Spread, Moneyline, Total & Prop Bets

The market map

Spread: handicap the final margin

If a favorite is −3.5, it must win by at least four points for the favorite ticket to cash. If the underdog is +3.5, it can win outright or lose by three or fewer. The spread is a way to turn two different final scores into one yes-or-no margin question.

Half-points are important because they avoid a push on common numbers. When the line lands on a whole number, a final margin exactly equal to the line can create a push, depending on the market and house rules. Alternate spreads change both the handicap and the price; do not compare them as if only the number changed.

Moneyline: remove the handicap

A moneyline bet only asks who wins. The favorite usually costs more to back, while the underdog offers more profit if it wins. That makes the moneyline useful when you believe a team’s win probability is higher than the price implies, but it is not automatically “safer” than a spread. You can be right about the stronger team and still pay too much for the certainty.

Total: forecast the combined score

An over/under depends on both offenses, both defenses, game pace, early-down success, fourth-down decisions, field position, red-zone outcomes, weather, and late-game incentives. An under is not simply “bet the bad offenses,” and an over is not simply “bet the fast teams.” The number already contains the market’s prior beliefs.

Props: isolate one event, inherit more rules

Player props can be passing yards, receptions, rushing attempts, sacks, touchdowns, or combinations. They look precise, but the precision can be cosmetic. The line may depend on a player’s role, snap share, route participation, injury status, game script, and whether the operator voids the bet after a late scratch.

Before playing one, record the exact player, line, price, statistical definition, and settlement rule. Our player-prop guide explains the process in more detail.

Convert the price before you compare markets

The same American price can appear across a spread, total, or prop, but the underlying event is different. Convert the price first, then compare the event definition. Do not treat a −110 spread and a −110 player prop as the same kind of risk.

Small details that change settlement

• Check whether a game must be completed for action and what happens after a postponement.
• Check whether a player must take a snap, record a statistic, or meet a minimum for a prop to be live.
• Check whether overtime counts for the market you chose.
• Check whether alternate lines and same-game combinations have different rules.
• Save the terms at the moment you place the bet, because promotional and market wording can change.
