How to Evaluate and Select a Sportsbook

It’s essential to find a set of sportsbooks that fit your needs well, will keep you engaged, and provide the best odds and offers for your sports betting activity. We leveraged insights from our internal team and scraped and sourced external user review data to complete a robust analysis of each sportsbook to help your selection process.

Evaluation Criteria

Here are the factors considered, tested and weighted in our online sportsbook reviews:

Bonuses & Promotions

We took a look at sign-up offers, ongoing promotions, and the loyalty programs available from each sportsbook in legal states (e.g., Michigan or Arizona). Every book has its unique strengths: particularly compelling sign-up offers for new bettors, diverse markets and bet types, or lucrative VIP programs. We joined each book as a new user and pooled input from our team of passionate sports bettors with in-depth book experience to highlight where you can get the most from Bonuses & Promotions.

Mobile App

We downloaded available mobile apps for each sportsbook, completed their onboarding, and explored the app layout on mobile and mobile web. We noted any bugs or glitches experienced and compared ease-of-betting experience across books. Additionally, we performed an analysis of trends in user review data from the Apple App Store and Google Play. Trends from this research have been highlighted in our review to represent a broader audience of sports bettors and bring national user data and insight into our analysis.

Registering & Cashiering

It’s imperative to be able to trust a sportsbook with your money, and the experience of cashing in and out is a critical factor in selecting a sportsbook. The best books give various cashiering options, including credit and debit cards, PayPal, online banking, checks, and/or wire transfers. Additionally, bettors want these transactions to be fast and supported by responsive customer service. We tested each flow and available payment methods. We consider being able to cash out in under two days reasonable.

Betting Options

We looked into the types of bets offered (e.g., spreads, moneylines, totals) and available sports (e.g., NFL, CFB, NASCAR). Some books have more extensive sports availability and distinct bet types. Depending on your interests and preferences, there may be a collection of sportsbooks that help achieve your optimal sports betting experience, rather than just one.

Competitor Comparison

We lined up each sportsbook head to head vs. direct competitors, highlighting strengths and weaknesses. Some sportsbooks may excel in certain areas, like new betting markets, while struggling with user experience. In our reviews, you’ll see how the books line up.

Betting Resources & Information

Examples of Legal Bet Types

Here are some examples of the bet types sports fans can wager on:

  • Point Spreads. Spread betting is a bet on the margin of victory in a game, or the point "differential." (See: Our Guide to Point Spread Betting)
  • Moneylines. Moneyline betting is when you pick the winner of the game or event, either one team or another. (More detail here: Moneylines)
  • First Half & Second Half. Halves let a bettor treat the first half and the second half as separate matches. (Additional insights: Half Bets)
  • Totals. A total, also known as an over/under, is a bet on the number of points both teams will combine to score in a game. (See: Understanding Totals in Sports Betting)
  • Futures. Future bets are a bet on an event that will be decided in the future (e.g., end-of-season results). (More: Longer-term Betting: Futures)
  • Player Props. A "prop" bet, short for a proposition, is a wager that is not directly tied to the final score or outcome. (See: Everything to Know About Prop Bets
