About Thirty-One (Scat)
What Is Thirty-One (Scat)?
Thirty-One, often called Scat or Blitz in North America, asks you to make the best three-card hand in a single suit. A king, queen, and ace of hearts total 31; three strong cards in different suits may score far less. This browser version lets you draw from a hidden stock or a visible discard against one CPU. Every turn has a small question: improve your suit, keep your present score, or knock and compare hands. Start with three cards and decide what belongs together.
How to Play Thirty-One (Scat)
- You and the CPU receive three cards each from a shuffled 52-card deck. One card starts the face-up discard pile; the rest form the stock. Inspect your three cards, then choose a stock card or take the top visible discard.
- After drawing, click one of your four cards to discard it. You may discard the card you just picked up. The CPU takes its own turn and discards afterward. You can see your current score above your hand, but the CPU's cards remain hidden.
- If you want to stop drawing, click Knock at the start of your turn. Aces score 11, picture cards 10, and number cards their printed value. Add only cards of the same suit, then use the largest of your four possible suit totals.
- This browser duel compares the two hands on a knock, or as soon as a hand reaches 31. It also uses the common optional three-of-a-kind value of 30.5. Full Scat usually gives each opponent one final turn after a knock, and often tracks lost lives over several rounds; this page is a single-hand practice.
Basic Rules
- Exactly three cards remain in each hand after every discard. A hand with ace of spades, king of spades, and seven of hearts scores 21, not 28; only spades count toward its best suit total.
- Three of a kind counts as 30.5 under this page's chosen variation. Three tens of the same suit cannot exist in one standard deck, but a ten, jack, and queen of the same suit make 30. A same-suit ace with two ten-point cards makes 31.
- Take only the top card of the stock or discard. The face-up discard tells you exactly what you can gain; the hidden stock might provide a better suit card or a useless rank. This is Scat/Blitz, not German Skat or the unrelated Greek banking game called 31.
Strategy Tips for Beginners
- Score by suit before judging individual ranks. Two hearts worth 19 can be a better foundation than an isolated ace worth 11.
- Prefer a face-up card that completes 31. There is no reason to gamble on a hidden stock card when the visible discard guarantees an immediate finish.
- Keep an eye on the opponent's discards. Repeated hearts in the discard suggest the CPU is probably building a different suit, although you cannot see its hand.
- When your hand contains three different suits, seek a second card in your strongest suit. One matching picture card can add ten points at once.
- Knock when your hand is strong enough to beat a plausible opponent, not merely when you are bored of drawing. The CPU's hidden cards make this an informed risk rather than a certainty.
Real Examples of Gameplay
Choosing a suit
You hold ace of clubs, nine of clubs, and king of diamonds. Your best suit total is 20 clubs. The king counts 10 only if diamonds become your best suit. A club picture card would make 30.
Taking the discard
You hold ace and queen of spades plus a five of hearts. The discard shows the spade king. Take it and discard the heart five. Your spades now total 31.
A matching trio
Your hand holds three nines. The browser scores it as 30.5 under the selected variant. It beats a 30-point suited hand but loses to a 31.
Variations of Thirty-One (Scat)
- Schwimmen: The related German 31 swaps cards with a three-card face-up pool rather than drawing and discarding.
- Three of a kind: Some Scat tables score three matching ranks as 30, others as 30.5. This page uses 30.5.
- Gin Rummy: Try Gin Rummy for another draw-and-discard game with a different meld objective.
Why People Love Thirty-One (Scat)
- A three-card hand makes the arithmetic quick. You can read the visible discard and immediately see whether it improves your best suit. Deciding when to stop remains hard because the CPU's three cards are hidden.
- The two draw sources give each turn a clear contrast: a known card that may reveal your plan, or an unknown card that preserves flexibility. A short deal offers several meaningful choices without a long score sheet.
