This set includes five marbles and 73 building pieces, featuring a musical starting gate, fast tracks, peg maze, launcher, and additional components that connect easily. The color-coded blocks and step-by-step guide allow for constructing three different builds, ranging from beginner to advanced levels, while also encouraging open-ended designs to develop STEM skills. Players can challenge friends and family to design the best course, keeping marbles in motion with dynamic stunts and obstacles. Additional build ideas are available on the VTech Kids website, and the playset can be expanded by combining it with other Marble Rush sets (sold separately). Recognized as a STEAM (Science, Technology, Engineering, Art, and Math) Toy by the Toy Association, this set is designed for ages 4 and up. It requires 2 AA batteries (included for demo purposes only; fresh batteries recommended for regular use).
