“Widely regarded as the world’s most prolific wellspring of logic games and brainteasers ... if anyone comes up with the next craze, it will be Nikoli”—The New York Times
Just a few simple rules lead to an endless variety of fascinating logical possibilities with nurikabe. Shade the grid so that it contains a connected “river” of black squares. Each number in the grid is part of a different island, and the number indicates how many white squares that island contains. Also, no 2-by-2 square in the grid may be colored entirely black.
The character development ... no, wait, it's not that kind of book.
This is a good puzzle book. They create elegant sudoku that are not too hard. The nurikabe got my least-puzzle-inclined kid asking for more, so I need to find a good book of beginner nurikabe. I learned some good stuff here and definitely improved my nurikabe solving!
