What is a role his or her game?

Please provide me with more context! I need to know what "his or her game" refers to in order to understand what role you're asking about.

For example:

* Is it a board game? If so, what is the name of the game?

* Is it a video game? If so, what is the name of the game and what character are you referring to?

* Is it a social game? If so, what is the specific scenario or interaction you're asking about?

Once you provide more information, I can help you determine the role in the game!
