The Round Rock Multipurpose Complex will host the 2018 U.S. Quidditch Cup, the 11th national championship for the "Harry Potter"-inspired sport, on April 14-15, 2018.The new sports complex opened May 18 and has 10 soccer fields, two of which have scoreboards and bleachers to accommodate the championship games. Tickets will be available in the fall.Austin is home to two national championship-winning teams: Texas Cavalry and Texas Quidditch. Texas also has the most registered Quidditch teams of any state, according to U.S. Quidditch, the national governing body for the sport.The cup will be split into two divisions, a collegiate division and a community division. Both divisions will compete at the same regional and national events, but collegiate teams will only play against collegiate teams and community teams will only play against community teams. Teams must qualify through regionals to compete for the national crown.Based on the beloved book series by J.K. Rowling, Quidditch is a mixed-gender sport best described as a mix between rugby, basketball and dodgeball with broomsticks added to the mix. Whereas in the books witches and wizards fly on broomsticks to play the sport, the muggle—or human—version requires players to hold a broomstick between their legs throughout the game. Players score by throwing one of the balls through one of three rings at the opposite end of the field.2017 also marks the 20-year anniversary of the book series, and Austin is host to several "Harry Potter"-themed events throughout the year that will tide fans over until the Quidditch Cup.“We are honored to host the players, families and fans in Round Rock for the U.S. Quidditch Cup in April 2018,” Round Rock Convention and Visitors Bureau Director Nancy Yawn said in a release. “How exciting that the year of the 20th anniversary of Harry Potter, the Sports Capital of Texas gets to announce that the magical, competitive Quidditch national championships will be held here!”
