It has a unique solution now.

umm adam where have your skills gone??? way to much guessing and that makes it silly

Brain fart, I guess. LOL

Who gave this higher than a 1?

Adam Adam Adam.....*sigh*.

Sorry to get people's hopes up about having a new monkeyboy B/W puzzle to solve. :-)

Indeed! I was partway through and thought, "There's no way Adam made this. Someone has hijacked his screen name."

LOL, speaking of which....

I was able to get to the end with logic - some edge logic, sometimes looking about 2-3 moves ahead. There was always a way to get the next square or blank. This is an extremely hard puzzle.

Woo Hoo! That was my goal. I can say the same thing about your puzzles. :-)

a fairly hard one - good job - no guessing needed - just logic - wish all puzzles were this good and get rid of the guessing ones all together.

hey web master - how about a testing facility like the old japanese site ( i was number one when he died and the site was shut down!) that we (all the good solvers on this site) came from - and don't count any guessing puzzles in the "solved" column so we can see who does GOOD puzzles and skips all the stupid ones (including all those stupid squares and totally fill in puzzles which are a complete waste of time). please, please, PLEASE.

another help - don't let anyone do a puzzle until they have solved about 1000 non-guessing puzzles - that way new people will not start with the same old crap over and over (as a canadian i have solved way too many american flags!!) the new people will also see how to make and do a proper puzzle. love the challenges but to much crap is on this site and the score page is meaningless when a lot of us avoid so many stupid or guessing puzzles and will never even attempt the so we will not move up the standings until these guessing ones are deleted.

I solved this one just out of curiosity. But I have to say I really enjoyed the challenge. It reminds me of a ransom note the way it is pieced together. It was not as awful as some text puzzles because it was not predictable.

I found this puzzle to be quite I challenge, and lots of fun!

I feel this puzzle is logically solvable, so I thought I’d set out to prove it. Here is my attempt to do so.

Line logic solves this puzzle to 50%.

Oddly enough, the best way forward I found from here is internal edge logic on the 1 clue in column 21. If the 1 in column 21 is placed anywhere in rows 19-23, the remaining squares in C21R19-23 are white/dots, and the 5 in column 20 is forced to be in rows 19-23, making C20R19-23 black. This will always cause a contradiction in either R20C20 or R21C20. Thus C21R19-23 must all be white/dots.

Basic line logic now moves the puzzle to 82%.

There is a tricky line logic dot in R3C8 that must be white/dot. After filling in this square, additional line logic moves the puzzle to 83%.

For some reason the hint button doesn’t find the line logic in R16C23, which must be white/dot. Line logic goes on to force R11C23-24 to be black. More line logic moves the puzzle to 85%.

Now some more internal edge logic in row 11. If the rightmost 2 in row 11 goes in columns 28-29, a contradiction occurs in R16C27-29. Thus R11C27-29 must be white/dots.

From here line logic moves the puzzle 88%.

Yet more internal edge logic, this time in row 12. If the leftmost remaining 2 clue is located in R12C13-14, a contradiction occurs in R15C11-12. Thus, R12C14 must be white/dot.

Line logic then solves the rest of the puzzle.

I think I removed any extra steps from this path, but it is possible some of these steps are not necessary. I suspect there are other ways to logically solve this puzzle. I believe all these steps count as moderate lookahead.

I think so!
