Drop planets, fuse them, grow your own sun
CasualPlanet Fusion hands you a glass jar floating in space and a little ship loaded with planets. Drop them one by one: two identical planets that touch fuse into a bigger world, from a tiny moonlet through ocean worlds and ringed giants all the way to a blazing sun. Plan your chains, keep the jar below the line, and try to make two suns meet in a supernova.
How to play Planet Fusion
- 1Move the ship left or right to aim the planet it holds, then release, click or press Space to drop it.
- 2Two identical planets that touch fuse into the next, bigger planet and score points.
- 3Fusions set off by a single drop form a chain that multiplies the points.
- 4Grow planets from a moonlet up to a sun; two suns that touch explode in a supernova for a huge bonus.
- 5Keep every planet below the dashed line: if one stays above it for 2 seconds, the run ends.

Tips to play better
- Keep your biggest planets together in one corner and line up smaller ones beside them, so each fusion can roll into the next.
- Watch the Next badge: if the following planet matches one near the top, leave it a clear path.
- Never bury a small planet under big ones; it may not meet its twin again for a long time.
- Small planets are light: drop one between two equals to nudge them together.
