Sportsbooks Use Human Nature to Increase Profits


Human nature makes some bets more likely than others. Sports fans like to “ride the coattails” of perennial winners. The same holds true for bettors. These biases increase the profit margin for sportsbooks. Here are some examples of how sportsbooks use human nature to increase profits. It is easy to see how biases can help sportsbooks make more money. Read on to learn how biases affect your betting decisions.

Sharp money

There are a variety of routes to becoming a sharp money bettor at a sportsbook. A sharp is a bettor who follows the money and profits when the bet is executed properly. A sharp is a highly skilled gambler who has made more money at a sportsbook than the “square” bettor. In fact, sharps are so successful that land-based sportsbooks even keep records of their wagers.


In the world of sports betting, the term “square sportsbook” is used to describe the opposite of sharp line sportsbooks. Square bettors tend to be novice or casual bettors who place wagers on parlays, prop bets, or other bets that are not the most profitable options. A square sportsbook will not move its lines until a sharp line sportsbook moves theirs. Hence, a square sportsbook primarily caters to the public “square” bettors.


In a steam sportsbook, you can bet on a game with a line that moves based on many different factors. While most moves are caused by natural factors, others are the result of square action in reaction to widely reported events. These factors include injury reports, low morale, or a big win or loss. These factors cause the book to change the number to keep bets evenly split. While this method is not a good choice for every player, it can sometimes produce winning bets.

Straight Up

A Straight Up sportsbook is a book that provides bettors with free picks for virtually every matchup. These picks are based on the straight up line, meaning the winner of a game will win regardless of the point spread. In the case of a football game, the Giants won 20-18, but failed to cover the spread. For basketball games, a Straight Up sportsbook can offer free picks on nearly every matchup.

Circle Game

The first thing to know about the Circle Game sportsbook is what it is. It is basically a section on the sportsbook’s website where you can bet on games based on their opening odds. This section is usually empty, but in some cases it is filled with games. These games may be available in various betting limits. However, they are not offered as props. In addition, the points spread and totals may be changed before the game begins.

Opening Line

The Opening Line of a sportsbook is the consensus line for that particular game. These lines are rarely exactly the same as the closing line. However, as more bets are placed, the lines become more solidified. Therefore, it is helpful to watch the movement of the opening line. It will give you a clear idea of betting trends. Here are some things to keep in mind when looking at the Opening Line of a sportsbook.

Closing Line

The Sportsbook Closes Line is an important tool for any savvy bettor. It’s the number that’s closest to the final closing price, and as the line moves closer to that number, the limits of your bet increase. These limits reflect implied probabilities of the final outcome, such as a 50-50 chance of a team winning or losing. If you can consistently get line value, you will have an edge in betting.


When you place your bets on sports games, you need to know how point-spreads work. This is a number set by the sportsbook on the outcome of the game and is intended to encourage equal betting action between the two teams. The favorite is assigned a negative number, meaning they have to beat the point-spread team by a certain number of points. This gives the underdog a good chance of winning the spread bet.

Moneyline odds

If you are planning to bet on several different sports at a sportsbook, you must pay attention to the moneyline odds at each of them. These odds can vary widely, which can make it difficult to choose the best bet. You may need to spread your bets across different sportsbooks in order to get the best payouts. To make sure you’re choosing the best moneyline odds for your bets, keep the following tips in mind.

Proposition bets

If you enjoy betting on sports, you may want to try your hand at sportsbook proposition bets. These bets are softer than standard wagers, and they’re great for sports enthusiasts who are passionate about handicapping. They can be placed on anything from the performance of a quarterback to the game’s final score. You can place these bets at offshore sportsbooks or domestic sportsbooks, and they are generally worth a shot. However, they can also be confusing, so it’s important to understand their payout structures and limitations before placing a wager.
