As an example, let's use a Yankees-Red Sox game with a total of 10.5 and odds (or juice ) of -120 to the Over and +100 to the Under. If you place aR$100 bet on Over 10.5, you stand to collectR$183.33 (originalR$100 bet, plusR$83.33 in winnings).
Specifically, over 1.5 refers to a bet on the total number of goals scored in a match. In soccer, for example, if you place an over 1.5 bet, it means you are predicting that there will be two or more goals scored in the match.
