Drop, merge & make a black hole
A cosmic drop-and-merge puzzle for one thumb. Drop planets into a jar. Two of the same merge into the next one up, from stardust all the way to a black hole. Merge two black holes and you get a supernova.
Four modes plus a daily challenge, leaderboards and achievements, a shop full of planets, jars, backdrops and merge effects, and a soundtrack that builds as the jar fills. Plays offline.









Touch where you want it and the planet snaps to your finger. Let go and it falls in.
Two of the same planet touch and become the next one up the chain.
Merge two black holes and the jar goes supernova, with a score to match.
Stack past the danger line and the soup boils over. That's the game.
Endless. Make a black hole. It ends when the soup boils over.
120 levels with goals: make a given planet, make several of one, or reach a score, all within a drop limit. One to three stars each. Some add a twist: a narrow jar, heavy gravity, or no stardust.
90 seconds and a faster dropper. Planets that overflow pop for a penalty instead of ending the run.
Gravity pulls toward a sun at the centre. Touch anywhere and the dropper swings round the rim to follow your finger.
Chain merges together for a score multiplier, up to ×3.
Rattles the whole jar so stuck planets settle and find their pair.
Removes one planet. Tap the one you regret.
Re-rolls the next planet in the dropper.
Each tool gets one free use per run. After that, refill it with coins or an optional ad.
One try a day with a twist: a narrow jar, heavy gravity, or no stardust. Everyone gets the same planets in the same order.
Come back daily to keep a streak going. Day 30 unlocks the Eclipse set.
No account to make, and no connection needed to play. It plays on a plane.

The music is original and generated in code. It starts sparse and adds layers as the jar fills, so you can hear how much trouble you're in without looking.
Free to play with ads. A single optional purchase, Remove Ads (US$4.99), turns off banners and between-game ads, gives you a free revive every run, and adds 500 coins once. Rewarded ads stay optional either way.
