Students who love codes and riddles would love the sixth floor corridor. The walls of the sixth floor corridor are peppered with riddles, word games, number games and all sorts of games that are both mind boggling and mind tingling. Those who manage to solve a riddle are often times rewarded by having their names added onto the wall, either as part of a riddle or a word game. If students are really lucky and manage to solve the most difficult riddles, the wall might reward them with a secret about Hogwarts, in the form of a riddle of course.
