## What is Gravity Derby?

Experience the thrill of gravity-driven marble racing in this fully offline, physics-based simulation game.
Every race is unique—your marble’s material, starting lane, skills and the track’s shape all influence the final outcome. Select the powerful skills and activate them at the right moment, gain speed, outplay rivals then win the race.

With multiple bevel track layouts, no two runs are ever the same. Slopes, wave platforms, S-curves, spinning wheels, Tesla-style air valves, and other obstacles create unpredictable momentum changes and exciting moments as marbles collide, overtake, and accelerate toward the finish line.

Perfect for players who enjoy physics simulations, strategy, and quick competitions. Simple to pick up, satisfying to master.
