Email supportFrequently asked questions
Does Gravelo require an account?
No. Every level and your progress work without creating an account. Signing in to Game Center is optional and only adds achievements and a leaderboard.
How do the controls work?
Tilt your iPhone in the direction you want the ball to roll. Gravelo reads your device's motion sensors directly — there is no on-screen joystick.
The controls feel off — what can I do?
Gravelo behaves like a real wooden labyrinth: the ball stays still only while your device is flat. Hold it level and tilt gently from there. If the ball still creeps on a flat table, the device may be rocking on its camera bump — try it in a case or on your palm.
How many levels are there?
32 handcrafted levels, unlocked in order as you complete each one.
Does Gravelo support Reduce Motion?
Yes. Gravelo respects the system Reduce Motion accessibility setting and adjusts on-screen effects accordingly.
How do I delete my data?
Your progress is stored only on your device. Removing the app removes its local data, subject to the behavior of device backups managed by Apple.
Which devices are supported?
Gravelo requires an iPhone running iOS 18 or later.
