First of all, lately there is a bug (?) - the game freezes and it starts again resulting in losing every freaking game. Second, there are three kind of players in there: the ones that don't know how to play UNO, the ones that are so dumb they can't play smartly, and the ones that all they care about is to throw +4 cards. Noone plays strategically, and it's frustrating. Yes this game is addictive but it gets annoying with lousy players and the coin culture.
