Can someone explain the round scoring system?

Hi there, played this game a lot and obviously understand the basic concept of winning a round, but what I have never worked out is how sometimes you can win a match 1-0 or 2-2 or whatever
Can someone explain the way the game tots up the rounds to give some teams an early victory or a win at 2-2 etc?

I think this needs clearing up in the game itself, with clearer match result reasons displayed.


The game currently is first to 3 wins.
However, the game will tie at 2-2 instead of going to 3. So max amount of rounds is 4.

Personally, I feel there shouldn’t be a tie and increase the game to first to 4 or 5. It doesn’t need to be as long as comp, but casual needs to last longer than it does now.
