Over/Under (also known as Total Betting in English) is one of the most common types of betting markets in sports wagering. It involves predicting whether the total score of a match will be higher or lower than a specific number set by the bookmaker, rather than predicting which side will win. This type of wager is popular in football, basketball, American football, baseball, and more — especially among players who prefer focusing on scoring pace rather than match outcomes.
Gameplay Logic Explanation
| Item | Description |
|---|---|
| Bookmaker's Projected Total | The platform sets a predetermined score line (e.g., 2.5 goals, 210.5 points). |
| Player's Betting Direction | The player chooses to bet on “Over” or “Under” relative to the line. |
| Win/Loss Determination | After the match, if the actual total exceeds the line, “Over” wins; if it is lower, “Under” wins. If it’s exactly the same, a push/refund may occur depending on the event rules. |
