The Global Cardboard Challenge is an opportunity for kids and their parents to design, build, and play cardboard arcade games. Inspired by nine-year-old Caine Monroy, who created his own cardboard arcade at his father’s used car parts store in east Los Angeles, filmmaker Nirvan Mullick created an 11-minute documentary in 2012 that went viral. The Global Cardboard Challenge was issued to spread the joy of cardboard arcade building to kids all over the world. At the annual ICAT Global Cardboard Challenge event parents and children collaborate to brainstorm, design, build, cut, paint, prototype, test, and play – the entire design process in one half day. The final arcades have sported a rich diversity of games and ingenuity in cardboard engineering.
