Pyramid Solitaire

You control the game with your mouse, clicking cards to select them. The board is a pyramid of face-up cards, and you work by pairing exposed cards that add up to thirteen. Kings remove themselves alone. The main goal is to clear the entire pyramid, using a stock pile when you run out of moves. The pace is methodical, requiring you to plan a few steps ahead, though luck plays a role in how the stock cycles. It feels like a quiet puzzle, a test of patience and observation more than speed.
