While the choice of activities at Brain Metrix may seem a little odd at first, each of the mini games and tests has been designed with a particular aspect of brain training in mind. Featured games include traditional staples like chess and Sudoku, a clone of old gaming favourite Marble Madness and complex number-based 'brain concentration' games. But in addition to the games themselves, the site provides informative explanations for each of the tests, along with historical and scientific data. The site may look a little basic, but the puzzles are genuinely challenging and highly addictive.
