How to Play Klondike Solitaire
Klondike starts with seven tableau columns. The first column has one card, the second has two, and the seventh has seven. Only the top card of each column is face up at the start. Use the stock to draw a new card into the drawn-card pile, then move that card or any face-up tableau sequence when it fits the rules.
Klondike Rules
Build tableau piles in descending rank with alternating colors: a black 7 can go on a red 8, a red queen can go on a black king, and so on. You may move one face-up card or a valid face-up sequence. Empty tableau columns accept only kings or a sequence that starts with a king. Foundations start with aces and build upward by suit until each suit reaches king.
Controls
Click a face-up card and then click a valid tableau pile or foundation. You can also drag cards on desktop-style pointers or use a quick second click for an automatic legal move.
Goal
Move all 52 cards to the four foundations. Completed rounds can be saved locally with time and move count.
Klondike Tips
A good Klondike round is usually about opening hidden cards before making tidy-looking moves.
Open face-down cards first
When two moves look similar, prefer the one that reveals a face-down tableau card. More visible cards give you more legal moves later.
Use empty columns for kings
Do not clear a tableau column unless you have a king, or a king-led sequence, ready to place there. Empty columns are powerful but easy to waste.
Move to foundations carefully
Aces and twos are usually safe to move up. Higher cards can sometimes block tableau moves, so leave them in play when they still help build alternating-color sequences.
