Puzzle games are all about chalenging your mind. They put to the test your ingenuity and knowledge throwing at you a wide variety of puzzles that you will have to solve following certain rules. They can take multiple forms and most of the time they require you to answer questions or to move items in a certain way in order to progress, but there are games that feature quite complicated abstract puzzles that play with your perspective, words or numbers. Problem-solving is at the core of all puzzle games, but its usually accompanies by some sort of storyline or motivation that compels you to solve them under a time limit, taking difficulty to a higher level. Professor Layton, Scribblenauts, and Big Brain Academy offer you different approaches to the genre.
