Traditional paper based mysteries were designed to be collaborative, to encourage high quality exploratory talk and for ideas to be co-constructed by pupils as they 'shared their brains'. They were a strong part of infusing thinking skills into the subject curriculum. Digital Mysteries retain these advantages but add several new dimensions such as encouraging effective collaboration, provision of scaffolding, and support for reflection.

The use of Digital Mysteries is not limited to the existing set of predefined mystery tasks. Digital Mysteries can be used as a general thinking skills collaboration task using student or teacher prepared/collected contents. Instead of selecting a mystery from the library, it is possible to select any suitable folder on the computer and the application will display all the existing text files, images, video and audio files as slips (one slip per file). Students can manipulate these files, group them, and create associations just like a normal mystery and use all the application tools, follow the stages procedure and use the playback (reflection) features. This is a very significant tool for developing information management, planning and metacognitive skills.
