Product Description

Killer Su Doku poses an even greater challenge than the fiendish Su Doku puzzles. Here are 100 previously unpublished puzzles for hard-core Su Doku addicts. Published to coincide with the launch of Killer Su Doku in the "The Times" this September, this takes Su Doku to the next level. The puzzles use the same 9x9 grid but there is a double challenge. The aim is not only to complete every row, column and cube so that it contains the digits 1-9, it is also necessary to ensure that the outlined cubes add up to the same number. Killer Su Doku is enormously popular in Japan and the craze will no doubt catch on in the UK.

Excellent Puzzle Book
A very interesting new variation on the 'Sudoku' puzzle type, which is certain to become more and more popular. It's a combination, really, of both Sudoku and Kakuro - a combination which enables the composer and solver to set and solve puzzles using techniques familiar to the foundation puzzle types and also ideas unique to 'killers' such as 'nonet counting'.

These are hand compiled (and often symmetrical) puzzles by Japaneze puzzle experts and, with over 100 puzzles of varying degrees of difficulty, this book should give many, many hours of puzzling entertainment. Many more so than the publishers themselves estimate as I find the target times totally unobtainable!

Thoroughly recommended.

Can't put it down
Beautifully crafted puzzles that are graded and ordered by the amount of time you're expected to solve them in - from a few minutes right up to 90! I like the way they seem to be ordered so that each puzzle brings something new to the previous one.

All you'll need for this is some Su Doku skills, some really basic maths (subtracting from 45 is a good start), a pen, your thinking head and plenty of time.

More addictive than Sudoku
Killer SuDoku is so much more entertaining than SuDoku. The grid is the familiar 9x9 but most grids have no starting numbers. The only clues are the groups of squares with the total in the top left. If you have ever played SuDoku and Kakuro then you will find it easy to get started. Unlike ordinary SuDoku it can require some arithmetic. Each puzzle has a time it should take which range from 7 minutes to 90 minutes. You can always skip some of the "Gentle" and "Moderate" puzzles if you find them too easy, or save them for when you are feeling brain-dead. I'm not sure I every want to go back to ordinary SuDoku again!

The Times puzzles are well constructed and it seems like they have been designed with a particular route to the answer in mind. There are not many Killer Su Doku books around at the moment but this is probably the best.
