Personally, I believe the problem of this mini game is the fact that when there are so many players (+6, I would say), the pixies usually likes to go to up, which makes them unreachable. Probably if they place a barrier on top in a way that the pixies are always reachable, it would make the game faster, without waiting until the timer runs out.
Plus, I think there are worse round, like hide the coin, (which luckily or unluckly in my 15 games of party games didn't got that minigame), and tag, which looks like that bug happens less, but that still happen, sadly. And that can change everything.
