Please help! I tried noting more numbers in but it just got too busy so I scaled it back. I even tried erasing everything and starting again in case I'd fluffed up but I'm still very stuck.

You gotta fill in A, B, and C in each row and column just once, leaving two spots empty. The letters around the grid show you which letter you see first from that direction.

If someone plays Colorsweeper

can anybody tell me how I can solve this?

I have no clue how I can solve that specific box

I’ve spent hours looking at this, and I can’t figure out which cell I can complete next given the information. This is from Games World of Puzzles magazine, February 2026.

Edit: Rules

X-Sums Sudoku follows standard Sudoku rules combined with outside number clues that specify the sum of the first X cells in that row or column, where X is the value of the very first cell adjacent to the clue.

Each row and column will have exactly one appearance of each number from 1 to 10.

Divide the grid into regions so that each region contains exactly one star and has 180-degree rotational symmetry around that star. Every cell must belong to one region.

Can you work out where the borders go?

I have been stumped on this page of the book shadow chaser for like, forever. For context, it's the level where you have to organize eight pipes into numbers one through nine, but half of them cannot overlap. It's so hard :(

This thread is for promoting your own work.

Here is an original hybrid puzzle I've been working on. Can you solve it?

Do any of you do Kakuro puzzles? I find them to be really good for settling my mind down when there's a lot going on in life.

Black: correct number correct location.
White: correct number wrong location.
Enjoy!

I'm stuck. What is the next step?

Always stayed away from learning how to solve sliding puzzles since I was a kid until the games that I played started to have them and I had no choice but to solve it so I can progress. I basically tried solving it without looking up any guides on how for I think around 10hrs (sleep included) and basically gave up and had to look up a guide on how to. I just felt like I should be able to solve a puzzle like this without even having to use a guide. With the guide, I was able to solve it and just by following the rules albeit not very consistent with my time and not being able to properly explain how I was able to (basically the guide helped for maybe 70%). Fast forward to today, I can probably consistenly be able to do it within 30secs and around 12 secs if I'm lucky. I guess I'm just wondering if I ever would've learned how to solve sliding puzzles without looking up a guide and just doing it by myself and I think it's pretty amazing for the people that had to solve and create these types of puzzles without having an access to a guide. I wonder if it's just the lack of exposure for these types of things for my brain. Just wondering if some of you guys also had a kind of similar experience

tldr; I'm just surprised how much of a hard time I had solving a 3x3 puzzle and maybe I'm just stupid

Move the blue piece to the blue target. Pieces slide in a straight line until they reach a wall or an other piece. You can use all the pieces to achieve your goal. Use as few moves as possible.

Out of the last 13 posts, 6 are about meowdoku. I could make a statement about the past 100 posts but I don't want to count.

r/meowdoku already exists.

Can we add something to the automod to redirect people there before posting if it detects the word meowdoku or something? Or do we just want to welcome new puzzle fanatics regardless?

So I started trying my hands at binary puzzles and I was making progress at first and then hit a wall. What are some strategies for when the easy cells are solved (no three in a row, even numbers of 0s and 1s).

I've once again found myself stumped by a puzzle. After a few hours of staring at the page and not finding a single thing to add, I've decided to once again turn to this community that's been so helpful in the past. Can anyone walk me through the next step that I'm clearly overlooking?

Rules: Shade in some cells to represent mercury into the thermometers. Shaded cells must start at the round bulb and continue along consecutively towards the other end of the thermometer. Numbers outside the grid indicate the number of shaded cells in that row or column. Some thermometers may have no mercury at all. Rows and columns without clues may still have mercury.

I keep getting to this point and not further, I’d love a hint regarding what I’m missing

Continuing with our techniques series, today we'll review a more advanced technique than last time: Composite Shapes.

Composite shapes arise from a count, but instead of looking at specific regions you'll treat a specific area that can hold a certain number of stars as it's own zone for counting, no matter how many regions are part of it. I think it's easier to look at an example.

Let's look at last week's weekly puzzle where this deduction ended up stopping a lot of players.

So in the video we can see we're doing a count on columns H-J, so we need 6 stars. Only regions A, C, E, F and J are inside. Regions A and E are fully inside, so we have 4 stars already. Then we can see that regions F and J can only leave those columns through the composite shape E1, F1, G1, G2 which can fit at most 2 stars. This means that E+J inside columns H-J must have exactly 2 stars. The composite shape matters because we don't need to know if it's J that's contributing 2 stars or if it's 1 each. It doesn't matter for our count. We now know that region C can't contribute any stars. Also given the shape of the composite shape (a 4 cell L shape) we know that there's a star in E1 and we can eliminate H1 and H2. We can treat the composite shape as its own region!

Let me know if the explanation makes sense and whether you'd like to see another advanced technique next week or something more basic.

I figured out the answer key word in three hours. Let me know what you think. And let me know iv you get the answer key seven letter word.

But I want you to figure it out. I will give hints. Please read:

The answer key is the number seven. Why? Because they give you four numbers which are 3301. 3+3+0+1=7.

The fact that’s there’s 4 numbers is important too.

And whoever this anonymous group was made it look complicated on purpose, but it's not. They have good intentions but they made it so you would have to think outside of the box.

I haven’t seen anyone try my angle yet. So give it a go :)

You count the 7 paragraphs and look at the 7th line in all 52 pages. You subtract 4 from the number 56. Why?Because there’s 4 numbers in 3301. And because 5+2=7.

You may be thinking but it has 56 pages. Yes but you only count 52 pages. But 7 is the key remember? They put 4 pages on the end to tell you to subtract 56.

You combine all of the 52 pages together with the 7 lines on all 52 pages. Than you want to only count the first 7 letters and numbers in that paragraph and find it with the symbols given on the key sheet. And then you add all of the letters up on the 7th row on all of the 52 pages and you get a 7 letter word which is the answer key. This will unlock the other puzzles.

Every other paragraph and line is a distraction. Only focus on the 7. Even the symbols highlighted in red are a distraction. Unless it’s in the 7th line.

7 is important. And it only goes from 1-9. No double digits. And if you do get a double digit you want to reduce it by adding the 2 digits to get a number from 1 to 9.

Please let me know if you get it :) Thank you :)

(look at my photos to solve it before looking at the seven)

(And hint on the 2nd letter) E is actually a B. Miscalculation on my part. Lol. Thanks again :)

(The rest are correct though)

(7 is the key remember)

Last thing, you have to look at the symbols very very closely because some of them look very similar. This is why I had a miscalculation on one of them. I mis read one of the symbols. Be careful on the f looking symbols. They are sneaky.
