A Split Ball handicap, otherwise referred to as a Quarter Ball, is the level of favoritism between a half ball and a whole ball. Here, your stake is split equally between the whole ball and half ball handicaps. If you place aR$100 wager on Team A -1.0,-1.5, then your wager is split into twoR$50 wagers.
