Gravelo

Gravelo is a tilt-controlled labyrinth game for iPhone, inspired by classic accelerometer games like HTC Teeter.

Instead of using on-screen controls, you physically tilt your phone to roll a metal ball through a maze, avoid holes, and reach the goal. The game focuses on precise physics, momentum, and haptic feedback that lets you feel collisions with the walls.

There are 64 handcrafted levels across the original campaign and an additional level pack, with increasingly challenging layouts that test your precision and control.

You can compete for better completion times, unlock achievements, and compare your progress through Game Center.

The first 8 levels are free to play. The remaining campaign levels and the additional level pack are available as separate one-time in-app purchases. No ads or subscriptions.
