The option for Lists to use is second from the bottom.

Click on where it says Multiword Phrases and a pop-up list will appear with all of the current Thematic lists.

As you move the mouse up and down on the list it will highlight the list you are hovering over.

Click on the list you'd like.

On an iPad or other device it may appear like this:

The Wrong guesses allowed defaults to 11 guesses. This is a number that seems to work well for most people.

The Points to win defaults to 6 Points. 4 points is a quicker game. 10 or 15 is a longer game.
