No reason to be embarrassed. You just haven't learn the various solving techniques yet.

On two different edges there are an adjacent 3 and 5. There are six possible squares for a number on the edge to fill. For the 5: if three of the squares are taken by the 3, then the other two squares on the opposite side of the 5 are filled. That then makes the two squares on the other side of the 3 blank. This technique works any time adjacent numbers on an edge are different by two (1/3; 2/4; 3/5; 4/6). It's similar to adjacent numbers in the middle of the puzzle being different by three.

I hope this makes sense; I don't know how to edit your screenshot to mark it. If it's not clear, let me know and I'll try again.

Hi Charlene, how do you know that the square directly underneath the 3 is or isn't filled?

This puzzle has entirely too many 3s and 5s. :-)

In the explanation, R=row and C=column. I figured out how to mark up the graphic, too.

Jen, I'm assuming you mean the 3s in the first row, yes? (R1:C2 & R1:C4)

Given my explanation in the previous message, squares R1:C6 and R2:C6 are filled. Squares R1:C3 and R2:C3 are blank.

Look at the 5 (R3:C3). The square above it is now blank. It has a 3 below it. Therefore the two blanks above that 5 are filled.

So, the squares directly underneath the 3s in the first row are both filled.

Starting from the top of the thread, how far did you get before the explanation confused you? I'll try to explain it a different way.

Thank you for responding.
I am at the beginging. Why are Squares R1:C3 and R2:C3 are blank. How do you come up with the decision. I understand why R1:C6 and R2:C6 are filled. Why does that leave R1:C3 and R2:C3 blank.

Using the second picture, look at the 5 at R1:C5.

Three of the five squares filled in; we need five. Therefore, we know that two of the three blank squares will be filled in; we just don't know which ones yet.

Later, when the two missing squares from the 5 are filled, it will also complete the 3 at R1:C4. That means, regardless of which two of squares are later filled, the two squares to the right of the 3 will be blank (R1:C3 and R2:C3).

Looking at the 3 / 5 in C1 has the same logic. The two square below are filled (R6:C1 and R6:C2) and the two square above are blank (R3:C1 and R3:C2).

This works whenever two adjacent clues on the edge are within two of each other: 1/3; 2/4; 3/5; 4/6.

It also works whenver two clues in the middle are within three of each other: 1/4; 2/5; 3/6; 4/7; 5/8; 6/9.

The rule of thumb is: the squares on the higher clue's side are filled and the squares on the lower clue's side are blank.

Hope that helps. If not, let me know.

I feel like an idiot too. I've also been stuck on this stupid puzzle for literally years. I'm usually very good at logic puzzles - even mastering the "hard" Pic-a-Pix puzzles, etc., and I've done all levels of Fill-a-Pix "basic"...but for some reason, I just can't get my head around these advanced logic ones!! The "techniques" step-by-step instructions on the app and website are laughable. They only show a mostly basic puzzle, with only one "advanced logic" instruction at step 4, and the rest is all basic logic. How is that supposed to help anyone??

Charlene, I've read and re-read your instructions and, like newattd1, I get why R1:C6 and R2:C6 are filled, and that R1:C3 and R2:C3 are blank, but after that I'm stuck again. How do you determine which of the remaining 4 squares is blank? It seems to me that it could be any of them.

What I really need (I think all of us confused ones need) is a step-by-step for the whole puzzle. I think then it might sink in. I just know that this is a case where once I "get it", it's going to click and I'm going to have no trouble, but I've found literally no good help on the internet anywhere and just can't figure it out on my own.

Help!!

Since you didn't specify, I'm assuming you mean the other four squares of the 3/5 pairs on the side? Those can't be determined yet. Therefore, we need to look at other clues that *can* be solved. I tried marking this up in Paint, but it's gotten too messy; it would really help to have a new screenshot of the progress to date (I don't have access to this puzzle).

Look at the 5 at R3:C3. Based on the previously marked squares, the three squares on the row above the 5 are filled-blank-filled. So, we have two of the needed five squares. The clue below the 5 is a 3; therefore, the three needed squares for the 5 satisify that 3 so the three squares below the 3 are blanks (R5:C2,3,4).

Since we know that R5:C2 is blank, we now know which three of the four squares are filled on the left edge 3/5 pair.

If you search the old forum messages, there are links to helpful documents for solving the puzzles; however, some of the links are long dead. The Wayback Machine at archive.org might be helpful.

Also, searching the internet for "Fill a Pix" turns up lots of sites; I don't know if they are puzzles-only or have other instructions. I can't remember if Fill-a-Pix goes by other names; I know Pic-a-Pix has several different names.

Thank you ever so much for your patience in explaining this!

Okay, so for my question above, I'm stumped on how you determined that the squares R2:C2 & C4 are filled (green boxes in the attachment).

Great, a new graphic!

It's helpful to use the larger red square until you get the hang of solving these puzzles. The little square (like you have on the 5 in R2) can be confusing.

Looking at the 5 in the middle of the big red box, you'll see the 3 below it. That tells you that three of the six squares of the 5 *might* be filled in; it's possible one, two, or all three of the 3's squares are below it; if warrants a further look.

*If* the three of the six squares are filled, that leaves two squares left for the 5 (5-3=2). You know that the 5 in R2 is filled, so there are only two squares left. Therefore, the two squares in green must be filled in. This wouldn't work if there wasn't already one blank square in R2.

To look at it a slightly different way. Think: What if the two squares in green were both blank; what would happen?

That would mean all five squares for the 5 are in the six bottom squares of the red box. That doesn't work because of the 3 in R4:C3.

OK, what if only one of the green squares is filled? That would make four of the bottom six squares of the 5 filled which also doesn't work because of the 3.

Therefore, both green squares must be filled in.

I hope that isn't too confusing; it seems complicated because I'm trying to explain different ways of looking at it.

My personal way of approaching this particular clue would be to center the red box on the five (as I did in the graphic). I'd see there might be three squares filled, there are only two squares left available, therefore the green squares must be filled. That comes from practice; after a while you just start seeing these sorts of things.

Always feel free to post if you get stuck. Folks here are friendly and willing to try to help.

I usually give people a hint rather than the answer unless they ask otherwise.

Charlene you are amazing! Just like everyone else, I appreciate your patience and clear way of explaining things. I am slowly getting this with all of your posts. Can you give me a hint from here?

Look at the blue box. The 4 has one filled square and needs three more. If the three squares were part of the 5, then the 5 would need two more filled squares. Since there are only two leftover squares in this scenario they must be filled in. And since the three filled squares complete the 4 the remaining squares for the 4 are blank. Next you can complete the 3 on the bottom row.
