An abstract game of losing meteors, the aptly if generically named game of Black Hole revolves around setting your asteroids on paths that will have them ricochet off other asteroids, straight into the pocket in the center. Every turn you get to move one of your pieces in a straight line orthagonically - like a giant space rook. If they strike another of your pieces, that piece gets hurled to either side in a straight line. Pieces that cross the black hole in the center get removed from play - first to remove four pieces in this way wins the game.
