Klondike solitaire is the world's favorite single-player card game — and it's free in your browser. Deal out seven columns, build the four foundations from Ace to King, and clear the whole deck one careful move at a time. No downloads, no accounts, no sign-ups: click NEW GAME and the cards are in your hands.
The 52-card deck is dealt into seven tableau columns with only the top card of each facing up; the rest go to the stock. In the tableau, build descending sequences with alternating red and black cards, and move whole face-up runs together. In the foundations, build each suit upward from Ace to King. Click the stock to draw a card one at a time, and click an empty stock to recycle the waste pile back into it. An empty tableau column can only take a King.
Desktop: drag cards between piles, click a card to send it straight to its foundation, click the stock to draw, and use the AUTO button to play out every obvious foundation move for you.
Mobile: touch-drag cards just like a mouse, or simply tap a card to send it to its foundation. Tap the stock to draw and tap an empty stock to recycle.
You win when all 52 cards reach the four foundation piles, each suit built from Ace to King. The game uses standard Klondike scoring: flipping a face-down card earns +5, placing a card on the tableau earns +5, and moving one to a foundation earns +10, while each draw from the stock costs −5. A timer tracks your run, and the final screen shows both your score and completion time.
Klondike earned its fame as the solitaire shipped with Microsoft Windows in 1990, turning an old patience game into a worldwide pastime. This browser version keeps the classic rules — drag and drop, stock cycling, and auto-complete — in a single HTML file with cards that feel like the real thing. It's one of 20 free classic games on ZenClick, perfect for a quiet five-minute break.
