Regole di Klondike Solitaire

Objective: build four foundation piles, one per suit, from Ace to King.

Setup: 28 cards arranged in 7 columns (1, 2, 3, 4, 5, 6, 7 cards); only the last card of each column is face-up. The remaining 24 cards form the draw deck.

Valid moves: move face-up cards between columns following alternating colour (red-black) descending sequence. Move groups of face-up cards in sequence. Move an Ace to a foundation, then build by suit in ascending order. Flip a card from the deck (1 or 3 at a time depending on variant).

Win condition: when all 52 cards are on the foundations.
