Bottled Star: Fusion Game
Hold a star in a bottle.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
A fusion game of sealed stars. Fuse nuclei, climb to iron, choose your end.
Bottled Star is a fusion game where you hold a star in a bottle. Inject nuclei into a sealed chamber, fuse them up the stellar ladder, and decide whether your star ends quietly—or goes out loud.
This is not a match-3 reskin. Every merge follows a stellar fusion ladder inspired by real nucleosynthesis. Hydrogen becomes helium. Helium climbs toward carbon, oxygen, neon, and beyond. Iron is the end of the line—the place where fusion stops paying—and the moment your bottled star has to choose how it dies.
AIM · CHARGE · INJECT
Drag to aim. Hold to charge. Release to fire. Light elements fall hard; heavy ones crowd the center. Same-tier pairs fuse. Helium captures climb the ladder. Miss your timing and the chamber fills until the rim cracks.
FEEL THE PHYSICS
• Dense, tactile collisions in a sealed chamber
• A real fusion ladder (H → He → C → … → Fe), not random candy merges
• Pressure that builds as the rim fills—manage it or crack the bottle
• Endings that remember how your star died
• Short runs you can finish on a break, or long sessions chasing a perfect board
CLASSIC MODE
Build toward iron. Stack careful merges, keep the core alive, and choose your fate. End as a quiet white dwarf, or push iron into iron until the core collapses into a supernova. Chase a personal best, climb the daily and all-time boards, and see how far up the ladder you can peak.
COLLAPSE MODE
Every supernova leaves a neutron-star remnant behind. Remnants sink, pile up, and refuse to fuse. Drive two into each other hard enough—usually with another blast—and you get a kilonova: gold, platinum, and a little room to breathe. Score by kilonovas first, efficiency second. When you’ve banked enough, let it go quiet and lock your result.
CHALLENGE PACKS
Hand-crafted puzzles with shot budgets, goals, and tight constraints. Unlock packs one at a time, or grab all three at a bundle price. Perfect when you want a clear objective instead of an endless board—par shots, fusion targets, and levels that punish careless injects.
STRATEGY WITHOUT A TEXTBOOK
Learn by feel. Watch mass settle. Leave space for the next inject. Decide when a supernova is worth the wreckage, and when a quiet end is the smarter play. Collapse players will start counting remnants the way Classic players watch the iron core.
WHY PLAY
• Experience the thrill of stellar creation in your hands
• Master cosmic collapse without lectures or menus in the way
• Compete on Classic and Collapse leaderboards with a display name you choose
• Unlock optional Challenge packs when you want crafted puzzles
• Play physics that works offline, with optional cloud scores when you’re connected
TIPS FOR NEW PLAYERS
Start Classic to learn the feel of the chamber. Watch how light nuclei race to the rim and heavies settle near the core. Your first supernova will feel chaotic—that is the point. Collapse unlocks a second score language once you understand remnants. Challenge packs wait when you want a puzzle with a finish line.
Physicists call a fusion reactor “a star in a bottle.” Here, you hold it.
