Building blocks and puzzles are cool! With this app, young children can solve over 200 tasks and games. The levels have been specially developed for children between 2 and 5 years of age. All levels build on one another. Children can directly apply what they have learned and deepen their knowledge through repetition. ▶ SHAPES In a first step, children learn to distinguish simple shapes: triangle, square, circle, ring,... Then it gets harder, as different sizes and trickier shapes are added.
