A little late perhaps, but after some discussion of the rules of pétanque yesterday, here are the Australian rules for the game. They are extensive and fairly prescriptive. These rules are based almost totally on the Official International Rules.
The Wikipedia entry on pétanque is both interesting and informative.
I found responses to some specific queries raised on the day:
- both feet must be within the circle - Australian rules;
- valid distances for the thrown jack are 6 metres minimum to 10 metres maximum - Australian rules;
- boules are thrown underarm (no requirement to throw with the "palm down") - Wikipedia.
