The best way to play the game is to:
-Watch and listen to the entire video without interruption and try to understand the dialog. If you don't understand, don't worry. Just do your best!
-Watch and listen to the video one more time and try to fill in the blanks. Don't worry about making mistakes. Again, just try your best.
-When you are done with the exercise, click 'Finish' to view your results and check them against the video to understand any mistakes and look up words you didn't understand in the dictionary.
-Remember you can pause the video or you can go backwards or forward.
-If you register first you will be able to save your score.
