its this weird game they play in third world countries it mainly involves your foot and that ball they juggle the ball on their foot and try to kick it through a goal post to win the game but if they stop running then they lose
the advance / knockout round is win or lose, group stages you go for points, top 2 of the 4 team group move on to knockout round. in group play you play the other 3 teams once and get 3 pts for win 1 pt for tie 0 pts for lose, and again top 2 move on to knockout round
