We accept questions about LARPs (live action roleplaying games), as discussed in http://meta.rpg.stackexchange.com/questions/165/are-questions-about-larps-on-topicAre questions about LARPs on topic?.
Escape puzzles would be off topic here, however. Most escape games do not have any roleplaying component (besides a very bare premise of "you must be a patient in this mental hospital" or "you must be a spy trying to ransack this room") - or really rules other than "solve puzzles and get out" - and therefore fall outside the fairly generous bounds of what an RPG is (like board games, computer RPGs, movie-marketing ARGs, etc.).
