Winner of the Parents’ Choice and Oppenheim Toy Portfolio awards, this is the configurable marble stunt maze that ensures unpredictable results every time. Built for racing two marbles at a time, twenty-seven of the maze’s 108 building block pieces have two possible exits that guarantee a marble’s journey will be different run after run. Six stunt pieces impart further intrigue to each descent—marbles accelerate through two bending tubes, fall down steps within two cascading towers, rebound off of a pivoting trampoline, and finally swirl down a vortex. Includes 30 steel marbles. Ages 6 and up. Largest configuration 30" H x 24" W. (5 1/2 lbs.)
