Every Monday and Friday, the site posts a new mystery, followed by the solution the next day. At the end of the story is a menu asking who the reader thinks committed the crime. Users are also asked to highlight up to four statements in each story, indicating if they either Exonerate or Incriminate one of story’s characters. To help spice things up, the site keeps score for every member based on their accuracy, with the most ingenious detectives featured on the site’s leaderboard.
