Inviting The World To Play

The Global Cardboard Challenge began in 2012, following the overwhelming success of the short film, 'Caine's Arcade'. In 2017, we hope to surpass 1 million child participants!


Inspired by the short film, ‘Caine’s Arcade,’ the Global Cardboard Challenge is an annual event presented by the Imagination Foundation that celebrates child creativity and the role communities can play in fostering it. This September, kids of all ages are invited to build anything they can dream up using cardboard, recycled materials and imagination. Then on Saturday, October 7th, 2017, a day that commemorates the flash mob that made Caine's day in the short film, communities come together and play!


Here are a few resources to help you host an awesome Cardboard Challenge.
