Trust fans to ask about the rules of a fictional game, rather than plot holes in the Harry Potter series, the first book of which was published two decades ago.
In the ensuing years since the Golden Snitch (a small flying ball in the game of Quidditch) was first introduced, Rowling has apparently been repeatedly asked why she wrote in her novel that the person to catch it won their team 150 points.
These folks claim the disparity between Quaffle goals (10 points each) and catching the Golden Snitch (150 points, and ending the game) means the player known as the 'Seeker', who catches the Golden Snitch, will always wins the game for their team.
Basic arithmetic will tell you that you only need to be at least 16 Quaffle goals ahead to win, without your Seeker catching the Golden Snitch - though admittedly why would a Seeker who was over 16 goals behind try to catch the Golden Snitch?
True fans would point out that in book four, Harry Potter and the Goblet of Fire, such a game does end with the losing side's Seeker catching the Golden Snitch.
During the Quidditch World Cup final, Bulgaria loses to Ireland, because Bulgarian Seeker Viktor Krum catches the Snitch when his team were over 160 points behind.
The final score was 170-160 to Ireland.
OK. We admit it. This was all an excuse for some quality Krum time.
Other fans, responding to Rowling, posed their own pressing concerns about the Harry Potter series:
Where does Hagrid go to the toilet?
@jk_rowling Who cares about snitches when hagrid doesn't have a bathrm? Does he have to go poo in the forbidden forest???
