Sherlock: The Network


Sherlock Holmes has a message for you. He wants you to help him solve his latest case. Using your mobile phone, you must navigate the streets of London discovering clues, solving puzzles and piecing together the case.

Starring Benedict Cumberbatch as Sherlock, Martin Freeman as John, and Mark Gatiss as Mycroft, Sherlock: The Network contains ten new cases to solve with exclusive video, games, puzzles and a leaderboard for top players.


Solve puzzles, unscramble audio recordings, break into computers and assemble images to gain clues. From missing persons and bomb threats to poison and murder, all the cases tie together in unusual ways - and all the threads lead back to 221B Baker Street.

Who is targeting Sherlock and his companions and why? Crack each case to uncover the truth.


The leaderboard collects the scores from all players across the globe to keep track of your timing and performance. The quicker you crack each case, the better your score. Return and re-solve cases, improving your score.

You aren't the only person in The Network - see how you rank compared to other members. Would you be essential to Sherlock's work?


Collect money, essential clues and tools in the street to help you navigate and make you better able to play your part. You can also purchase tools with the money you pick up in the game. These tools let you move faster around the city, make solving puzzles easier and improve your score.

Not everything you find will be relevant, so be diligent. And remember to use your Mind Palace to help solve the case.


Moving through London can be a challenge when time is of the essence. You don't have the luxury of Mycroft's driver or money, so you'll need to pick and choose how you spend your money on transport.

If you don't want to walk you'll need to puzzle your way by taxi or the London Underground to get where Sherlock needs you to go. Quickly unblock traffic jams and plot train routes or fall behind.

Listen carefully and carry out your tasks across the city. Keep in touch and prove your worth.
Become one of the detective's trusted ‘Homeless Network’ across London.
Join forces with the great detective himself to solve cases and save his loved ones.
