Polo is not played exclusively on horseback. Such polo variants are mostly played for recreational or tourist purposes; they include canoe polo, cycle polo, camel polo, elephant polo, golfcart polo, Segway polo and yak polo. In the early 1900s in the United States, cars were used instead of horses in the sport of Auto polo. Hobby Horse Polo is using hobby horses instead of ponies. It uses parts of the polo rules but has its own specialities, as e.g. 'punitive sherries'. The Hobby Horse variant started 1998 as a fun sport in south western Germany and lead 2002 to the foundation of the First Kurfürstlich-Kurpfälzisch Polo-Club in Mannheim. In the meantime it gained further interest in other German cities.
