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.
