Roque at the 1904 St. Louis Summer Games:

Roque is a variant of the sport croquet, and the name is derived by dropping the initial "c" and the trailing "t" from the name of the sport, croquet. It was contested at the 1904 Olympics as part of the program at the Louisiana Purchase Exposition. However, no foreign athlete competed or entered. In addition, the championship doubled as the United States National Championship. The events were organized by the leading exponent of roque in this country, Charles Jacobus of Springfield, Massachusetts. Jacobus was the author of the Spaulding Official Roque Guide and was the president of the national association in 1904. He had been national champion in 1885.

Four athletes competed in the 1904 "Olympic" roque. Jacobus won the competition which was contested as a double round robin with each athlete playing a match against the other athlete twice.
