Registering a Card Game Invention/Phone App/Smart Board Game

I have been using a warm-up spelling game for years on whiteboards and in one on one classes for years. It has been a hit with younger basic level students, and middle and junior high school students at both International and local elementary schools.

I have come up with a way to turn it card game, which of course can than be turned into an app for phones and be made to be used in schools on Smart Boards.

This game will make money. I am quite positive, especially in Asia (we all know why).

So, I guess my question is how to get the process started? The laws seem vague as to how register the game as an invention/creation.

If anyone has some legal knowledge/money I wouldn’t mind putting together a presentation to get some people interested.

Thanks
