Well, I cant decide which rules will be valid here on TUS. I have just told what I know from my experience with BnG. I agree on everything Wooka and Green wrote, I would just change pilling (distance between worms) rule, and add 'no repeating shots' rule. I have told my opinion before.
Agrees - disagrees?
Anyway, I'm just trying to help here, I doubt I'll even play a league (I ain't fan of leagues). But I like BnG scheme mostly and I hope it will be played on 'decent level' in future, that's why I suggest this.
U choose.
