Central to Cityseekers activity is the 'community mystery challenge' and the organisations and places that help with hiding and giving clues. Supported by the Cityseekers leader the kids solve clues that take the to a 'mystery challenge location' hosted by a local area community group, artist, local business or other representative of the diversity in the area. These groups then lead an activity that build understanding of who they are and what they do by giving the kids a challenge to solve for the day.
