Q System is a series of cooperative games based on police investigations that can be solved alone or in a group.

Each “Q System” game consists of 32 cards, with each card serving as a clue. Each clue may or may not be relevant to the investigation.
Only common sense, deductive reasoning, and cross-referencing information will help you find the answers: Who is the culprit? What was the motive? How did the culprit go about it?
