If you're new to sports betting, consider this your first step into the sharp end of the pool. This isn't about picking your favorite team or player and hoping it hits, or following your gut. It's about understanding the numbers, reading the market, and making informed, disciplined bets.
Let's break down the fundamental bet types, teach you how to read American odds, and give you a strong foundation before we dive deeper in future guides.
The Three Core Bet Types
Before you can even think about line shopping or promo stacking, you need to get familiar with the basics. These are the three most common types of bets you'll encounter:
1. Moneyline Bets
This is the simplest wager to understand: you're betting on which team will win the game outright.
Example:
- New York Jets +180
- Buffalo Bills -220
The minus sign indicates the favorite. In this case, you'd need to bet $220 on the Bills to win $100. The plus sign shows the underdog. A $100 bet on the Jets would return $180 profit if they win.
It's important to understand that each line reflects implied probability. +180 looks juicy on paper, but it means the Jets are expected to win less than 36% of the time. Want to see the implied probability behind any price? Run it through our odds converter.
2. Point Spread Bets
The spread levels the playing field. You're not just betting who wins, but by how much.
Example:
- Cowboys -6.5
- Giants +6.5
If you take the Cowboys, they need to win by 7 or more. If you bet the Giants, they can win outright or lose by 6 or fewer.
Spread betting is a staple for sharp bettors. There's less juice on spreads than moneylines, which creates more opportunities for value. More on this later.
3. Totals (Over/Under)
You're betting on the combined score of both teams. Doesn't matter who wins, just how many points hit the board.
Example:
- Over 45.5 (-110)
- Under 45.5 (-110)
If the final score is 27-21 (48 points), Over bettors cash. If it's 20-17 (37 points), Under wins.
Sharp advice: Never bet the Under, it's un-American. Nothing says "I love football" like hoping nobody scores for 3 straight hours. With that said, the public typically bets the Over, which can create opportunities for Under bettors. Something to consider for later.
How to Read American Odds
If you're betting in North America, you'll be dealing with American odds. Here's the breakdown:
- Negative Odds (-110): You risk this amount to win $100. Standard juice on spreads/totals is -110. That means you need to win 52.38% of bets to break even.
- Positive Odds (+150): You win this amount on a $100 bet. So +150 returns $150 profit on a $100 stake.
Decimal Odds? You might see decimal odds in international markets (1.91 instead of -110). We'll stick with American odds throughout this guide, but our odds converter flips between American, decimal, and implied probability instantly if you ever need it.
Pushes and Value
- Push: If the spread or total lands exactly on the number you bet (ex: you bet Over 45 and the game ends 24-21), your bet is refunded. No win, no loss.
- Value: It's not about who wins, it's about whether the odds reflect true probability. You'll learn to sniff out mispriced lines in the Line Shopping guide, and our EV calculator does the math on any price you're weighing.
Juice (Vig): The Hidden Tax
Juice, also known as vig or vigorish, is the sportsbook's built-in edge. It's how they make money regardless of which side wins.
Example: A typical Over/Under or point spread will be listed at -110 on both sides. That means you need to risk $110 to win $100. The extra $10 is the juice.
This might not seem like much, but over time it adds up. To break even betting at -110 odds, you need to win 52.38% of your bets. Win less than that, and the vig slowly eats away at your bankroll.
Some markets have even higher juice, especially niche props or parlays. Always check the odds and know what you're paying.
Not all books have the same juice. Some sportsbooks have reduced juice, and are typically considered sharper books. Some may list a spread at -108 or -105 instead of -110. That small difference can compound over hundreds of bets. Shopping for the lowest juice is one of the simplest ways to increase your long-term ROI. We show you exactly how in the Line Shopping guide.
Bankroll Basics
We won't get too deep here, that's what the Bankroll Management guide is for, but know this: if you don't manage your bankroll, you won't last. Sports betting is about probability, and hot and cold streaks will happen. Set a unit size (typically 1% of your total roll), and don't chase losses. Consistency beats heat checks.
Live Betting, Parlays, and Props
You'll hear about these often:
- Live Betting: Odds shift in real-time. There's plenty of opportunities to take advantage of rapidly changing odds. We'll talk about how in later sections.
- Parlays: Multi-leg bets with huge payouts... but the juice stacks. Sportsbooks love them, and for a good reason. If you are looking to be a profitable bettor, you should typically avoid these. Curious what a parlay really pays versus what it should? Our parlay calculator will show you.
- Player Props: Bet on individual performances (e.g., LeBron Over 27.5 points). These markets are often very beatable with research and discipline. However, exploiting them can result in your betting account being limited fast. Our daily trend boards track graded prop results every day if you want to see how these markets actually behave.
We'll unpack all of this in future guides.
The Path Ahead
You've got the basics. Here's where to go next:
- Getting Started: choosing a book, funding an account, and placing your first bet
- Bankroll Management: unit sizing and the discipline that keeps you alive
- Line Shopping: why the price you pay matters as much as the side you pick
This is a long game. Betting 101 is just your first rep in the weight room.
Stay sharp.
