The 213-piece maxi construction set is ideal for all beginners who want to dive right into building large marble runs. It provides all the necessary building blocks for creative constructions of dynamic and spectacular marble runs: a large base plate, numerous construction blocks, many different track elements including the new left and right slides, and marbles. An instruction book illustrates four different assembly options. The construction set is packaged in a high-quality case with sorting compartments. This set continuously creates new possibilities for designing tracks and developing individual variations. With the modular and compatible marble run, where nothing wobbles or shifts, spatial imagination and basic physical laws are conveyed. Whether with or without instructions, the colorful setup trains adherence to sequences, stimulates working memory, and develops analytical thinking skills.
