If Sudoku is boring you, this is the game you should try. I would advise you try an easier version before buying this one. Puzzles are clear, easy to read, large squares. One drawback in this book, however, is that there is either too little a margin or too much print on the edges, hampering writing notes. A minor problem.

I need to thank my friend, Vivian Lee, who sent me as gifts both books, Kakuro Challenge 1 and Kakuro Challenge 2. I have already reviewed Kakuro Challenge 1, and Kakuro Challenge 2 is very similar . Once again one gets a generous helping of 200 kakuro puzzles, ranked in four categories of difficulty. The layouts and difficulty are about the same as in Challenge 1. As you follow your way through the puzzles you will soon find yourself back in old familiar places, such as the intersection of 7-in-3 block with a 4-in-2 block and the friendly attraction of an 11-in-4 block intersecting a 14-in-2 block.

When Alastair comes out with a third kakuro challenge, let us hope that he corrects the last paragraph in the introduction, adds some more advanced hints about using subsets of numbers, and widens the range of puzzle layouts.
