Left Brain, Right Brain - Use Both Hands, Train Both Sides — About this game
Left Brain Right Brain asks you to repeat short touch-screen challenges with different hands. Connect dots, pop balloons, trace shapes or navigate a maze, then compare the game's results for your preferred and less-used hand. The DS is held like a book and turned as instructed so the touch screen suits the hand in use. Begin by setting your preferred hand and trying Hand Exercises before a Balance or Ambidexterity check. Concentrate on clean taps and a steady line before increasing difficulty; the comparison is an in-game performance record.
