The best and worst house rule is stacking penalties. Player One plays a Draw 2. Instead of drawing, Player Two plays a Draw 2. Player Three does the same. Player 4 has no Draw 2 cards, and so must draw six cards.
It's also awesome to play two-player with skip and reverse cards. If you get a lot in your hand, you can shed most of them in a single turn. "Skip you, back to me... skip you... skip you... reverse, back to me... reverse... reverse... skip... reverse... skip... skip, and Uno, by the way... and finish off with a Wild Draw Four."
