Bet Types Explained

What does the spread mean in sports betting?

The spread is a handicap given to the underdog. If a team is -7.5, they must win by 8+ points for a spread bet to win. The underdog at +7.5 can lose by up to 7 and still cover.

How do betting odds work?

American odds show profit on a $100 bet. Positive odds (+150) mean $150 profit on $100. Negative odds (-200) mean you bet $200 to profit $100.

How do American sports betting odds work?

Positive odds (+150) show profit on a $100 bet — +150 means $150 profit. Negative odds (-200) show how much you must bet to win $100 — so $200 to win $100. The implied probability: for +150 it's 100/(100+150) = 40%; for -200 it's 200/(200+100) = 66.7%. The gap between true probability and implied probability is where the sportsbook makes its margin (the vig).

What is proper bankroll management for sports betting?

Never bet more than 1-5% of your total bankroll on a single wager. The Kelly Criterion is the mathematically optimal approach — it sizes bets based on your estimated edge. Most professionals use 1-2% per bet to survive variance. Track every bet in a spreadsheet. If your bankroll drops 50%, reduce bet sizes proportionally. The goal is survival, not one big win.

Are parlay bets a good strategy?

Parlays are the sportsbook's best friend — the house edge compounds with each leg. A 2-leg parlay has roughly 10% house edge; a 5-leg parlay can exceed 30%. Correlated parlays (where one outcome increases the likelihood of another) can offer value, but most recreational parlays are -EV. Stick to straight bets for consistent, long-term profitability.

Is live (in-play) betting profitable?

Live betting offers opportunities because odds update in real-time based on game flow, and sportsbooks can make mistakes pricing quickly changing situations. The edge: if you watch the game and understand momentum better than the algorithm. The risk: impulse betting and chasing losses increase dramatically with live betting. Use a pre-planned strategy, not gut reactions.

Where is sports betting legal in the US?

As of 2025, sports betting is legal in 38+ states and DC. Each state has its own rules about online vs. in-person betting, available sportsbooks, and bet types. Major operators (DraftKings, FanDuel, BetMGM, Caesars) are available in most legal states. Check your state's gambling commission website for the most current status and list of licensed operators.

Should I bet the point spread or moneyline?

Moneylines are simpler (pick the winner) but charge heavy juice on favorites. Point spreads level the playing field and typically offer -110 on both sides. For heavy favorites, the spread often offers better value than a -300 moneyline. For underdogs, moneylines let you win even if they lose by a few points. Many sharps use spreads because they provide more consistent -110 pricing.

What is the difference between a sharp and a square bettor?

Sharps are professional bettors who use data models, beat closing lines consistently, and profit long-term. Squares are recreational bettors who bet on favorites, parlays, and popular teams. Sportsbooks track this — sharp money moves lines, square money doesn't. Following line movements caused by sharp action (reverse line movement) is a common strategy for intermediate bettors.

Do I have to pay taxes on sports betting winnings?

Yes — all gambling winnings are taxable income in the US. Sportsbooks issue a W-2G for winnings of $600+ at 300:1 odds or more. Even without a W-2G, you're legally required to report all winnings. You can deduct gambling losses up to the amount of your winnings if you itemize deductions. Keep detailed records of every bet for tax purposes.

Can you make money betting player props?

Player prop markets are among the softest because sportsbooks price thousands of them daily with less modeling depth than main lines. Research-intensive bettors who track player usage rates, matchup data, and injury impacts can find edges. Same-game parlay props are especially soft — the correlation math favors informed bettors. Props are where most profitable recreational bettors focus.

What is a prop bet?

Proposition (prop) bets are wagers on specific events within a game, not the final outcome. Examples include "Will the quarterback throw for over 275.5 yards?" or "Which team scores first?" Player props focus on individual statistics; game props focus on in-game events. Props are especially popular for marquee games like the Super Bowl.

What is a futures bet?

A futures bet is a long-term wager on an outcome decided later — such as which team wins the Super Bowl or NBA Championship. Futures are placed before or during the season and can offer large payouts because of the uncertainty. The downside is your money is tied up for months and odds fluctuate as the season progresses.

Is sports betting legal in my state?

Sports betting is legal in over 30 U.S. states plus Washington D.C. States like New Jersey, Pennsylvania, Colorado, Michigan, and New York have robust legal markets. A handful of states like Utah and Hawaii prohibit all forms of gambling. Always check your specific state's current laws before wagering, as legislation changes frequently.

