The main model stays frozen. Nudge four numeric beads, a soft prompt, until the model sorts all eight examples without changing a single weight.
Soft prompt: four beads, each a number
Model says circle
Model says square
Nudge a bead.
Drag the beads. Each card shows the shape it should be sorted as.
How to play
- Drag the four beads, or focus one and use the arrow keys.
- Watch the cards jump between Model says circle and Model says square.
- A green solid card is sorted right. Get all eight green within 12 nudges.
- Press the frozen model to try editing its weights. It will not let you.
Turn your phone sideways for a bigger road.
