How do I load a game into my plugin?

[vismodo]

I put this question as an issue already, but here it is again.

I'm new to Java and Spigot, so bear with me. I'm trying to make my plugin automatically connect a player to a game. I found that that can be done using joinToGame(player) on a game instance. I want to know how to retrieve the correct game instance using the arena's name. I don't know if I have phrased this properly, so I'm going to put what I want to do, in a line of code:

arena.joinToGame(player);

Thanks!
