Sneha (my sister in law) asked me to solve this puzzle. If you sum up any side, the total always comes to 65. The puzzle is to find out the pattern in this. A pattern that you can extend to any odd dimension matrix. This one is 5x5, the logic of placing the numbers will work in 7x7 or 9x9 and so on...
She took an hour to solve it, and after a week of keeping the puzzle in my bag and not solving it, I simply asked her for the solution!
Can you figure it out?
And can your sister in law figure it out? ;-)

Start with the middle square of the right hand side. Keep going right and down, wrapping when you hit the right edge or bottom. If the next square is filled, move one square left and continue.
