In betting, an ‘over’ is a type of wager where you bet on the sportbook’s own predictions. The term can be explained like so: - a bookmaker first sets a prediction for a certain match outcome (usually the game point total) - you bet whether the total points or goals scored is either over or under the bookmaker’s prediction - if you think the team are going to score more points than the total, you’re betting over - if you think the opposite (that the team are going to score less points than the total), you’re betting under It is known as totals betting or over/under betting, depending on the country
