Klondike is the classic solitaire game, the seven-column original that shipped with every home computer for three decades and that most of the world simply calls "solitaire." This version is free, runs in your browser with nothing to install, and plays exactly the way you remember it: drag cards or tap them, undo as much as you like, and switch between the relaxed Draw 1 mode and the classic Draw 3 challenge at any time.
Your game saves itself automatically, so you can close the tab mid-deal and pick it up later — score, timer and all.
Draw 1 turns a single stock card at a time, so every card is reachable — ideal for learning. Draw 3 turns three at once and only the top one is playable, which makes the stock much harder to use and is the traditional challenge mode.
Klondike only allows a King (or a run headed by a King) to start a new column. If the move is refused, the card you are holding is not a King.
Yes — completely free in your browser, with no download, no account and no sign-up. Hints, undo and both draw modes are all included.
