The Djeco Zig & Go chain reaction game is a wooden construction set with 28 pieces. Children and adults can build a variety of courses that playfully introduce physical principles such as cause and effect. The various elements, such as wooden blocks, a seesaw and ramps, can be flexibly combined. As soon as the first ball rolls, it sets off a chain reaction that runs through the entire course. This wooden set promotes concentration and spatial awareness when planning and precisely placing the individual components.
