How to Play

Choose a difficulty level and select a molecule to build from the dropdown menu.
Select an atom from the Atoms panel, then click on the workbench to place it.
To move atoms, you can drag them after they've been placed.
To create bonds, select a bond type (single, double, or triple), then click on two atoms to connect them.
Each atom has a valency limit that determines how many bonds it can form:
- Hydrogen (H): 1 bond
- Oxygen (O), Sulfur (S): 2 bonds
- Nitrogen (N), Phosphorus (P): 3 bonds
- Carbon (C): 4 bonds
When you think your molecule is complete, click "Check Molecule" to verify.
Use the zoom and rotate controls to get a better view of your molecule.
