Get rolling! The Quadrilla Challenger Marble Run from Hape stimulates builders' minds and keeps them engaged and entertained as they create an endless number of marble runs with straight and curved rails, high-velocity funnels, a seesaw, accelerators, blocks, levelers, bases, and 50 marbles.
Quadrilla sets help kids stretch their imaginations and build logical thinking and deductive reasoning muscles as they play. Kids begin to understand that each type of Quadrilla piece performs a specific function, and that the way they are assembled determines the marbles path and momentum.
