Over-Under Betting Definition

Over/under betting involves the punters betting on a number of goals, corners, yellow cards or other events in a match.

They don’t need to guess the correct number of the aforementioned events, but rather whether the final number will be over or under the line set by the bookmaker.

Over/under 2.5 goals is the most common market as far as the football matches are concerned, meaning that you can bet on over 2.5 goals to be scored (you win if there are three or more goals scored) or under 2.5 goals (you win if there are two goals scored or less).

There are just two possible outcomes in over/under betting, which significantly increases the winning chances.


A player places a £100 bet on over 12.5 corners to be taken in a match. If there are 13 corners taken or more, the bet wins and if there are 12 corners taken or less, the bet loses.
