4 of us went and chose the Alcatraz room. Before we entered, we were broken up into 2 groups, which was interesting. The puzzles were, let's say, of medium difficulty. We had to ask the game master for help a few times because we were frustrated. Don't forget to bring spare pants because there is a water-ish section. We felt a tremendous sense of accomplishment as we finished below the 1 hr limit. Looking forward to trying out other puzzle rooms with my friends.
