Killer Sudoku: 101 Puzzles

Introduced by The Times, the British publisher who pioneered the sudoku craze, the “killer sudoku” poses a double challenge: the basic rules of sudoku still apply, but puzzles initially have no numbers showing. All that is known is the sum of the numbers inside irregular boxes, called cages, in which the classic 9 x 9 sudoku grid is subdivided. Killer Sudoku contains 101 of these brain-busters grouped into six levels of difficulty. The introduction explains the basic techniques needed to solve these new versions of the world's most popular number puzzle.

4Fun but difficult  Dec 02, 2009
These puzzles are doable, but they do require more concentration than most other killer sudoku books I have completed.

5Best publisher!  Sep 01, 2009
Yes! The page quality is great and that's a big issue for me. Yes! This author is an artist. I agree with all the other reveiwers who gave this a five star. When I compare the enjoyment i get from other publishers (Times, Shorten, Mensa, "Official" etc) I always come back to djape. I don't know if this guy uses computerised methods to create his masterpieces, but if he does, it's not showing. As with stated hand-worked puzzles, there is a certain feel that you don't generally get with the computerised versions. I have various books of killer, jigsaw, samurai and combination in various places in my house, and will always find something to engage me, whether it's a more simple puzzle coz Ihave to do the shopping soon, or the lovely feeling of sitting back and poring over a killer jigsaw samurai. Mmmmmmmmmmmmmm. I hope he publishes more, because I will have finished all his books before too long, and then what am I going to do?

5Not for the faint of heart  Dec 30, 2008
Yes, these are extremely difficult puzzles (beginners start elsewhere!). When I first started this book, I thought they went too far. However, I plugged away at them, discovered new methods along the way, and slowly but surely improved my skill level until I could almost do them all. Yeah, the highest "IQ" level puzzles are ridiculous - I could only solve about half of them... but I like being challenged. I hate to reach a certain level and think there's no more room for improvement (except for speed I suppose), so many other logic puzzles have become too boring for me now. Another thing I like about killer sudoku is that you'll know sooner that you've made a mistake. Ever do a plain sudoku and find at the VERY end that you went wrong? You erase the whole thing and start over. That rarely happens with killer sudoku. With the added layer of sum cages, you'll realize you're off more quickly.
Many times I'll think I'm stuck on one, then come back the next day and see something I missed before. That's what I love about killer sudoku. They're so much more complicated, and for me, more interesting.

5killer sudoku  Sep 09, 2008
great group of puzzles! these are "thinkers" and not the trivial puzzles you find in some of the other collections. However I did find two puzzles in this book with unsolvable rectangles (and therefore there is no solution to
the puzzle).

5Perfect!  Dec 23, 2007
I've been doing Killer Sudokus for more than a year and enjoy them far more than traditional sudoku. This is a very nice collection with a range of difficulties that excludes both the easiest and very hardest I've ever seen. (Nothing as hard as the "Mind Bending" found on a popular killer sudoku website--and nothing quite as easy as the "easy" puzzles on that site either.) I'm nearly through this one and will either go back with a big eraser to start over again or buy another copy!

And: if you've never done Killer Sudokus before, it includes a little primer on the tricks for doing this kind of puzzle at the front of the book.
