Players who sign up for a medical examination arrive at the lab, but despite arriving at the scheduled time, there is nothing left in the lab. Suddenly, they realize that something is wrong – steam begins to seep from a tube, and all the patients lose consciousness. When the players wake up, they find that the door is locked and there is no other way out. It seems that only a notebook and a mysterious rotating code picker can provide them with some clues on how to escape this lab. "Secret Lab" is part of a series of the most popular and best-selling escape room games. Players of Secret Laboratory work as a team and use their creativity and deductive skills to decode, solve puzzles, collect objects, and gradually earn their freedom.
