How to Get Sports Betting Odds and Lines: A Full Guide

American Odds: The +/- Rule
Sports betting odds vary in style, and American odds are most used in the US. These odds have a plus/minus rule to show bettors their possible win. If you see -150, you must bet $150 to win $100. On the other hand, +150 means you make $150 on a $100 bet.
What Decimal Odds Mean
Decimal odds show what you get back for each dollar bet, counting your first stake. A 2.0 decimal line gives you $2 for every $1 bet. This method is liked in European areas and makes figuring out what you’ll get back easy. 공식 검증 방법 보기
Point Spreads and Their Changes
Point spreads make both sides in a game look even, even if one team is better. The top pick gets a negative spread (-7.5), and the less liked team gets a positive one (+7.5). These numbers are set by oddsmakers to get equal bets on both sides.
How to Change Odds Types
Knowing how to switch odds between types is key to find good bets. To change American odds to decimal ones:
- For + American odds: (American odds / 100) + 1
- For – American odds: (100 / (abs(American odds))) + 1
Figuring Out What Odds Suggest
Implied probability is what the odds think will happen. To find this:
- For + American odds: 100 / (American odds + 100)
- For – American odds: (abs(American odds)) / (abs(American odds) + 100)
How to Spot Good Bets
Value betting is when real chances are better than what the odds say. Good bettors use numbers and deep market checks to find these in the betting world.
American vs. Decimal Odds: The Full Guide
Big Differences in Betting Forms
Sports betting odds show up in different ways all over, with American and decimal odds being top types worldwide.
What American Odds Are
American odds use a plus/minus rule usual in US betting. The numbers show as either + or -:
- Negative ones (-150) show what you need to bet to win $100
- Positive ones (+150) show what you win on a $100 bet
Decimal Odds Style
Decimal odds, mainly in Europe and Australia, show total back on a $1 bet, including your first stake.
This style is simple to work out:
- Total Back = Bet × Decimal Odds
- For instance: $100 × 2.50 = $250 total back
Switching Between Types
From American to Decimal
Turning – American odds:
- Way: (100/odds) + 1
- For example: -150 becomes 1.67
Turning + American odds:
- Way: (odds/100) + 1
- For example: +150 becomes 2.50
These ways let bettors match odds well across different markets and spots, making sure they bet well.
Checking Point Spreads
Point Spreads in Sports Betting: Simple Facts
Basic Point Spread Facts
Point spreads show the guess win gap set by oddsmakers to even out bets.
With a spread at -7.5 for the top pick, they must win by 8 points or more for bets to pay.
For the less liked at +7.5, bets pay if they lose by 7 points or less or win the match.
Important Numbers for Bets
Big numbers are key in sports betting, more so in NFL bets.
Scores often end on 3, 7, or 10 points because of how points are made.
Getting a +3.5 spread rather than +3 is key because 3-point ends come up a lot in games.
Spreads and Where Games Are
Half-point spreads (or “hooks”) stop bets from being a tie where money comes back.
Home-field pull often adds about 3 points to spreads in pro sports, but this changes with the league and place.
Smart bettors think about where games are and past scores when they look at spreads.
Deep Spread Checks
Expert bettors study line changes and how many bet on each side to find good bets.
Knowing line moves that go the other way and signs of big money helps find the best spots to bet.
First lines versus last spreads often show key market tips for smart betting choices.
Moneyline Betting: The Basics
Moneyline Betting Made Simple

Moneyline Betting Basics
Moneyline betting is all about picking who wins, straight up.
Unlike spreads, how much they win by doesn’t matter in moneyline bets.
The odds show as plus and minus numbers, like +150 or -180, telling both team chances and what you could get back.
Reading Moneyline Odds
Minus moneyline numbers (-180) point to the favored team and say how much you must risk to win $100. For instance, a -180 moneyline calls for a $180 bet to maybe win $100.
On the flip side, plus moneyline numbers (+150) show the underdogs and what you’d win on a $100 bet – here, $150.
Smart Uses
Moneyline betting works well in low-point games like baseball and hockey, where spreads matter less.
The clear cut way of picking winners makes moneyline bets liked by new and long-time bettors.
Working Out What You Could Win
To see possible wins on moneyline bets:
- For favorites (minus odds): Divide 100 by the clear moneyline number, then times by your bet
- For underdogs (plus odds): Times your bet by the moneyline number, then divide by 100
Add your first bet to the figured profit for total possible back.
The Basics of Over/Under Totals Betting
Over/Under Totals Betting: A Full Breakdown
Over/Under Betting Basics
Over/under totals betting is all about the final score sum of two teams in a game.
Bettors guess if the final score will be over or under a number set by oddsmakers. This bet type needs strong stat checks and thinking about many sides.
Crucial Stats to Check
The heart of good totals betting lies in looking at key numbers:
- Team point averages
- How well teams stop others from scoring
- How fast teams play
- Past scores when teams met before
Thinking About the Game Type
NBA Totals
When looking at an NBA game with a total of 220.5, think about:
- How much teams score on average
- How good they are at stopping others
- Recent scoring trends
- How quick teams play
Outside Game Parts
Weather means a lot in outside games:
- Baseball: How wind moves
- Football: How wet or cold it is
Studying Line Changes
Knowing how lines move gives key betting hints:
- First total set
- Big money effects
- Market changes
- How many bet on each side
What Impacts Totals
Many parts change game totals:
- Team plans (games back-to-back, rest times)
- Key player hurts (how they score and stop scores)
- Where they play
- Past games
How to Work Out What You Might Get
Getting Good at Sports Betting Math
Odds Types and What You Might Get
Doing well in sports betting means getting your math right on different odds types.
Exact number work is key to good bet plans and handling your bet money.
American Odds Math
Changing American odds goes two ways:
- For + odds (+150): Divide by 100 to see profit on a $100 bet ($150 profit)
- For – odds (-150): Divide 100 by whole odds value ($66.67 profit on $100)
Decimal and Split Odds
Decimal odds math needs you to times your bet by the decimal number (2.50) to see total back, then take off the first bet for profit.
With split odds (3/1), times the bet by the split for profit, then add the first bet for total payout.
Deep Bet Math
Knowing the house take (often 4.55%) is key to see expected value.
To make money with usual -110 odds, bettors need a 52.38% win rate to get even.
Keeping track of your numbers helps you see if you’re doing well and change your plan as needed.
Making the Most of Number Checks
Pro bettors mix these math ways with:
- Guessing chances
- Risk plans
- How to spread money
- Keeping track of past tries
Getting these math skills right builds a strong base for making money plans and keeping wins over time.
How to Spot Good Bets
Getting the Best from Betting Lines
Stats Checks and Market Gaps
Good value bets are found when what’s likely doesn’t match what odds say.
Deep checks need looking at old numbers, team stats, and game parts that bookmakers might not see.
Checking Rating Gaps
Ratings from many places show gaps in the market.
When numbers say a team has a 60% chance to win but odds give 52%, bettors find good bet chances.
Work out possible value by timesing expected win chance with possible payout and taking off the bet.
Using Market Parts
Outside Parts
Weather changes, team hurts, and team will give chances where most don’t see change fast enough. Sharp bettors watch these to make money before odds move.
Line Checks
Watching line moves and big money signs gives hints about the market.
When books give -110 versus -120 on the same thing, bettors use chance differences through smart number checks. How Sportsbooks Set the Odds
