2.0 out of 5 stars
Poor editing: flaws, duplicates, incorrect ratings, April 27 2006
This review is from: Penguin Book Of Nurikabe (Paperback)
Of the 15 "Expert" rated puzzles in this book, there are only 4 that are unique:
#86 = #89 = #93 = #97
#87 = #91 = #95 = #99
#88 = #92 = #96 = #100
#90 = #94 = #98.
That's right, one of the puzzles is repeated three times, and three are repeated four times! I haven't noticed any duplicates in the rest of the book, but I also haven't checked thoroughly. I haven't done too many of the puzzles in the book yet, having only just got it, but at least number 87 (= 91, 95, 99) has a flaw -- it has two potential solutions -- one in the back of the book, and one obtained by swapping the colours of two of the cells adjacent to the 6.
The difficulty throughout the book is on the easy side, though for a book which is likely aimed at newcomers, that's to be expected. Many of the puzzles have far too many "1" clues, which, while they can help the puzzle designer shape the rest of the puzzle, should really be used more sparingly. Here, I never got the sense that they were being used for any purpose than to make the puzzle easier. In one particularly egregious puzzle in the "Intermediate" section, there are 20 ones. That means that 80 cells will be shaded black right off the start. Together with the white cells involved, that's 100 cells of the puzzle solved without any actual thought. The puzzle itself is only 10x14 = 140 cells total.
I haven't done all of the puzzles yet, but even one of the "Expert" puzzles didn't require any actual thinking (just applying the standard automatic tricks over and over, not having to consider the connectedness of the nurikabe in any interesting way, or even use the reachability of cells from islands). Puzzle 30, included in the beginner section because of its size, is actually one of the trickier puzzles in the book, requiring more thought or insight than any of the "Expert" puzzles. I get the feeling that nobody actually sat down and tried the puzzles in the book before it was published.
There are some good puzzles in this book, but all in all, the freely available puzzles at http://janko.at/Raetsel/Nurikabe/index.htm seem a great deal better. I'd usually expect more from a published book.
