Currently browsing: Brainteaser titlesThe subgenre most akin to "pure" puzzle games, brainteasers are designed to test (and often torture) your braincells. The best example of a brainteaser is the famous Rubik's cube. Computer brainteasers usually present the puzzle in a given configuration that the player must manipulate. Being "pure" puzzles, they do not require any reflexes, and most do not have a time constraint.
