- A standard deck of cards consists of 52 cards, plus two "jokers." An UNO deck contains 108 cards total.
- Cards in an UNO deck range from 0 to 9, with eight of each number except the 0 card. There are also eight "Skip" cards, "Reverse" cards and "Draw Two" cards, plus four "Wild" cards and four "Wild Draw Four" cards. Cards in a standard deck range from ace to 10, followed by three face cards of jack, queen and king in ascending order. The ace in a standard deck may also function as the highest card in the deck. There are four cards of each value.
- With the exception of the "Wild" and "Wild Draw Four" cards, which come in black, all cards in an UNO deck come in four colors: red, green, blue and yellow. Each of these cards come in two of each color. All cards (except the jokers) in a standard deck come in four suits: black spades, black clubs, red hearts and red diamonds.
- Of course, an UNO card deck is meant solely for playing the popular Mattel card game. A standard card deck can be used for many games, from go fish to poker.
