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. Some areas allow side wall bank shots and back wall to remain live if your bocce hits it, while others would call that a dead ball and remove it from the play. Some courts have angle boards placed in the corners to allow the players to additionally use those angles much as you would in billiards. On other courts where the back wall is live, it is a swinging board which deadens the impact for a bounce back out into the playing field. There are courts that used to have the swinging back boards which have been removed, and courts that have removable corner angles.
