Synthesized compounds appear here as collectible stones.

Synthesize reactant stones (e.g. 1× CH₄ + 2× O₂), then apply heat to trigger a real reaction.

How to play

1. Synthesize compounds (validated by the built-in registry or PubChem live). They land on your shelf as stones.

2. Gather every reactant in the right amount — e.g. one CH₄ stone + two O₂ stones (synthesize O₂ twice = 3 stones total). The status line under the 🔥 button counts what you still need.

3. 🔥 Heat It Up! The engine finds a real balanced reaction among your stones, consumes the reactants and mints the products — for a big reaction bonus.

Products can react again → cascade combos. Shimmering stones can react now. A heat press with no reaction fizzles (−10).
