Scoring is identical to that of tennis (15-30-40-game). In the variant called pallaventuno (or palla 21) each game counts as 7, and a set is won with three games (7 for the first, 14 for the second, and 21 for the third, hence the name given to the game). In the other variant, games are simply counted in progression (game 1, game 2). Pallacorda (or palla della corda) is an extinct form of the game where a cord was strung across the street. Pisa, Prato, Rome, Siena, and various Tuscan towns still have streets named "via Pallacorda" or "via Della Corda".
