5.0 out of 5 stars
I LOVE THESE BOOKS!!!!, August 9, 2007
This review is from: Absolutely Nasty Sudoku Level 2 (Mensa) (Spiral-bound)
These books are so nice! The puzzles are nice and big, and the paper is high quality, which definitely makes it easier. I concur with the previous reviewer, though. Volume 2 is not noticeably harder than Volume 1. However, Volumes 3 & 4 will wear you out! They did me (you might know all the crazy techniques I have yet to learn). The books are really well made and a pleasure to work. I enjoy them immensely, and I hope you do as well!!! :)

These books are difficult, November 30, 2008
This review is from: Absolutely Nasty Sudoku Level 2 (Mensa) (Spiral-bound)
I recently purchased the entire Menza series, and I have to say they've lived up to the Menza criteria. You have to focus and know your solving techniques to get through these without guessing or cheating. Do yourself a favor and purchase the book
Mensa Guide to Solving Sudoku: Hundreds of Puzzles Plus Techniques to Help You Crack Them All (Mensa) to help you learn the techniques used in these puzzles. I started out by letting my wife begin with
Mensa Absolutely Nasty Sudoku Level 1 (Mensa), and I've been working on Level 2.
After familiarizing myself with the solving tips, I went to work on my Level 2. Usually I go straight to the back and try and solve the last puzzle in the book. That kinda tells me how difficult the book will be. That puzzle is still unsolved. I've now worked through the first 65 puzzles in Level 2, starting from #1. I've used the X-Wing technique frequently and also some Swordfishes to get through these, so you'd better be prepared. My wife is also struggling with her Level 1, but mostly due to inefficiant candidate marking and not staying focused on all possibilities while marking. Some of her puzzles have, however, still required an X-Wing to solve.
When I get really stuck, I also tend to use a sudoku tool called Simple Sudoku. This is freeware and can be downloaded from [...]. This tool will allow you to easily see things such as hidden pairs and locked candidates when you build in your book puzzles. Use the filters to find the X-Wings and Swordfishes, and if you still have trouble, the tool will provide you with a hint, although even the hints themselves can be a little difficult to figure out.
These books are definitely for the serious Sudoku puzzlers. I can only imagine how hard the Level 4 book will be, but I'll need to work up to that. Have fun with it!

Good book, but not appreciably harder than level 1, August 5, 2007
This review is from: Absolutely Nasty Sudoku Level 2 (Mensa) (Spiral-bound)
I like this series quite a bit, however, I'm only giving this one 4 stars because as far as I can tell, the puzzles are not any harder than those in
the first level. For my next purchase, I'm skipping level 3 and going right to
level 4. Hopefully those will be harder. See my review of
level 1 for why I like the series.
