Free online Klondike Solitaire — no download, no sign-up.
Tap a card to select it, then tap where it should go. Double-tap to send a card to the foundations. 0/52 home.
This is Klondike — the Solitaire everyone means when they say 'Solitaire', the one that shipped with Windows and quietly became one of the most-played games in history. Your goal is to build all four suits up from Ace to King on the foundations, working through a shuffled deck by stacking cards in descending order and alternating colours down the seven tableau columns. It runs entirely in your browser with no download, no account and no ads interrupting a game.
Play your way: choose Draw 1 for a relaxed, almost always winnable game, or Draw 3 for the tougher classic challenge. Tap a card and tap where it goes, double-tap to send a card home to the foundations, undo a misstep, and hit Auto-finish once the outcome is decided. A timer and move counter track each game so you can chase a personal best.
