This year the Game Changer Challenge had a record number of participants, with nearly 3,000 students embarking on a design thinking journey to solve the 2025 wicked problem: Ensure sustainable futures for all.

With nearly 450 video submissions, judges had a very tough task as every team showed great depth in research, creative thinking, and dedication and motivation to driving positive change in our communities. The empathy, collaboration, creativity and critical thinking on display from every student was incredible.
