The Times Super Fiendish Su Doku Book 1: 200 of the most treacherous Su Doku puzzles (The Times Su Doku)

I use it to do sudoku. And it is my level

If like me you're addicted to these, it will save you £2.50 each day and reading the Times online.

This is a very good book of puzzles, but they are not really as difficult as Super Fiendish suggests. Nearly all can be solved using just Claims, some contain Gordonian Rectangle short cuts, one puzzle even contains two. A couple are solved using Forcing Loops, some with Forcing Chains. None appear to require any more advanced techniques, although I have still to finish a couple that didn't complete.The Times series of Fiendish and this series of Super Fiendish Puzzles are quite well made and give just enough room in each cell to write all candidates, provided that you write very small. It's a shame that none of the Times publishers actually do Su Doku. If they did then they would spread each puzzle out over more of the A5 page. They might even consider a hard cover version so that both odd and even pages could be easily accessed.I look forward to additional books in this series.

The Time Super Fiendish Su Doku Book One kept me occupied for six weeks of the worse of the winter weather. Challenging but satisfying.

I've been working through the Times fiendish sudoku books for a couple of years. I wanted some that were a bit more challenging where I needed to look for x-wing etc. I've worked through this whole book now and not needed any of the more challenging solutions to solve them. Even the fiendish books would have a couple of more challenging puzzles in each.

Very good
