AtomsH has 1 hand, O has 2, N has 3, C has 4. Fill every hand to finish a molecule.
ScoreEvery bond is a pair of shared electrons (+2). Double bonds share 4, triple bonds 6. Finishing a molecule earns a bonus: bigger molecules, bigger bonus.
EarnedPass 400, 900, 1500… points and you earn a power-up you can use whenever you want, from the row under the jar.
ShakeHeat the jar: half-built pieces shake apart and their atoms find new partners. Finished molecules stay together. 3 shakes, and you earn another every 40 drops.
GlowAtoms glowing the same color are already holding hands: a molecule in progress. Bright green sticks = where the atom you're holding can attach.
GasesH₂, O₂ and N₂ drift up and out of the open jar, making room.
ClumpsWater sticks to water (and CO₂ to CO₂, methane to methane, ammonia to ammonia), growing a bigger clump each time, up to 16. They stay separate molecules, just holding on.
ChainsTwo of the same molecule touching link into a longer chain.
FireBurns things into CO₂ and water, or chars sugars into carbon.
LightningSplits water into hydrogen and oxygen.
SunlightCO₂ touching water becomes sugar, like a leaf.
PressSqueezes charcoal into a diamond.
