48 hours to change the world. Join Jammers in up to 100 cities around the world to work simultaneously for only 48 hours (or less!) and prototype services inspired by a secret global theme… that’s the main message since far more than a decade of events—and we are continuing to explore ways to change the world around and try out a design–based approach to problem solving and creativity.

And play. Seriously. We are adopting a playful mindset for a serious goal: to expand our own knowledge, learn from fellow jammers and develop our design skills. Three times a year.
