There are 4 divisions (more players join, the number of divisions increase) and 15 leagues. There is only 1 league in the first division and the number of leagues for the next division is multiplied by 2. The hierarchy is as structured below.
At the end of the season, the top 2 clubs in each league are promoted up into a league in the next higher division and the bottom 4 clubs in each league are relegated into a league in the next lower division.
League matches are played every day, which means a single league season lasts for 20 days. User earns X amount of coins for winning a league match, Y amounts of coins for a draw and no coins for losing.
Each division has a prize pool which is equally divided among the leagues in the Division. League winners and runner-ups share the prize pool.
