Our leagues use an 8 point system:
2 points per game = 6
2 points for total pins (series) = 2
Ties are 1 point each.
I'd prefer the 24 or 30 point system myself, but the odds of getting bowlers to change in leagues here is nearly zero. A 30 point system was presented to the highest average league here some time ago and as simple as that scoring system is, there were those who claimed that they couldn't understand it. So it was voted down. I think the scoring systems which have some head-to-head features mixed in, help to lessen sandbagging to a degree.
