You should tell what kind of minigames that you just found. I've found 2 minigames on chaos-project forums, dunno if it the same as the you have.
EDIT : The Rules is really confusing... >.<
Advertising other forums is not permitted in posts, social groups, blog entries, visitor messages, or private messages.
The community prohibits unsolicited advertising of forums. The only space where you are permitted to advertise is your signature. Members who join and send forum links to other members over the private message system will be immediately banned on the notion of joining with the intention of advertising their forum. You are permitted to link to threads and posts of another forum when it may helpful and contributive to the thread. Linking to other web sites is permitted anywhere in the community, but blatantly advertising web sites is not permitted. (It is left to the discretion of the community staff to decide whether a link to a website or forum may be considered advertising. Unacceptable forms of linking may be edited without question.)
