Black Hole Solitaire

Launch the game by positioning the black hole card at the center of the board. Circle the black hole with a layout of face-up cards. Move cards to the black hole by clicking on a card that is the next in sequence 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. Employ the undo button to correct your last move if needed. Win the game by transferring all cards to the black hole. Challenge yourself by attempting to complete the game in as few moves as possible.
