UNO Number Cards Explained

Number cards make up the bulk of an UNO deck and drive its most basic action: matching a card by colour or by digit to shed your hand. They rarely get the attention that Skips, Reverses and Wilds attract, yet they decide most rounds simply because there are so many of them. This guide sets out exactly how many numbered cards are in the deck, what each one is worth when the round ends, how matching by number works, and a few honest, beginner-friendly tips for using them well.

How Many Number Cards Are in the Deck

A standard UNO deck holds 108 cards, and 76 of them are number cards. Each of the four colours — red, blue, green and yellow — contains one 0 and two each of the digits 1 through 9. That works out to 19 numbered cards per colour, or 76 across the whole deck. The remaining 32 cards are the 24 action cards (Skip, Reverse and Draw Two, two of each per colour) and the 8 Wild cards.

Because number cards account for roughly seven in ten cards, they are what you will hold and play most often. If you want the full picture of every card type and its value, our guide to UNO card values lays out the complete deck.

Why Two of Each Digit Matters

Since every colour has two copies of each digit from 1 to 9, you will often hold matching pairs — for example a blue 4 and a red 4. A pair like this lets you change the active colour without spending a Wild: play one 4 to match the current colour or number, then the other 4 later to pivot the game toward the colour you hold most of.

The Rare Zero Card

The 0 is the outlier of the number set. There is only one 0 per colour, so just four exist in the entire deck — half as many as any other digit, which each appear eight times. That scarcity makes a 0 harder to shed by number, because the chance of a matching 0 turning up is lower. On the plus side, it is the safest card to be caught holding: at zero points, it adds nothing to an opponent’s score if they go out first.

The 7-0 House Rule

Official Mattel rules treat the 0 as an ordinary number. Many households, though, play the popular “7-0” variant: playing a 0 makes every player pass their whole hand to the next player in the current direction of play, while a 7 lets the player swap hands with someone. It is not in the official rulebook, so agree on it before you deal. You can read more variants in our roundup of UNO house rules.

What Number Cards Score

UNO is usually played to 500 points. When a player empties their hand, they collect points from the cards everyone else is still holding, and number cards are the simplest to count: each is worth its face value. A yellow 9 is nine points, a green 2 is two points, and a 0 is nothing at all. That is far less than the 20 points a Skip, Reverse or Draw Two carries, or the 50 points on a Wild or Wild Draw Four — but a fistful of 7s, 8s and 9s adds up quickly. For the full method, see how scoring works in UNO.

Keeping Your Point Liability Low

Because you never know when a round will end, it is generally sensible to play your high digits early when a legal match allows. Being caught with three 9s hands 27 points to the winner. Ending a round holding low cards — 0s, 1s and 2s — keeps the damage small if someone else goes out first.

Matching by Number vs Matching by Colour

On your turn you may play a card that matches the top of the discard pile by either its colour or its number. Matching by number is the main way to steer the game’s colour toward your hand. If the pile shows a green 5 but you are short on green, a blue 5 both makes a legal play and switches the active colour to blue. New players often forget this option and draw unnecessarily.

• Colour match: keeps the current colour in play.
• Number match: changes the active colour to that of the card you played.
• Practical tip: use a number match to bridge into whichever colour you hold most of.

A Simple Bridging Example

Say the top card is a red 8 and you hold a yellow 8 plus several other yellow cards. Playing the yellow 8 matches by number and turns the game yellow, letting you follow up with the rest of your yellow run on later turns.

How Likely You Are to Draw a Number

In a freshly shuffled full deck, about 70% of the cards are numbers, so most draws hand you a numbered card. The table below shows the split. Keep in mind this is only exact at the start; as cards leave the deck the odds shift, so treat it as a rough guide rather than a live probability.

Watching the Discard Pile

Casually noting which numbers have already been played can help. If both blue 6s are gone, you know a 6 is no longer an easy route to change colour, which can inform whether you hold or spend a pivot card.

Number Cards After Action and Wild Cards

Number cards cannot cancel or defend against action cards under official rules — they simply follow them. After a Skip or Reverse, the next player still needs to match the current colour or number. After a Wild, the player who set the new colour forces the next player to produce a card of that colour, which is very often a number. If you want to understand the cards that push numbers around, see our guide to UNO Wild card rules.

Number Cards in Two-Player Games

Head-to-head, action cards gain value because they can hand you an extra turn, but numbers are still how most one-on-one games are won. With a single opponent to read, it is easier to guess which colours they lack and to time a number match that leaves them unable to follow. Numbers remain the quiet workhorses that carry you toward your last card.

Playing Your Last Number Card and Calling UNO

Your final play is very often a number, because numbers have no side effect — they do not skip anyone or change direction. That makes them slightly riskier at the finish line: when you play your second-to-last card and reach one card in hand, you must call “UNO”, and because a number does not skip the next player, they have an immediate chance to catch you. If a player is caught not calling UNO before the next player takes their turn, the penalty is drawing two cards. More detail is in our explainer on what happens if you forget to say UNO.

Getting Started With Number Cards

To begin a game the dealer flips the top card of the draw pile to start the discard pile. If that card is a number, play is clean: the first player simply matches it by colour or digit and the game proceeds with no penalty or direction change. This is the tidiest possible start, which is one reason numbers feel like the natural backbone of the game. Beginners can find the complete walkthrough in our UNO rules for beginners.

Frequently Asked Questions (FAQ)

How many number cards are in a standard UNO deck?

There are 76 number cards in a 108-card deck. Each colour has one 0 and two each of the digits 1 through 9, giving 19 numbered cards per colour.

Why is the 0 card so rare?

There is only one 0 in each colour, so just four exist in the whole deck. Every other digit appears eight times, which makes the 0 half as common as any other number.

How many points is a number card worth?

Each number card is worth its face value, from 0 up to 9 points. That is much lower than an action card at 20 points or a Wild card at 50 points.

Can I change the colour using a number card?

Yes. If you play a card that matches the current number but is a different colour, the active colour switches to the colour of the card you played.

Do I still have to say UNO if my last card is a number?

Yes. You must call “UNO” whenever you are down to one card, whatever its type. If you are caught before the next player takes their turn, you draw two cards as a penalty.
