Challenges are large-group collaboration activities in which the community must solve a complex problem through leadership, cooperation, and teamwork.

Challenges form an important component of the Mazemakers program, helping to build leadership skills and strengthen community while providing the opportunity for young people to prepare for a society that requires and values creative thinking. There are usually 2 to 3 Challenges per session. On Challenge days, classes are either shortened or suspended, depending of the level of challenge and the length of time needed to solve it.
