Im having a 13th birthday party but i need one more game .. any suggestions?

You could do sploosh. You get one ball and a few friends. Number each person from 1- how many people you have. Then onw person takes the ball and says a number. The person who has that number catches the and then says sploosh. Everybody has to run while the person catches the ball. When the person catches the ball everybody stops. The person takes three steps and tries to hit somebody. If they get hit they get to throw the ball next. I hope this helps a lot.
