Sag, that's quite a stretch. For instance, you can get a patent on the mechaincs (meaning MECHANICAL BITS) in an Attacktix game or something, but you can't patent the "concepts" of how a game is played very easily.
WICE: Attacktix is a patented game:

Patents are generally reserved for devices or inventions. You can patent a physical object, or an intellectual property such as a novel algorithm for compressing data in an unique way. It would be very hard to get a patent on, say, the die-rolling combat mechanic in Risk or something.
BUT, it's not unheard of:

Copyrights are for original works of art, literature, music...that sort of thing.
Here's a quick synopsis:

Also, Copyrights exist naturally from the moment something is created. You can register them with the copyright authority in your country, but in the US, the moment you write something on a piece of paper, you are the sole owner (unless you're doing it in the course of your work for a company, in which case that's stickier).
Patents can be applied for, it takes YEARS to get one, and you cannot patent something that anyone knows about publicly. The moment you tell ANYONE PUBLICLY about your invention, it is immediately disqualified for a patent, in almost all cases. SO, if you want to patent something and need to talk to someone about it, get an NDA or other confidentiality agreement in place or you limit your legal protections.
