WP: "Here we go again with yet another "brain training" game on the Nintendo DS full of weird gimmicks and useless statistics. This time, the offender is Left Brain Right Brain 2, and the good news is that as far as pointless training games go, this one is pretty passable. Still, the title's lack of meaningful measurements or denotation of real progress means that its appeal will likely be very limited. Make no mistake, this game is still just a gimmick, albeit one that can at least be mildly entertaining at times.
Every game of this ilk professes to measure some odd facet of the player's intelligence and skill, and Left Brain Right Brain 2 is no different. The game purports to measure and help improve ambidexterity, the ability to use both your dominant and weak hands with equal effectiveness. The way the game measures this is fairly simple and yet extremely reasonable, and in a way, it's amazing no one else has thought of it yet. Holding the DS like a book, the title asks you to play a quick mini-game using your dominant hand. Once you've completed the challenge, you then rotate the screen, put the stylus in the other hand and do the same challenge again in hopes of matching or bettering your dominant hand's score. The game assumes that if your "weak" hand can match your "strong" hand, then congratulations, you are perfectly ambidextrous in that particular facet of life."
