Fusion Drop — Merge Your Way to the Periodic Table Fusion Drop is a physics puzzle where every merge is real science. Drop hydrogen atoms into a reactor chamber, match identical elements to fuse them together, and climb the actual stellar fusion ladder — from hydrogen all the way to iron. HOW IT WORKS Aim and drop elements into the reactor. When two matching atoms collide, they fuse into the next element up the chain — just like inside a real star. Keep merging to reach heavier, rarer elements and rack up your score. REAL DANGER, REAL STAKES This isn't a passive puzzle. Watch the Container and Reactor gauges: let the chamber get too crowded, or go too many drops without a fusion, and it's game over. Antimatter particles show up too — collide them with anything and both are annihilated. The longer you survive, the harder it gets. ELEMENT QUEST MODE Work through a series of levels, each with a specific target element to reach. Earn trophies, climb through fusion ranks, and unlock the next stage of the quest map. DISCOVERY JOURNAL Every new element and reaction you uncover gets logged, complete with the real physics behind it — including where in the universe that exact reaction actually happens, from ordinary starlight to the heart of a supernova. WHY YOU'LL LIKE IT - Simple to pick up, genuinely hard to master - A real risk/reward loop, not just endless merging - Built on the actual alpha-capture nucleosynthesis process - No ads, no tracking, no data collection — just the game Fusion Drop respects your privacy: everything stays on your device, nothing is ever sent anywhere. Just you, a reactor core, and the periodic table.
