How Many Cards Are in an UNO Deck?

UNO is one of the most iconic card games of the last century, known for its bold colors, wild gameplay, and that satisfying moment when you can finally yell “UNO!” But for anyone curious about the specifics—particularly the makeup of the deck—you might wonder: how many cards are actually in an official UNO deck?

Here’s a full breakdown of what you’ll find inside the box.

‍

Standard UNO Deck Size

A standard, modern UNO deck contains 108 cards in total. This number has remained consistent for decades, with only minor changes depending on themed editions or special rulesets. These 108 cards are divided into several categories, including numbered cards, action cards, and wild cards.

The design of the deck is meant to strike a balance between strategy and luck, making it playable for all ages and skill levels.

What’s Actually in the Deck?

The majority of cards in an UNO deck are numbered cards in four distinct colors: red, yellow, green, and blue. Each color includes cards numbered 0 through 9, but not all of them appear in equal amounts.

Here’s how it breaks down:

• Each color has one zero card
• Each color has two of each card from 1 through 9

In addition to the numbered cards, each color also includes action cards such as Draw Two, Reverse, and Skip. There are two of each action card per color, adding more twists to the gameplay.

Then there are the wild cards, which don’t belong to any specific color:

• 4 Wild cards (you choose the next color)
• 4 Wild Draw Four cards (change color + force another player to draw)

Together, these make up the full 108-card count.

Do Special Editions Have More Cards?

Yes, certain editions of UNO do alter the deck size slightly. Some themed versions include additional cards with custom rules—such as swap hands, custom wilds, or blank cards that players can write on. These extras can push the total number slightly beyond 108, but the base structure usually remains unchanged.

Digital versions and mobile app editions of UNO may also include special modes or expanded card types not found in the physical deck. However, for classic tabletop play, 108 is the expected total.

Why the Deck Is Built This Way

The distribution of cards in an UNO deck is intentional. By limiting some numbers and duplicating others, the game encourages strategic play while keeping the rounds fast-paced. The inclusion of multiple action cards and wilds ensures no two games feel exactly the same.

Even the single zero per color plays a role—its scarcity adds weight to when and how it’s used. The 108-card design strikes a careful balance between chaos and control, which is part of why UNO remains so replayable.

Final Thoughts

A standard UNO deck includes 108 cards, carefully organized across four colors, multiple actions, and wildcard mechanics. While special editions may add a few extra twists, the core deck has remained largely the same for over 50 years.
