Hey guys, I took a really long time on mine, a little over 2 hours. I did it as fast as I could, I just had some trouble with finding the right answers to questions.
Here are my recommendations to whoever does the other two.
1. Take your time finding answers. It's far more important to be right than fast, because 1 mistake could send us to tribal.
2. Once you have all your answers, add up the placements, and divide by 3. That will tell you what the rows and columns add up to. If you don't get an integer, one of your answers is wrong.
3. You can put your first number anywhere and still have this be solvable. I recommend putting the largest number in a corner. For example, if your numbers are 1 through 9, the sum is 45, so each row adds up to 15.
If you put 9 in the corner, you know that the rest of the numbers in that row add up to 6, (1 and 5 or 2 and 4), and the same with the column. Because the first number you place in a row or column doesn't mess with anything, you can just put
9 1 5
2 . . .
4 . . .
Now you see that the 1 column needs to add up to 15, so the 8 and 6 goes in that column, and the 3 and 7 are left for the column with the 5. Since the 8 and 7 can't be in the same row since they add up to 15, we know that the 8 and 3 must be in the same row. Sinc 15-8-3=4, we know that the 8 and 3 are in the same row with 4.
9 1 5
2 6 7
4 8 3
Is the solution. Hooray!
Yeah, but basically look at your small numbers and large numbers first. They reduce your number of choices pretty quickly. Good Luck! This is an important one. Just take your time and double check your answers.
