Klondike is the classic solitaire card game. Build four foundation piles from Ace to King by suit. On the tableau, stack cards in descending order alternating red and black. Only a King fills an empty column. Click the stock to draw cards — Turn 1 draws one card, Turn 3 draws three.
Drag cards, or tap a card then tap where it should go. Double-click a card to send it to the foundation. Use Undo to take back moves and Hint when you're stuck.
Waste to tableau +5, card to foundation +10, flipping a tableau card +5, foundation back to tableau −15, recycling the waste pile −50. Turn 1 is relaxed; Turn 3 is the classic challenge.
