The Crooked Key’s onsite escape games will likely not be fun alone and many puzzles require two or more people. You will need to book at least two slots for an open game time, so bring a friend if possible. Alternatively, book a timeslot with some spaces already filled. More people is just more fun, and you have a better chance of escaping. The gamemaster will do his/her best to make strangers feel comfortable with each other before the game starts, so have an open mind and embrace the opportunity to meet new people. Key to the City: S.K.I. outdoor game does allow solo play, but there is still a two-ticket minimum charge.
