You might be thinking: What is the Ultimate Tennis Showdown? Is it gladiators playing tennis? Is it a video game come to life?

The brainchild of Patrick Mouratoglou, UTS is a no-audience, live-broadcasted tennis competition that pits top players against each other every weekend for six weeks. Players include Dominic Thiem, Stefanos Tsitsipas, Matteo Berrettini, Dustin Brown, Feliciano Lopez, Benoit Paire, Alexei Popyrin, Lucas Pouille, Richard Gasquest and David Goffin.

The format is very different than the traditional match structure of the ATP and WTA Tours. How different? Well, you'll have to take the quiz and find out.
