Leagues are the Matchmaking tier you are placed in. During battles, you play against players close to or at your league. The leagues are as follows: Recruit, Private, Bronze, Silver, Gold, Diamond, Expert, Master and Champion, the highest league.
Every time you move up a league, you gain gold, which encourages some to win, instead of tanking. There is also the Legend League, which is the top 50 players. These players tend to have trophy counts above 5500, which is a player's challenge to match. To move up a league, players have to win battles. The more damage they deal, the more trophies they get. Losing battles makes players lose trophies.
Upon launch of the Leagues you could still make points even if your team lose - if your damage was on top-3 upon your team. This leads to common situation where players were ditching teamplay and beacon capturing, and just hunt for most damage.
There is an exclusion to the rule, however - lowest league player (Private and Recruit) can receive minimum of zero points, so you can not get negative score.
Shortly after releasing Leagues, Pixonic made new scoring system, where everybody on losing team is loosing points, and everybody on wining team gaining a lot of points; new system is shown in table below:
