Get closer to the Quadrilla action with this 44 piece with three gutters that make your marbles race around the outside of the colored blocks on their way to the bottom.
Their design 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.
