How to block access to games on VKontakte / Odnoklassniki sites?

Question

Computer networks

I need to block access to VKontakte games (you can to certain or to the entire branch of games). Do not offer a hosts file, because it allows you to block the entire site, and not a specific link. I also tried blocking through the antivirus nod32, but this also did not help.
PS I use a browser from Yandex.
