There are courts available for commercial play in conjunction with bowling alleys in Rome, New York and you can settle your dinner over a game at restaurants in Boston and Manhattan. You can vacation in the Catskills at resorts with bocce courts being a primary activity. There are courts in senior housing communities, recreation centers, bocce clubs, Italian clubs and fraternal clubs as well as many private yards. And if you can't find a court, keep your eyes open. You might just find a game in a playground or open field somewhere.
Rules differ greatly, just as they do throughout the rest of the country.
It depends on the home court and tournament organizer. Games are played on 60 foot courts and 85 foot courts. Some versions require that you call your shot, others do not. Some balls are punto raffa volo size, some are larger, but there are very few metal balls. Most versions alternate ends of the court, some have two teammates permanently stationed at each end of the court for the duration of one game.
