You should definitely make us put in the name of the tournament instead of the city because it makes it harder for people who know the tournaments well but only by name. But good unique quiz anyway
I think it is hard enough to remember all the locations as it is. Do you really expect people to also know the exact titles of all the tournaments? A lot of them have their sponsors included, like Banque Eric Sturdza Geneva Open, or Fayez Sarofim & Co. U.S. Men's Clay Court Championship - or, one on the WTA calender called Grand Prix De SAR La Princesse Lalla Meryem. If you want to memorize all those names, good luck.
P.S: And? Do you know the locations of those last ones?
