Stellar Singularity - Merge Celestial Bodies Into a Black Hole
Gravity Well Containment
How To Play
The containment field holds a gravity well. Drop celestial bodies into it and let physics do the rest: when two identical bodies touch, they fuse into the next stage of the evolution cycle. Aim with the mouse or the arrow keys, drop with a click, a tap or the space bar.
- The evolution cycle: stardust › meteoroid › asteroid › comet › moon › planet › gas giant › ringed giant › star › red giant › black hole
- Merge points: every fusion scores the value of the new body, from 3 for a meteoroid up to 66 for a black hole
- Chain reactions: one drop that triggers a cascade of merges earns a growing chain bonus
- Black hole: +100 bonus points on creation - and if two black holes meet, they annihilate in a gravitational wave worth +200
- Containment failure: if a body sits above the dashed line for too long, the well collapses and the run is over
Only the five smallest bodies fall from your dispenser, in random order, but the display always shows what is coming next. The bigger the pile, the more the pressure builds: bodies squeeze, shift and sometimes pop out sideways when a merge suddenly frees up space. Keep the big ones in the corners, think a few drops ahead, and stay below the line.

Why This Game Is Here
In 2021 a small Japanese game about merging fruit in a box quietly appeared, and two years later the whole internet was dropping watermelons. Suika Game belongs to a long line of beautifully simple ideas - Tetris, 2048, Puyo Puyo - where two identical things become one bigger thing, and somehow that is enough to lose an entire evening.
Stellar Singularity is that idea taken to where this website lives: space. Instead of cherries and melons you are handling stardust, comets and dying stars, and instead of a wooden box you get a gravity well containment field rendered on a cyan phosphor screen. The physics are real: bodies roll, stack, squash under pressure and shoot out sideways when the pile shifts - exactly the kind of beautiful chaos that made the original impossible to put down.
The end of the cycle had to be a black hole, of course. When you finally forge one, you will hear it: the sound collapses into a sub-bass rumble, the way 1982 imagined the end of the universe. And if you manage to merge two black holes, you set off a gravitational wave and they vanish from the well entirely. Nobody said astrophysics was tidy.
