Many Klondike losses come from moving the first card that looks legal without asking whether that move actually helps. The tableau — the seven columns of face-down and face-up cards spread across the middle of the board — is a puzzle, and reading it well is one of the clearest ways to improve. This guide walks through how to scan what's visible, identify what's blocking you, and think two or three moves ahead before you touch anything.
Scanning Visible Cards
When a new game deals, you have 28 cards in the tableau: 21 face-down and 7 face-up. That one face-up card per column is your entire information set at the start. The first thing to do is not move — it's to read.
Start by cataloguing the face-up cards by rank and suit. You're looking for three things immediately: aces and twos (because they go straight to the foundations), kings (because they're the only cards that can fill an empty column), and any card that can be played onto another face-up card right now. A red 6 on a black 7, for instance, is a legal move, but whether it's a good move depends on what's underneath both of those cards.
The columns aren't equal. Column 1 has one face-down card beneath its face-up card; column 7 has six. That asymmetry matters enormously. Uncovering a face-down card in column 7 requires moving a longer sequence and is generally harder to arrange. Columns 1 through 3 are your early-game levers — they flip face-down cards cheaply and give you new information fast.
As you scan, mentally note which suits are represented among the face-up cards. If you can see three hearts already, the fourth heart is probably buried somewhere. If you haven't seen a single spade, there's a good chance several spades are face-down in the deeper columns. This kind of suit accounting becomes more useful as the game progresses and you're trying to figure out why a particular foundation pile isn't moving.
Pay attention to the stock pile too. In Turn 1 you'll see every card in the stock eventually (assuming no reshuffles run out), so the stock is a known quantity you can plan around. In Turn 3 you only see every third card per pass, which changes the calculus significantly — but that's a separate topic covered in the Turn 1 vs Turn 3 comparison.
Identifying Blockers
A blocker is any face-down card sitting beneath a card you need. You can't move the face-down card directly — you have to clear everything above it first. Understanding blockers is the core of Klondike strategy.
The most dangerous blockers are the ones you can't see yet. When you move a face-up card and flip a new card, that new card might be exactly what you needed, or it might be a card that creates a new problem. Before you make a move, ask: what do I want to find under here, and what would be bad to find?
Consider a concrete example. You have a black 9 face-up in column 4, and a red 10 face-up in column 6. Moving the black 9 onto the red 10 is legal. But before you do it, check: is there anything useful sitting on top of the black 9 that would get buried? Is the red 10 in column 6 itself sitting on something you need to uncover? Moving the 9 onto the 10 merges two columns into one sequence, which can be good (you flip a new card in column 4) or bad (you've now locked the 10 in place and can't move it to an empty column to place a king).
Suit blockers are a subtler problem. Suppose you need the 7♥ to continue a foundation run, but it's face-down in column 5 under four cards. You need to clear those four cards. Two of them can move to other columns, but the third requires a specific card from the stock that you haven't seen yet. That dependency chain — stock card → tableau move → tableau move → flip → foundation — is a four-step blocker. Recognizing it early lets you prioritize the stock card when it appears rather than playing it somewhere else.
Empty columns are the most powerful blocker-clearing tool in the game. An empty column can hold any king (and the sequence built on it), which frees up space to maneuver. Getting to an empty column early is often worth sacrificing a short-term gain. If column 1 has only one face-down card and a movable face-up card, clearing it to empty should be near the top of your priority list — even if the move doesn't immediately advance a foundation.
Watch for circular blockers: card A is blocked by card B, which is blocked by card C, which is blocked by card A. These are dead ends. When you spot a circular dependency, the only way out is through the stock pile or an empty column. If neither is available, that game may be unwinnable regardless of how you play it.
Planning a Sequence
Good tableau reading isn't just reactive — it's forward-looking. Before making any move, try to trace the consequence chain two or three steps out.
The mental model is simple: "If I move X, I flip Y. If Y is useful, I can then do Z. If Y is not useful, what's my fallback?" You won't always know what Y is, but you can often narrow the possibilities. If column 3 has a 5 face-up and only one face-down card beneath it, and you know from the visible cards that the 4♠ and 4♣ are both already placed, then flipping that face-down card in column 3 is low-risk — whatever it is, it probably won't make things worse.
