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 ramp includes a collector holder for three marbles; the third marble opens its doors for the two others stuck inside, sending all three off on their different tracks. There are three courses: the first consists of a collector holder for two marbles and a serpentine track, the second is a seesaw swing 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 device or onto another connected marble track from Ugears.
