By winning duels you will earn ranking points - cups.
The more cups you have, the higher in ranking you will be. Higher rank gives you better prizes for winning a duel.
Please note that you will lose cups if you lose or quit a duel.
You can view your place in your local and global ranking.
After earning 2500 cups you will be transferred to the time-limited rankings. Once the time is up, you will go back to having 2500 cups and the surplus number is counted toward your legend points. The more ranks you've won, the more legend points you'll have.
