50 free American Ninja Warrior trivia questions with answers — trivia quiz, new questions added Oct 2026.
American Ninja Warrior turned a cult Japanese import into one of summer television's longest-running competitions. Teachers, firefighters, students and full-time athletes line up for a single attempt at a course most of them will not finish, and the rare runs that go all the way have become part of TV sports history. This quiz covers the whole story: how the show began, the people in the commentary booth, the obstacles that end most runs, the rules that decide who advances, and the competitors whose names every viewer knows. It also takes in the spin-offs, specials and behind-the-scenes details that set the series apart. The questions suit casual viewers and long-time followers alike. Each answer comes with a short explanation, so even a wrong guess leaves you with a new story to tell during the next episode.
