There is a 9 by 9 grid make up of 9 3*3 squares. Each row, column and box must have the numbers 1-9 exactly once. Today's was a tough one.

wtf do you do?

You have to fill in all the blanks.

So, we have a 3 in row C, box i) and in Row A box iii)
Therefore, there must be a 3 in Row B box ii), and there are only two spaces available Column D or F. But we already a 3 in Column D (Row D), therefore Row B Column F (B,F) is a 3.

Oh ok, I think I get it now. So in each group of 3 rows, the same number is in different sections, and in all 9 rows, it's in nine different spaces.

This is going to keep me hella entertained in lecture today. I like it.

Each column contains the numbers 1,2,3,4,5,6,7,8,9 once.
Each row contains the numbers 1,2,3,4,5,6,7,8,9 once.
Each 3*3 box contains the numbers 1,2,3,4,5,6,7,8,9 once.

There is an entire section (or two if you're unlucky) comprised of logic games/puzzles. I used to think things like this were fun, but practicing them for months under strict time constraints has conditioned me to cringe whenever I see anything similar.
