And it would be possible to shorten the elimination, e.g.
South America - 10 teams (according to regulations) - 4 teams will advance to the World Cup, the fifth game will play-off intercontinental.
Europe - 55 teams (according to regulations) - 13 teams will advance to the World Cup, 10 group winners + 3 teams from two-level play-offs (12-> 6-> 3).
Asia - 24 teams (last three rounds - 6 groups x 4 teams, 2 groups x 6 teams, play-off teams from 3 places for play-off intercontinental) - 4 teams will advance to the World Cup (+ Qatar as host), the fifth game play intercontinental play-off.
Oceania - 6 teams (the last three rounds - 2 groups x 3 teams, semi-finals, final, intercontinental play-offs) - the winner of the elimination game intercontinental play-off for promotion to the World Cup
Africa - 20 teams (last round - 5 groups x 4 teams) - 5 teams will advance to the World Cup.
North and Central America - 12 teams (the last three rounds - 3 groups x 4 teams, 1 group x 6 teams, intercontinental play-offs) - 3 teams advance to the World Cup, the fourth game intercontinental play-off.
It gives 127 teams a part in the tournament ... I would like to do it but I can't do it alone ...
