How it works
A box of things and three empty shelves. Put everything away, any way you like. There is no right arrangement.
Tap a thing, then tap a shelf, or drag it there. Things can move again once they're placed. When the box is empty the shelves glow a little, and that's it. Nothing is scored, nothing is wrong. Tidying with no rules is the point: your eyes get order, your hands get something to do, and nobody is checking.
