Build, race, and expand

Each component is designed for sturdy, kid-friendly assembly, with connectors sized for small hands while still being robust enough for repeated builds. The set supports endless configurations—from straightforward chases to intricate mazes—giving builders room to experiment with sequence, timing, and cause-and-effect. The modular design also makes it easy to swap pieces and try new layouts, sparking creativity and pride in the finished model.

And because Marble Genius play is designed to grow with you, the booster, splitter, expansion elevator, and chain lift can be mixed with other compatible sets. Add a splitter to divide the track, a booster to give marbles an extra push, or lift height with an expansion elevator and chain lift for taller, more dramatic runs. The app continues to provide fresh challenges and content, keeping the experience new over time.

Because the set is part of a broader Marble Genius ecosystem

you can pair it with other boosters and expansion sets to extend play sessions. The companion app adds fresh challenges and content, encouraging repeated, focused play without pressure.
