This review is from: The Times Fiendish Su Doku (Paperback)
It's difficult to judge other people's reviews because you don't know what their standard is compared to your own; so to help other readers, this is where I'm at. If there is a selection of sudokus to choose from (in a newspaper) I always go for the difficult one first as the others are now too easy. That's not to say, I whizz through the difficult ones, but I can do them and, now, they're the only ones I find remotely satisfying.
So I bought this book in the hope that I would have some puzzles to get my teeth into; this is what I found: usually, it is easy to fill in say 10 numbers and then comes the block, which can take (well me anyway) ages to find where the next cell possible to fill lies. In the meantime, numerous blocks, lines, columns have accumulated two, four or even six cells that only two figures can go into. Once you solve the current block (only one per puzzle), all the other numbers 'collapse' and it is just a matter of filling in the only possible number that can be in the remaining cells. You can see the answers faster than you can write them in. There are no further blocks to tussle with. It's very frustrating and deeply disappointing.
These puzzles rely solely on 'naked pairs' and 'hidden pairs'. I should add that I'm still not convinced about the tactic behind 'hidden pairs' as sometimes it seems to work and sometimes it doesn't. This may be because there is some other factor to be taken into account of which I am unaware. (I suspect this may be the case - I am by no means a Sudoku expert.) If you have full command of this tactic, then you will find this book even more disappointing than I do.
This book is now deep in my bedside locker and only comes out when I can't sleep and all other reading matter has been finished.
