The system used (Cascadia) awards points based on 3 differents factor :|
1) cumulative number of center year by year divided by a factor which grows faster and faster (grow big, and fast. In very long game every new year might decrease this score).
2) outcome bonus (2-way, 3-way, etc.)
3) topping bonus (only if there is no tie)
Typically, 1) gives the most point. 2) & 3) are around 1pt.
