Black Hole Solitaire

Start the game by positioning the black hole card at the center of the board. Surround the black hole with an arrangement of face-up cards. Move cards to the black hole by selecting a card that is one rank above or one rank below than the current top card of the black hole. Proceed this sequence until all cards are moved to the black hole or no more moves are possible. Use the undo button to take back your last move if needed. Complete the game by clearing all cards to the black hole. Test yourself by striving to complete the game in as few moves as possible.
