Mattel - Ref: HNN01 - Uno Dos Second Edition, Family Card Game With New Rules For Game Evenings, Travel, Camping And Parties, Aperitif Game, Children's Toy, From 3 Years

As with the UNO® and DOS card games, DOS Second Edition players attempt to get rid of all their cards. 
But new cards and rules make the game even more fun. 
There are TWO discard piles and all "2" cards in the game are "Joker DOS" cards, meaning players choose the color of the "2" card when playing one. 
The game contains the same Action cards as the classic version, but also a “Joker Play 2” card which requires the next player to place at least two cards during their turn. 
If he can't, he will have to draw two. 
Twice as much action in preparation for game nights with family or friends. 
Colors and decorations may vary. -The DOS Second Edition card game offers new cards and new rules for even more twists and turns during game nights! -To get rid of their cards, players can place them on one of TWO discard piles, or even on both! -All “2” cards are “Joker DOS” cards, meaning players choose the color of the card. -The “Joker Play 2” card requires the next player to place at least two cards during their turn, and if they cannot, they will have to draw two. -If a player places two Action cards during their turn, the next player must perform EACH of the actions indicated!
