Premise: A new crop of 12 nerds enters Nerdvana for a chance at winning $100,000 and the opportunity to sit atop the show's coveted Throne of Games. The contestants live together while they face challenges that test their intelligence, ingenuity and pop-culture knowledge. The dozen nerds vying for the third-season title include a NASA engineer, a history teacher who is a ``Jeopardy!'' champion, a neuroscientist who attends conventions in her spare time, a ``My Little Pony'' fan with an extensive Lego collection, and a marine biologist with a ``Star Wars''-themed kitchen and ``Harry Potter''-themed bathroom. Actors Robert Carradine and Curtis Armstrong return as hosts.
