This is the nine-hole mini golf course with ramps, banks, and even a wind mill that children construct from thousands of components. Young engineers use the more than 3,100 flexible rods, connectors, panels, and spacers to build their own holes complete with spiral staircases, trap doors, loops, and bridges. The included instruction manual provides detailed step-by-step guidance with pictures for building a pre-tested nine-hole course or young engineers can use their imagination to create any kind of obstacle-laden course they desire. Children even build the two putters, allowing a couple of mini golf architects to compete on the course they just created. Includes nine hole flags, four golf balls, and scorecards. Ages 8 and up.
