Odds
Odds are the foundation of every sports bet. They represent both the likelihood of an outcome and the potential payout if your bet wins.
How It Works:
Let’s say the odds are -150 on the favorite and +130 on the underdog:
- A -150 means you’d need to bet $150 to win $100.
- A +130 means a $100 bet wins $130.
These odds tell you not just how much you’ll win, but also who the bookmakers expect to win.
Strategic Tip:
Look for value bets, which are spots where your prediction has a higher chance of hitting than the implied odds suggest. Smart bettors compare odds across sportsbooks to find the best edge.

Favorites & Underdogs
In nearly every sports matchup, oddsmakers assign one team as the favorite and the other as the underdog.
- Favorites are expected to win and come with lower odds and lower payouts.
- Underdogs are less likely to win but offer higher potential payouts.
How It Works:
If the Kansas City Chiefs are listed at -180 and the Las Vegas Raiders are +150, that means the Chiefs are the favorite. You’d need to bet $180 to win $100 on the Chiefs, but a $100 bet on the Raiders would win you $150 if they pull off the upset.
Strategic Tip:
Underdogs offer value if you believe the public is overhyping the favorite. Sharper bettors know how to spot these opportunities and capitalize.

Moneyline Bets
Moneyline betting is the simplest and most popular way to wager — you're just picking the winner.
- Negative odds (e.g. -200) indicate a favorite.
- Positive odds (e.g. +175) represent the underdog.
- Most popular in baseball and hockey.
Sports Betting Example:
Betting $100 on an underdog listed at +175 pays out $175 if they win. Betting $200 on a favorite at -200 wins $100.
Strategic Tip:
Use moneyline betting for small underdogs with a strong chance of pulling off a win, or when you have confidence in an even matchup.

Spread Bets
Also known as point spread betting, this type evens the playing field between two teams by assigning a handicap.
- The favorite must win by more than the spread to cover.
- The underdog must lose by less than the spread or win outright.
- Most popular in football and basketball.
Sports Betting Example:
If the 49ers are -6.5 vs. the Seahawks, the 49ers must win by 7+ for your bet to win. If they win by 6 or fewer (or lose), you lose your bet.
Strategic Tip:
Study team trends like blowouts, garbage-time scoring, and key injuries that can influence a team’s ability to cover.

Over/Under (Totals) Bets
In Over/Under betting, you bet whether the total combined score of a game will go over or under a set number.
- Great for games with explosive or sluggish offenses.
- Most popular in football and basketball.
Sports Betting Example:
If the total is set at 48.5 for a Chiefs vs. Bills game and the final score is 30-24 (total 54), the "Over" wins.
Strategic Tip:
Study team scoring averages, weather forecasts, and injury reports to make smarter O/U bets.

Parlay Bets
Parlays allow you to combine multiple bets into a single wager for bigger payouts.
- All legs must win for the parlay to cash.
- Riskier than single bets but can offer exponential returns.
Sports Betting Example:
Betting $25 on a 3-leg parlay of:
- Cowboys -3.5
- Lakers moneyline
- Over 44.5 in Jets vs. Bills
If all three win, you could earn over $150.
Strategic Tip:
Only parlay bets that have true individual value. Don’t chase high payouts just to gamble — think of parlays as bonus bets with calculated risk.

Same-Game Parlays
Same-game parlays (SGPs), or Bet Builders, are custom parlay bets built around a single event.
- Combine spreads, totals, player props, and more.
- Ideal for high-profile games with tons of betting markets.
Sports Betting Example:
In a single 76ers vs. Heat game:
- Joel Embiid Over 25.5 pts
- Total Over 218.5
- Heat +4.5
If all three legs hit, you win your SGP.
Strategic Tip:
Study the matchup from multiple angles: defensive matchups, pace of play, and injuries. SGPs reward well-researched angles.
