Each set is made up of hollow stacking cubes and a variety of perfectly flat tracks. The paths cut out of each track widen almost imperceptibly from one end to the other, creating an invisible slope that propels the marbles forward
Watching them go is like magic in slow-mo!
Deluxe set includes 2 catchers, 2 toppers, 90 risers, 10 stainless steel marbles, 18 unique tracks, 2 base grids, instruction booklet
Suitable for ages 8+
