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 layout. Circle the black hole with a pyramid 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 cleared to the black hole or no more moves are possible. Use the undo button to reverse your last move if needed. Win the game by removing all cards to the black hole. Challenge yourself by attempting to complete the game in as few moves as possible.
