I disagree - I was able to do the entire puzzle by guessing only one square, and it was an easy guess. I think it's a good puzzle, and should stay published. (I'm not even convinced that that one guess was necessary.)

This puzzle has been revised since my previous post. The diagonal lines have been thickened and some additional colorization has been done.

I was able to verify that the puzzle now has only one solution.

However, I have not been able to solve it myself without guessing. It's pretty easy to guess once you get to the point where you have to though.

Someday I'm going to do something to make it clearer when a puzzle's solution changes, like forcing people to post a comment when editting a puzzle that already has comments from other users or something.

Looks like were back to the debate on whether having to use a trial and error process should be called guessing or is still logical reasoning. I think flagging it as 'requires guessing' is misleading - that makes it sound like you have to take a stab in the dark to finish the puzzle, which is not the case. On the other hand, those gray question marks are a good way to find the more challenging but solvable puzzles when I'm looking for something to do.

I think the combination "has a unique solution" and "requires guessing" pretty much means "trial and error required".

Maybe the categories should be "solvable with a pen" and "requires a pencil".

On another puzzle, Robert was able to post a short description explaining how he was able to determine that a particular tricky square had to be colored. If you can explain for each square you set exactly why it had to be that color, then that's what I'd call "logically solvable" or "solvable with a pen" or "solvable without trial and error". If it becomes so complex that you actually have to work it out on the board, then that falls in a different category.

Oh well, if you hate the distinction, ignore it.

For whatever reason, I'm not allowed to save this puzzle. It says error on page. Yet when I goto the puzzle home page, It says the puzzle was saved but when I try to open the file, it says no solution saved???

I don't see how to solve this puzzle. The first column requires 12 red in a row, but there are only 8 rows that begin with red.

I had to guess for this one too.
But it was an obvious guess.
Word.

Found to require some guessing by gator.
