Points for the weekly ranking are calculated from Monday to the end of Sunday of a given week.
Tournament points (see here) and points for catching the Fish of the Day (see here) are taken into account.

Players can earn a maximum of 500 points per day, giving a maximum of 3,500 points per week - 3 x 125 for tournaments and an additional 125 points for the Fish of the Day.
Players can get ex aequo places.
At the end of the week, the top 10 players from every ranking are awarded. In addition to Cups as rewards, there are ground baits, strength bonuses, experience bonuses and banknotes.
Players can check the results from the last weekly ranking in the "Last Ranking" tab.
