A puzzle that involves figuring out what happened with regard to a certain incident.
Situation puzzles are usually played in a group, with one person hosting the puzzle and the others asking questions which can only be answered with a "yes" or "no" answer. The puzzle is solved when one of the players is able to recite the narrative the host had in mind, in particular explaining whatever aspect of the initial scenario was puzzling.
A man walks into a bar, and asks the bartender for a drink of water. The bartender pulls out a gun, points it at the man, and cocks it. The man pauses, before saying "Thank you" and leaving.
Solution: The man had the hiccups. When he asked the bartender for a drink he was really asking for a cure to hid hiccups. The bartender realizing this instead chooses to scare his hiccups away, making the man thankful of the bartender.
