Gravity Derby vs Orbit Collapse

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. Features Realistic gravity-based physics simulation Multiple textures and marble material types Varied track designs: slopes, wave floors, S-bends, rotating discs, air-valve boosters, and more Offline play with no internet required Fast races perfect for casual sessions Smooth visuals and satisfying sound effects Test your intuition, learn the physics, and become the ultimate marble racing strategist!

Merge planets. Birth black holes. Orbit Collapse is a cosmic twist on the merge-puzzle game you already love — simple to pick up, endlessly satisfying to master. HOW TO PLAY Drop planets into orbit and merge two of the same kind to create the next one up — from drifting Stardust all the way to a collapsing Black Hole. Chain merges together for massive combo bonuses, but watch the danger line: let the board overflow and it's game over. FROM STARDUST TO SUPERNOVA Climb a twelve-tier cosmic ladder — Stardust, Asteroid, Comet, Moon, Mars, Venus, Earth, Jupiter, Saturn, the Sun, Supernova — and finally, a Black Hole. Reach it and it doesn't just vanish: it stays on the board and keeps devouring, growing more powerful the longer it survives. THREE COSMIC POWERS Earn power charges through combos and use them when you need a save (or just want to show off): • Mini Black Hole — devours nearby planets, growing as it feeds • Alien Strike — mark multiple planets and watch them zapped in sequence • Cosmic Shuffle — clears the board and rains it all in fresh A NEW CHALLENGE EVERY DAY The Daily Challenge gives every player on Earth the exact same board — same drops, same meteor showers — all day long. Finish a run to keep your streak alive, and compare your score on a leaderboard built just for that day. CHASE THE LEADERBOARDS Compete on Game Center leaderboards for your all-time best score and the daily board. A DARK, ATMOSPHERIC SOUNDTRACK An original synthesized score sets the mood — sustained analog pads, deep bass, and a driving low-register pulse. Play with the volume up. Orbit Collapse is free to play, with optional ads that never interrupt a run in progress, and a one-time Remove Ads option for players who want it uninterrupted.
