The final three games of qualifying for the 2018 World Cup take place on Tuesday.
Already qualified: Mexico, Costa Rica
Places to be decided: 1 automatic, 1 intercontinental playoff
Here, we take a look at which nations can still make it to Russia, and how they can get there.
The top three teams qualify directly, with the nation that finishes in fourth facing a two-leg playoff against either Australia or Syria for a place at the finals.
Mexico and Costa Rica are through so it comes down to a fight between Panama, United States and Honduras for the last automatic place and the playoff berth.
3 (automatic). United States, 12 (a-Trinidad and Tobago)
Win: Guaranteed to qualify
Draw: As Panama's goal differential is seven worse, and Honduras' 12 worse, United States is all but assured of a place with a draw
Lose: If either Panama or Honduras wins, then United States drop into the playoff. If both win, United States would be out.
SPI chance to qualify: 93 percent
4 (playoff). Panama, 10 (h-Costa Rica)
As its goal differential is five better than Honduras, it only needs to match the result of its rival.
Win: Earns the playoff (and automatic if United States loses).
Draw: Is good if Honduras draws or loses
Lose: Only good enough if Honduras loses too.
SPI chance to qualify: 41 percent
5 (out). Honduras, 10 (h-Mexico)
That late leveller away to Costa Rica has made its job harder. It now has to get a better result than Panama just to make the playoff.
Win: It needs Panama to lose or draw (would go through automatic if United States loses too).
Draw: It needs Panama to lose.
Lose: Can only make the playoff if Panama loses by five more goals.
SPI chance to qualify: 11 percent
