Racquetball is primarily popular in North America, with the United States being a leading nation. It's played indoors on a court with a small, bouncy ball and a stringed racquet. The sport is known for its fast-paced and intense nature, requiring good reflexes and stamina. What makes racquetball special is the high level of physical activity involved and the strategic depth of the game, which can be played both recreationally and competitively.
