Everything is possible, though if you have to ask this kind of a question here, you are far from doing it.

Browser game hacking is very possible, harder than client hacking in my opinion but it's not impossible. I would look into but you need to be more specific and that link you have isn't an actual url, but like I said it's very possible but it just depends on what you want to do nothing in hacking is impossible but some stuff is much harder and could be considered impossible.
