If you like UNO, you'll love DOS! In this fun game, two is more important than one. To start, there are two piles in the middle of the participants, and on each player’s turn they can play on both piles with either one or two cards. In a fun twist, if a player has two cards that add up to the number of the card in the centre pile, they are able to put down both cards. You score points by being the first to get rid of all the cards in your hand, and action cards let you make things more difficult for your opponents.​
