Place atoms. Match bonds. Build the molecule.

Every atom has a personality: hydrogen wants 1 bond, oxygen wants 2, nitrogen wants 3, and carbon wants 4. Each puzzle
is a real molecule β€” water, methane, ammonia, ethanol, benzene, even amino acids β€” and your job is to drop the right
atom into each empty slot so the bond counts line up perfectly.

Tap an atom from the tray, then tap a spot on the board. Get every slot right, watch the molecule come together with
confetti, and unlock the next level.

πŸ§ͺ 99 HAND-CRAFTED LEVELS OF REAL CHEMISTRY

From simple Hβ‚‚ and water all the way to the hexagonal ring of benzene and the building blocks of life, Valence walks
you through real chemistry one molecule at a time:

β€’ Starters β€” Hβ‚‚, HF, water, ammonia, methane, Oβ‚‚, Nβ‚‚, COβ‚‚
β€’ Halogens & phosphorus β€” fluoromethane, chloroform, phosphine, PCl₃
β€’ Functional groups β€” methanol, formaldehyde, formic acid, acetone, acetic acid
β€’ Hydrocarbons β€” ethyne, ethene, ethane, propane, butane, hexane
β€’ Rings β€” cyclopropane, cyclohexane, oxirane, furan, thiophene, pyrrole
β€’ Aromatics β€” benzene, toluene, phenol, aniline, pyridine
β€’ Biochemistry β€” glycine, alanine, serine, cysteine, lactic acid, glycerol, urea
β€’ …and more, with single, double, and triple bonds rendered just like a real Lewis structure.

🎨 DESIGNED FOR CURIOUS MINDS

β€’ Bouncy, friendly atoms that feel like little characters
β€’ Real bond visuals β€” one, two, or three lines for single, double, triple bonds
β€’ Each level shows the molecule's name, formula, and bond breakdown ("Bonds: 9 single, 3 double" β€” oh, that's
benzene!)
β€’ Per-level best time and "NEW BEST!" celebrations to chase
β€’ Smooth, tap-friendly controls
β€’ Fully offline β€” no account, no login

🧠 EDUCATIONAL WITHOUT BEING PREACHY

Valence sneaks chemistry into your brain through play. After a few levels, you'll start recognizing atoms by their
bond count and seeing the hidden patterns behind real molecules β€” the same patterns chemists use every day. Great for
ages 8 and up. Challenging enough for parents too.
