Bet Types Explained

From a simple moneyline to a multi-leg parlay, every bet type has its own structure, risk profile, and strategic use case. Learn how each one works before you place it.

Most sportsbooks offer dozens of betting markets on every game. But the vast majority of bets fall into a handful of core types. Understanding the mechanics of each — and when to use them — is the foundation of any betting strategy.

Moneyline

Core Bet

Pick a winner. No spread, no conditions — just which team wins the game outright.

How it works

The moneyline is the simplest bet in sports betting. You choose which team wins, and the odds reflect how likely that outcome is. Favourites carry negative odds (you risk more to win less); underdogs carry positive odds (you risk less to win more).

The gap between the favourite's and underdog's odds is where the sportsbook's vig lives. The wider the gap, the more juice you're paying.

Example— Kansas City Chiefs vs. Buffalo Bills

Kansas City Chiefs	-165	Bet $165 to win $100
Buffalo Bills	+140	Bet $100 to win $140

If you bet $100 on the Bills at +140 and they win, you collect $240 total ($140 profit). If you back the Chiefs at -165, you need to wager $165 to profit $100.

Best for

Games where you have a strong opinion on the winner but the spread feels too wide
Underdog hunting — a few +150 wins can offset several losses

Watch out for

Heavy favourites at -200 or worse require a very high win rate just to break even
Parlaying moneylines amplifies both the payout and the house edge

Point Spread

Core Bet

Bet on the margin of victory, not just the winner. The favourite must win by more than the spread; the underdog must lose by less.

How it works

The point spread levels the playing field between mismatched teams. The sportsbook sets a number — say, -6.5 — that the favourite must win by for spread bettors to collect. The underdog can lose the game outright and still cover, as long as they lose by fewer than 6.5 points.

Most spread bets are priced at -110 on both sides, meaning you pay roughly the same juice regardless of which team you back. The spread itself is the handicap, not the odds.

Example— Los Angeles Rams -6.5 (-110) vs. Seattle Seahawks +6.5 (-110)

Rams -6.5	-110	Rams must win by 7 or more
Seahawks +6.5	-110	Seahawks must lose by 6 or fewer, or win

If the Rams win 24–17 (a 7-point margin), Rams -6.5 bettors win. If the Rams win 24–20 (a 4-point margin), Seahawks +6.5 bettors win — even though Seattle lost the game.

Best for

Games between evenly matched teams where the moneyline offers little value
Situations where you expect a blowout or a close game regardless of the winner

Watch out for

Key numbers — spreads of -3 and -7 in football carry extra significance and are priced accordingly
Late-game garbage time scoring can swing a cover without affecting the game's outcome

Over/Under (Total)

Core Bet

Bet on the combined score of both teams — whether it will be over or under the sportsbook's posted number.

How it works

The total is the sportsbook's projection of how many combined points both teams will score. You bet whether the actual total will be higher (over) or lower (under) than that number. You are not picking a winner — only the scoring volume.

Totals are typically priced at -110 on both sides, just like spreads. If the final score lands exactly on the total, the bet pushes and your stake is returned.

Example— Golden State Warriors vs. Boston Celtics — Total: 224.5

Over 224.5	-110	Combined score must be 225 or more
Under 224.5	-110	Combined score must be 224 or fewer

If the final score is Warriors 118, Celtics 109 — the combined total is 227. Over bettors win. If the game ends 112–108 (total: 220), under bettors win.

Best for

Games where you have a strong read on pace, defence, or weather but no clear winner
Situations where both teams are evenly matched and the spread feels like a coin flip

Watch out for

Late-game intentional fouling or garbage time can push a total over in the final minutes
Injury news and lineup changes can shift totals significantly — always check before betting

Parlay

Multi-Bet

Combine two or more bets into one wager. Every leg must win. The payout grows with each leg — and so does the risk.

How it works

A parlay links multiple individual bets into a single wager. The winnings from each leg roll into the next, creating a compounding payout. A two-team parlay at -110/-110 pays roughly +260; a three-teamer pays around +600.

The catch: if any single leg loses, the entire parlay loses. Sportsbooks love parlays because the true odds of hitting all legs are always worse than the payout offered — the house edge compounds with every added leg.

Example — 3-leg parlay— Three -110 bets combined into one parlay

Chiefs -3.5	-110	Leg 1
Over 47.5	-110	Leg 2
Lakers ML	-110	Leg 3

A $100 three-team parlay at -110/-110/-110 pays approximately $596 if all three legs win. But the true probability of hitting all three at 52.4% each is only about 14.4% — the payout implies a 14.3% chance, so the edge is razor-thin and the variance is enormous.

