Black Hole Solitaire

Launch the game by positioning the black hole card at the center of the playing area. Circle the black hole with a pyramid of face-up cards. Shift cards to the black hole by selecting a card that is one value higher or one rank below than the current top card of the black hole. Continue this sequence until all cards are cleared 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. Challenge yourself by aiming to complete the game in as few moves as possible.
