Tilt. Roll. Solve.
The maze moves with your hand.
Gravelo turns your iPhone into the controller. Tilt to roll a steel ball through handcrafted labyrinths, avoid the drop, and reach the light at the end — one precise, satisfying run at a time.

No joystick, no buttons
Your iPhone is the controller.
Every wall, every drop, every last-second save happens because you moved your hand — not because you tapped a button. Gravelo reads the tilt of your device directly and translates it into momentum on the board.
Every screen
Built to be played, not just looked at.
Five looks at the same idea: real physics, real haptics, and a campaign that keeps getting harder.
01
Tilt to control every move
No virtual joystick, no on-screen buttons. Gravelo reads your device's motion directly, so the ball responds the instant your hand does.
Simple to learn, hard to master
A gentle first level teaches the feel in seconds. From there, momentum, friction, and timing decide who finishes clean and who falls.

32 handcrafted levels
Every maze is hand-designed, not generated — hazards, tight corners, and goal placement all chosen to teach a new trick.
Feel every impact
Every wall clip, every fall, and every goal is backed by real physics and precise haptic feedback — tuned and confirmed on hardware, not just in the simulator.
