With the recent update, Clan Games is added. Basically, in this event, you do tasks and get points for every successful completion of each task, with points maxed at 500.
In a clan, members can check the leaderboards to see who has the most points collected in their clan. However, with a max of 500, and multiple people with 500 points, it's hard to see how you actually get first. It is not time-related (i.e first to 500 is automatic first place) as a new number one appeared in my clan.
So how do you actually end up in first place in your clan for Clan Games assuming there are multiple people that have reached the point cap of 500 (i.e if players A, B, C, and D have met the cap, who ends up in first)?
