Are You A Secret Genius?, the official puzzle book based on the hit Channel 4 series Secret Genius, will be published by HarperCollins in trade paperback and ebook on 5 November 2026.

Created in partnership with BBC Studios and by the programme-makers Mothership Productions in collaboration with British Mensa, it includes 100 mind-bending puzzles that celebrate reasoning in all its forms.

Readers will be able to test themselves across five different ways of thinking, race against the clock, compare answers with family and friends, and discover that there’s far more than one way to be brilliant.

Based on the latest understanding of how our brains work, these ingenious puzzles reward pattern-spotters of all ages, word lovers, visual thinkers, logical minds and more. Perfect for everyone from curious kids to sharp-thinking grandparents, this is the ultimate puzzle challenge to solve together.

Kayleigh Mapstone, Executive Director of British Mensa, said: “Secret Genius on Channel 4 provided a wonderful stage for bright minds to shine on and has really helped to challenge outdated perceptions of what intelligence ‘looks like’. I’m delighted that Are You A Secret Genius? will provide a further opportunity for anyone interested in seeing how they might handle the games on the show to have a go at home!

“The puzzles in the book draw their inspiration from the world of Secret Genius, and are not only both fun and challenging, but also reflect the latest thinking in the psychology of cognitive abilities. So, if you enjoy the puzzles and discover you’re rather good at them, then perhaps it might also encourage you to discover a little more about where your thinking could take you!”
