All players joining the BPL during a season will start in the Bronze League.

Players in the Bronze, Silver, Gold and Platinum Leagues are divided into groups of 25 people.

Thus, early in the week, or when you start a season, you are placed in a group. This group will remain the same until the end of the week.
From there, each week: 
  • The "Top 20%" (the first 5) will be promoted into higher league the week after. 
  • The "Flop 20%" (the last 5) will be relegated to the lower league (except of course for the Bronze League, since there is no league below it). 
  • Players ranging between those two groups will remain in the same league.
The Diamond League is a unique group: that is to say that all players in Diamond League are competing against each other. Only the top ranked players in this league will be promoted by the end of the week! Attention, the "Flop 20%" (20% of the players who won the least points during this period) will be relegated.
The Elite League is a unique and very special group, since it is reserved for the top 100 of the game. To get to Elite League, one would obviously need to climb the steps one by one before the end of the season. The competition in this group is even more fierce since half of the group ("Flop 50%") will be relegated to the Diamond league at the end of the week.
