UNO Teams!

UNO Teams is a new way to play the classic game! Players still match color, number and symbol but instead of every-man-for-himself, they team up in pairs of two and play together to win. Special cards and rules help teammates work together, but both players must get rid of all the cards in their hands to win. And remember, when you (or your partner!) are down to your last card, don't forget to yell 'UNO!'
