Well the logic behind it isn't consistent.
There are two different systems at play with the coin mobile matches.
Regular Coin Matches that apply to Division
Losses: No change to points.
Ties: you get your bet back but it doesn't count towards points.
Wins: You get points equivalent to total pot minus the vig.
Turf War Scoring
Losses: no effect on points.
Ties: You get your bet back AND this counts as equivalent points for turf war.
Wins: You get points equivalent to total pot minus the vig.
When playing a Turf War game both systems are in play. But for different rankings.
There are some things about it that aren't intuitive but it's their point systems.
Interestingly if you were a 50% winner. You would show an increase in both scoring systems but actually lose coins due to the vig.
