The Dexter Quiz is a free online quiz that tests your knowledge of the series with 50 questions about Dexter Morgan, the Code of Harry, and Showtime's iconic serial killer drama. Dexter ran for 8 seasons and 96 episodes on Showtime from 2006 to 2013, plus a 2021 revival series.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll revisit key characters from Dexter Morgan to the Trinity Killer, pivotal plot twists across all eight seasons, the Code of Harry and its moral implications, the show's adaptation from Jeff Lindsay's novels, production details including filming locations, and everything about the New Blood revival.
Michael C. Hall plays Dexter Morgan throughout all eight seasons of the original series and the 2021 revival Dexter: New Blood. Hall was previously known for his role as David Fisher in Six Feet Under.
The Code of Harry is a set of rules taught to Dexter by his adoptive father Harry Morgan. The code dictates that Dexter should only kill people who have themselves killed and escaped justice, and that he must never get caught.
In the Dexter: New Blood finale, Dexter is killed by his own son Harrison. After Dexter's true nature is exposed in the small town of Iron Lake, New York, Harrison shoots him to end the cycle of violence, providing a more definitive ending than the controversial original series finale.
