Puzzle Description:

Chapeau, of the heraldic type. This is what I think of when I hear the word chapeau - a funny hat. Jota used it as a French expression that means Hurray!

Here is the image I used as a model:

It is from the Handbook to English Heraldry

Okay, I'm testing the limits of edge logic again. I think this one is totally workable in your head. But it's a little tricky right from the beginning.

First, you might be tempted to use edge logic on that 13 on the top, or the 8 on the left. You can, but it really won't help that much. You'll just get stuck later anyway.

Look at the 5 on the right. It's easy to see that you need to fill in the dots down the side until there are only 6 open pixels, and you can fill in 4 of them. A few moves later, you are stuck again. It looks like this:

Now look at the 5 on the right again. It can either go up one or down one. If you make it go up and you fill in R14 C30, you will see that forces the 4 in the R19 to interfere with the 3 in R18. That leaves only one choice, to fill in R19 C30. From there, you just use line logic.

The 5 on the right did it for me. Thanks!

Teresa,

I started filling in 11 out of the 16 in R13 with line logic, and then I used edge logic on the 13 in R3 (placing 11 of them) and on the 8 in C1 (placing 7 of them). I also did edge logic on the 4 in R19, and I got nowhere (1 dot placed). Then I used it on the 5 in C30, placing 4 of them. I was essentially where you were at, with a few more pixels placed from doing more solving prior to placing the 5.

It did come down to proving the 5 couldn't go up, and had to be placed, as you said, in R19 C30.

I think you meant "R14," not "R15" in your last paragraph, though.


This looked like a close-up of a weird pair of tweezers. :-)

Thank you, Adam, I made the correction. You'd think I could count by now, huh?

That is really looking 2 moves ahead. There is another way to tackle this with only looking one move ahead.

Once you get to where you were in the picture, you can dot columns 18 - 26 on row 19 with edge logic. Now you when try to fill in the 2 clue on row 14 at columns 29 and 30, R19C30 will be a dot and R19C29 will be black. This makes row 19 invalid.

If we start allowing puzzles to be logically solvable by looking two moves ahead, what's next 3, 4? Where does the madness end?! :)

Ditto your last sentence, Gator.

The madness here never ends here. Once you are hooked, it's all over for normalcy. :-) But if you are tired of my edge logic puzzles, I'll take my madness in another direction. Maybe I could try a Royal Queens puzzle? Nooooooooooo! I'll go design my next Myers Briggs puzzle and think about what I want to do for the WCP.

:) By all means, please keep the edge logic puzzles coming. They are my favorite delicacy - the harder the better.

Ditto #9.

Okay, Gator and Ditto. :-) But I really am yearning for a new Gator puzzle, and I miss those great monkeyboy b/w puzzles. Ah! I see a couple of new Gator puzzles - Woo hoo!

Found to be logically solvable by jan.

fun - i had to start over, but finished easily after i figured it out. whenever i see the word "chapeau", i think:
cat, hat in french chat, chapeau
in spanish he's a gato in a sombrero...

very nice solve
