Designed for single players, groups of friends, and even teams, the fischertechnik Marble Competition lets you build exciting racetrack models for hours of interactive entertainment! The building kit includes three completely different action-filled models. Once the track is built, the fun really begins with exciting races! Kit highlights include the wide, flexible high-speed tracks and wide 180-degree curves for daring passing maneuvers. The colorful marbles also add a lot of fun, because each player picks a color and then watches and cheers them on through the fast obstacle course. But don’t celebrate too soon – adjustable roadblocks can slow or stop the marbles, keeping the race exciting to the very end. All three models feature different racing modes with various launching devices.
