A game played inside Qwen3.5-4B. Push one of its 294,912 neurons while it writes and it might start talking about the sea, turn into a doctor, or fall apart. Most do almost nothing. The game is finding the ones that don't.

- Daily. One neuron is hidden. Read what it does to the model, then find it in 15 guesses.
- Dex. Search neurons, scan them, catch the good ones.
- Bounties. Steer the model toward a target, like French or the sea.
- Lab. Push two neurons at once and see if their effects add up.
- Map. Strong neurons laid out by what they do.
