Product Description
Product Description
For those who like to live dangerously and push beyond their mental comfort zone, steel yourself for the second book in The Times' toughest Killer series yet.
Prepare for the extreme mental challenge of 120 Deadly-level Killer puzzles, including, exclusive to The Times, 20 Extra Deadly, to really test your limits: this is the only series in which you'll find such a torturous collection.
The Times Ultimate Killer Su Doku 2 is not for the fainthearted. The puzzles use the same 9x9 grid as Su Doku, and have an added mathematical 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 as well.
If the first Ultimate Killer Su Doku didn't scare you off – see how you fare after tackling this one…

No messing with this one. Tricky puzzles from the first page and there are some stinkers. Hours of furrowed brows !!

Having done the first book of this series, I started off in the same vein with this one. That is, I entered in the possibles in each square when the answer was in doubt. I soon found that this was unnecessary and just about every puzzle in the book can be done without any working out and just using my memory. There were perhaps five or so that did require some jotting down of possibilities. Even using this method, in an attempt to eke out a little more difficulty from each puzzle, most were done in around 30 minutes and some only took around 10. I am clearly quite good at these puzzles but certainly no world beater and overall, I have found this book to be far too easy. I will move on to book three and hope to find more of a challenge. I do wish that compilers would stop pussyfooting around with easy puzzles and give the consumer something that really would test us.
It's still the "hardest" series of books that I have yet found for Killer - most that are labelled as "hard" are ridiculously simple.

Having enjoyed the challenges in book 1, I couldn't wait to get hold of book 2. I wasn't disappointed. The puzzles start at deadly (of which there are 100) and move on to Extra Deadly (10 puzzles). These really exercise your mental arithmetic! A target time is given for each puzzle, gradually getting longer as you progress through the book. However, once you get used to the techiniques involved I find that the times are overly pessimistic. The hardest puzzles indicate a time of 2 hours 30 minutes, yet I completed most of the Extra Deadly puzzles in under an hour. I await book 3 with anticipation and look forward to something even more challenging!
