I truly enjoyed working the puzzles in this book.  They raised my level of effort.  I was able to solve all but a couple of puzzles, but very seldom could I finish one in one sitting.  The puzzle answers included 2-to-5 word phrases, which added to the complexity.  The clues were ambiguous enough to prevent an immediate correct response, but were still solvable.  The answers, for the most part, were common usage words or phrases.  I enjoyed it so much I will never go back to puzzles less challenging.  My only criticism is that the print is small to the point that I had to occasionally look very closely to determine if a letter was a lower case o or a lower case a.

I have always been one for great jigsaw puzzles.  I started off small when I was young and as I got older, gradually worked my way up to more intricate and difficult creations.  I would spend hours in my basement putting them together bit by bit, sitting on top of our pool table because that was the only place they would fit by then.

The lure of the jigsaw puzzle, at least for me, was finding that one piece I was looking for to eventually bring me to the final design.  I always knew what the final design was, of course, because it was right on the box that I had bought.  But what if I didn't know what the final construction was?  Wouldn't they be that much more exciting?

John C. Stipa has provided me with my greatest puzzle adventure to date.  No Greater Sacrifice is packed with intricately woven clues that are so fantastically put together, I'm left in awe from how John was able to piece it all together so smoothly.

The use of ancient artifacts, famous heroes and heroines, moving tombstones that uncover secret caverns, and codes used to unlock mysteries, made me feel that I was in an Indiana Jones or National Treasure movie.  No Greater Sacrifice was filled with non-stop action as each clue that was uncovered led to another, until reaching the exhilarating climax, finally allowing you to release your pent-up breath.

The characters in the book were absolutely perfect.  The main characters, Renee and David, were hilarious with their witty dialogue.  The heated attraction for each other was timed and detailed flawlessly throughout the book.  Renee was my favorite type of strong-willed female character.  Finally, the evil antagonists carried the perfect opposing muscle to make Renee and David's adventures treacherous.

No Greater Sacrifice was by far, one of my favorite reads of 2010.  I highly recommend this book to all of you adventure lovers.

This is one of the best puzzle books I have ever bought.  I had been given a version of this book before and enjoyed it so much, I bought two of these as gifts for others.  They loved them as well.  The variety of puzzles adds to the interest level.  I have loved the challenge of looking at a puzzle with the thought it is impossible to solve, then successfully mastering the puzzle.

I really like the very interestingly designed Sudoku puzzles in this book. They are a new take on Sudoku and challenging but not so hard I can't do them. I have not read the whole books yet, but it does just what it claims, demonstrating the math behind the puzzle. I like these authors' other Sudoku puzzle books, too.

I thought I would be bored with the same color all around, but it was very interesting and I really enjoyed doing this puzzle.

This was honestly the most fun puzzle my spouse and I ever built together.  We avoided looking at the box during the process, which ended up being hilarious due to all of the distinct font and artwork types through the puzzle.  It was a cool challenge that way.  The pieces were not very reflective, which made it easier to build under the ceiling fan lights than other puzzles we've done.  Passed it on to my mom afterward to share the fun!

I work sudoku and logic puzzles to keep my brain exercised because my thyroid disease has crippled my ability to concentrate for long periods of time on things. I can sit on the porch with a cup of my favorite beverage, surrounded by cats, cursing my puzzle-solving skills, and solidifying my reputation as the neighborhood weirdo.

I particularly enjoy the alternative puzzle shapes for Sudoku; the snowflake one being a favorite.

This book has some puzzles that kind of made my brain hurt just looking at them so I know I shall be delightfully entertained and frustrated at the same time.

Having been disappointed by a number of crossword puzzles book that "claim" to be easy, this series is TRULY what it claims. These puzzles really help those of us who enjoy successfully completing a puzzle without using a dictionary, cheating by looking at the answers, or feeling like a failure when only 1/3 of the puzzle is within my scope of information. Success is contagious and totally addictive, as are these puzzles. Bravo to Will Shortz and THIS SERIES for providing us with these accomplishments.

I am presently working this puzzle, and I just love it!  The bright colors and patterns make it a pleasure to work.  Also, the distinct patterns and colors make it possible for a less experienced worker of puzzles to manage a 1000-piece puzzle.  It is very challenging without being frustrating.

There are three things I really appreciate about this book. First, the paper is of good quality so my favorite gel pen ink doesn't bleed through and spoil the puzzle on the other side of the page. Second, the binding is a covered spiral, so I can fold the book in half to do puzzles on my lap. Finally, and this is the most important, the puzzles are challenging enough to keep me working hard, but not so tough that I give up on them. There was a second volume of these anacrostics which appears to be out of print, and I hope they reissue it, because they're so enjoyable.

I couldn't wait to get this book, that as soon as it arrived on my doorstep I started working on the puzzles. It is a very fun way to pass the time. There are book excerpts from all of the Bluestocking Belles, word searches, mazes, and matching games. I wish there was an answer key in the back to see if I got my answers correct and it would have been easier to do the puzzles if they were on the right side instead of on the left side. Other than that, I enjoyed it a lot. I hope they do more of this in the future.

This was my first experience with this type of mystery puzzle. I loved the challenge even though it really was quite a challenge not knowing what the puzzle actually would look like. It was also challenging because of the colors. I felt very pleased and accomplished when I finished this one. The clues do make sense. I definitely want to work on others of this type in the future. The pieces were good quality, thickness and size.

This is a very fun set of physics puzzlers that lead the reader to a deeper understanding of how things work.

Each of these puzzles was challenging but doable, some requiring several sessions. The spiral construction made holding it and writing answers and guesses comfortable. I'm almost finished the book and will be sorry when I do.

I love this book! All those who enjoy puzzles will love the format of this book - which are short puzzles that require nothing but a little brainpower to figure out.

Many of the puzzles you can't figure out will have you slapping your forehead and shouting, "Of COURSE!" when the answer is revealed. That's the fun of puzzles like these, in my opinion. Add to this the wide variety of puzzles you'll find in this book - something for everyone for sure - and you'll consider this book among your puzzle book favorites. It makes a great gift too!
