When you bet on either an under or over 1.5 goals market you will be betting on a football match to ever more or less than 1.5 goals scored throughout the game.
If you bet on an under 1.5 market you are predicting that there will be less than 2 goals in the game. Your bet selection will win if there are 0 or 1 goals in the match.
On the other hand, if you bet on over 1.5 markets then you are making a prediction that there will be 2 or more goals scored during the match. These can be scored by either team.
Are there any rules I need to be aware of?
Yes. Some bookmakers may have clauses that the goals will only count within the 90 Minutes (+injury time). This means that if a goal is scored after the final whistle then it will not count towards the outcome of your bet. An example of this would be that goal scored in extra time or penalty shootouts will not count.
