The complete knowledge

National Bestseller

The first new trivia book in more than a decade from Jeopardy! host Ken Jennings—based on his hugely popular online game “Kennections”!

Five trivia questions. Five answers that share a secret theme. What's the “Kennection”?

Since 2012, Jeopardy! champion and host Ken Jennings has created a weekly puzzle—first appearing in Parade, then Mental Floss—involving a series of trivia questions whose answers have something in common. The trivia questions run the gamut of topics—from pop culture (movies, TV, music) to academic knowledge (history, geography, the arts) to lifestyle (food and drink, sports, hobbies). But the trickiest part might be finding the “Kennection” that links all five answers. Many are standard trivia categories (D-Day beaches! Presidential middle names! Santa’s reindeer! Batman villains!), but almost anything goes, so thinking outside the box is just as important as trivia knowledge. What do feet, McDonald’s, fingerprints, and St. Louis have in common? They all have arches. What about Mercury, Chihuahuas, electrons, and Rhode Island? They’re all the smallest of their kind. Columbia, Grease, and “I Ran” (by A Flock of Seagulls)? They’re homophones for nations of the world.

For the first time, the Kennections canon is available in one convenient volume, with hundreds of new and updated quizzes. is the perfect gift for any Jeopardy! fan, trivia buff, or New York Times “Connections” puzzler.
