Moneyline – The Straight‑Up Scorecard
Look: the moneyline is the simplest way to bet on who wins. A minus sign means the favorite; the larger the number, the deeper the pocket you must dig. A plus sign signals the underdog; the bigger the figure, the fatter the payoff. Example: -150 means you risk $150 to win $100, while +130 means a $100 stake yields $130 profit if that team pulls off the upset.
Point Spread – The Balance Beam
Here’s the deal: sportsbooks add a virtual handicap to level the playing field. If the Patriots are -7.5, they must win by eight or more for a spread bet to cash. Conversely, the Dolphins at +7.5 win outright or lose by seven or fewer points. The spread is the most popular line because it forces you to think beyond just the winner.
Why the Half‑Point Matters
And here is why. A half‑point (the “hook”) ensures there are no ties—no push, no refunds. It forces a decisive outcome, which keeps the vig humming.
Total (Over/Under) – The Game’s Scorecard
Betting the total is all about predicting the combined points. The line might sit at 48.5. If you take the over, you’re betting the teams will combine for 49 or more points. The under means you expect 48 or fewer. You’re not picking a winner, just the tempo of the clash.
Prop Bets – The Side‑Show
Prop bets let you wager on anything from “first touchdown scorer” to “number of sacks.” They’re the playground for those who love stats, and they often carry higher odds because the outcomes are more volatile.
Odds Formats – Speak the Language
American odds dominate US sportsbooks, but you’ll also see decimal (e.g., 2.50) and fractional (5/2) formats overseas. Convert them and you’ll see the same implied probability lurking beneath. American to decimal: (odds > 0) → (odds/100)+1; (odds < 0) → (100/|odds|)+1. Fractional to decimal is just the fraction plus one.
Implied Probability – The Hidden Metric
Every line hides a percentage. A -150 favorite translates to a 60% implied win chance (100/(150+100)). A +130 underdog shows about a 43% chance (100/(130+100)). Compare these percentages to your own assessment; that gap is where value lives.
Juice (Vig) – The House Cut
Look: sportsbooks take a commission—usually 10% of the pot. In a -110 line, you risk $110 to win $100. That extra $10 is the vig. If you find a -105 line on the same game, you’ve shaved $5 off the commission, boosting your long‑term ROI.
Line Movement – The Market Pulse
Sharp money, injuries, weather—any of these can shift the line. A sudden move toward the favorite often means big‑betters are backing that side. Follow the money, not the hype. If the spread slides from -7.5 to -6.5, the market is betting the favorite will not dominate as far as originally thought.
