Board Game Arena

On the games in progress screen I can start new arena games with either "custom options" or "default options". How can I find out what these options are for a specific game. Also how can I modify them if possible.

Thanks in advance. BTW I'm on mobile if it matters.

You can't change many options for Arena play - mostly just game speed, and you can also limit the reputation of your opponents. If you're going from the game page, options are where they normally are. If you're on the Play Now page, each game has a cog that shows the settings (each game has individual settings). It shows you all the normal game settings too, but you can't adjust these for Arena play - there is also the ability to define how it should do matching (near my level, far from my level, etc.), which I don't think exists in the game page interface.
