Making a minigame rounds

I'd like to make my minigame rounds
example: when blue team won the 1st round, the game will continue to 13th rounds, the more scores is the winner . just like Counter Strike hehe

 

Like this?

PHP:

private $wons = ['red' => 0, 'blue' => 0, 'continue' => 10];

public function onWin(string $team){
   $this->wons[$team]++;
   if($this->wons[$team] >= $this->wons['continue']){
      //TODO you must stop the game. 
   }
}
