The whole thing?! I may have been test-solving with my n00b hat on.

Yes, the whole thing. It took a lot of scribbling on another sheet of paper, but I managed it. I'm waiting on a friend to try it to be sure I didn't assume the ability to solve something that wasn't actually there, though.

Me too, I came up with a possible answer on the 5x5 box number 3. Not sure if it is the correct one, though. :D

Is it entirely solvable on its own, or does it require any hints from over in box 1?
Erik07 • 12/05/13 7:26 pm
For me, I just needed the 18, 5, and 6 on the third row to eliminate some possible answers.
I haven't written anything on box 1 yet. :D
Not sure if Trisana did a different approach, though.

I didn't have any hints from day 1; the only external hints I used were the fact that the center box of each grid is the day it'll be posted on...

Yup, I got an answer here after checking a moderately-sized list of cases, using only the given center cells in the rest of the grid.

There's some really fun logic in this grid that appears to have let me solve it without needing information other than the pattern that the day's number is the middle square of the grid. :D
