Squash is a popular global racquet sport played by two (singles) or four players (doubles) in a four-walled court with a small, hollow rubber ball. For its fast pace and requirement of mental agility, it has been described as "jet-propelled chess". In 2003, Forbes rated squash as the number one healthiest sport to play. The game was formerly called
squash racquets, a reference to the "squashable" soft ball used in the game.
