Impossible grid-puzzle at 80,120 (surface)?

[Wolfenswan]

There's a grid puzzle at above location which I think has no solution:

Easiest to tell is by looking at the bottom "2 4" line: The two connected pieces have to be either in the top or second-to-top row. Which means the four connected dots always have to cover the two "1 2" rows on the right. To achieve the "2" a dot has to be placed to the left of the 4-line. This, however, is illegal, as according to the bottom row there can only be one dot in the second-to-last column.

You are right, it should be "4 2" and not "2 4"

[Wolfenswan]

That worked.

Found another that you can solve, but one viable solution isn't accepted:

The upper left group can be arranged in a slightly different way (the one that will work)

[Wolfenswan]

Yeah I figured it out eventualy, but it's a bit confusing as you usually don't assume there's more than one solution for this type of puzzles.

Yes, I'll probably have to modify it, thanks

On the off chance someone else arrives to this thread asking the same question (and my apologies for the necromancy). The numbers indicate how many selections there are (no more, no less) in the row or column they are near which are contiguous (in a line).

If there is a space in the numbers (so a row has a 1 3 for example) then that means there is a SPACE between the spot that has one selection and the one that has 3.

So a 1 3 could have an answer of X XXX. A 2 2 could be. XX XX. They can placed anywhere but usually you have to match the row and column requirements since they intersect. Here's an example of a grid, numbers, and a correct solution (I think) for it. It's rather difficult to make a grid on steam so hopefully this looks correct.

- -2 1 3 - -
+ - - - - - - +
| - X - X - - | 1 1
| - X X X- - | 3
| - - - -X -- | 1
+ - - - - - - +
