games flash

I am working on a blog that is related to playing games online. I am unable to add script in the post to play games online from miniclip. But the coding is not working and as i am using free wordpress blog i have no access to install plugins. How do i add these games to my blog?

I run a game website (amazingslacker) but I'm not foolish enough to believe that I can compete with websites like addicting games and miniclip. That's not what I'm aiming for. About 60% of my traffic comes from us with the rest international. My question is how can I improve my traffic...
