Instead of taking a breather, the USA created a World Cup math puzzle for its fans back in America. The USA would advance to the knockout stage with a win or a tie against the Germans, or a draw between Ghana and Portugal. If there's a winner in the other game, the Americans also could advance with four points on a tiebreaker: goal difference, followed by total goals, head-to-head points, head-to-head goal difference and head-to-head goals. If a tie still isn't resolved, there would be a drawing of lots.
