50 free Silo trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Silo is the Apple TV+ drama about ten thousand people living in a 144-level bunker who have been told for generations that the outside air will kill them. It grew out of Wool, a short story Hugh Howey self-published on Kindle in 2011 and turned down seven-figure offers to keep, and it spent a decade as a stalled Ridley Scott film before Graham Yost rebuilt it as a series with Rebecca Ferguson as the mechanic-turned-sheriff Juliette Nichols. These 50 questions cover the show and the books behind it: Holston and Allison's cleaning, the Pact, Judicial and the raiders, Bernard's IT department, Walker's workshop in the down deep, Silo 17 and the survivor called Solo, the season-three flashbacks to Congressman Keene and Senator Thurman, and the nanobot truth behind the argon. There are production questions too: the Hertfordshire studio where the staircase was built, the production designer credited with the silo, the composer, the Canneseries premiere, and the renewal that set a fourth and final season. Easy questions stick to the main cast; the hard tier asks about Silo 40, Operation Fifty and the print deal Howey signed with Simon & Schuster. Every answer is cited to a page we checked and comes with a one-line explanation. Play it solo or print it for a sci-fi night alongside our Apple TV+ and dystopia quizzes.
