What Is the Card Game 31?
31 (also known as Scat, Blitz, or Knock) is a classic draw-and-discard card game played with a standard 52-card deck. The goal is simple: build a hand in a single suit that totals as close to 31 points as possible — or at least beats your opponents. It's fast, social, and easy to learn, making it a staple at casual game nights and some casino-style settings.
Basic Rules of 31
Each player is dealt 3 cards face-down. The remaining cards form a draw pile, and one card is flipped to start the discard pile. On your turn, you can:
- Draw from the top of the draw pile or the discard pile
- Discard one card face-up onto the discard pile
- Knock to end the round (instead of drawing), signaling you're confident in your hand
The round ends immediately if a player achieves exactly 31, or after all players have had one more turn once someone knocks.
Card Values in 31
| Card | Point Value |
|---|---|
| Ace | 11 points |
| King, Queen, Jack | 10 points each |
| 2 through 10 | Face value |
Crucially, only cards of the same suit are added together. If you hold a 10 of Hearts, 9 of Hearts, and King of Spades, your hand value is 19 (the two Hearts only). Mixed suits do not combine.
How to Win (and Lose)
After the round ends, players reveal their hands. The player with the lowest hand value loses a life (most versions give each player 3 lives, represented by coins or chips). Special rules:
- If you knock and have the lowest hand, you lose two lives instead of one.
- If a player hits exactly 31, everyone else loses a life immediately.
- Three-of-a-kind (any three cards of the same rank) typically counts as 30.5 points — a very strong hand, but not unbeatable.
Winning Strategies for 31
1. Focus on One Suit Early
Don't try to collect high cards across multiple suits. Commit to building in the suit where you already have the highest combined value. Splitting your focus is the most common beginner mistake.
2. Watch the Discard Pile
The discard pile gives you information about what your opponents are collecting. If high Hearts keep getting discarded, your opponents aren't building Hearts — which could mean the draw pile is rich with them.
3. Know When to Knock
Knocking is a calculated risk. A hand of 24–26 in a single suit is generally a reasonable knock, especially in later rounds. Knock too early and a better hand beats you; wait too long and someone hits 31.
4. The Art of the Block
If you notice an opponent consistently picking up from the discard pile, start discarding cards that don't help them — even if those cards are moderately useful to you.
Common Variations
- Casino 31: Players compete against the dealer rather than each other, with structured betting rounds.
- Speed 31: No knocking — the round ends the moment any player reaches 31.
- Four-card 31: Played with 4 cards per hand, significantly changing scoring strategy.
Final Thoughts
31 is one of those rare card games that's genuinely easy to pick up but rewards patience and observation. Whether you're playing for fun or in a structured setting, understanding hand values and reading the table will set you apart from players who are simply chasing high numbers without a plan.
