In the game of Uno, there are Draw Two cards with a +2 sign on them, when a player plays a Draw Two card, the next person must draw two cards and skip their turn. This card can only be played on a matching color or another Draw Two card and if a Draw Two card is used at the opening of the play, the first player must draw two cards.
UNO Draw 2 Card Rules
Additionally, there is a wild Draw Two card which also forces the next player to draw two cards from the draw pile and skip their turn. After playing a Draw Two card, you can select the color of card that continues play. For example, if the top card of the discard pile is a red 6, you can play a wild Draw Two card and specify the color as “yellow.” Then, the next player has to draw two cards and miss their turn, and the following player has to play a yellow card or another wild card.
In a variation of the game, if a player lays down a Draw 2 card, the next player can either draw two cards or counter the initial draw card with their own Draw 2 card. If a Draw 2 card is “stacked,” the next player must draw four cards or play another Draw 2 card. If that player has a draw card, the next player will draw six cards.
According to the official UNO Twitter account, stacking is against the rules to stack “draw 2” cards. However, stacking forces a player to play a Draw Two or Draw Four if the player has it in their hand in a stacking situation.
