Hosts Robert Carradine and Curtis Armstrong will return and also serve as executive producers.
During the competition, the contestants face challenges that test their intellect, ingenuity, skills and pop-culture prowess, with one winning the $100,000 prize.
The second season was executive produced by Ben Silverman and Chris Grant of Electus and Craig Armstrong, Rick Ringbakk and Charles Wachter of 5X5 Media, as well as Carradine and Armstrong.
“King of the Nerds” completed its second season this past March, averaging 1.5 million viewers and more than 1 million adults in the 18-49 demo.
“‘King of the Nerds’ demonstrates the power of nerd culture by drawing not only a fervent fan base but also the youngest audience of any current TBS original,” said Michael Wright, president, head of programming for TBS, TNT and TCM.
The eight ordered episodes are scheduled to air in early 2015.
