This is potentially patentable, depending on the implementation. The Asker did not say it was just an idea. The Asker may have it all fleshed out in an enabling manner sufficient for patent application. Or it might be a done as a video game and, jointly with a programmer, should be patentable subject matter. Copyrights and trademarks might also apply to it, as you noted.

I disagree this Asker does not need an attorney when doing a copyright application on this for $35, as the copyright application might cost valuable patent rights by publishing the rules at the Library of Congress for all to see.