Which states do NOT allow sports betting?

As of 2026, states where sports betting remains fully illegal include Utah, Hawaii, Idaho, and Wisconsin. Several others allow limited forms but not full mobile betting. The landscape shifts regularly — states like Georgia and Minnesota have had active legislative efforts. Check a site like the American Gaming Association for current state-by-state status.

What can I do if sports betting is illegal in my state?

If sports betting is illegal where you live, your options are limited to legal ones: you can cross state lines to bet in a neighboring legal state, participate in legal fantasy sports (which is separate from sports betting in most jurisdictions), or wait for your state's laws to change. Never use offshore unlicensed sportsbooks — they carry serious legal and financial risks.

What does -110 mean on a bet?

-110 is the standard price for most point spread and totals bets. It means you must wager $110 to win $100 in profit. This built-in margin (called the "vig" or "juice") is how sportsbooks make money. Over time, paying -110 on both sides of a market is how books guarantee profit regardless of which team wins.

How do I convert between odds formats?

To convert American to decimal: positive odds → (odds/100) + 1; negative odds → (100/|odds|) + 1. To convert decimal to American: if decimal ≥ 2.0 → (decimal - 1) × 100 with a plus sign; if decimal < 2.0 → -100 / (decimal - 1). Most sportsbooks let you switch formats in your account settings, so manual conversion is rarely needed.

What is a moneyline bet?

A moneyline bet is simply picking which team or player wins the game outright — no point spread involved. Favorites have negative odds (e.g., -180) and underdogs have positive odds (e.g., +155). Moneyline bets are the simplest type of sports wager and great for beginners. Heavy favorites pay out little; underdogs pay more but win less often.

What is a point spread bet?

A point spread is a margin of victory set by oddsmakers to level the playing field. The favorite must win by more than the spread, while the underdog either wins outright or loses by less than the spread. For example, if the Chiefs are -6.5, they must win by 7+ for a spread bet on them to cash. Both sides typically pay -110.

What is a totals (over/under) bet?

A totals bet is a wager on whether the combined final score of both teams will be over or under a number set by the sportsbook. For example, if the total is 47.5, you bet whether the final combined score will be 48+ (over) or 47 or fewer (under). It does not matter who wins — only the combined scoring counts. Totals typically also pay at -110.

What is live betting (in-play betting)?

Live betting lets you place wagers on a game while it is in progress, with odds updating in real time based on the score and game flow. For example, you can bet on a team trailing at halftime at favorable odds. Live betting requires quick decisions, and sportsbooks briefly suspend markets after key plays. It adds excitement but also tempts impulsive wagering.

How does a parlay bet work?

A parlay combines two or more individual bets into one wager where all selections must win for you to collect. The payout is much larger than any single bet because the odds multiply together. A two-team parlay at -110 on each leg pays roughly +260. The risk: if even one leg loses, the entire parlay loses. Parlays are high-risk, high-reward by design.

Why are parlays considered bad bets?

Parlays are mathematically unfavorable because sportsbooks pay less than the true probability of all legs winning. A two-team parlay at -110/-110 should pay +300 at fair odds, but books pay around +260, pocketing the difference. The house edge compounds with each leg added. While parlays are fun for small stakes, serious bettors rarely rely on them.

DraftKings vs FanDuel — which is better?

DraftKings and FanDuel are the two largest U.S. sportsbooks, and both are excellent choices. DraftKings often has more same-game parlay options and a generous rewards program. FanDuel has a cleaner interface and often better NFL odds. The best approach is to have accounts at both so you can shop for the best lines and take advantage of each book's unique promotions.

How does BetMGM compare to Caesars Sportsbook?

BetMGM and Caesars are both strong mid-tier sportsbooks. Caesars is known for its generous welcome bonus and rewards program tied to Caesars Rewards hotel points. BetMGM offers strong same-game parlay features and broad market variety. Caesars historically offers better football lines; BetMGM is competitive for NBA. Having both accounts maximizes your line-shopping options.

What is bankroll management in sports betting?

Bankroll management means treating your betting funds as a dedicated budget and sizing each bet as a percentage of that total. Most professionals recommend risking 1–5% of your bankroll per bet. This ensures a losing streak will not bust you and allows you to bet consistently over a long sample size. Without it, even skilled bettors can go broke on short-term variance.

