Mastermind Toys Eva-Blöcke-Set 37 Teile

The varying sizes keep my daughter engaged for way longer than I expected, and the soft foam is perfect for indoor play. She's already figured out how to balance the big triangle on top of the square blocks.

My three-year-old has been stacking these soft blocks for hours and the different shapes mean she's already figuring out which bases make the tallest tower. The 37 pieces give just enough variety without being overwhelming to clean up.

I was pleasantly surprised by how sturdy these foam blocks are—my toddler has knocked over her creations dozens of times, and nothing has dented. The bright colors keep her focused, though I wish the set included a few more of the smaller blocks for detailed towers.
