Klondike Solitaire

Draw one card at a time. Build tableau stacks down in alternating red and black. Only Kings enter empty columns. Build each foundation from Ace to King in its own suit. Tap a card, then its destination, or drag a stack. Double-click a top card to make a legal foundation move. Undo reverses the last move; Hint highlights one option. Win by moving all 52 cards to foundations.

Scoring: +5 for each newly exposed hidden card; +10 for each card first moved to a foundation; +500 for completing the deck. No points for cycling the stock or repeated foundation moves. Undo restores the previous score.
