Two is better than one with this twist of Uno.
To start, there are two discard piles between the players. On each player's turn they can discard on either pile with either one or two cards, so if a player has two cards that add up to the number of a card in the center pile, they are able to put down both cards. When you're down to two cards, don't forget to yell "dos!" the first person to 200 points is the winner!
Ages 7+. 2-4 players.
