The Djeco Zig & Go Junior Magic chain reaction game offers a varied construction course based on the cause-and-effect principle. With colorful wooden building components, rolling balls, ramps, and a special vehicle, new chain reactions can be put together again and again. Dominoes with illustrated patterns, guide rails, and surprise elements such as a tunnel and a tire ensure that each ball dynamically passes on its momentum. The playset promotes fine motor skills as well as forward-thinking during construction. In addition, the marble run is compatible with other sets in the series and allows for versatile expansions.
