Black Hole Solitaire
All 52 cards are dealt into 17 piles of three. The Ace of Spades starts the Black Hole. Play any pile’s top card onto the Black Hole if it is one rank above or below the current top — suit does not matter, and the rank wraps (Ace and King are adjacent). Send every last card into the Black Hole to win.
Click any top card to play it on the Black Hole.
