Рекомендовано от 3 лет. Но моя дочь играла до лет 12, и мне взрослой было интерксно.

Marble Run constructor or "Ball Maze" or "Ball Racing." The task is to connect vertical tubes and chutes into a multi-level tower so that the ball rolls down from the top to the bottom through all funnels and spirals without any obstacles. The set includes a large number of colorful parts: chutes, funnels, spirals, and tubes. A child can build an endless number of track variations. It visually demonstrates the laws of physics and gravity. Recommended for ages 3 and up. However, my daughter played with it until she was 12, and I found it interesting as an adult.
