Cuboro

Marble Runs With a Hidden Twist

Cuboro turns a classic building toy into an absorbing puzzle. Each Swiss beechwood cube has pathways inside and out, so kids can create tracks that send marbles rolling, disappearing and reappearing in surprising ways.

What Can I Find in the Cuboro Collection?

Explore starter sets, larger standard sets, expansion elements and replacement marbles for the Cuboro marble-run system. The beautifully made wooden pieces invite builders to experiment, redesign and try one more route, again and again.

How Do I Choose a Cuboro Set?

Starting fresh? A starter set is a lovely introduction to the system and its mix of visible tracks and hidden tunnels. Larger standard sets offer more pieces for bigger builds and trickier routes, making them a great pick for older kids or families ready for a deeper challenge. Expansion sets are best for builders who already have a Cuboro base set and want new ways to keep their creations moving.

A Note for Families

Cuboro contains marbles and is not suitable for children under 3. Always follow age guidance and supervise younger children. A clear floor, a handy basket for marbles and a little patience for the inevitable “where did it roll?” moment can make building time even more fun.
