Read full description

Tilt the world. Shape the maze. Find your flow. Marble Machine is a physics-driven ball roller with hundreds of handcrafted levels that combine touch-based puzzles with skillful marble control. Tilt the board, feel the weight of the marble, and reshape the path as the level responds to your actions. Slide and rotate tiles, trigger switches, open doors, and activate portals. The maze is never static - it reacts to both your touch and the rolling marble, creating new possibilities with every decision. Easy to pick up and deeply rewarding to master, Marble Machine is designed for players who enjoy thoughtful puzzles, physical contraptions, and moments of pure flow. โ€ข Physics-driven 3D simulation - Realistic motion, momentum, and gravity create a tactile, physical feel. โ€ข Control the entire playfield via motion sensors - Tilt the board to guide the marble through the maze. โ€ข Rearrange the environment in real time to create new paths and solutions. โ€ข Dynamic interactions and modular contraptions - Switches, doors, portals, and linked elements evolve as you play. โ€ข Hundreds of handcrafted levels across themed level packs - Explore different mechanics, difficulty curves, and play styles. โ€ข Focused, atmospheric visuals and sound design enhance immersion and flow.
