Get started building your own marble runs with this Quadrilla beginner’s set. Drop two marbles into the top and watch as they race down different paths to the bottom. 
 
These marble runs are completely unique for their design.  Their design is inspired by Da Vinci Circles. These Quadrilla Marble runs are unique in that they allow the child to determine how the ball will drop by selecting the relevant block piece and connecting pieces - just like coding. These runs are built horizontally too – the concept being to transfer gravitational potential energy to kinetic energy!
 
Because it is based on a building block system, there are endless combinations that can be created and all sets across the range can be integrated.
