Over/Under markets consist of predicting whether a total match statistic (goals, cards, corners, points, etc.) will be higher (Over) or lower (Under) than a specific number.
Why is .5 used?
Keep in mind that in a match, goals, cards, and corners are always whole numbers (0, 1, 2, 3...). You will never see a match with “2.5 goals”.
That is why when a betting line includes .5, the actual result will always be clearly above or below that line, making it immediately clear whether your bet wins or loses.
In short, .5 is simply a reference point that makes it 100% clear whether you went over the number (Over) or stayed below it (Under), with no room for uncertainty.
How do you determine if you win or lose?
Simple rule: compare the actual result with the line.
- If the actual result is higher than the line → Over wins.
- If the actual result is lower than the line → Under wins.
Goal examples
- Over 2.5: you need 3 goals or more to win.
- Under 3.5: if the match ends with 4 goals or more, you lose.
Card examples
- Over 4.5 cards: you need 5 cards or more to win.
- Under 5.5 cards: if the match ends with 6 cards or more, you lose.
Quick rule
Round up or down to the whole number you need to exceed or stay under:
- Over 2.5: you need 3 or more.
- Under 2.5: you need 2 or fewer.
- Over 3.5: you need 4 or more.
- Under 3.5: you need 3 or fewer.
Why is a bet with a .5 line never voided?
Because the actual result (a whole number) can never be equal to a line ending in .5.
The result will always be clearly above or below the line, so there is always a defined winner, regardless of how close the final result is.
