Every FBS school starts off with 100 marbles, plus 10 bonus marbles for every game on their schedule against a power conference opponent or Notre Dame
Beat your opponent at your home place or neutral site (including conference championships), take 20% of their marbles; beat your opponent at their home place, take 25% of their marbles
Fractional marbles are rounded to nearest whole number. For example, if you beat an opponent with 210 marbles at their place, you would get 25% of their 210, 52.5, which would be rounded up to 53.
If you beat an FCS opponent, you get nothing. If you lose to an FCS opponent, they get 25% of your marbles. Because FU coward.
