The point system was replaced , and instead of scoring for each ball (one point per ball), a unit is taken of the total number of balls each player has left. Each player has 7 balls left to score in the beginning of the game. If a player places one of his balls (solid or stripped) in , he would have 6 left to score with, before being able to score with the black ball. 

It was implemented so that, if a player would score with the back ball and still had colored balls to score with, the black ball would re-spawn in its original position. If a player would score with an opponent's ball, the opponent would have one less ball left to score with, this way, there is no motivation to score with the opponent's balls.
