Black Hole Solitaire

Black Hole is an addictive solitaire card game with similar rules as Tri Peaks or golf solitaire. Your goal is to move all cards to the black hole by either counting up or counting down in value.

Launch the game by positioning the black hole card at the center of the playing area. Surround the black hole with an arrangement of face-up cards. Shift cards to the black hole by choosing a card that is one rank above or one value lower than the current top card of the black hole. Keep going this sequence until all cards are cleared to the black hole or no more moves are possible. Employ the undo button to take back your last move if needed. Succeed the game by removing all cards to the black hole. Challenge yourself by aiming to complete the game in as few moves as possible.
