Publisher's Synopsis
A year of cranial conundrums designed to push your neurons to the limit.
Sanctioned by Mensa, the internationally famous high-IQ society, 365 Brain Puzzlers is a calendar that's not for the (intellectually) faint of heart.
It's like boot camp for your brain, with a devilishly tough mix of more than 300 brain-scratching word puzzles, logic challenges, number problems, mini Sudoku, and more. A set of 20 numbers sums to 85. Each number of the set is first increased by 4, then multiplied by 6, then decreased by 8. What is the sum of the numbers in the new set?* If you're stumped, you can find the answer on the reverse side of each page. Now 100% recyclable and printed on FSC-certified paper.
