🧠 Where your stuff lives

Every tap is saved on your device instantly, so closing the app loses nothing. With a free account, your games, coins, stars and progress also save to your account in the cloud, so the same arcade is waiting on your laptop, your phone, and any new device you sign into. Updates install themselves: every time you open LockIn you're on the newest version automatically.

No account? You can still play - everything stays saved on that one device.
