Hardball squash is a format of the indoor racquet sport squash which was first developed in North America in the late 19th century and early 20th century. It is sometimes referred to as being the "American version" of the sport. Compared to the "British version" of the game—which today is usually referred to as being the "international" version, or "softball" squash—the hardball game is played using a harder rubber ball which plays faster, and usually on a smaller court for singles play, or a much larger court for the doubles game.
