It's all about the puzzles

This game doesn't have hidden object puzzles and has very few inventory puzzles. What it does have is a lot of brain-teaser, math, and logic puzzles. The presentation is professional. The plot is brief, but provides a nice background to the puzzles.

If you are like me and just want challenging puzzles in your puzzle games without all the added fluff, then this game is for you. My only complaint is sometimes you are missing an important clue to a puzzle and the game doesn't always let you know. For example, I wasted a lot a time on the "colored laser" puzzle before giving up and trying a different puzzle. Lo and Behold, when I solved that puzzle, I got the clue that makes solving the "colored laser" possible. Why couldn't they not activiate the first puzzle until the puzzle with the clue is solved first?

Finally, I think the Snooker puzzle might be one of the best puzzles in a game ever. I strongly recommend not "cheating" on this one. It was rather satisifying for me when I finally solved it on my own!

Puzzles are my favorite indulgences (along with reading). I'm enjoying the variety of puzzles in these books.

This book has 84 puzzles which start a little easy and progress in difficulty through the book. I'm intending it for my 9 year old who needs more challenging fun to help him learn to problem solve. I think that as he starts to do the puzzles he'll be able to build on that knowledge and continue through the book. There is only one puzzle on each page and there is an answer key in the back.

The puzzles have a large logic component and lots of them use math reasoning for figuring. I don't think there will be any which are too difficult for him.

I love the puzzle.  It was a challenge but that's what I look for in a good puzzle.

An excellent book of puzzles for someone new or an old hand at these brainteasers. Just as an aside,the copy I have was printed in the UK by Running Press,but the cover is the same as shown here;although the description says there are only "over 300" puzzles,not 400. It alo states it has 512 pages where mine has 480. However,I think they are much the same book.
 The author,Nathan Haselbauer ,is the founder and president of The International High I.Q.Society. As far as I know this is the 3rd such book of puzzles he has published,all in recent years. He is not as well known for Mensa type puzzles as some of the others we are familiar with on this side of the "big Pond".By and large the puzzles are of the "Quick" type,and many can be solved in the matter of a couple of minutes. Then,there are others that will take considerably longer. There is not much in the way of new or original puzzles,as they are the type that are quite common. Answers ,though little in the way of clues or explanations, are given to all the puzzles. There is a good mix of puzzles,but there is a fair amount of type repetition .For instance with puzzles such as Sudoku,Spot the Difference,Mazes,Buy-Buy,Jigsaw Puzzles,Shadows,Stamp It Out,Box Clever,Sequence Conundrum,Hexagony,Odd One Out,Follow The Thread,Shape Spotter,Cut Out,In The Count,etc,there are several of each.
 Several of the puzzles such as the Jigsaw and Hexagony could be made up in cardboard or wood a puzzles for anyone who likes to construct puzzles.
 For those interested, there is an excellent website [...] that gives information on the Society and a nice group of puzzles,and somewhat different from those found in the book.
 Anyone interested in puzzles will get a lot of enjoyment from this collecion of puzzles and particularly if wanting a change from just Crosswords,Wordsearch and Sudoku.

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.

The puzzles require thought, the bonus is Mr. Reagle's sense of humor.  This stands for all of his crossword puzzle books.

The pieces are varied shapes, which is good, and they fit well -- no doubt about whether the piece is the right one.  Perfect puzzles.

There are 180 jumble puzzles in this book with a couple levels of difficulty.  The book is like a large coloring book and, for the most part, has larger print (which I like). hours of fun for the jumble puzzle lover

I've enjoyed going through these puzzles so far (on page 32 right now). Some are pretty challenging, even on level 1. The thing I like the best about this book is the variety. Great mental warm-up before diving into work.

I had a great time completing these puzzles. There are twenty different types of puzzles in this book. Some of the puzzles were old favorites - Battleship, Dominoes and Number Place, but most of them were new to me. This was a welcome change from the same old puzzles I had been doing for years.
Some of the puzzles can be found in Games Magazine or Dell's Math and Logic Problems magazine. If you like those magazines, but crave a little more variety, then you'll love this book.  Unlike those magazines, there are no word problems in this book. In fact, none of the puzzles required any reading at all. No real math is required either. They all used some type of square grid format that is appealing to mathematical and logical minds.

This is a really high quality puzzle book, with great puzzles, good quality paper (you can erase puzzles and redo them later), and spiral binding. You get a lot of puzzles for your money. I wish the authors would create a second edition! The other Mensa books just don't compare. If you like this book, you'll probably also like Mind Sharpening Pixel Puzzles and Perplexing Pixel Puzzles.

Not often do you get to have fun and do some light brain excercises at the same time. If you like puzzles, this game will not disappoint you and is appropriate for all ages. What's nice is that the game has a variety of puzzles, but is not repeitive even though they've worked in such a large volume of brain teasers and hidden them all over the city. I only hope and pray that they will make another!

A solid product. The margins on the "grid" of squares can be different sizes. Anybody who likes puzzles will like this, and they'll love it if they like origami as well. I'll probably burn through these puzzles in a couple days, but once you reach #27, they take a while to solve. I'll expect I'll burn through a couple podcasts and albums folding/solving these.

This such a good game; it combines puzzle solving, thinking ahead and simple "quest" theme....plus the game changes everytime you take a turn.

I thoroughly enjoyed the puzzles in this book. I received many hours of entertainment, and learned a great deal as well. But, being a layman and not knowing much at all about mathematics, some of the later problems were rather difficult. A few of the problems had writing that was difficult to understand. But overall, I thoroughly enjoyed the challenge and definitely recommend it!

Great puzzles--except for a few quirky ones that only the constructor could possibly know answers.
I feel these are good  exercises for my 90-year old brain.

The puzzle: using the eight dog silhouette cards and one solid black card, make a stack to produce one of the eight designs shown in the booklet.

I found this considerably easier than the classic Rabbit Silhouette puzzle (ThinkFun made a version of that back when they were called Binary Arts). Because the cards in this puzzle are square, there are only four possible rotations for each one, doubling to eight once you include flipping the cards over. The order of the stack matters, so there are lots of possible combinations, but you can get clues to the order by looking at the puzzle goal and seeing how much of each color is visible.

The puzzle was created by Ron Dubren, who has designed quite a few puzzles and toys, including Rubik's Rabbits and Nemesis Factor. He is also the co-inventor of Tickle Me Elmo.

The cards are plastic-coated cardboard, and should hold up pretty well, though it is possible to fold them if you are careless. It comes with a fairly sturdy plastic tray that you can use to display your solution. The color scheme is attractive and well chosen, though you do have to pay attention to make sure you don't confuse the two shades of gray. I would recommend this for adults and older kids/teens, as I suspect younger kids would not find it as interesting.

I enjoyed the puzzle quite a bit. Between the colors and the moderate difficult level, it was kind of soothing (unlike some puzzles which lean more toward frustrating) and was satisfying to solve.

Disclaimer: I know some of the people who work for ThinkFun, and I got a free copy of the puzzle to try out. However, I loved their stuff long before I knew anyone there, and have bought pretty much everything they have ever produced.
