With the HABA tumbling blocks, little building block fans can "be amazed by the building blocks". With a total of 263 natural and colorful blocks made of beautiful beech wood, a seemingly endless colorful chain of building blocks can be formed. It goes up and down stairs and through a bell gate. If one block falls, all the blocks fall over one after the other thanks to the domino effect. This chain reaction is fascinating to watch, because the blocks even fall uphill. The whole thing is even more fun with the 30 animal dominoes: mouse, frog, penguin, bear, cat and dog are also fun to tumble over one another with the blocks. When playing with the tumbling blocks, children train their hand-eye coordination, their fine motor skills and learn about physical relationships in a playful way.
