Post each shape into the hole that matches it — circle, square, triangle and more.
Shapes are the vocabulary a child needs before anything geometric makes sense, and it's the one thing no other game here teaches. Every shape is drawn in a single flat colour on purpose: if the circle were red and the square blue, a child could win on colour alone and never look at the outline. Two holes to start, up to five — and at the last level the holes are turned, so the shape can't be matched by orientation either, which is early mental rotation.
