The hunt involves ferreting out a variety of answers and physical objects based on a series of clues, sent via text messages to players' mobile devices.
In order to shorten the learning curve, Facebook is working on a way to better educate users how to use Home through a series of blue instructional text bubbles (affectionately called Blues Clues) that explain Home's features when you first try to access them.
When clues are read by the host they are fed electronically to Watson, which parses the text, formulates hunches and checks all the evidence it can retrieve to test its hunches and then generates its five best answers, assigning each a confidence level before deciding whether to buzz in.
