The second round of the World Cup begins on Saturday, and the rules of the game change a little. The next stage is often referred to as “knockout round” because every match is lose-and-go-home.

Games that end in a tie go to overtime, which consists of two 15-minute periods with a short break in between. If a game is still tied at the end of overtime, the winner is determined by a penalty kick shootout—in which each team gets five penalty kicks and the one that converts the most wins. (In case of a tie in penalty kicks, each side kicks one more until the tie is broken.)

In any event, a number of teams have already qualified for the Round of 16, and a fairly clear picture of who will play whom can be drawn. Those that are through are: Argentina, Belgium, Brazil, Colombia, Chile, Costa Rica, Greece, Mexico, The Netherlands and Uruguay.
