Quadrilla Castle Escape
by Hape
A Hape Quadrilla engineering set built around the suspense of a marble leaving the rotary tower and travelling through transparent stairways.
The return of the castle escape
Some days, it may be a quiet afternoon build. Other days, your little one might add the safety signs and railway signal to make the castle route feel more like a scene. Without anyone really noticing, the same question keeps bringing them back: where will the marble go once it leaves the tower?

Product overview
For children who love the wait-and-see part of play
In family life, the play that keeps coming back is often the play with a little suspense in it. At first, your child may simply want to send the marble from the castle tower and watch where it goes. Soon, they begin leaning in closer, following it through the clear stairways and noticing the path more carefully. Before long, it becomes less about finishing the run and more about setting up that escape again, just to see the journey unfold one more time.
