Over Under 2.5 is the most traded goals line in football because the average match lands near that number. Over wins with three or more goals, Under wins with two or fewer, and the winner of the match is irrelevant.

The half goal exists to avoid a tie. Whole lines like Over 3.0 can refund on exactly three goals, and quarter lines split your stake, so reading the exact line on your slip matters as much as picking Over or Under.
