Tennis is played in over 200 countries and the four Grand Slam tournaments attract a combined audience of over a billion viewers annually. This quiz covers the sport's greatest champions, iconic rivalries, and the rules that make tennis unique.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll discover who holds the most Grand Slam titles, learn how the unique scoring system works, and explore the differences between the four major tournaments. Did you know that Wimbledon still requires players to wear almost entirely white clothing?
Novak Djokovic holds the men's record with 24 Grand Slam singles titles. Margaret Court holds the all-time record with 24 (in the women's game), while Serena Williams won 23 in the Open Era. The rivalry between Djokovic, Federer (20), and Nadal (22) defined a generation.
Tennis uses a unique scoring system: points go 0 (love), 15, 30, 40, then game. A player must win by two points — if tied at 40-40 (deuce), play continues until one player leads by two. Sets are won by the first to 6 games (with a tiebreaker at 6-6 in most cases).
The four Grand Slam tournaments are the Australian Open (January, hard court), French Open/Roland-Garros (May-June, clay), Wimbledon (June-July, grass), and the US Open (August-September, hard court). Winning all four in one year is called a Calendar Grand Slam.
