Curved slides

 

— all slides are called curved, in which the shape of the descent (when viewed from above) differs from a straight one: it can be bent to the side, zigzag, etc. The surface of the descent itself can be both straight and wavy. Curved trajectory provides additional entertainment; in addition, it increases the length of the descent, without affecting the length of the slide as a whole. However such models cost a little more than their classic counterparts.
