To transfer your game progress progress to a new iPhone or iPad, please follow these steps:

1. Open your device Settings.
2. Scroll down and tap iCloud.
3. Tap iCloud Backup, wait for the page to load, then select your current device.
4. Tap Show All Apps and ensure Jetpack Joyride is enabled for backup.
5. Tap Back, then tap Back Up Now to manually back up your game data to iCloud.
6. Once the backup is complete, sign in with the same iCloud account on your other iOS device.

Notes:
- Ensure both devices are connected to the internet when playing. This allows your progress to sync properly and avoids data loss or overwriting with an older save.
