Absolutely Nasty® Kakuro Level Four (Absolutely Nasty® Series) Spiral-bound – April 2, 2013

I have been doing these kakuro for a few years. I love math. But am not a genius. This level four was a bit too hard but i just cheat a little when I get stuck. I keep improving on my logic by doing these all the time. Great spiral book is pleasant to use. I went back to level 3 again to improve my skills and will do this level again sometime.

This is by far the best Kakuro Series on the market (at least that i have been able to find).I got introduced to kakuro through one of those generic easy > medium > hard books and instantly liked it. I bought the mensa kakuro book, which turned out to be a great book. Then came the black belt and 2nd degree black belts, also great kakuro books. And now the Absolutely Nasty Kakuro series. I bought level 4 first. Lots of math calculations in order to solve, but not impossible! After i completed level 4 i read someones review that level 3 is challenging as well, so bought it and they were right. It is different than level 4 but by no means easy. Because of a lack of other options on the market i just bought level 4 again. What makes the Mensa, Black Belt, and Absolutely Nasty books so great? one puzzle per page, large print, and the pages are big enough to add notes to them in order to solve the puzzles.If you love Kakuro, try out these books!

My favorite kakuro books are the Second-degree Black Belt and the Second-degree Brown Belt books which up to now were the best and the hardest Kakuro books. The present book, Absolutely Nasty Kakuro Level Four, is harder than these: I solve better than 9 out of 10 of the (2nd-degree) Brown and Black Belt books, but so far have only been able to solve 2 out of the first 6 puzzles I've tried from this new book.The quality of paper used for this new series is even better than that used for the Brown and Black belt books. Also, the puzzles are even larger (by 1 additional square across, and 2 additional squares down). The spiral binding is also nice. So, altogether, these new books set a new standard of excellence for Kakuro books!

Husband loves it!!

I completed levels 1-3 and got this book about a week ago. I’m hooked and currently working puzzle #17. These are definitely more challenging than level 3 and have kept me on my toes. I wish there was a level 5.

I have been doing this same book over and over again for a few years now. I’ve tried a couple others, but they aren’t nearly as good. It’s so challenging, but each time, I get a little better. I’ve taken to dog-earring the pages when I don’t have to peek to solve the puzzle. It’s exceedingly diverting, even after all this time. (This is one of those times I am grateful that I DON’T have a photographic memory.:)

I abandoned many of these puzzles when I got stuck. Now I go back to the unfinished ones as I have time, and work them to the end. That usually involves a crib or two.

I was ready to challenge myself beyond the moderately difficult Kakuros. This did the trick!!! These are a challenge but definitely doable
