Board Game Arena

I've played once with a player that successfully activated all extensions in Carcassonne. That was awesome. I would like to play with the extensions again but I don't know how, every game I started is basic. Thanks.

To do this, you need to be the one whose creates the table and sets options on it. On the ""Play Now" screen, there are three big buttons at the top - on the right, choose "Manual". Then find Carcasonne in your games list, and click "Play Now" - it should open up a list of existing tables with one at the top saying "Create a new table". If you click the "Create" button there, you get a new screen and on the left are a list of pop-up menus for each expansion you can change every No to Yes. Finally, you can "Open the table to other players" so that other people can join and play.
