Abstract
A marble race game includes a number of different, interconnected marble race toys so that a marble passes from the exit of one to the entrance of another, downstream race toy. All the toys keep the marble moving fast enough along their paths to be visually appealing and yet increase the time it takes to course the toy paths compared with conventional marble race toys. Several different marble race toys are used, including a funnel toy, a zig-zag toy, a J-loop toy, a paddle wheel toy, a serpentine toy and a pin deflect toy.