What is flat betting?

Flat betting means wagering the same dollar amount on every bet regardless of your confidence level. For example, always betting $25 per game. It is the simplest bankroll management strategy and protects against the common mistake of chasing losses by betting bigger after a bad run. Flat betting also makes results easy to track and analyze over time.

What is unit betting in sports?

Unit betting standardizes wager sizes so you can track performance across different bankroll sizes. One unit is typically 1% of your starting bankroll. If you have $500 and bet 1 unit, that is $5. Tipsters post results in units so followers with different bankrolls can replicate the same risk percentage. It makes performance tracking apples-to-apples across bettors.

Why should I track my bets?

Tracking every bet is essential for knowing whether you are actually profitable. Many bettors feel like they win more than they do — a detailed log reveals the truth. Tracking also identifies which sports, bet types, or situations you perform best and worst in, allowing you to focus on your genuine edges and cut losing habits before they drain your bankroll.

What is self-exclusion in sports betting?

Self-exclusion is a voluntary program where you ask a sportsbook or your state's gaming commission to block your access for a set period or permanently. Most U.S. sportsbooks and state authorities offer this tool. Once enrolled, you are removed from marketing lists and cannot create new accounts. It is an important option for anyone concerned about their gambling behavior.

How do I set betting limits on sportsbooks?

Most licensed U.S. sportsbooks offer responsible gambling tools in account settings: deposit limits, bet limits, loss limits, and session time limits. You can set daily, weekly, or monthly caps. Limits can generally be lowered immediately but take 24–72 hours to increase, preventing impulsive changes. Using these tools proactively is a hallmark of disciplined gambling.

How does NFL betting work for beginners?

NFL is the most bet sport in America. Beginners should start with moneylines (pick the winner), point spreads (win by a margin), and game totals (combined score over/under). Always shop for the best line across sportsbooks before placing a bet. The most important NFL tip: avoid betting on your favorite team, as emotional bias consistently leads to poor decision-making.

What are some NBA betting tips for beginners?

NBA games are high-scoring and fast-paced, making totals betting especially popular. Key tips: home teams outperform their spread more in the NBA than in other sports; back-to-back game fatigue on the second night often hurts performance; player props (points, rebounds, assists) can offer more value than game lines; and line movement during the day often signals sharp money.

What is a steam move in sports betting?

A steam move is a rapid, coordinated line movement caused by sharp bettors hitting the same side at multiple sportsbooks simultaneously. When you see odds shift suddenly across the market without any clear news, it often indicates professional money. Following steam moves is a strategy some bettors use, though the best prices are usually gone by the time casual bettors notice.

What is the difference between sharp and public money?

Sharp money comes from professional bettors who bet large amounts based on calculated edges. Public money comes from casual bettors who often back favorites, popular teams, and overs. Sportsbooks shade lines to account for sharp action. Reverse line movement — when a line moves opposite to where public bets are going — typically signals sharp money coming in on the other side.

What is vig or juice in sports betting?

The vig (vigorish) or juice is the sportsbook's built-in commission. On a standard -110/-110 market, the book keeps roughly 4.5% of every dollar wagered over time. To break even at -110, you need to win 52.4% of your bets. Books earn profit from the vig regardless of outcomes — which is why consistently winning long-term is genuinely difficult.

What is a two-way market in betting?

A two-way market offers only two outcomes — typically a moneyline with no draw option, common in American sports. Soccer uses three-way markets (Team A wins, Team B wins, or draw). American football, basketball, and baseball are two-way markets because ties are either impossible or decided in overtime. Two-way markets carry a lower implied vig than three-way markets.

What is a teaser bet?

A teaser is a modified parlay where you adjust point spreads or totals in your favor by a set number of points — typically 6 in football and 4 in basketball — in exchange for lower payouts. For example, a 6-point NFL teaser lets you move a -7 spread to -1 across multiple games. Teasers appear safer but the reduced payout often does not fully compensate for the points given.

What is a round robin bet?

A round robin generates a set of smaller parlays from a larger group of selections. Picking 4 teams and creating all possible 2-team parlays gives you 6 combinations. It provides partial coverage: if one team loses, you still win the parlays that did not include them. Round robins cost more than a single parlay but offer built-in protection against individual leg losses.