Sequence planning also means thinking about foundation timing. It's tempting to send every ace and two to the foundation immediately, but sometimes holding a low card in the tableau is strategically better. A 2♥ sitting on a 3♣ in the tableau is doing work — it's part of a sequence that might uncover something useful. Sending it to the foundation removes it from play and might strand the 3♣ with nothing to go on top of it.
The general rule: send cards to the foundation when doing so opens a move that wouldn't otherwise be available, or when the card has no useful role left in the tableau. Don't send cards to the foundation just because you can.
When you're planning sequences, think in terms of "what does this column need to become useful?" Column 7 with six face-down cards needs a lot of work. But if the face-up card on column 7 is a king, and you have an empty column, you can move that king to the empty column and start building a new sequence there while you work on uncovering column 7 from a different angle. That kind of lateral thinking — using the board's geometry rather than fighting it — is what separates good tableau readers from average ones.

Common Mistakes
The most common mistake is moving the first legal card you see. Legal and good are not the same thing. Always scan the full tableau before committing to a move.
A close second is over-prioritizing the foundations. New players often race to get cards onto the foundation piles, which feels like progress. But a card on the foundation is a card that can no longer help you in the tableau. Aces and twos should go up immediately — they have no tableau value. Threes and fours can usually go up safely. Fives and above should stay in the tableau until you're sure they're not needed for sequencing.
Burning through the stock too fast is another trap. In Turn 1, you get one pass through the stock (or unlimited passes, depending on the ruleset). Either way, each card you play from the stock is a card you've committed. If you play a stock card onto the tableau in a suboptimal position, you might block yourself later. When a stock card appears, ask whether playing it now is better than waiting for a better opportunity.
Finally, don't neglect the face-down cards. Every face-down card is a mystery, and mysteries are risk. The faster you flip face-down cards, the more information you have, and the better your decisions become. Prioritize moves that flip face-down cards over moves that just rearrange face-up sequences.
FAQ
Q: How many moves ahead should I plan in Klondike?
Two to three moves is a practical target for most positions. Beyond three moves, the uncertainty from face-down cards and the stock makes precise planning unreliable. The goal isn't to calculate a perfect line — it's to avoid moves that obviously close off future options. Ask "does this move give me more choices or fewer?" and you'll make better decisions than trying to calculate ten moves out.
Q: Is it ever right to move a king to an empty column even if I don't have a queen to put on it?
Yes, sometimes. If moving the king uncovers a face-down card in a column that's otherwise stuck, the information gain can be worth it. The risk is that you've used your empty column and now have less flexibility. As a rule of thumb: move a king to an empty column if it immediately enables at least one other useful move, or if the column it came from has face-down cards you need to uncover.
Q: What should I do when I'm stuck and can't see any good moves?
First, check whether you've missed any legal moves — scan every column systematically. Second, look at the stock: is there a card there that unlocks something? Third, consider whether any foundation cards could be moved back to the tableau (in rulesets that allow it). If none of those help, the game may be in a dead end. Some Klondike deals are unwinnable regardless of play, so don't assume every stuck position is your fault.
Q: How do I know if a game is unwinnable?
You can't always know for certain without exhaustive analysis. Practical signals include: all empty columns are filled, the stock is exhausted, and no legal moves remain. Circular blockers (A needs B, B needs C, C needs A) are a strong indicator of an unwinnable position. If you've been playing for a while and the foundations haven't moved in many turns, it's worth restarting rather than grinding through a dead game.
Q: Does the order I build tableau sequences matter?
Yes. Building sequences in alternating colors (red-black-red or black-red-black) is required by the rules, but within that constraint, the suit of each card matters for foundation access. If you build a long sequence that buries a card you need for the foundation, you've created a self-imposed blocker. Try to keep foundation-bound cards near the top of their sequences so they can be sent up without dismantling the whole column.
