Killer 3D pool pits you against a friend or a computer opponent in four different games of billiards. You don’t need a fancy nickname to knock the balls solid into the pocket, just a keen eye for angles and knowledge of your own strength. Play a game of English 8-Ball, U.S. 9-Ball, U.S. 8-Ball, or Killer pool. In Killer pool, you lose a point every time you miss a shot. The person to run out of points first loses the game.
