ESPN BET Quick Facts

All new bettors must register for a new account to place bets and claim welcome bonuses. Fortunately, most sportsbooks streamline the process into a few simple steps.

While these steps can vary by operator, the general principles are the same no matter who you go with. Here's a quick step-by-step process on how to get started:

1. Pick a top betting site and click the BET NOW button to start registration and activate any promo code. Be sure to enter the promo code during sign-up—it can't be added later.
2. Enter details like name, email, address, and phone number. Some operators may also require a username and password.
3. Confirm you're at least 21 years old and located in a state where the sportsbook is live.
4. Make the required minimum deposit (usually $20 or less) to fund your account and unlock the welcome bonus.

Different players will want different features out of their betting site. Below we've listed the specific features that we use to rank the best betting sites for sports. Read through them and then determine which ones matter most to you before deciding which sports betting sites are best for you.

Generous Sportsbook Promos

The welcome bonus offer you receive upon signing up with the appropriate promo code is your first impression of a sports betting site. Beyond that, it's important to find an operator that also delivers recurring promotions that increase your potential profit, provides insurance on select wagers, and offers contests to differentiate your online sports betting experience.

Top Features

We value legal sports betting sites and online sportsbooks that go above and beyond to create an outstanding experience for sports bettors. Key features we prioritize include a user-friendly mobile app, competitive odds, diverse betting markets, live betting options, early cash-out, streaming capabilities, casino and poker integration, and robust responsible betting tools.

Banking Methods And Payout Options

Each online sports betting site involves wagering real money to place your bets. That means it's important to find operators that provide players with a number of different payment method options when making deposits. It's also good to find operators that have multiple options for withdrawing funds. The good news is the legal and licensed operators in this article do just that, giving all types of players an option to do their banking with popular methods.

Competitive Betting Odds & Lines

Most NFL betting sites will have similar odds, but even small differences can make a difference in the long run. Odds of -110 and -120 may not seem like a big deal, but over the course of 10, 50, or 100 wagers, it adds up. It's also why we recommend signing up with multiple online sportsbooks so you can shop odds before ultimately placing your wagers. Odds of +180 and +200 mean a $100 wager pays out $180 in profit rather than $200.

Safety And Security

Playing at sports betting sites requires bettors to enter their personal and banking information. That makes it imperative that operators have secure operations, encrypted data, and top-level security to ensure the safety of that data. It's also important that bettors have ample resources to help them bet responsibly, which many offer in the form of links to safe gaming, FAQ sections, and customer support staff that is available 24/7.

Players can choose from about a dozen different bet types at their preferred betting site. Here's a quick rundown of the various wagers you can place across available betting markets. Use our betting odds calculator to determine the potential payout for each bet

• Moneyline: Moneyline bets involve wagering on the outcome of an individual game or event.
• Point Spread: A point spread represents the expected point difference and margin of victory between two teams.
• Over/Under Total: The over/under total is a way for users to wager on a projected total, either betting on the final number to be lower or higher than what the sportsbook lists.
• Parlay: A parlay involves making two or more bets at once and combining them into one wager, often resulting in a larger potential payout.
• Same-Game Parlay: A same-game parlay is any parlay that is made using wagers exclusively from one game.
• Player Prop Bets: A player prop bet (or propositional bet) is when you wager on a player achieving or not achieving a specific outcome, like scoring a touchdown or hitting a home run.
• Game Prop Bets: A game prop bet involves wagering on a specific game outcome that is independent of the result of the matchup.
• Teasers: Teaser bets allow the wagerer to slightly adjust total or over/under points in their favor.
• Futures: Futures bets represent wagers that can be placed on future events or outcomes, like who will win the Super Bowl or who will win league MVP.
• Boosts: Boosts, often awarded as tokens, give sportsbook users more favorable odds or increased profit potential for a specific wager.

Live Betting

Players will have the ability to make wagers at the best sportsbooks while games are happening. Live betting has increased in popularity in recent years, likely because of the abundance of options to watch live games. Sports betting sites will offer live odds such as moneylines, spreads, totals, and props that constantly fluctuate based on the status of the game and the time remaining. That's why it's important to find a betting site with fast response times and refresh rates so you can complete live betting wagers.

No matter the sport, top online sportsbooks offer hundreds of betting options year-round. Use tools like RotoWire's betting odds calculator to maximize your profits.

To help you find the right platform, we've curated a list of the top recommended online betting sites for some of the most popular sports in the US.

Sports betting sites require players to deposit funds into their accounts to place wagers. That makes it important for those online sportsbooks to have many different banking options like online bank transfers and PayPal to make deposits and withdrawals. 

These options vary by operator, but generally, players can expect to see these banking options when they sign up. Note that an online sportsbook will not charge fees for any payment methods, but the banking option you use might if you use, for example, a credit card to deposit funds.

Deposit Methods

Withdrawal Methods

Here's a quick list of all the states currently offering online sports betting, along with their respective launch dates.

Potential State Launch News

Currently, there are no states scheduled to launch online sportsbooks in 2024. The earliest we are expecting a new state to legalize online sports betting is 2025.

The best US sports betting sites place a strong emphasis on responsible gambling, offering a variety of tools and resources to support users who may struggle with problem gambling. These sportsbooks provide options for setting deposit, wagering, and time limits to help players manage their betting habits and maintain control over their gaming experience. These features are designed to keep betting fun, safe, and within personal financial limits.

Tools for Responsible Gambling

Most online sportsbooks allow users to:

• Set Deposit Limits: Control the amount you can deposit in a specific time frame.
• Wagering Limits: Restrict the amount you can bet in a single day, week, or month.
• Time Limits: Monitor and limit the amount of time you spend on the platform.
• Self-Exclusion: Temporarily or permanently block yourself from using the platform if necessary.

These measures are in place to ensure that gambling remains an enjoyable form of entertainment and does not become a financial or emotional burden.

Responsible Gambling Support

Responsible gambling means recognizing when betting is no longer fun and taking steps to regain control. The National Council on Problem Gambling (NCPG) offers confidential, 24/7 support through multiple channels:

• Phone: Call the helpline at 1-800-522-4700.
• Text: Send a message to the same number for support.
• Online Chat: Access live chat support at ncpgambling.org/chat.

The sports betting sites we've reviewed are all trusted operators that run legal and legitimate businesses. Specifically, BetMGM and Caesars Sportsbook are two of the largest brand names in the sports betting industry. 

The bigger the brand name, the more bonuses that players can earn, and the higher the customer support and security will be. That being said, all major online sportsbooks are licensed to operate and are regulated by the state they're operating in, meaning they're all trustworthy entities in the U.S. gambling space.

Legal sports betting has never been more accessible, and there have never been more outlets to watch your favorite sports, leagues, and teams. That combination makes it the perfect time for fans and prospective bettors alike to sign up with the top sports betting sites. 

Registration is simple and new players will earn lucrative welcome bonus offers as well as unlimited access to the recurring promotions tailored to the bets you want to place.
