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.
