UNO has a new best friend DOS! In this fun card game two is more important than one and number matching is king! Just like UNO DOS involves a race to be the first to get rid of your cards. 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! The game includes a 108-card deck plus instructions. For 2 to 4 players. Ages 7 and older. Colors and decorations may vary.
