First, read the English article below.

Standard bocce sets contain 8 colored balls — 4 balls each to a color, typically green and red — and one smaller ball, called the jack or pallino.  Different skill levels are often associated with different sizes of bocce balls. Smaller balls tend to be used by beginners and kids, while the larger ones are used by professionals. Regulation-sized bocce balls have a standard diameter of 107 mm (4.2 inches) and a standard weight of 920 g (~2 lbs).  Standard bocce sets will run you at least $20, but if you're going to buy a professional set, you could need more than $100. Bocce ball can be played by two single players pitted against one another, or by two teams with two, three, or four players each. Teams of 5 or more are not advisable, as fewer balls than players means that not everyone will get a chance to bowl. " If you don't have a bocce court, you can always play in open space, although a defined court is preferred. A regulation court is a maximum 4m (13 feet) wide and a maximum 27.5m (90 feet) long, although any rectangular court measuring about 13'x90' should do.  Regulation bocce courts have a raised barrier around the edge of the rectangle. In most cases, this raised barrier measures a maximum of 20 cm (~8 in) high. Mark a foul line, if not already given, beyond which players cannot step as they bowl a bocce ball. Some players prefer to pound a regulator peg in the exact center of the court. This is the point beyond which the jack or pallino must pass when it is thrown out at the beginning of the game. This is one variation of how many people play bocce, although it is not standard.
