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 placing the black hole card at the center of the board. Circle the black hole with an arrangement of face-up cards. Transfer cards to the black hole by choosing a card that is one value higher or one value lower than the current top card of the black hole. Keep going this sequence until all cards are transferred to the black hole or no more moves are possible. Use the undo button to take back your last move if needed. Complete the game by removing all cards to the black hole. Challenge yourself by aiming to complete the game in as few moves as possible.
