Building blocks-with a twist! The cool thing about Quadrilla is, kids are building structures to make marbles move, so the key (and satisfaction) involves how to position the holes in the blocks. They must use their noggins!
Add musical accompaniment to their building projects with the Melody Basic Set.
This set is a great accompaniment to other Quadrilla sets but also works great on its own. It has five tones, rails, and blocks, plus two marble trays. The set plays musical tones while the marble runs through the track. A great set for a beginner or a Quadrilla pro!
