Level 1 · The Basics

Moneyline, spread and over/under

Lesson 1 of 7 · 3 min read

Almost every game on the board offers the same three bets. Each one asks a different question about the same game, so one team can win you one bet and lose you another. Here is what each bet asks and how it gets graded.

Moneyline: who wins?

A moneyline bet is the simplest: you pick the team that wins the game, whatever the score. The catch is the price. The favorite, the team expected to win, carries minus odds like −180, so you risk more than you can win. The underdog carries plus odds like +155, so you can win more than you risk. The next lesson shows you how to read those numbers.

Spread: by how much?

A spread bet evens out a lopsided game by handicapping the favorite. Bears −3.5 means the Bears must win by 4 or more for a Bears bet to win. Lions +3.5 means a Lions bet wins if the Lions lose by 3 or fewer, or win outright. Winning a spread bet is called a cover. Both sides are usually priced near −110, but the price still matters as much as the number.

The number a bet is graded against, like −3.5 here, is called the line. When the line is a whole number, like −3, the game can land exactly on it. That is a push: nobody wins and your stake comes back. A half-point, called the hook, rules a push out.

Over/under: how many points?

An over/under bet ignores who wins. The book sets a number for the two teams' combined score, and you bet whether the real score lands over or under it. Over 44.5 wins at 45 or more combined points; under 44.5 wins at 44 or fewer. You can be right without caring who wins.

The baseball and hockey versions

Because the number barely changes from game to game, the price does the work instead. So many baseball and hockey games end by a single run or goal that a favorite at −1.5 is often priced at plus money.

One game, three answers

These bets are separate. A team can win the game, fail to cover, and play in a game that goes under, all on the same night. When a price on Consensus Edge looks strange, first check which of the three questions it answers.

Example. Bears vs Lions, with illustrative prices (not live data):

BetBearsLions
Moneyline−180+155
Spread−3.5 (−110)+3.5 (−110)
Over/under 44.5Over −110Under −110

Final score: Bears 24, Lions 20.

  • Moneyline: the Bears won, so Bears −180 wins and Lions +155 loses.
  • Spread: the Bears won by 4, more than 3.5, so Bears −3.5 covers.
  • Over/under: 24 + 20 = 44 points, below 44.5, so the under wins.

Make it Bears 23, Lions 20 and the Bears still win the moneyline, but Lions +3.5 covers. Had the spread been exactly −3, that 3-point win would be a push.

Key takeaway. The moneyline asks who wins, the spread asks by how much, and the over/under asks how many points both teams score together, so check which question a price answers before you bet it.
