The Tennis World Cup comes back after a six-year absence and with a completely new format. The first new edition will take place from 16 to 22 July 2018 just after Wimbledon, at the Madison Square Garden in New York. It will be an inedited format, with every tie featuring four matches: women's singles, men's singles, mixed doubles and especially mixed singles.
Each match is divided into four quarters of 20 minutes each, totalling 80 minutes. The winner of the match is the nation that has won the most games during that time period. The team who will have won more games at the end of the tie will win.
