You used ‘1’ twice in a column.
You can’t put the same number twice in a column or row.

Ah, thanks for that.
Edit, I'm just an idiot, it literally says so on the page.

I found one that's genuinely bugged.

Seed 631,315 produces this:
Code: Select all
    | 13 | 27 | 11 |  3
----+----+----+----+----
 16 |XXXX|    |    |XXXX
----+----+----+----+----
 18 |    |    |    |
----+----+----+----+----
 10 |    |    |    |
----+----+----+----+----
 10 |XXXX|    |    |XXXX
The top row has to make 16 with just two numbers, which can only by 9+7. However, neither order of putting these will allow the third column to be completed, because the lowest you can get is 7+3+2+1=13, which is already more than 11.

EDIT: Seed 226,057 also looks iffy to me.
Code: Select all
    |  7 | 13 | 29 | 17
----+----+----+----+----
  4 |XXXX|    |    |XXXX
----+----+----+----+----
 22 |    |    |    |
----+----+----+----+----
 30 |    |    |    |
----+----+----+----+----
 10 |XXXX|    |    |XXXX
The first row can't contain anything higher than a 3 (1+3=4), but that makes the third column impossible, since the highest it can get is 9+8+7+3=27, less than 29.

EDIT 2: Etc. I've seen a bunch of these, and so far all of the unsolvable puzzles I've gotten have been ones where the four corner squares are the blanked-out ones.

I'm having a problem, how do you do these? I am questioning on how to do these grids.
