Atom Drop

AtomDrop — a chemistry puzzle game where you build real organic molecules to save humanity's last colony.

In the 2200s, a small group of human pioneers escaped Earth during the great wars. Their ship crashed on Zuron, a hostile planet 230 light years away. They survived underground, living off Graconian mushrooms in vast cave labyrinths — but to reclaim the surface, they need to create Genetically Enhanced Beings that can withstand Zuron's brutal conditions.

That's where you come in. As a colony scientist, you formulate the building blocks of life — one molecule at a time. Atoms and functional groups drop into your sci-fi capsule. Drag and snap them together to construct the target compound, from simple methane all the way to complex esters, amides, and anhydrides. Everything follows real chemistry: proper valencies, bond angles, and IUPAC naming.

Features:

• 75 real organic compounds across 17 categories — alkanes, alcohols, ethers, amines, carboxylic acids, and more
• Accurate bond chemistry — pieces only connect where real valence rules allow
• Progressive difficulty — start simple, unlock harder molecules as you go
• Your progress saves between sessions — pick up where you left off
• Combo system and speed bonuses for fast, accurate building
• Fun facts about every molecule you complete

Can you build them all — and give humanity a second chance?
