Product details

One 336-piece marble-run building set
Small micro blocks, track pieces and rolling balls
Recommended ages 6–12
Assembly required; adult assistance and supervision recommended

Contains small parts and balls. Not suitable for children under 3 years. This is a compact micro-block set; compatibility with larger building-block systems is not guaranteed.

Supplier chemical-exposure warning: The linked listing displays a California Proposition 65 warning for DEHP, with cancer and reproductive-harm risks. Read the supplier warning.

Build a route. Follow the roll.

Connect a short section of track and release a ball. Follow its path together, then decide what to build next.

Let your child set the pace. A grown-up can help with the smaller connections.

Small pieces. A careful building project.

This set uses micro blocks for detailed assembly. Close-up photographs can make the pieces look larger than they are.

Choose it for builders who enjoy working with small parts, and follow the supplied assembly guidance.

Change a turn. Try another route.

Rebuild a section, try a different turn, or take turns choosing the next connection. Test one change at a time and see where the ball travels.

Keep loose parts together between sessions and away from younger children.
