Using the name
Thank you for writing about the game. A trademark is a brand name, so it works best as an adjective next to what it names:
- Write “the HAPPINESS® card game,” and mark the first prominent mention with ®.
- Please don’t use HAPPINESS as the name of another card game or game product, or in a way that suggests a connection that isn’t there.
