Black Hole Solitaire

How to Play

Start the game by setting the black hole card at the center of the playing area. Surround the black hole with an arrangement of face-up cards. Transfer cards to the black hole by selecting a card that is one value higher or one value lower than the current top card of the black hole. Keep going this sequence until all cards are moved to the black hole or no more moves are possible. Use the undo button to reverse your last move if needed. Win the game by clearing all cards to the black hole. Challenge yourself by striving to complete the game in as few moves as possible.
