Uno: strategy?

[kingofmirrors]

Is there enough strategy in the game of Uno to make one player significantly better than his competitors? It seems like such a simple game that the cards you draw should pretty much determine who wins, but I've been consistenly winning my Uno games (yes, we still play Uno) while employing basic strategies like getting rid of duplicate numbers, keeping as many colors as possible, remembering what colors people don't have, etc. And it's not like I'm playing with a bunch of 8 year olds... but even if I was would it matter?

All luck and no skill or what?
