As of March 2024, the FIPJP rules governing the petanque jack (the little target ball, cochonnet, bouchon) are as follows. Note that the written FIPJP rules do not describe them this way. But taken all together, this is what the written FIPJP rules, in their current state, boil down to. Detailed information is provided in the body of this post.
