Black Hole Solitaire

Launch the game by positioning the black hole card at the center of the board. Circle the black hole with an arrangement of face-up cards.

Proceed this sequence until all cards are moved to the black hole or no more moves are possible. Use the undo button to correct your last move if needed. Succeed the game by transferring all cards to the black hole. Test yourself by aiming to complete the game in as few moves as possible.
