How to obtain trophies
You gain trophies by winning matches. Thus you will lose trophies when you get defeated in matches. The lower your brawler’s trophies, the more you will gain and the less you’ll lose. For example, if your at 10 trophies on one brawler, you will lose close to 0 for a defeat and win around 7 for a victory. If your at 200 trophies, however, you will gain about 5 and lose about 5 per win and loss.
What to do with trophies
The best thing to do with trophies is to stare at how shiny they are. You can’t spend them for other things and they just sit here. The more trophies you have lets you brag to your friend about how much better you are.
