 Winning a Super Nine tournament was worth roughly half the points (370) of winning a Grand Slam tournament (750), while International Series Gold tournament was worth as much as 360 points depending on the total prize money.The format continued until 2000 at which time the Super Nine were renamed the Masters Series (the winner being awarded 500 points), occupying the rank below the Grand Slams (1000 points for the winner), and the International Series Gold were renamed to simply the Championship Series (worth 250 to 300 points for the winner).In 2000, the Grand Slam tournaments and the Masters Series tournaments became mandatory professional events if a player's ranking qualifies them for the tournament.
