In a Mix Americano you play an Americano with the same number of women and men. In each round, a woman and a man will meet another woman and man.
The app automatically draws lots so that all sets of men and women can play with each other.
The app currently supports up to 16 participants in the mix. Mix can also be used to mix really good players with beginners so that a beginner can always play in the same team as an experienced one. Then you enter either the beginners or the experienced as either gender in the app.
May the best person win!
