18 top world women players were to be selected to compete in these tournaments. Each player agrees and will contract to participate in exactly four of these tournaments. Players must rank their preference of tournaments once the final list of host cities is announced and the dates are allocated to each host city. Each tournament is a 12-player, single
round-robin tournament. In each round, players scored 1 point for a win, ½ point for a
draw and 0 for a loss. Grand prix points were then allocated according to each player's standing in the tournament:
160 grand prix points for first place, 130 for second place, 110 for third place, and then 90 down to 10 points by steps of 10. In case of a tie in points the tied players share grand pix points evenly. Players only counted their best three tournament results. The player with the most grand prix points is the winner. ==Players and qualification==
