We had one at a camp I went to this summer, only instead of being trapped in a room, we were looking for three folders hidden in the room. I found codes hidden in a book almost right away, but no one listened when I kept saying that I'd found something. A little while later I noticed that there was a Scrabble board with clues on it to look in the book, and by then I was very frustrated that no one was listening to me, so I just put the book next to the board and left. Probably it would have been more fun if I could do it by myself.
