As great as legendary soccer stars like Ronaldo and Messi have been on the pitch, none have ever been able to half -score! That eliminates the complication of 'push' outcomes where bets are returned due to total goals-scored in matches equaling O/U totals. However, the Over/Under soccer lines at FanDuel are halved fractions with a decimal, like (1.5) or (3.5). FanDuel's goal total, or 'Over/Under' markets include popular 'optional' O/U lines, with separately-handicapped odds attached to each Over and Under pick. Sometimes a bettor's need for variety complicates the odds. Whole numbers, and easy-to-understand odds, are no longer accurate models of the likely outcome. But if the same Thoroughbred has a winning streak leading up to Churchill Downs, and handicappers find that its chances of winning are 5 out of every 12 simulated Kentucky Derby races, the odds must comply with the fraction. Bookmakers can feel confident giving the horse 10-to-1 betting odds, or 9-to-1 odds if the book is including a standard house percentage. Suppose a Thoroughbred has a 1-in-10 odds to win the Kentucky Derby. Sports betting odds are not always simple, and though sportsbooks rarely try to make things difficult, the nature of sports themselves causes the gambling odds to be complex.
