Over/under markets ask one question: how many? Goals in a football match, points in a basketball game, games in a tennis match. You do not need a view on the winner, only on the shape of the contest, which is why totals are the market most of our predictions use.
How the line settles
The most common line is a half number — over 2.5 goals — because it cannot be tied. Three goals or more and over wins; two or fewer and under wins. A whole line, over 3, can land exactly: three goals is a push and stakes are returned. Bookmakers offer both, and the whole line is usually a shade shorter on the side that would push.
Asian totals
Over 2.75 is half your stake on over 2.5 and half on over 3. Three goals wins the first half and pushes the second, so you get half a win. Over 2.25 is half on 2 and half on 2.5: two goals pushes the first half and loses the second. The quarter lines let the bookmaker set a price between the two whole numbers, and let you take a position that is not all-or-nothing.
Which line to take
If your view is “goals are likely” take the half line and accept the price. If your view is “three goals is the most likely single outcome” the 2.75 gives you a partial win on exactly that result. Only take the whole line when the push protects a position you genuinely want protected.
What settles the count
- Ninety minutes plus stoppage time in football. Extra time and penalties do not count unless the market says so.
- Overtime counts in basketball and American football unless the market says regulation only.
- Tennis game totals count every game played, including tie-breaks as one game; a retirement usually voids the bet, and the tennis retirement rules differ by operator.
Totals margins are the second-lowest in football at around 4.0% in our August measurement, and the main line on a big match is usually the sharpest number a bookmaker publishes. The line on a mid-table Tuesday fixture is not, which is where a view on the shape of a match can still find a price worth taking.
