This market asks whether the total for a specified event will exceed or stay below a given line. Depending on the sport, the total may cover goals, points, games or another statistic. On some whole-number lines, landing exactly on the line can produce a push and return the stake, subject to the market rules.

Over/Under markets are useful when pace, intensity or efficiency matters more than the identity of the winner. They turn an assessment of attacking output, defensive resistance or match tempo into a specific projection. They also provide a clear bridge between statistics and a bettable scenario.

With an Over/Under 2.5 Goals line, a 2-1 score settles the Over because the match contains three goals. A 1-1 score settles the Under because it contains two.
