There are 4 to 5 tournaments in the Grand Prix series each year, and a player can play in any number of them.

A player’s total score will be the sum of their 3 best scores. Players who play in fewer than three tournaments will still have the sum of their scores counted towards the consideration of the prizes, so for example, a player who scores  4+4=8 will still finish ahead of a player that scores 2 in 3 tournaments, for a total score of 2+2+2=6. For players who change age groups, their score will be computed separately for each age group, and then the highest of the 2 will be their total score.
