When you play games, you win or lose trophies depending on the result. To move up in the league, you need to win more trophies. Each table has a limit for the maximum amount of trophies that can be won playing that table. You will still be able to play on this table, but you will not earn any additional trophies. At the end of every season, your trophy count is reset when the league ends.
