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.

Begin the game by positioning the black hole card at the center of the playing area. Surround the black hole with a pyramid of face-up cards. Move cards to the black hole by choosing a card that is one rank above or one rank below than the current top card of the black hole. Keep going this sequence until all cards are moved to the black hole or no more moves are possible. Utilize the undo button to reverse your last move if needed. Complete the game by removing all cards to the black hole. Test yourself by striving to complete the game in as few moves as possible.
