What’s an Over/Under Bet?
Over/Under betting, also called totals betting, lets you bet if the teams’ total score will be higher or lower than what the oddsmakers say.
This type of bet lets you make money off game scores without needing to pick who wins.
How Over/Under Bets Work
Totals betting is very straight to the point. For instance, if an NFL game’s over/under is 48.5 points, you bet if the score will be over 48.5 (over) or under 48.5 (under).
That half-point makes sure each bet has a clear win or lose.

Reading Betting Lines
Knowing Betting Lines and Totals
Basics of Betting Lines
Over/under lines are core in sports betting plans.
A common line is like “O/U 47.5 (-110)” – where 47.5 is the guess, and -110 means you bet $110 to win $100.
Main Points in Totals Betting
Half-point odds stop tie scores.
To win an over 47.5 bet, the total score needs 48 or more. For under 47.5, it must be 47 or less.
The vigorish (vig) starts at -110 but can shift with how much is bet and where.
Reading Line Changes
Line moves show what the market thinks.
If totals change a lot, like from 51.5 to 48.5, it often means smart money is at work. Watching these moves is key to smart betting.
Knowing the Odds
We see -110 often, but it can change with the market.
If odds show as -120 for over and -100 for under, more people bet on the over. These odd changes show real betting moves and shifts.
Smart Tips to Read Lines
Good totals betting means tracking line moves and knowing why they happen. Smart bettors find value by acting early on lines and studying open and close numbers.
