You stand before an old Beyoğlu building in Istanbul. You are c urious to get in through the door that has been left ajar to take a look inside. And at the very moment, the door slams behind you. As there is no one arou nd to hear you, you are all on your own. First, you have to keep calm and check around to find something that could help you get out. Who knows, you m ight find the clue you are looking for from the previously read Sherlock Holmes novels, or the brain teasers you have solved. It is to be seen whether you will be able to access the exit by following the clues or not. Certainly, this is not a real life scene, but a real life versi on of the computer games most of us are already familiar with. Apparently, gamers got bored of playing alone by the monitor in the comfort of their sterile ho mes, and rolled up their sleeves to reinvent these virtual worlds in real life. If you are spared from clostrophobia, this might be a perfect brain teaser to discover how gifted you are as a detective and a team member.
