Choose the the settings you want to test yourself on and click Start a New Game. You will be presented with a list of 5 pictures and either 5 or 10 names (depending on your game settings). Put the letter of one of the names in the box next to each picture. When you have put all the letters in the boxes, click the Submit button. The game will tell you how many you got right and track how many guesses it takes you. Your goal, of course, is to get it in as few guesses as possible. Once you get them all right, you will be able to click on the names to find out more about those individuals (links will open a new window).

This game doesn't keep any high scores, since its fairly easy to look up the names in the OP. The point is to test your knowledge of the people in the kingdom and learn about arms and people that you may not be familiar with.
