Fairly hard puzzle.

Ok, start by drawing a tic-tac-toe board on a piece of paper. Now using numbers 1 to 9 fill in the board. You can only use each number once. Now the hard part, make each row (horizontal, vertical and diagonal) add up to 15. When you are done, every row has to add to 15, no exceptions.

For example:

_ 3 _|_ 7 _|_ 5 _
_ x _|_ x _|_ x _
_ x _|_ x _|_ x _

That top row adds to 15.

_ 3 _|_ x _|_ x _
_ x _|_ 8 _|_ x _
_ x _|_ x _|_ 4 _

That diagonal row adds to 15.

It took me about 15 minutes before i figured it out.

Have fun,

PS. If you figure it out, dont post it until a few days have passed, I'd like to give as many people a chance to try it if they want to.
