Just like UNO and DOS card games, DOS Second Edition players race to get rid of their cards but with updated cards and rules designed to make the game even more fun for game nights. There are TWO discard piles, and every number '2' card in the deck is a 'Wild DOS Card,' meaning it can be any colour '2' a player wants. Action cards include the classics, plus a 'Wild Play Two' card that forces the next player to play at least two cards on their turn, and if they can't, they have to draw two cards. , , It's twice the action and tons more fun for friends and families on game night. Colors and decorations may vary.
