 Right challenge level for Killer Sodoku May 04, 2010
This book provides 100 puzzles in the Killer Sudoku format where the clues for solving the traditional soduku 9 by 9 grids are provided by the sums of numbes in adjacent blocks. I enjoyed this book because the puzzles provided enough challenge but weren't so difficult as to become frustrating. For example, this book was more enjoyable than the "Revenge of Killer Sodoku" that fell in the frustrating category for me.

Killer Killer Jan 21, 2010
If you like killer sudoku puzzles (not just hard sudoku puzzles - a different beast entirely) then you will like this. Good puzzles, from easy to difficult...

Terrific Puzzles Jan 14, 2010
This is a terrific book of killer sudoku puzzles. Many of the Medium puzzles are still plenty tough. Highly recommended.
 It is a killer Jan 11, 2009
My husband and I enjoy killer sudoku puzzles more than all others, but they are not easy to find. These puzzles are very difficult. We are still in the medium range in our abilities to solve. This book does have more advanced tips for solving, but we cannot solve a puzzle in an hour.
If you are really skilled, this is the book for you.

 A decent intermediate level book Mar 15, 2007
If you enjoy solving logic puzzles and you'd like to sharpen your mental arithmetic skills, then these are the puzzles for you. These puzzles are similar to Classic Sudoku in that you have to place the numbers 1-9 uniquely in each row, column, and box. The difference is that a Killer Sudoku puzzle is also covered with dotted outline "cages", each of which has a number that indicates the sum of the numbers within the cage and the numbers within the cages must also be unique. There are many techniques that can be used to solve these puzzles, and discovering them is half the fun.
This book contains a two-page Introduction, three pages on "How to Solve a Killer Sudoku", a one-page "List of Unique Number Combinations", 50 Easy puzzles, 35 Medium puzzles, 10 Difficult puzzles, 5 Deadly puzzles, and Solutions. The format is one puzzle per page and the puzzles are a good size (3.75" x 3.75").
The "How to Solve a Killer Sudoku" section gives a fairly minimal explanation of some simple techniques. One of the most important techniques (The Rule of 45) is not even mentioned. If you don't figure this one out you'll have a hard time completing a lot of the harder puzzles. For an excellent explanation of Killer Sudoku solving techniques, see Djape's book "Sudoku K (Killer), Volume 1".
In each section the puzzles tend to progress from easier to harder. There are a couple of hard puzzles in the medium section. A couple of the deadly puzzles are slightly harder than the hard puzzles; the others are about the same as the hard puzzles. I would have preferred fewer easy puzzles and more medium and hard puzzles. Overall, I think this is a good book for intermediate solvers and beginners who learn quickly. For advanced solvers who are looking for more of a challenge, check out Killer Sudoku Online. The Greater Than Killer Sudoku puzzles are especially fiendish.
