Black Hole Solitaire

Begin the game by placing the black hole card at the center of the board. Circle the black hole with an arrangement of face-up cards. Transfer cards to the black hole by choosing 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 transferred to the black hole or no more moves are possible. Employ the undo button to reverse your last move if needed. Complete the game by transferring all cards to the black hole. Try yourself by striving to complete the game in as few moves as possible.
