The FIPJP rules of petanque are designed for use in FIPJP-sanctioned competitions supervised by FIPJP-certified umpires. In addition to being unclear and sometimes unfair when strictly interpreted, the FIPJP rules are dependent on the presence of an umpire to the extent that, under some circumstance, they are useless in friendly games. By “friendly games” I mean games played outside of an organized competition, without an umpire.
In response to these problems, the Petanque Libre Project has developed an alternate set of rules for the game of petanque. The Petanque Libre rules are designed with friendly games in mind; they are designed so that ordinary players can understand, interpret, and apply them in games played outside of an organized competition, without an umpire.
You can read more about the project, and download a copy of the rules for Petanque Libre, at the Petanque Libre Project website. The project has also issued a Request for Comments on the rules.
