Cuboro · For the wonder-filled years
Around a corner. Through a hidden tunnel. Somewhere they never expected.
Build a path. Let it roll.
See what happens next, together.

The lovely thing about an unfinished afternoon
A few wooden blocks become a winding road. Then a tunnel. Then a question: “What if we put this one here?” With Cuboro, finishing the run is often just the beginning.
For the “watch this” moments
There’s the hush before it rolls. The surprise when it appears.
And another idea before the marble has even stopped.

Move a block. Find a new path. Pull up a chair and follow their idea—around the next corner, through a little tunnel, and somewhere neither of you expected.
Find their first set ↗Surface channels carry the marble around turns. Watch each connection, all the way along.

Yes. These JUNIOR and STANDARD sets are compatible with one another and the standard Cuboro system. Cuboro XL is a separate, larger system.
Build on a hard, level surface. Align the blocks carefully so the channels and tunnel openings meet. Try the route, notice where it stops, then adjust the build. Height and the route through the pieces matter.
