New York Times Will Shortz Presents KenKen, The Paperback – May 26, 2009

Amazing. Great puzzles, get progressively harder. Nice having answers in the back. Bought for my dad in the hospital and he won’t stop talking about it! (Happily he is home and well!)

I love KEN KEN. This book had a good variety and kept me occupied for quite awhile. Will definitely order another edition.

Great product, good price

I highly recommend this book for beginners, from seniors to youth, anyone who enjoys math and puzzles. I did the NY Times' KenKen for a year prior to playing it in print. I had several surgeries this year and the simple puzzles in this book allowed me to continue to play a game I love while struggling with the fog of recovery. This is definitely a book FOR BEGINNERS, the "hard" puzzles at the end of the book are only hard compared to the puzzles at the beginning of the book. Again, KenKen is for everyone. From youths who want a fun way to learn math to seniors who need to keep their mind sharp, KenKen is answer!

someone made a digital version but the app was so riddled with ads (literally an ad after every puzzle) that i bought this out of spite.money well spent.

My mom accidentally bought two of these for my sister for Christmas and I ended up with the extra. It’s exactly everything you could hope for in a book of KenKen puzzles. Not too hard or too easy

Great book, loads of fun. I only wish it was spiral bound.

Gave this to my grandson to challenge his teen brain!
