Everyone Loves to Play Free Casual Games

I recently read an article about how to increase traffic to a website and learned a lot.  There were a few really good ideas that I am working on implementing right away.  One of the methods suggested placing free casual games on the pages of the site.  This works two ways; first you get the word out about the free game thats offer and second, when people do arrive at your site they tend to stay longer.  I am trying to find someone that can code the pages so that visitors scores will be stored so they will be inclined to visit often to keep their standings.
