How to Make Money at a Sportsbook


Traditional online sportsbooks operate on flat fees that customers must pay regardless of the number of bets they place. This model doesn’t scale well, since customers will pay the same amount during off-season games as they will during big events. In addition, customers won’t be able to adjust their bet size to reflect market fluctuations. In addition, traditional online sportsbooks don’t offer a way for customers to place more bets without incurring additional costs.

Arbitrage is a risk-free way to guarantee a profit

To make money at a sportsbook, you have to know how to make the best use of odds. While betting on the moneyline or spread can reduce your risk, the downside is that you might not get the same amount of upside as you would with an odds boost. But with the right knowledge and a little luck, you can make a killing arbitraging.


When you bet on sports, you must be aware of the margin at sportsbook. The margin at sportsbook equals Probability 1 + Probability 2 and can be calculated in a variety of ways. For example, in the recent tennis final between Novak Djokovic and Juan Martin Del Potro, the odds were 1.45 for Djokovic to win and 2.84 for Del Potro to win. The sportsbook’s margin in this scenario was 4%.

Alternate lines

Alternate lines in sportsbooks allow you to bet on a variety of games with varying odds. They’re a copycat of standard betting lines, but with a few twists. In NBA basketball, for example, you can bet on a wide range of NBA props. If you like parlays, you can bet on NBA props and get great odds on the underdogs.

Middle/Middle bets

While betting on the middle seems like an easy win, you should remember that the line numbers on a given game never remain static, and you can win or lose by betting on the middle. That’s because the odds are higher for the opposite team than the opposite side. In addition, the line numbers can change after you’ve placed your bet. You’ll only break even if you hit the middle one time out of twenty.

Cash-out option

Before you place a bet, check the sportsbook’s terms and conditions and house rules to determine if they allow you to cash out early. Cash-out options vary greatly between sportsbooks. Some follow industry standard practices, while others have site-specific rules. The sportsbook will determine whether you can cash out early based on several factors, including the correct current value of your wager. In some cases, cash-outs will be processed as soon as you hit a certain limit.

Site credit

A site credit for sportsbook is similar to a free bet, but instead of using it all at once, you can split it into multiple wagers. For example, if you’ve got $30 in site credit, you could place two $15 bets and three $10 bets, depending on how much you want to risk. A risk-free bet is a special type of bet that gives you something back if you lose, typically up to the amount of your bet.
