What is Molecule Road?

Molecule Road is a curated chemistry planning game: you are shown a starting material and a target, and you pick one real transformation at a time until you reach the target. Each step reveals the product, an explanation, the reaction type, and a safety note, and the round ends with a route recap.

How is it different from Molecule Mash?

They share the same curated reaction graph. Molecule Mash walks a short branch and asks which product a reaction makes. Molecule Road shows a start and a visible target and asks you to plan the path between them, choosing the moves that lead to the goal.

Are the reactions real?

Yes. Every transformation offered is a familiar, textbook-accurate change with a checkable source, a declared simplification level, and a mass-balanced equation. The moves you can pick are always the genuine transformations of the molecule you hold.

Is every puzzle solvable?

Always. Each target is mined by searching the reaction graph from the starting material, so a valid path is guaranteed to exist before the round is offered, and the game stores one known solution to recap at the end.

Is it available in other languages?

The interface is available in all 25 PlayMemorize languages. Chemical formulas and canonical compound names stay language-neutral, as they are worldwide.
