Skip card

A skip card is a card found in the standard Uno deck that comes in all of the four colors: Red, Blue, Green, and Yellow. When this card is played, the next player in line to play after this card loses his or her turn.

House Rules
If this card is stacked, the number of skip cards will tell the number of players that are skipped. For example, if two skip cards were played, the next two players in line would be skipped. However, some people say that you can't skip yourself, which would mean that the person in line to play after the person who played the card would be skipped instead of the original person.
