Customer comments on this selection.
 I love killer Sudoku, the math and the logic are great.
If you like Sudoku but find it a little boring try the killer puzzles. Math additions make this an exciting book. I have done this book twice already, and it was just as enjoyable the second time as the first.
Better than regular Sudoku
I encountered Killer Sudoku in a Will Shortz sudoku variants book and became hooked on it, and this is a great book of it. It allows you to move between a variety of solving techniques taken from both regular Sudoku and Kakuro. The puzzles here come in a good variety of solving difficulty, with enough easy ones for you to practice your techniques on, and enough challenging ones that you won't get bored.
Solid and fun
I ran into Killer Sudoku accidentally, and became hooked ever since. The (simple addition and subtraction) math involved adds a new dimension to the puzzle. Unlike the standard Sudoku, Killer Sudoku puzzles have more twists and surprises waiting to be explored. The more difficult puzzles in this book are very satisfactory in harboring many pleasant and exciting ones.
The books contain 110 puzzles of 5 levels. When you advance to the last two level, your skill and fun are elevated as well. I guess after you mastered the game, you may want to get books with only difficult ones (and they should be so published). One nice thing about this book is that the puzzles seem to have been tested, and there is a 'par' time for each one of them. For easy one the pars are ten to 20 minutes, and the hardest ones up to 90 minutes. These par times are pretty good in that I tended to exceed them in the beginning, but after I have advanced to high levels and came back to do some easier ones that I skipped I often beat the par. The time competition factor also is a way to enjoy the easy ones.
Highly recommended for going through the levels and mastering the game. If you are looking only for tough Killer Sudoku books, this one contains about 20 very good ones.
A must for the Sudoku bored
If your bored of Sudoku and not finding the standard puzzles challenging you need to try these out. The page layout of this book is good there is ample room to write your number combinations and there are suggested times for each puzzle. The paper used in the book is softer but stands up fine to an eraser.
Plenty of fun
I do enjoy regular Sudoku. But there are a couple of problems with it. First, while it uses numbers, it in no way uses the properties of numbers. Second, the level of effort to solve such puzzles is generally uneven; you may get a few numbers early, but then it gets very tough, and soon after that it is easy again. When it is tough, you may have to write down possible values in a square or guess, and that's unsatisfying compared to being able to simply write down correct numbers in blank squares.
With Killer Sudoku, one does get to use the additive properties of numbers, so there really is a difference between the symbols! And the level of effort is more nearly even. In addition, even hard puzzles generally can be solved without writing anything down but the answers. It is my favorite Sudoku variant ("Greater than Killer Sudoku" is my second favorite).
This book is about at the right level. Do not be scared by the "deadly" puzzles at the end, as I found them to be easier than some of the earlier ones.
I recommend this book to all those who enjoy a challenge and have some time on their hands.
