- Idea (from the board game "Compounded"): collect atoms, build a molecule
- The card shows a skeleton with empty slots + real bonds (SVG, not AI art)
- Drag an atom from the tray into a slot (finger or mouse) — the right one locks in
- Tap-an-atom-then-tap-a-slot still works, for anyone who prefers it
- A wrong atom = a gentle shake + which element the slot wants, never a buzzer
- Every element has its own soft pastel — told apart by colour AND symbol
- Fill it → reveal the formula + a fun fact + score the points
- ~12 real molecules in lib/molecules.ts; 8 cards a round
- A round-summary of points + the molecules built
- A hint button (glows a slot + bounces the atom it wants)
- A run of mis-taps → a breathing pause; Delphi hosts
- Played on the painted science-lab plate; every panel is frosted glass on the bench
- Complete it and the flat skeleton becomes a glossy 3-D model of that molecule (code-drawn)
- All 14 substances painted (a glass of water, a bowl of salt, a gas ring, the Earth…) and shown on the reveal card
- The lab repainted tall for phones — full screen, nothing cropped off the sides
- Free-build advance level: no skeleton, atoms drift loose and you bond them yourself
- Add richer organic moleculesplanned
✓ = done · ☐ = planned. Every game is built one step at a time like this.
