How can I get a patent/Copyright for the puzzle game I invented?

I have invented a new puzzle game which I have able to play on paper.

However, I want to create a mobile app/web app to let other users play like other below games.

Example: Threes, 2048

But being not a good UI developer myself, I was thinking to contact other UI developer. But if I tell the idea behind my game to them, they could ignore me and launch the game themselves.

How can i get copyright access for the puzzle game I invented?

If the platform for asking this question is wrong, kindly tell me where I can ask this question.
