A standard UNO deck consists of 108 cards. These include:
- 25 cards of each color (red, blue, green, and yellow), with each color having one zero card and two each of cards numbered 1 through 9.
- Action cards in each color: two Draw Two cards, two Reverse cards, and two Skip cards.
- 4 Wild cards and 4 Wild Draw Four cards, which are black and can be played at any time to change the color or force the next player to draw cards.
Some newer or themed versions of UNO may have 112 cards, which include additional special or customizable wild cards and sometimes blank cards used for house rules or replacements
. In summary, the classic UNO deck has 108 cards, but some recent editions contain 112 cards.
