Gecko Run Marble Run Challenge Edition by Thames & Kosmos | Vertical Marble Run w/Flexible Tracks, No-Mess Setup | Challenge Cards for a Head-to-Head Engineering Design Game for Teams or Solo Play

• GAME ON: This Gecko Run Challenge Edition comes with all the parts needed to challenge yourself or others to epic marble run competitions, including 32 challenge cards with suggested designs and engineering tasks to tackle. Who can complete each challenge the fastest? Can you create the fastest run using only specific parts?
• WHAT'S INCLUDED: Comes with enough parts for two kids (or two teams) to build their marble runs simultaneously, including 2 rapid-fire launchers, 2 marble catcher devices, and 32 challenge cards, each with a unique engineering principle to explore and tackle! Can be used independently or with any of the Gecko Run expansion packs.
• INNOVATIVE: Design your own vertical marble runs with this specially designed system of flexible tracks (made from renewable raw materials) that does not require any support structures, allowing you to build higher with fewer pieces.
• INTUITIVE & MESS-FREE: Tracks attach to smooth surfaces with the help of clever nano-adhesive pads that create a strong but temporary bond; the pads are not glue-based and can be quickly and easily repositioned without leaving behind damage or sticky residue.
• OPEN-ENDED & EDUCATIONAL: Combine different configurations and environments for endless possibilities; develop engineering and problem-solving skills and see physics in action.

Product Description Game on! The Gecko Run Challenge Edition includes everything you need to challenge yourself or others to a marble-run-building competition. With 32 challenge cards, two rapid-fire launchers, and enough parts for two kids (or two teams) to build their vertical marble runs at the same time, this set turns Gecko Run into a fun, thrilling engineering game. The open-ended challenges set rules such as using only the specified parts in an allotted amount of time to achieve a stated goal, like the longest run or the fastest run. There are many possible solutions to each challenge, making them excellent for hands-on engineering design activities. A 16-page, illustrated manual guides you through setting up your first runs and teaches you how all the different elements work. Then draw a challenge card and see if you can win the challenge! Use independently or combine with any of the expansion packs. Directions Includes a 16-page illustrated manual and challenge cards for guided use Safety Warning WARNING: Not suitable for children under 3 years.
