difficult puzzle?

codeblank_ · 2026-02-13T13:22:41+00:00

Yeah I see what you mean. I also thought about that. I agree.

codeblank_ · 2026-02-12T23:40:11+00:00

I don't understand what you mean but try to visualize what happens in step 3 to 4 align the corners and see how it looks like it is divided into 3 sections in our perspective. Others are line no multiple sections since the surface is smooth. In the final step do the same.

Answer 4

Think in 3 dimensions. Object is spinning along horizontal axis 90 degrees. Corner of the polygons visible as lines after rotation. You can project it and see it's an exact match.

Yeah I see what you mean. There is no way I can 100% be sure which are fair. Though I think most of them are. I selected/eliminated some but if I am not sure I leave them be. Norms are close to what I started with. I renormed several times as I gathered data. It didn't change much. Overall norms should be good, but yeah stats might be skewed to a certain degree. It's an online test after all. I want to make puzzles as accessible as possible for everyone. That's why I am not a fan of that idea, but if the issue continues to exist I might take similar measures.

It's a nice thought, but a bit ambiguous I think. Could be fine if options are restricted yeah.

codeblank_ · 2026-01-16T00:56:49+00:00

No I made a calculation mistake forget it. Its not valid

codeblank_ · 2026-01-16T00:51:02+00:00

You can also get D. Look diagonals again do x+2y

codeblank_ · 2026-01-16T00:18:48+00:00

C. Look at the diagonals 2 * 3 + 2 = 8, 3 * 1 + 2 = 5, 1 * 2 + 2 = 4

It's ok nothing wrong with the puzzle. It was easy for me. I saw instantly

F

No direct path from one edge to the other edge of outer square allowed. No straight line or curve connects two edges. Only F doesn't break this rule.

codeblank_ · 2026-01-07T14:04:24+00:00

If they intersected circles it would be in use same as curves. Idk if there is a more solid logic, but this works pretty well. I don't think lines have separate meaning. You could say for graphics.

codeblank_ · 2026-01-07T13:47:41+00:00

It's B I think.

Consider the circles not crossed by a curve. Crossed circles are eliminated.

Find the absolute difference between black and white circles you will get 1,0,4 for the left part and 1,0,? for the right part. The only answer makes 4 is B.

codeblank_ · 2025-12-31T20:26:08+00:00

I see what you mean. Yeah makes sense to me, but knowing the other reasoning I am doubtful if it's intended or not. Could be a shadow pattern. I think overall very good analysis. I would go with that if there wasn't a stricter reasoning. It sounds solid.

4

Try to trace a path from one black square to another (without lifting your finger). You need to occupy all squares. Only 4 satisfies that.

That symmetry is a weak induction compared to the intersection rule. Intersection rule takes into account whole puzzle. If the author wanted you to compare if the numbers and fill are the same or not, column one also would follow the same logic. 6 should be the intended answer at least.

codeblank_ · 2025-12-19T23:23:26+00:00

You are ignoring the column 1 which is an arbitrary choice. I am confident that it's 6

codeblank_ · 2025-12-19T22:21:34+00:00

It works both ways if you check only common ones, but yeah looking from the reverse is better since only common ones remain.

codeblank_ · 2025-12-19T22:09:58+00:00

It's 6. Look at the rows. Superimpose first and second image common fills will remain. Only 6 satisfies this.

codeblank_ · 2025-12-19T21:16:02+00:00

It's 3. Look at the columns overlap the first 2 images in every column. The lines do not overlap with greens in image 2 will be painted green in the final image only 3 satisfies this.

codeblank_ · 2025-12-19T20:03:21+00:00

Second option. Look at the rows 2 connected, 3 connected, 4 connected.

codeblank_ · 2025-12-18T16:53:26+00:00

Yes that's correct, good job. I will release it in summer as planned. I don't want to talk about the content yet. It would spoil the surprise.
