The 31 card game (also known as Thirty-One, Scat, or Blitz) is a fast-paced traditional game where the objective is simple: collect cards of the same suit that add up to 31 points, or at least outscore your opponents before someone knocks. Played with a standard 52-card deck, it accommodates two to nine players and moves quickly, making it a staple for casual game nights.
To win at 31, you need to master card valuation, track what opponents pick up from the discard pile, and know the exact mathematical moment to knock or hold your hand.
The Basics and Setup
Every round of 31 requires a standard 52-card deck with no jokers. Players each start with a set number of tokens, chips, or lives—typically three.
The dealer distributes three cards face-down to each player one at a time. The remaining deck becomes the central draw pile, and the top card is flipped face-up next to it to start the discard pile.
Card Values and Scoring
Unlike games where runs or sets matter, 31 focuses exclusively on the point total of cards belonging to a single suit. Cross-suit cards do not add to your score; only the highest single-suit total in your hand counts.
- Aces: Worth 11 points (the highest-value card in the deck).
- Face Cards (Kings, Queens, Jacks): Worth 10 points each.
- Number Cards (2 through 10): Worth their face value.
The absolute best hand in the game is an Ace paired with two 10-point cards of the same suit (such as an Ace, King, and 10 of Spades), which totals 31 points. Another common variant rule scores three of a kind (e.g., three 8s) as a flat 30 points, though standard play relies strictly on single-suit totals.
Step-by-Step Gameplay
The player to the dealer's left takes the first turn, and play proceeds clockwise. On your turn, you must perform two actions in order:
- Draw: Take the top card from the face-down draw pile or pick up the top card sitting on the discard pile.
- Discard: Choose one card from your hand and place it face-up on the discard pile. Your hand must always return to exactly three cards.
Knocking and Ending the Round
Instead of drawing and discarding on your turn, you can choose to knock on the table if you believe your hand is strong enough to avoid having the lowest score.
Knocking signals that the round is coming to an end. Once a player knocks, every remaining player gets one final turn to draw and discard in an effort to improve their hand.
Alternatively, if a player draws or holds a hand totaling exactly 31 points, they can reveal it immediately. This instantly ends the round and penalizes all other players, bypassing the need to knock.
The Showdown and Penalties
After the final turn following a knock, all players reveal their hands and calculate their single-suit totals.
- The player with the lowest score loses one token or life.
- If the player who knocked ties for the lowest score with someone else, the knocker is safe, and the other player loses the life (since they had an extra turn to improve).
- If two players who did not knock tie for the lowest score, both lose a life.
- If someone reveals a natural 31, every other player immediately loses a life.
When a player loses all three lives, they enter a final status often called "on the county". One more lost life eliminates them entirely. The last player remaining with active lives wins the game.
Tactical Strategies to Win
Winning at 31 requires balancing aggression with careful observation of the discard pile.
- Commit to one suit immediately: Trying to juggle two different suits across three cards severely limits your scoring potential. Pick your highest-value card on the deal and discard cards from other suits right away.
- Track the discard pile: Pay close attention to what opponents pick up. If someone draws a 9 of Hearts from the discard pile, stop feeding hearts into that pile, and look out if they start dropping spades.
- Know when to knock early: In a large group, someone else is likely building a strong hand. If you hold a middling score like 25 or 26 early in the round, knocking can catch opponents before they assemble higher totals.
- Value Aces and 10s: Holding an Ace gives you immense flexibility because it pairs with any high face card to push toward 31.

Frequently Asked Questions
What happens if the draw pile runs out before anyone knocks?
If the stock pile is completely exhausted and no one has knocked, the discard pile is flipped over to create a new draw pile (leaving the top card in place), and play continues.
Can you win with a hand that isn't 31?
Yes. The goal of most rounds is simply to avoid having the lowest score at the table. You can win a round with 22 points as long as another player holds 19.
How many people can play 31 effectively?
While two to nine players can technically play, the game flows best with three to six players. Too few players makes the discard pile predictable, while too many drains the deck too quickly.
What is the penalty if two players tie for the lowest score?
If two players who did not knock share the lowest score, both lose a life. If a non-knocker ties with the person who knocked, only the non-knocker loses the life.
