Code Head: X-Treme Culture uses a game-show format, as in You Don't Know Jack, to give players ten and older a chance to test their knowledge on a variety of topics, including history, general knowledge, vocabulary, and spelling. Players create a personalized user icon and then choose from three categories. Contestants may have to answer multiple-choice questions, put items in order, or decide whether two items match for a variety of points. Players can compete solo or against up to three other friends. The game also includes an option for Internet play. ~ Eden Miller, All Game Guide
