How to win at solitaire (more often)

Klondike solitaire has a reputation as a luck game, and the reputation is wrong. Solver studies put the share of winnable draw-1 deals at roughly 80% (draw-3 nearer 60%), while typical human win rates sit far below that — which means the gap between your rate and the ceiling is strategy, not shuffle. This guide covers the decision rules that close the gap, all practisable in the solitaire here, which counts your wins on-device and has an unlimited, judgement-free undo.

Most deals are winnable — you lose them

The core insight is informational: you start seeing 28 tableau cards' worth of positions but only 7 faces. Losses mostly trace to moves that felt productive but revealed nothing — shuffling visible cards between columns while 21 cards stay face-down. Reframe the game: your true objective in the early and middle game is not "move cards up", it is turn face-down cards face-up. Information is the scarce resource; foundations bank themselves once the information exists. Every guideline below is this principle in a different costume.

The priority order for every move

When several moves are legal, take the first available from this list:

1. A move that flips a face-down card. Almost always right, and between two options, unbury the taller face-down pile — those cards are the hardest to reach later.
2. Aces and twos to the foundations. These are safe on sight; nothing in the tableau ever needs them. (Threes and up: see below.)
3. A move that opens a useful build. Prefer builds that will accept a card currently trapping a face-down pile.
4. A stock draw. Not a wasted turn — but the reflex to rearrange visible cards first, drawing only when stuck, is what separates deliberate play from card-shuffling.

And one standing veto: never make a move that achieves nothing but motion. Moving a 7 between two black 8s changes the position not at all and, in draw-3, can cost you the stock cycle.

Empty columns and the king rule

Only kings may occupy an empty column, which makes empty columns precious and easy to waste. The rule: do not empty a column unless a king is ready to take it — visible and reachable, with a queen in prospect. An empty column with no king available is a dead space that shrinks your options; a column emptied for a king is a new lane for the whole game. Choose your king like an investment: prefer the colour whose queen and jack you can see, and remember that a king planted with nothing to build beneath it can permanently wall off the column. Sequencing decisions like these — sacrificing immediate motion for structure — is the same instinct that 2048 strategy that actually reaches 2048 and Tic-tac-toe: the never-lose strategy train in their own games.

When NOT to play to the foundations

The counterintuitive rule that most improves intermediate play: cards on the foundations are out of the game, and the tableau still needs low cards to build on. Send a red 4 up too eagerly and the black 3 you draw later has nowhere to live — possibly locking the game. The working heuristic: aces and twos always; from threes upward, promote a card only when both cards of opposite colour and one rank lower are already up or provably not needed. A steady, slightly reluctant foundation is the mark of a player thinking ahead; a sprinting one usually belongs to someone about to lose with 40 cards up. The undo button, used honestly, is a training tool here — rewind and ask what the eager promotion cost you.

Draw-3: playing the stock cycle

Draw-3 shows you every third stock card, which sounds like pure punishment but is actually a puzzle layer: the stock's order is fixed, so using a card changes which cards surface next cycle. Skilled draw-3 play sometimes deliberately declines a playable waste card to shift the alignment — an offset trick worth experimenting with via undo. General draw-3 adjustments: value tableau flexibility even more, plan around the waste cards you have seen, and accept that some deals are genuinely dead — knowing when to redeal is itself strategy. Whether your temperament prefers the friendlier draw-1 or the fuller puzzle of draw-3, both modes are here; Yacht and sudoku are the neighbouring solo-thinking games, and How random is a random number generator? explains what a fair shuffle even means.
