3D Marble Tracks

Choose a marble and a track, or open Sandbox to start building your own course. Drag to place rails, ramps, curves, and boosters, snapping pieces together to form a smooth route. Test the run instantly to observe physics, then adjust angles and placement to improve flow. Race using simple on-screen steering to maintain momentum, hit checkpoints, and finish fast. Tackle time trials to refine your lines and aim for new personal bests. Save your creations and challenge friends locally by racing on the same track layout and times.
