Klondike — the version of solitaire that ships with almost every desktop operating system — is winnable far more often than most players think. A player who tidies the tableau constantly wins maybe one game in eight; a player who follows the ordering rules in this guide wins closer to one in three. The difference is not patience but priority. Here is what to actually do.
The Board and the Goal
Klondike lays out seven columns. The first column has one card, the second has two, and so on to seven; the last card in each column is face up and the rest are face down. A stock (remaining face-down cards) and a waste pile sit on the left, and four empty foundation slots sit at the top right.
Your goal is to build all four foundations from Ace to King by suit. Two movement rules apply:
- In the tableau, cards stack in descending order with alternating colours — a red 7 can sit on a black 8, and you can move a whole descending sequence together.
- On the foundations, cards must go in ascending order of the same suit, starting with the Aces.
An empty column accepts any card or sequence, and building onto an empty column is one of the most powerful moves available because it exposes the facedown cards beneath.
Rule One: Dig the Stock Before You Tidy the Tableau
Every face-down card in the tableau is a locked resource, but so is the stock. Players who spend their first minutes rearranging visible cards often waste moves on cosmetic ordering while the real bottleneck — unrevealed cards — stays untouched.
Until a fair amount of the stock has been cycled, your default action is: if a move reveals a face-down card, or advances a card to a foundation, do it; otherwise draw from the stock. Tidying sequences that reveal nothing is the most common rookie mistake.
Rule Two: Foundations Are Not Always the Answer
The obvious goal is to push cards to the foundations, and that is usually right. But there is an important exception: an Ace or a low card in a foundation can be better left in the tableau if it is the only thing holding a long sequence together.
More generally, remember that foundation cards are permanently out of play. If a 3 is doing useful work as the bottom of a column — for instance, allowing you to move a sequence onto a 4 — sending it to the foundation removes an option you may need later. The heuristic is: advance to the foundation unless doing so breaks a sequence you cannot rebuild.
Rule Three: Empty Columns Are the Most Valuable Squares on the Board
An empty column can hold any card, which makes it the tool that unlocks buried cards. Two rules follow:
- Do not fill an empty column with a King unless it reveals a facedown card or frees another column entirely. The King is the least useful card to park, because a King on an empty column is exactly as stuck as it sounds — nothing can be built on it.
- Do not empty a column you cannot immediately repurpose. Vacating a column looks tidy, but if you cannot move the remaining sequence anywhere useful, you have spent moves for nothing.
Rule Four: Move Sequences That Reveal Cards
When you have a choice between two legal moves, prefer the one that exposes a face-down card. That single rule improves win rate more than any advanced tactic, because face-down cards are the only source of new information in the game. Every reveal changes what is possible; every non-revealing move changes almost nothing.
Rule Five: Build Red-Black Alternating in Both Useful Directions
Colours must alternate in the tableau, so a card has at most two legal parents. When a card could go to either of two places, prefer the parent that keeps the longest sequence intact and, again, that reveals something.
A subtle point: it is often better to keep a long run of a single colour out of the way on a column you are not planning to dig, so your working columns stay flexible. Experienced players effectively "park" awkward cards in the least useful column.
How to Handle a Blocked Game
- Cycle the stock fully before giving up. In draw-three variants, cards you need may only become playable on the third pass.
- Re-scan the whole tableau after each foundation move. A new foundation card frequently unlocks a card you previously could not place.
- Count remaining facedown cards. If twenty are still hidden and you have no reveals available, the game is likely lost and it is faster to deal a new one.
- Check the colour pattern. A tableau where two red 6s both sit under black 7s with no 5s available is structurally stuck — recognise it early.
Frequently Asked Questions
Is Klondike solitaire winnable every time?
No. With draw-one deals, roughly 80% of games are technically winnable with perfect play, and with draw-three deals that figure is lower. Nobody wins every deal — the aim is to win the deals that are winnable.
What is the single most important habit?
Always prefer a move that reveals a facedown card. It sounds small and it is the largest single lever you have.
Should I always move Aces up immediately?
Almost always, yes — with the exception of a 2 or 3 doing structural work at the base of a long column. Aces almost never hurt to promote.
Draw one or draw three?
Draw one is significantly easier and better for learning; draw three is a harder challenge once the basic ordering rules feel natural.
Play With One Rule at a Time
For your next five games, use only the first rule: never make a tidy-up move when a reveal or a foundation move is available. You can play Klondike solitaire free online here, read more about how these games are built in our browser game genres guide, or browse the puzzle games category.
