Really easy. You should immediately realize that 9,8, and 7 have to go on the diagonal.

Start off by ensuring that no two numbers of 9,8, and 7 share a row, column, or diagonal. After that, it is easy.

Always start with placing 5 in the center; even number in the each corner; and odd number in the remaining box
