The Times Ultimate Killer Su Doku: Book 13: 200 Challenging Puzzles from The Tmes

These aren't bad though the "Deadly" aren't very deadly. What I really dislike with the Time books is that they feel we want to be taken on a journey starting at the easiest and working upwards. Maybe the very first time you buy a book but not once you have mastered one.Just mix them up - I alternate from front to back and sometimes middle so I dont get all the hard ones at the end. I think Stefan Heine's Hardcore (#4) is a much better collection - a pity it is the only one.

I love killer suduko but these are way too hard. No start point and often find myself with a 50-50 guess it most puzzles. We want them to be difficult but not to the point of having to guess

The puzzles as always are great - I love killer su doku puzzles. Just disappointed that the cover was damaged even though it’s supposed to be new.

Bought for a present but good book.

Seen some of puzzles before in previous books ???
