Black Hole is a solitaire card game that is akin to Golf and Tri Peaks. The objective of this game is to compress the entire deck into one foundation.
The cards are dealt to the tableau in piles of three. The leftover card, dealt first or last, is placed as a single foundation called the Black Hole.
Only the top cards of each pile in the tableau are available for play and in order for a card to be placed in the Black Hole, it must be a rank higher or lower than the top card on the Black Hole. This is the only allowable move in the entire game.
The game ends if there are no more top cards that can be moved to the Black Hole. The game is won if all of the cards end up in the Black Hole.
