[4][5] Previously the competition was only open to couples consisting of men and women but in 2013 the rules were relaxed to allow same gender couples (man dancing with man, or woman with woman) to enter[6] the competition.
The same wildcard advantage is also given to national or regional champions of recognized competitions; These include Uruguay (UY), Chile (Cali, CL), Colombia (Bogota, CO), Brazil (Rio de Janeiro, BR),[7] USA (San Francisco, US), Russia (Moscow, RU), China (Nanjing, CN), Japan (Tokyo, JP), Korea (Seoul, KR), France[8] (Paris, FR), United Kingdom (London, UK), EU (Campeonato Europeo, Italy).
[13] A closely related and highly influential event is the Buenos Aires City competition.
The competition rules[14] state that members of the couple must both have "DNI" (i.e. have a resident status of 2 years or more) in Argentina.
Only couples Carlos Estigarribia & María Laura Sastría (2015) and Jimena Hoffner & Fernando Carrasco (2008), have won the triple championship.
Couples in positions 2 through 5 are granted direct access to the semifinals in Mundial de Tango.
The City competition's winners and runners-up are likely to become highly regarded and sought out teachers worldwide.
[15][16][17] In 2015 the milongas of Buenos Aires (El Fulgor de Villa Crespo, Salón Canning, Salón El Pial, Club Sunderland, Club Ciencia y Labor) started arranging monthly competitions whose final culminate in December.
The two monthly winning couples are voted for qualifying rounds and final by the audience and not selected judges.
