Six common Klondike Solitaire mistakes (and how to fix each one)
Most Klondike Solitaire games are lost in the first ten moves, not the last ten. The cards you cannot reach in turn 50 were buried by a decision you made in turn 5. This article walks through the six mistakes that cost the most games and the simple habits that prevent them.
These habits roughly double the win rate of a casual player. They are not advanced — there is no card counting, no probability calculation, no memorisation. They are the difference between playing and just clicking.
1. Sending an ace to the foundation too early
The moment you see an ace, the instinct is to send it to the foundation. Sometimes this is right. Often it is wrong.
An ace in the foundation cannot be moved back to the tableau. But aces are useful on the tableau too — a black ace under a red two on a column lets the column keep growing. If you send the ace away the moment you see it, you might find later that you need it as a foundation for the two that arrives next turn, or as a column anchor for the rest of the game.
The fix: do not send an ace to the foundation until you have a use for the two of the same suit, or until the column the ace came from is empty and you cannot do anything useful with it on the board.
A more concrete rule: if sending the ace blocks a face-down card from flipping, wait.
2. Flipping the stock before scanning the board
The stock pile is appealing because it is full of new cards. Every click on the stock reveals something. Most players click it the moment they cannot make a move that immediately turns over a face-down card.
But the board is rarely that simple. There are usually two or three quiet moves available — moving a card between columns that does not flip anything new, but unlocks the next move. If you flip the stock before you scan, you skip these moves. Each skipped move is a card you cannot use later.
The fix: before each click on the stock, take five seconds to look across the entire tableau. Can you move a black six onto a red seven? Can you move a card from the waste onto a tableau column? Can you swap two cards to free a buried card later? If yes, do those first. Only when the visible board is fully optimised should you flip the stock.
3. Burying a card you will need
Klondike has one direction: cards on the tableau go down by rank, alternating in colour. This means every time you put a card on the tableau, you are committing to needing the next-lower-rank opposite-colour card eventually.
A common mistake: moving a red queen onto a black king when you do not yet have the black queen-jack-ten chain set up. The red queen now sits on the king with nothing under it. To use it later, you have to find the black jack first. If the black jack is still face-down somewhere, you have just made your own life harder.
The fix: before moving a high card onto an empty space or a tableau king, ask: “Do I have the chain to keep using this column?” If you do not, the card is better off staying where it is.
4. Emptying a column without a king ready
Empty tableau columns are the most powerful resource in Klondike — only kings can fill them, and kings can move around freely once a column is empty.
But an empty column with no king to fill it is dead weight for ten turns. You cannot put a queen there, you cannot put a jack there, you cannot put anything but a king. If your only available kings are deep in face-down cards, you have created a hole in your board that lasts until you dig out one of those kings.
The fix: before clearing a column, count your reachable kings. A king on the waste, or face-up on top of a column, counts. A king buried under three face-down cards does not count. If you have at least one reachable king, clear the column. If you do not, wait.
5. Treating face-down cards as “later” problems
Every face-down card on the tableau is a question. It might be the card you need next turn, or it might be the card that blocks you for the rest of the game. You cannot tell until you flip it.
A common pattern: players make moves that look productive — sending cards to the foundation, building up nice colour-alternating chains on the tableau — without flipping any face-down cards. The board looks tidier. But after ten such moves, the same face-down cards are still sitting there, and now the resources on top of them are also locked away.
The fix: prioritise moves that flip face-down cards above all other moves except clear blockers (like a same-suit ace blocking a 2 you need). On any given turn, your first question should be “what move would flip a face-down card?” Only when the answer is “nothing right now” should you make a different move.
6. Forgetting to look at the waste pile
The waste pile feels like spent resources — cards you have already considered. But the top card of the waste is always playable. It can move to a tableau column, or to a foundation, just like any face-up card.
In Draw-1 (which is what Big Card Solitaire plays), every card in the deck rotates through the waste at least once. The top of the waste is the next playable card from the stock. If you ignore it, you are ignoring potentially one-third of your usable cards at any moment.
The fix: every time you scan the board (see mistake #2), include the waste pile. The top card of the waste is just as available as any tableau top card. If it can move productively, move it.
Putting it together
These six fixes — wait on aces, scan before flipping, build before burying, count kings before clearing, prioritise face-down flips, watch the waste — turn most losing games into competitive ones. They will not win every deal — Klondike has a meaningful luck element and roughly 10 percent of deals are unwinnable from the start — but they push the player into the range of winning about half their games instead of one in five.
If you want to practise them, play a few deals now. The hint button shows the best move on the current board if you get stuck; use it sparingly and try to notice why the suggestion is good.