Best for

Correlated parlays — where one outcome makes another more likely (e.g., a team wins big AND the total goes over)
Small-stake entertainment with outsized upside — treating it as a lottery ticket, not a strategy

Watch out for

The house edge compounds with every leg — a 5-team parlay can carry a 30%+ effective vig
Sportsbooks cap correlated parlays precisely because they offer the bettor a genuine edge

Teaser

Multi-Bet

A modified parlay where you move the spread or total in your favour by a set number of points — in exchange for a reduced payout.

How it works

A teaser lets you adjust the point spread or total on two or more games by a fixed number of points — typically 6, 6.5, or 7 in football. You're buying a better number, but the payout is lower than a standard parlay.

The strategic value of teasers comes from crossing key numbers. A 6-point teaser that moves a -7 favourite to -1, or a total from 47.5 to 41.5, crosses the critical 3 and 7 thresholds in football — dramatically improving your probability of covering.

Example — 6-point football teaser— Two NFL games, 6-point teaser

Chiefs -7 → -1		Moved 6 points in your favour
Bills +1 → +7		Moved 6 points in your favour

A standard two-team 6-point teaser pays around -120. You're giving up payout in exchange for a much more favourable number. The Chiefs now only need to win by 2 instead of 8; the Bills can lose by up to 7 and still cover.

Best for

NFL teasers through key numbers (3 and 7) — this is where teasers offer genuine mathematical value
Reducing variance on games you feel strongly about without giving up the multi-game structure

Watch out for

Basketball teasers rarely offer value — scores are too high and key numbers are less meaningful
Adding more than two legs to a teaser erodes the value quickly

Prop Bets

Proposition

Bet on specific events within a game — player statistics, individual performances, or game occurrences — rather than the final score.

How it works

Proposition bets (props) are wagers on outcomes that don't directly affect the final score. Player props focus on individual statistics — passing yards, points scored, strikeouts thrown. Game props cover broader events — will there be overtime, which team scores first, total team sacks.

Props are often less efficiently priced than spreads and totals because sportsbooks devote less resources to setting them. Sharp bettors frequently find more value in props than in main markets — but the limits are also much lower.

Example — Player prop— Patrick Mahomes Passing Yards

Over 284.5 passing yards	-115	Mahomes throws for 285+ yards
Under 284.5 passing yards	-105	Mahomes throws for 284 or fewer yards

If Mahomes finishes with 291 passing yards, the over wins. Props like this are set based on season averages and matchup data — but they're also influenced by public perception of star players, which can create value on the under.

Best for

Bettors with deep knowledge of specific players or matchups that the market undervalues
Finding soft lines — prop markets are less efficient and move more slowly than main markets

Watch out for

Lower betting limits — sportsbooks restrict prop bet sizes precisely because they know the lines are softer
Late scratches and lineup changes can invalidate your entire read on a prop

Futures

Season-Long

Bet on outcomes decided weeks or months from now — championship winners, award recipients, or season win totals.

How it works

Futures are long-term bets on outcomes that won't be settled until the end of a season, tournament, or award cycle. Common futures include Super Bowl winner, NBA MVP, World Series champion, and team season win totals.

Futures carry a high house edge — the implied probabilities of all outcomes typically sum to 130–150%, meaning the book keeps 30–50 cents of every dollar wagered. The appeal is the potential for large payouts on underdog picks made early in the season.

Example — NFL Super Bowl futures— Super Bowl winner odds (pre-season)

Kansas City Chiefs	+600	Bet $100 to win $600
Philadelphia Eagles	+800	Bet $100 to win $800
Field (all others)	+200	Any other team wins

A $100 bet on the Chiefs at +600 returns $700 if they win the Super Bowl. The value in futures comes from identifying teams the market underestimates early — before injuries, trades, and results sharpen the line.

Best for

Pre-season or early-season bets on teams you believe are undervalued by the market
Win totals — often more efficiently priced and easier to research than outright championship bets

Watch out for

Your money is tied up for the entire season — opportunity cost is real
The house edge on futures is among the highest of any bet type — shop multiple books aggressively

Choosing the Right Bet Type

No single bet type is universally better than another. The right choice depends on your edge — where your knowledge or research gives you an advantage over the market. Moneylines and spreads are the most liquid and efficiently priced. Props and futures offer softer lines but come with lower limits and higher variance.

The most important rule: understand exactly what you're betting on before you place it. Every bet type has a specific win condition, and confusing a spread bet for a moneyline — or misreading a total — is an avoidable mistake.
