Wire the atoms together so every valence is filled and the molecule matches.

How to play
You're given a set of atoms and a target molecule. Connect them with bonds so each atom's valence is satisfied and the structure matches the goal, single, double or triple bonds where they're needed.
Click one atom, then another, to bond them together
Click an existing pair to upgrade its bond order or remove it
Satisfy every atom's valence to complete the molecule
Match the target structure to clear the level
Game modes
Easy, Medium or Hard difficulty for bigger molecules
Daily puzzle or Practice for fresh targets
Controls
Desktop: click two atoms to bond; click a bonded pair to change or remove the bond
Phone & tablet: tap two atoms to bond and tap a pair to adjust it
Tips & strategy
Place the most-bonded atom (often carbon) at the centre and build outward
Count each atom's remaining bonds, leftover valence means it's not done
Use double and triple bonds to satisfy atoms that can't reach enough neighbours
