Stacked with educational games based on the colourful big bricks kids love, Lego Duplo World helps children aged 2–5 bolster their creativity along with their vocab, maths and problem-solving skills.

What we love: The app’s curriculum is based on the Head Start Early Learning Outcomes Framework. Tap into the parents’ section (icon in the upper right) to see the learning goals for each activity. There you’ll also find suggestions on how to play along.

Quick tip: Tapping the gift box in the upper left of the home screen opens a free activity where kids puzzle out how to stack virtual Duplo bricks. (It’s satisfying even for adults.) And don’t miss the hidden handwashing activity in the Play House that teaches children the proper steps for keeping their hands clean.

Meet the creator: The designers and developers at Smart Games spent time playing with physical Lego Duplo sets when creating the app. They have more than 50 apps featuring beloved characters on the App Store.
