Spindle Box
Inspired by the classic Montessori spindle box. Tap a numbered box to add one spindle at a time, until it holds exactly its own number — box 0 stays empty on purpose.

About this game
Made for toddlers (with a grown-up nearby), inspired by the Montessori spindle box — a classic material for connecting a written number with an actual counted quantity, including the idea that zero means none at all. Ten boxes are labeled 0 through 9; tapping a box adds one spindle from the shared pile, and once a box holds exactly its own number it turns green and locks in. Tap a completed box again to empty it back into the pile if you want to start it over — there's no wrong move, just counting. Fill every box correctly and a new round begins.
