The Ultimate leagues are a system of ranks determined by one of the five medals: Wooden, Stone, Bronze, Silver and Gold. Everyone starts in the Wooden League and is placed in a group of fifty players. Ranks are determined by your rating. Top 10 players get promoted to the next league. A few players who are ranked last are demoted. Once a player reaches gold league which is so far the highest rank received by any player, they keep getting ultimate parts after that depending upon their ranks in further league fights. Even after performing a prestige, your current league position will be maintained. At the end you will see a locked icon that represents something ranked higher than the gold league. Still you cannot get promoted to that. When asked to the Zeptolab team (firstname.lastname@example.org) the support team replied that that part is incomplete and will be available after some updates.
