Test your mental mettle.
Here's the perfect calendar for people who love to start their day with
a challenge. A lively mix of word puzzles, number problems, logic
quandaries, and other cranial conundrums, this is the only calendar with
puzzles so tough they're sanctioned by Mensa(R), the internationally
famous high-IQ society. Put on your equation hat with Criss-Cross Math.
Deduce a secret number in Spymaster. Decode the symbols in A Symbol
Task. And don't worry if you can't solve one, because answers are
printed on the reverse of each page. Printed on responsibly sourced
paper and 100% recyclable.
