Over 2.5 goals is a betting market which relates to the number of goals that will occur in a football match. So for a game to go over 2.5 goals, three or more goals need to be scored, 3.5 is four or more so on and so on.
When playing the over 2.5 market It doesn’t matter if the game ends 3-0, 0-3, 4-2,
3-1, 2-1 or 1-2. As long as the total number of goals exceeds three or more, the game would have ended with over 2.5 goals.
The over/under totals are set at 0.5 intervals to ensure that a bet will produce a result. In other words, the total number of goals scored in a match will always be over or under the specified margin as you can't score a 0.5 goal.
The best part?
No longer do you have to pit two teams against each other instead when you bet on the goal market the two teams are working together to provide you with betting profits.
Why only over markets?
More from a watching perspective, nobody wants a game to be low-scoring and when you play the under goal markets you are essentially wanting a boring game with not much action at either end, therefore ruining the enjoyment of the beautiful game we all know and love.
