Yes, of course! To build the same city on multiple devices, you need to link the game to your Facebook or Apple ID to save your progress.

1. Open the game
2. Go to Settings (tap the ⚙️ gear)
3. Tap "Save Progress"
4. Tap the "Sign in via Facebook" or "Sign in via Apple" button.

You can also build your city on Android devices if you use Facebook to save your game progress.
