- Idea: the one rule of DNA should be something you PLAY, not something you memorise
- The helix, the backbones, the beads and the translucent glass bases are all SVG, not AI art
- Drag a base from the tray into an empty rung (tap-then-tap works too)
- A correct pair paints the real number of hydrogen bonds — two for A·T, three for C·G
- A wrong base simply won't stick, and the game says which one the rung wants — never a buzzer
- Every sequence is real: the ATG start codon, the TTAGGG telomere, the TATA box, the EcoRI/BamHI sites
- An RNA mode too — wherever a T would go, a U goes instead
- The first screen teaches the pairing rule, and a button brings it back mid-game
- A hint button (glows a rung + bounces the right base), and a breathing pause after a run of misses
- Played on the painted lab plate; Delphi hosts
- Add reading codons into amino acids — the next step after transcriptionplanned
✓ = done · ☐ = planned. Every game is built one step at a time like this.
