Mystery in London: On the Trail of Jack the Ripper is an adventure-puzzle casual game developed by Big Fish Studios, and distributed by Big Fish Games. It is actually a continuation of the Travelogue 360 series, also by Big Fish Studios, wherein the screen can go 360 degrees in searching.
In Mystery in London: On the Trail of Jack the Ripper, you find yourself in London taking on the role of a collector of old books, photographs, and paintings. During your time in London, you find a copy of Dr. Jekyll and Mr. Hyde. There lies a note signed "JR." that begins your quest to identify Jack the Ripper. The rest of the game revolves around you traveling throughout London searching for clues to put an end to this unsolved mystery.
Mystery in London: On the Trail of Jack the Ripper features hidden object game play similar to other Big Fish Games releases such as Mystery Case Files and Hidden Expedition. In this type of game play, a player must locate a list of objects which are hidden among many other objects on the computer screen. Once a player has located all the listed hidden objects, they progress on to the next area of game play. In case a player is unable to find a required object, many hidden object games offer a finite number of hints.
