Black Hole Solitaire

How to Play

Start the game by placing the black hole card at the center of the layout. Circle the black hole with an arrangement of face-up cards. Move cards to the black hole by clicking on a card that is one value higher or one value lower than the current top card of the black hole. Proceed this sequence until all cards are cleared to the black hole or no more moves are possible. Use the undo button to reverse your last move if needed. Complete the game by transferring all cards to the black hole. Try yourself by attempting to complete the game in as few moves as possible.