What is a pleaser bet?

A pleaser is the opposite of a teaser — you move the point spread against yourself in exchange for significantly higher odds. For example, moving an NFL spread 6 points in the wrong direction. Pleasers have very long odds and very low win rates and are considered high-risk novelty bets. Most casual bettors and many professionals avoid them entirely.

What does ATS mean in sports betting?

ATS stands for "against the spread." A team's ATS record shows how often they cover the point spread, separate from their straight win-loss record. A team might be 10-5 overall but 7-8 ATS if they consistently underperform relative to expectations. Bettors track ATS records to find teams or situations where the market is consistently mispriced.

What is a push in sports betting?

A push occurs when the final result lands exactly on the spread or total, resulting in a tie with no winner. Your original wager is refunded in full. For example, if the spread is -7 and the favorite wins by exactly 7, both bets push. This is why sportsbooks often set lines at half-points (e.g., -6.5) — to eliminate the possibility of a push.

What is a hook (half-point) in sports betting?

A "hook" is the half-point added to a spread to eliminate the possibility of a push. Lines like -3.5 or +7.5 are common. The key hook numbers in NFL betting are 3 (field goal) and 7 (touchdown), because games end on those margins most often. Buying the hook around these key numbers — paying extra to get -3 instead of -3.5 — is a common strategy discussion among experienced bettors.

Can I bet on sports from my phone?

Yes — all major U.S. licensed sportsbooks have iOS and Android apps. You must be physically located within a legal state's borders when placing a bet; apps use geolocation to verify this. You do not need to be a resident, just physically present. Make sure your VPN is turned off, as VPN use triggers geolocation failures and can get your account flagged.

What is the minimum age to bet on sports?

The minimum legal age to bet on sports is 21 in most U.S. states that have legalized it; a few states permit 18+. All licensed sportsbooks require age verification during account creation — typically a government-issued ID. Attempting to create an underage account is illegal and results in permanent account closure and potential forfeiture of any funds.

Do I have to pay taxes on sports betting winnings?

Yes — sports betting winnings are taxable income in the United States. Sportsbooks issue a W-2G form for winnings above $600 at odds of 300-1 or higher. Regardless of whether you receive a form, you must report all gambling winnings on your federal tax return. You may deduct gambling losses up to the amount of your winnings if you itemize deductions.

What is a bet slip?

A bet slip is the digital record of your wager showing the selection, odds, stake, and potential payout. On a sportsbook app, you add selections to your bet slip before confirming the bet. The slip shows exactly what you are risking and what you stand to win. Always review your slip carefully — mistakes cannot be reversed once a bet is confirmed and accepted.

What is arbitrage betting (arbing)?

Arbitrage betting involves placing bets on all outcomes of an event across different sportsbooks to guarantee a profit regardless of the result. It exploits pricing differences between books. For example, betting Team A at +110 on one book and Team B at +115 on another when the combined implied probability is under 100%. Arbers risk account restrictions from sportsbooks that detect the practice.

What does "action" mean in sports betting?

"Action" simply means a bet that is live and counts. If a game is postponed and your bet still stands, the book says your bet "has action" on the rescheduled game. It is also used informally to mean any betting activity. In baseball, "action" sometimes refers to a bet type where your wager stands even if the listed starting pitcher does not start.

What is a bad beat in sports betting?

A bad beat is when a bet you were winning loses at the last second due to an unlikely event — such as a backdoor cover where a team scores meaningless late points. For example, you hold a winning 3-point spread with seconds left, then the opponent scores a garbage-time touchdown to cover. Bad beats are a psychologically difficult but unavoidable part of sports betting.

What are key numbers in NFL betting?

Key numbers in NFL betting are the most common margins of victory: 3 (field goal), 7 (touchdown + extra point), 6, 10, and 14 are the most important. Lines at or near these numbers carry extra significance because games land on them frequently. Paying a small premium — like -120 instead of -110 — to get a spread of -2.5 instead of -3 is often worth it.

What is a middle in sports betting?

A middle is when you bet both sides of a game at different lines, hoping the final score falls between them so both bets win. For example, betting Team A -2.5 early and then Team B +4.5 after the line moves. If Team A wins by 3 or 4, both bets cash. If neither hits the middle, you typically lose only the vig — one bet wins, one loses.
