overandunder

Over/under, also known as totals, is a type of sports wager where a bookmaker sets a total number of points, goals, or runs expected to be scored in a game. Bettors decide whether the actual combined score will exceed the stated total (over) or be less than it (under). If the game ends with a score that matches the total exactly, the bet is often a push and the stake is returned, particularly when the line is a whole number. To reduce pushes, bookmakers commonly use halves in the line (for example, 214.5).

Example: In a basketball game, the over/under might be set at 215. If the final combined score is 110–105 (215), that is usually a push. If the score is 111–105 (216), the over wins; if it is 109–105 (214), the under wins.

Variations include team-total lines (betting on how many points a specific team will score), and in-game live totals that adjust as the game progresses based on pace and scoring. Some markets offer alternative totals with different risk/reward profiles.

Why people bet over/under: it provides a different angle from betting on the winner or margin of victory, can hedge another bet, and is influenced by factors such as pace, injuries, and intended strategy. Regulations and availability vary by jurisdiction and sportsbook, but the over/under remains a core component of many wagering menus worldwide.
