This 70-piece set includes a sky-high hoop, flexi-twist tunnel, and multiple tracks that connect easily, along with five colorful marbles and 65 building pieces. The color-coded blocks and step-by-step guide allow for three different pre-designed builds, or children can design their own structures to develop STEAM skills. The included storage box doubles as a base for constructing custom marble runs, encouraging collaborative play with family and friends. Additional build ideas are available on the VTech Kids website, and the set can be expanded by combining it with other Marble Rush sets (sold separately). Designed for ages 4 and up, no batteries are required.
