In season 3, episode 11, we chat with New York Times bestselling author of The Year of Living Biblically, A.J. Jacobs, about his newest book The Puzzler. A.J. is a self-described “human guinea-pig,” immersing himself deeply, even masochistically, into a given topic and chronicling his experiments, whether it’s living by the Bible literally for a year, or thanking everyone involved in the creation of his morning cup of coffee.

An avid crossword solver, A.J. dives down the rabbit hole of puzzles in his latest book, The Puzzler. He goes on a journey to attempt the world’s hardest puzzles, exploring all the varieties including crosswords, puzzle hunts, mazes, jigsaws, and chess problems. Along the way, he tackles fiendish Japanese puzzle boxes, drags his family to Spain to compete in a jigsaw competition, and even plays an escape room with David and Lisa Spira from Room Escape Artist. The Puzzler is also chock full of puzzles, including a hidden, super-challenging but solvable puzzle that will earn the first reader to crack it a $10,000 prize.
A.J. is a delightful guest with an insatiable curiosity about the world. He talks about his adventures through the puzzle universe and shares some amusing insights that he’s learned along the way. A.J. was funny, knowledgeable, and charming. We know you’ll want to read his book after listening to this podcast.
