Hape: Quadrilla: Double-Sided Spiral Twist

DOUBLE-SIDED SPIRAL TWIST - Get twice the spinning out of your Quadrilla set with this amazing double-sided spiral twist. Both the concave and convex sides feature spiraling tracks, doubling the play potential. When the spiral twist has its concave side up, marbles will run from the arm into the outer ring and rapidly down to the center. With the convex side up, the flow of marbles is reversed. A marble dropped at the center rapidly travels from the center out to the outer ring and the arm. German-engineered design inspired by Da Vinci Circles.
