On a ski trip with friends we spontaneously turned a game of Uno into a Mao drinking game.

The rules were: •• Picture cards worth 10pts, black cards 50pts, number cards = n points •• At game end, 2 players with most points drink •• +4 can stack on +2, and vice-versa if color is right •• Uno Uno doesn't win unless no cards can be stacked anymore •• No deck shuffling

This resulted in the most fun and long Uno games, as people would keep the risky + cards till the end to stack on the Uno Uno player and keep him in the game. The no-deck-shuffling added an element of card-counting to the game as the discarded cards would be added to the bottom of the deck when no cards were left to draw.
