With the final round of group fixtures now under way the path to the World Cup final on 19 July is starting to take shape.
But with 32 of the 48 teams advancing to the knockout rounds, new tie-breaker rules, and a table of third-placed teams to keep track of, staying across the various permutations is far from simple.
As it stands, England, sitting top of Group L, and Scotland, who finished third in Group C, would be on the same path to meet in the last 16 in Mexico City (6 July, 01:00 BST) – but they would have to win last-32 ties first.
But Scotland’s 3-0 defeat by Brazil has left their hopes of going through as one of the best third-placed countries hanging by a thread.
There is lots still to be decided, so find out the results required to get teams through to the knockout rounds.
BBC Sport has also developed a projection tool that updates in-game to illustrate the schedule all the way to the final.
With dates and times listed alongside the fixtures, planning early morning alarms and potential all-nighters across three host countries and four different time zones has never been easier.

How does knockout qualification work?
Sixteen of the record 48 teams involved in the World Cup will be eliminated at the end of the group stage, leaving 32 nations in the mix for the trophy.
The top two teams from each of the 12 groups will advance to the last 32.
The remaining spots in the knockout stages are taken by the eight third-placed teams with the best records.
If two or more countries are level on points, head-to-head results are used as the first tie-breaker to determine positions.
If the teams remain tied, they are ranked on goal difference, goals scored, Fifa’s Team Conduct Score – a disciplinary metric for red and yellow cards, and finally whoever had the higher Fifa ranking in June’s published update.
These criteria are applied in the 12 groups of four and to determine the rankings of the 12 third-placed sides.
Group A
Co-hosts Mexico became the first nation to qualify for the knockout stage and won Group A with a 100% record.
El Tri will host a third-placed team from Group C, E, F, H or I in the last 32 on Tuesday.
South Africa beat South Korea 1-0 in their final group stage game to climb into second place and reach the knockout stage for the first time. They will play Canada in the last 32 in Los Angeles on Monday.
That result meant South Korea finished third in the group with three points and they must wait to see if that is enough to send them through.
Czech Republic‘s defeat to Mexico meant they finished bottom of the table with one point from their three matches.
Group B
Switzerland won the group on seven points with a 2-1 victory over Canada.
The Swiss clinched a last-32 tie against a third-placed team in Vancouver on Thursday, 2 July.
Canada finished as runners-up on goal difference with four points and face a date with South Africa in Los Angeles on Monday.
Bosnia-Herzegovina beat Qatar 3-1 to finish third on four points.
South Africa’s win over South Korea confirmed Bosnia would be one of the best third-placed teams.
Group C
Five-time winners Brazil topped the group on goal difference with seven points thanks to their 3-0 win over Scotland. They now play the runners-up of Group F in Houston on Monday.
Morocco went through in second place on seven points after they beat Haiti 4-2. The North Africans’ next opponents will be the winners of Group F in Monterrey on Monday.
Scotland finish in third on three points and goal difference of -3, which Opta says now gives a 38% chance of qualifying.
Steve Clarke’s men now face an anxious wait to see if they will get another game, or will head home. It might be a close run thing.
Haiti were already eliminated without scoring a point.
