I would like to be able to start up multipli window forms

I have a game. Every game will only take 5 players. So I thought if the user would get a startup form.....asking how many players. There they might enter 7 players. Then I would like two game windows to open. That will say.....one with 5 players and one with 2 players. Is that possible?

WIll it be something like.... but with a for loop???
private void ok_Click(object sender, System.EventArgs e)
 {

    MyGame mygame = new MyGame();
mygame.Show()

}
