CreaseTots
Fold real paper with a grown-up, one fold at a time. Match two corners, hold them, press the fold flat — and a square becomes a triangle, a cup, a puppy. The screen shows the grown-up the next fold; the child does the folding.
▶ Play it nowBuilt for sittings of about 10 minutes on the screen. That is our design budget, not a measurement.
Meet your mentor
