because the game progress is stored in the cloud, and if you play offline, the progress on one device might overwrite the progress on the other device.
iOS device to iOS device data transfer
In order to transfer game data from one Apple device to another, simply sign in to the same iCloud account on both devices.
Once iCloud is enabled and available, your game saves will be automatically backed up and stored in the cloud, ensuring that you can access them on any device signed in to your iCloud account. That means you can seamlessly switch between devices without having to worry about losing your hard-earned progress.
However, it's important to note that both devices must be connected to the internet at all times. This is because the game progress is stored in the cloud, and if you play offline, the saves on one device might overwrite the saves on the other device.
