Black Hole Solitaire

How to Play

Begin the game by placing the black hole card at the center of the playing area. Circle the black hole with a layout of face-up cards. Shift cards to the black hole by selecting a card that is the next in sequence or one value lower than the current top card of the black hole. Proceed this sequence until all cards are transferred to the black hole or no more moves are possible. Use the undo button to reverse your last move if needed. Succeed the game by removing all cards to the black hole. Challenge yourself by attempting to complete the game in as few moves as possible.
