The model features a three-stage lifting mechanism that moves the marbles forward and backward as they climb up to dive into their amusement park adventure. Which marble will roll down which track? Which one will be the first to reach the bottom? The marble step track includes a collector holder for three marbles; the third marble opens its doors for the two others stuck inside, and all three are sent off on their different paths. There are three courses: the first consists of a collector holder for two marbles and a serpentine track, the second is a seesaw in a C-shaped frame, and the third features a funnel or whirlpool. Finally, all marbles pass through the catch platform towards the seesaw lifting device. A toggle switch mechanism sends the marbles either back along the return track towards the three-stage lifting mechanism or to another connected marble track from Ugears.
