Late breaking news! You don't paper and pencil to work these Nurikable puzzles anymore. I've implemented then on Javascript boards:

**New**#22a, smallish but not easy**New**#22b,*much*easier variation on #22a**New**#22c, another variation on #22a**Recommended**An interactive board on which to play the Wikipedia example.**Recommended**An interactive board on which to play #1.

#1, the very first Nurikabe I constructed, is also my favorite. While far from easy, it is quite do-able. Very early you will be able to locate the entire 14-chain. You will also be able to see white fences and constrained white regions that dictate the general paths of some black chains.

I've started to construct Nurikabe puzzles. These are fun to solve! And fun to construct!

Since the large Nurikabes tended to be much too difficult, I started making smaller ones. #16 is my first 9x9 ... yet it seems to be as ridiculously difficult as some of the 13x13's!

I've numbered them in the order I created them,
not by difficulty. It seems easier for me to
construct hard ones than easy ones, so most
of these are just too darned difficult to be fun. :-(
(I dropped this project for four years, then did the
Nurikabe Javascript and decided to make more puzzles, somewhat
easier than before. #12 is the first of these
new puzzles. For these I provide **only** the Nurikabe board,
which will inform you when you have a correct solution.
(If you give up and insist on knowing the solution, e-mail me.)

Each of these puzzles has exactly one solution.
If you regard this fact as a given, you may be able to
make certain special inferences (*OWFU's*, or
only-way-for-uniqueness).
Puzzle #11 is one where OWFU's might speed up the solution
process.

Rather difficult but requiring no trial and error:

- #1 and detailed step-by-step solution.
- #8 and #9 and detailed step-by-step solutions.
- #10 and solution.

**Very** challenging, perhaps requiring
deductions that could be classified as trial-and-error,
but still fun and doable by expert nurikaber's:

- #5 and detailed solution.
- #11 and detailed solution.

Too Difficult, brutal trial and error seems to be required:

- #2 and solution. (This one may be fiendishly difficult, but please peek at the neat solution!)
- #3 and solution.
- #4 and solution.
- #6 and #7 and solutions.

- Three dominoes puzzles.
I think you will agree these are
*much*higher quality than the Dominoes Puzzles currently being published by*Dell*. - Detailed solution to Dominoes Puzzle 3.

- Many puzzles are, like Nurikabe, of the
**Grid-filling**type. Battleship solitaire puzzles are fun. A simpler type, which can also be fun, are

ABC and ABCD puzzles. - Figure out this family tree. (I'm very proud of this difficult puzzle.)
