ChemPour: Reaction Lab

Atoms react on contact and form real compounds — H2O, CO2, HCl. 300 levels, each machine-verified with a proven minimum move count.

Real chemistry does the sorting. You do the thinking.

ChemPour is a chemistry puzzle: the flasks hold loose atoms of real elements — H, O, C, Cl, Na and more — and the instant a real compound's ingredients touch, they react on their own. H meets Cl and hydrogen chloride forms before your eyes, with its real formula. Every level hands you real target compounds (H2O2, CO2, HCl...) and your job is to engineer the contact that builds them, pour by pour.

That one rule changes everything. You are not just sorting colors — you are arranging contact. Plan where atoms will land, because the lab reacts whether you are ready or not.

WHY CHEMPOUR IS DIFFERENT • Real chemistry: H2O, CO2, NaCl and dozens more real compounds, formed by contact • Reactions fire themselves — think ahead, not just one pour ahead • Every level is solvable, and the minimum move count is mathematically proven • A 300-level campaign that grows from first pours to deep multi-reaction plans • Endless mode with fresh, provably solvable boards forever • Unlock new laboratory themes as you progress

RESPECTFUL BY DESIGN • No forced video ads, ever — one small banner, that is all • Lab Assist (a rewarded video) appears only when YOU ask for help after a dead end • One single purchase removes commercial ads permanently • Works fully offline, no account, no sign-up

A puzzle game that respects your brain and your time. Put on your goggles.
