Could you build it?

ChemLab is a chemistry puzzle game where every level is a real molecule.
Drag atoms onto the canvas, connect them with single, double, or triple
bonds, and watch the structure come to life. Get it right, and you've just
built something your body, your kitchen, or your pharmacy actually uses.


WHAT YOU'LL BUILD


Start simple: water, ozone, methane. Then ethanol, vinegar, vitamin C.
Then the hard ones — caffeine, glucose, riboflavin, table salt as ions.
205 molecules across 41 chapters, from your first H–H bond all the way
to a 47-atom vitamin.

Every puzzle is a real molecule, not a textbook simplification.



REAL CHEMISTRY, NOT FAKE CHEMISTRY

Most chemistry games stop at neutral atoms. ChemLab goes further:

• Formal charges — build ozone (O⁻–O⁺=O), nitric acid, nitromethane
• Ionic compounds — calcium carbonate, magnesium oxide, sodium chloride
as the separate ions they actually are
• Hypervalent atoms — sulfate, phosphate, noble gas fluorides
• 3D viewer — rotate any molecule you've built in interactive 3D
• Structure validation — wrong arrangement? You'll know exactly why



HOW IT FEELS

The first level takes 10 seconds. Level 50 takes a few minutes. Level
155 (riboflavin, the yellow vitamin) will take you all afternoon — and
when you finish it, you've just built a 47-atom molecule from scratch.
And that's not the end: the later chapters take you all the way to
estradiol at level 205.

Tap a bond to change it from single to double to triple. Long-press an
atom to set its formal charge. Stuck? The game offers you a hint — and
hints always work, even offline.

later chapters early, choose what fits — weekly, monthly, yearly, or
one-time Lifetime. No subscription is required to enjoy the game.



ChemLab is built by two indie developers who love chemistry and got
frustrated with apps that show you fake molecules. Every structure in
this game is verified against real chemistry — if it's in the game, it
exists in the real world.
