Special and Unique!
5 plus stars! Excellent and unique books by this author, challenging and so much fun! The best part...they are different than all other puzzle books I've seen. NEW ways to challenge your memory and thought processes! Especially perfect for seniors who enjoy variety, trying new word and memory puzzle types.

Fun and very good to help keep your brain functioning.
I received this book as a gift, I just love it. It is challenging but not to the point of being too hard. So many different games and puzzles. Something for everyone. I liked it so much I bought on for 4 of my sisters.

Well worth it, hours of fun
This book is a hoot full of all kinds of fun puzzles and brain teasers . Keeps you busy and quality printing and heavy weight paper pages. Well worth it.

Great except for one flaw
This is an excellent, fun book of puzzles. It really is amazing how fun these are. If you don't know an answer, it teaches you something. The only reason I don't give it five stars is that there are no page numbers for the answers. To get to the answers, you have to look in the back and navigate to the page number that the answer corresponds to. She learned something because her sequel book (417 More Games, Puzzles....) have the page number of the answers.

Fun variety of questions to work
I like the variety of questions that make you think. Fun to work without being like a school test. It's easy to work a few put it down then pick up the book later. The spiral bound book makes it easy to lie flat. I've had 2 strokes and holding a book is difficult at times.

Tap your brain
I love this puzzle book. I received it as a gift when I retired. My friend didn't want my brain to atrophy. I've given it to several friends as retirement gifts and when they were rehabbing from surgery. I really enjoy the variety of challange in this one book

A mixed bag of fun challenges + ridiculously outdated trivia
We highly recommend half of this book. It's full of challenges that are accessible by almost anyone, and there's a lot of variety. For instance, you might be given two different word definitions & have to name a homonym set that fits. Or you might be tasked with listing 26 different color names, one for each letter of the alphabet. Or come up with a list of words that begin with the prefix "ant-" based on various clues. We find these types of puzzles both challenging & genuinely fun. And for most of them, they're the types of challenges that you can read aloud to a group--or to a significant other--to enjoyably while away a long road trip. But then there's the other half of the book. That's the half filled with some of the most useless trivia from long gone eras. You might be asked about a wealthy socialite from the 1920s, or a slightly famous murder trial that took place during the Great Depression. Occasionally there are questions from the 1990s or--even more rarely--from the 2000s. But these are few & far between. For the most part, you'll get a lot of questions that you're really only likely to know if you lived during the early-to-mid 20th century. In retrospect, the cover text is very revealing: the book claims these puzzles were designed to "keep your brain young." That makes sense if it was written with an an older audience in mind. Bottom line: if you were born in the 1940s and enjoy word puzzles & trivia, it's a no-brainer to buy this book--you'll probably enjoy every page. If you were born in the 1970s, you're going to struggle a lot but you'll still get a lot out of it. And if you were born in the 1990s or later: enjoy the word challenges, but prepare to skip many, many pages & roll your eyes a lot.

Lots of Variety
This is a large collection of puzzles with a great variety of puzzle types and varying skill levels. Most puzzles and answers seem fairly easy (which give you a sense of accomplishment), however there's always a few in each puzzle that are a little more difficult and make you think a little harder, which is the whole point. I would recommend this book.
