Killer Sudoku 1: The Deadly New Dimension

I was hoping to be the first person to review this one, but it appears I'm a couple of days late. When I bought it, I was unsure about whether it'd be good or not because there were no reviews.ON KILLER SUDOKU:I had first encountered Killer Sudoku in Will Shortz's Favorite Sudoku variations. I liked it so much I wanted to get more. It may seem like Killer Sukoku is just some cheap knock off of the original, but I'd say it's what the original should have been. In fact, it'll probably make you bored of the original like it has for me. Killer Sudoku is so much more complex, and gives you a lot of oppurtunities to apply logic that don't exist in the original. It gets to the point in the original that to make them the most difficult, the puzzle solver must resort to the chore of possibility testing to figure it out. In Killer Sudoku there's a lot of tricks you can do involving the sum regions, and that keeps it interesting.Although regular Sudoku has numbers, it doesn't work with numerical values (the numbers could be replaced with letters or even meaningless symbols and you'd still be able to figure it out). In Killer Sudoku the numerical values are crucial to figuring out the puzzles; most of them give you no starting numbers and only give you sum regions instead.ON THIS BOOK:One of the first things I noticed was the Sudoku borders are in BOLD BLACK and that makes them easy to see. In Will Shortz's book with Killer Sudoku, the borders were lighter and less noticable, and I'd sometimes lose track of which 3x3 square I was in. What the first reviewer said about difficulty is mostly true. It rougly gets more difficult from puzzle 1 to 110, but I've found hard ones sooner than they should be and I found a lot of easy ones later than they should be. In fact, I found that the whole "Deadly" section wasn't any harder than the previous section. I really don't know how they came up with the goal times for these. For a few of them I finished in less than half as much of the goal time. For others I used much more than the goal time.I found puzzles 78 and 98 to be the two most difficult ones. Puzzle 78 has a number in a certain area that looks valid, but really it isn't if you look further. Without finding it, I don't think you can make progress. Puzzle 98 involved a sum region trick I had never needed to use before. It took me forever to think of it. I'm very certain you can't go on without figuring it out.

I never get tired of this book. The vast majority of the puzzles are challenging but doable. There are a few that are a bit too easy, but they serve as a good warm-up. There are also a few I still struggle with. The killer variety of Sudoku is my favorite, and this is my favorite book of Killer Sudoku. I've gone through many other books, but none of them hold my interest the way this one does. It's almost as if the puzzles have a sense of humor. This is the best-crafted book I've found. I only wish there were more editions of it.

I like this book but I do wish the squares were slightly larger. The paper feels nice to write on, but it can smudge a little. A few of the difficulty ratings are off but not a huge deal. I wish there were more in the series.

This book was such great fun! If you’ve never done these type of Sudoku before, you should try it. This book has basic instructions to get you started. There are five levels from Gentle to Deadly.After completing all the Gentle, I photocopied the pages before I started the next group. And I just completed them all, the second time directly in the book. By the second time through I realized that I had memorized many possible combinations, but surely not all, so it helped me complete some of them in the suggested minutes.TIP: I found a great website that concisely shows all possible combinations. Google “Brainbashers combinations” and you’ll find it. I could not have completed the more difficult ones without having this site open and handy on my mobile device.TIP 2: If you get to one that stumps you (for me it was 78, 98 105) skip it and move on, since many that follow are easier.I look forward to Killer Sudoku 2!

I got into killer sudoku after becoming tired of regular sudoku puzzles. I find killer sudoku much more satisfying, not because the puzzles are much tougher but because you're always thinking with killer sudoku whereas you usually end up staring blankly at a regular sudoku puzzle, going over the same sections over and over until you find something.I really enjoyed this book because all of the puzzles, even the ones in the supposedly simpler sections, were quite difficult. Some of the ones in the earlier sections proved even more difficult than others in the toughest section. There are even time meters given by the authors for each puzzles, and it is always fun to try to beat them. The book provides over 100 great puzzles hunker down with. I highly recommend it.

I am about to order this book for the third time-- (It's not as if I remember the numbers that belong in the grids). This is very addictive. It calms my mind before I fall asleep, keeps me busy in the bathroom, I carry it around in my purse in case I have a few seconds of down time. It's much more intersting than regular sudoku and it's not necessarily harder (till you get to the end of the book). I like it because there are so many more clues, so many more ways to find the answer than regular sudoku. Buy it at your own risk.

Overall the book is great quality, heavy pages, no bleed when using markers. I was a bit surprised that there are very few puzzles that don’t provide you with any numbers to start with, especially at the beginner and medium levels.It was a bit hard to get into but I will say it did provide a good challenge. If you’re looking for a sudoku book that is more advanced Killer Sudoku, this is the one for you!

Decent paper quality and excellent grid lines, dotted lines and clue numbers. Very easy to see and a decent size puzzle grid. I really enjoyed the 'average solve time' given on each puzzle. It was fun to see if I beat the clock or was slow on a puzzle. If you are brand spanking new to killer sudoku this book does not have an extensive introduction or tutorial on killer solving techniques. I enjoyed the variety of difficulties provided in the book.

La mayoría de sudokus son fáciles. Hay algunos más complejos en las categorías de tricky, tough y deadly, pero se pueden resolver todos.

Hier sind die leichten Rätsel wirklich sehr leicht, so daß ich einige dann ausgelassen habe und meiner Tochter überließ. Die schweren sind dann richtige Knobeleien, mit denen man schon eine Weile beschäftigt ist. Die Zeitangaben sind zwar nicht ganz nachvollziehbar, 10 Min sind dann schon mal 3 Minuten und 60 Min sind dann schon mal 120 Min. Aber was macht das?!Wichtig ist: es knobelt sich nach den SudokuRegeln wunderbar!

Very good buy.

Habe schon viele Killer-Sudokus gelöst,aber diese waren wirklich nicht sehr einfach zu lösen!Es hat Spaß gemacht mal etwas länger nachzudenken,um zu einem Ergebnis zu gelangen!Platz ist ausreichend vorhanden,um Denkstützen zu notieren und die angegebenen Zeitrichtlinien,die man benötigt,um das Rätsel zu lösen sind realistisch!Ausserdem macht es Spaß diese Zeitangabe zu unterbieten!Insgesamt ein gelungener erster Band dieser Reihe!

Diese Siller Sudokus sind im großen Teil relativ leicht zu erarbeiten. Daher kämpft man eher um die angegebenen Zeiten, die mir meist etwas zu hoch angegeben wirken.
