Mental Floss has compiled its most challenging questions for its first-ever trivia game—so tough they’re sure to stump even the brainiest trivia whiz.

For more than twenty years, people have come to Mental Floss to answer life’s big questions, uncover fascinating facts, and read stories so interesting they must share them. No wonder Mental Floss reaches more than nineteen million users a month across its website, social media, and YouTube.

Fair warning: These questions won’t be found at the average pub trivia night. The cornerstone of Mental Floss’s content is the odd and unusual nugget of information. While it has been showcased in best-selling calendars and books, it has never appeared in game form until now.

Mental Floss Brain Brawl is a trivia game on steroids, with a fun twist where all players are involved with each pull of a card. The game includes 400 mind-bending questions spread across 200 cards and covering eight categories—Animals, Literature, History, TV and Movies, Music, Food, Language, and Knowledge. Each category also has one Brain Buster card with three super-difficult questions worth bonus points. It’s perfect for families, college students, or anyone who loves fun facts at any age.
