221b Baker Street is a puzzle solving game based around the Sherlock Holmes characters. You can solve cases by yourself or with up to 4 characters. You can choose what character you play as including the characters Holmes and Watson. You move around each area by rolling a dice and walking to buildings to collect clues. It's a bit like Cluedo because once you think you know who is the killer, the person who was murdered and the motive you can go solve it at 221b Baker Street. It's an ok game but unless you write down clues it would be very hard to play.
