Build the ultimate marble run with Gecko Run! This gravity-defying, vertical system takes classic marble runs to the next level with creative challenges and limitless replayability. The specially designed flexible tracks and residue-free nano-adhesive pads eliminate the need for support structures that traditional marble runs require, allowing kids to build tall, complex, and unique runs on a variety of smooth surfaces with fewer pieces. Build high and across different areas, around corners, and more. Builders can easily reposition their tracks again and again to design all sorts of different marble runs for hours of hands-on, creative play!
