 A good introductory kakuro exercise set Feb 28, 2006
By William E. Margolis
This book presents us with a graded series of kakuro challenges.
The introduction is quite clear on strategy, although the Divide and Conquer section has a few paragraphs that hopefully will be corrected in later editions. However, Chisolm looks only at the case where a single digit has been discovered. As with Sudoku, a very useful tactic focuses on discovering pairs of cells that must choose from the same two candidates. In Kakuro one may sum the two choices and subtract from the block total to give information about the other cells. Similarly for three cells with three candidates, etc.
The challenges are presented in four levels of difficulty. The first level problems are presented on an 8 by 8 grid, the longest blocks are of length 5. The second level grids are 10 by 10. The third level are on a 10 by 12 grid, with some blocks of length 6. The fourth level are also on 10 by 12 grids, with a few length 7 blocks.
There are no length 8 or length 9 blocks.
It is possible to do the first level in ink, without having to record intermediate guesses. The proper choices are pretty much locally determined by the situation in blocks not more than two or three cells away. This is not true of later levels, in which some choices require resolution of situations at more distant cells. A good pencil and eraser is essential.
I worked through all 201 puzzles and found the book to be effective in acquiring improved facility.

 Don't waste your time Jan 02, 2009

I am so disappointed in this book. I thought there might actually be a challenge here. The malicious are a joke. I could do these while drunk and half asleep. If you are new to kakuro, go for it but if you have been doing this for awhile, this book is a HUGE waste of time.
 Love it Dec 09, 2011

I'm loving it. I'm halfway through now, and finding the puzzle a little more challenging than the first half. The Delicious puzzles were too easy, but that was expected.
 Moderately good Dec 19, 2010
By David H. Copp
The strength and weakness of this book is that it contains four different difficulty levels. For most people only one or two of the levels are challenging.
That said, the puzzles are good and the difficulty grading is accurate.
easy to very hard Oct 01, 2010
By Charlotte S. Lovejoy
This book moves from very very easy basic puzzles to very difficult ones - all fun.
