At its heart, a sports bet is a proposition: the sportsbook offers a price, you decide whether that price is worth taking, and money changes hands based on the result. The three building blocks below cover the overwhelming majority of wagers placed in the United States. Master these and everything else, from parlays to props, is just a variation.
The Three Core Bet Types
Moneyline: who wins
A moneyline bet is the simplest wager there is. You pick which team or player wins the game outright, with no margin of victory involved. Prices are shown in American odds. A negative number is the favorite and tells you how much you must stake to win $100; a positive number is the underdog and tells you how much you win on a $100 stake.
If the New York Yankees are -150 to beat a division rival, you risk $150 to win $100 (a $250 return). If the underdog is +130, a $100 bet wins you $130 (a $230 return). The favorite costs more because it is more likely to happen. The table below shows how a $100 stake pays out across a few common moneyline prices.
| Moneyline | Role | Stake | Profit if it wins | Total return |
|---|---|---|---|---|
| -200 | Favorite | $100 | $50 | $150 |
| -150 | Favorite | $100 | $66.67 | $166.67 |
| +130 | Underdog | $100 | $130 | $230 |
| +200 | Underdog | $100 | $200 | $300 |
Point spread: the margin
The point spread levels the field by handicapping the favorite. Instead of just picking a winner, you bet on the margin of victory. If the Buffalo Bills are -6.5, they must win by seven or more for your bet to cash. Take the underdog at +6.5 and you win if that team wins outright or loses by six or fewer. Because the half-point removes any chance of a tie, spreads with a .5 are common.
Most spread bets are priced at -110 on both sides. That extra 10 percent is the sportsbook's built-in margin, which we cover below.
Totals (over/under): the combined score
A totals bet ignores who wins entirely. The book posts a number for the combined points scored by both teams and you wager on whether the real total finishes over or under it. If a Knicks game has a total of 224.5 and the final score adds up to 230, the over cashes. Totals are a great entry point because you can enjoy a full game rather than sweating a single team.
Futures and parlays
Beyond single games, you will encounter futures (long-term bets like a team to win the championship, placed weeks or months in advance) and parlays (multiple bets combined into one ticket for a bigger payout, where every leg must win). Both are worth understanding, but as a beginner you should master single-game moneylines, spreads, and totals first. Parlays in particular look tempting because of their big potential returns, yet they carry a compounded house edge, as our parlay betting guide explains.
How Odds and the Vig Work
Every American price implies a break-even win probability. The formula for a favorite is risk divided by (risk plus 100), and for an underdog it is 100 divided by (100 plus the odds). A standard -110 line implies 110 / (110 + 100) = 52.38%. That means you must win more than 52.38% of your -110 bets just to break even.
Why not 50%? Because the sportsbook charges a fee called the vig (or juice). When both sides of a spread are -110, their implied probabilities add up to 52.38% + 52.38% = 104.76%. That extra 4.76% is the book's theoretical hold. Understanding this single fact is the difference between a casual bettor and a sharp one: you are not just trying to be right, you are trying to be right often enough to overcome the vig. Our odds explained guide goes deeper on converting between formats.
Placing Your First Bet
- Pick a market. Start with a single game and one bet type rather than a complicated multi-leg ticket.
- Check the price. Note whether you are getting -110, -150, or plus-money, and what that implies about probability.
- Set your stake. A common bankroll rule is to risk only 1% to 3% of your total on any single bet.
- Confirm and track it. Keep a simple record of every wager. Reviewing results is how you actually improve.
Where New Yorkers Can Bet
New York legalized regulated online sports betting in January 2022. Today there are nine state-licensed mobile operators, so residents have fully legal, in-state options to bet from their phones. Note that this legalization covers sports only; online casino and online poker remain illegal in New York as of 2026.
The offshore books we review, such as BetOnline and SportsBetting.ag, also accept New York players. These are unregulated operators based outside the US, and they compete on early lines, crypto banking, and props. We present both paths honestly so you can weigh the regulatory protection of a licensed book against the features of an offshore one. Compare your choices on our sportsbooks page.
Smart Habits From Day One
- Bet with a budget you can lose. Never chase losses with bigger bets.
- Shop lines. The same game can be -3 at one book and -3.5 at another; that half-point matters.
- Avoid betting your favorite team out of loyalty. Emotion is expensive.
- Understand the odds before the outcome. A good bet can lose and a bad bet can win.
One more habit worth building early: read the bet slip before you confirm. Check the stake, the odds, and the potential return the book displays. It sounds obvious, but a mistyped stake or an accidental tap on an alternate line is a common and avoidable way to lose money. Take the extra three seconds every time.
