My mother can't play Uno

I have to give her a little credit (she had been drinking quite a bit) but my mother can't play Uno. http://en.wikipedia.org/wiki/UNO_(game) She says there's no strategy to the game but if the suit is blue and you don't have any blue cards, don't use your wild card to change the color to blue. And that being said, don't do it multiple times. Uno is a fun game but hysterical when you play it with her.
