You can do this in paper, the challenge here is to go over all the 9 dots with 4 and only 4 straight lines without going twice over the same dot, the catch being that when you change from one line to another you can't lift your pencil, meaning that after you start, the next straight line must start where the previous one ended, to the maximum of 4 straight lines. Go!
