Each of the best online sportsbooks offers something a little different when it comes to welcome bonuses. When you use the BetMGM deposit bonus code, you’ll have a shot at a ‘second-chance’ bet where you can get up to $1,500 back in bonus bets should your first wager lose.

The FanDuel promo code, DraftKings promo code, and bet365 bonus code all feature the popular ‘bet and get’ promotions, similar to BetMGM's new-user offers in Michigan, New Jersey, Pennsylvania, and West Virginia.

The Caesars Sportsbook promo code rewards you with 100% profit boost tokens, which can be used over your first 20 bets. Last but not least, the Fanatics Sportsbook promo gives you up to $2,000 in FanCash when you bet for 10 consecutive days after creating your new account.

To claim the BetMGM new-user promo, you must be physically located in a licensed state, as the offer may vary by location. Notably, the BetMGM new-user promo is not available to customers in New York.

With the Missouri sports betting launch set for Dec. 1, 2025, you can expect BetMGM to be among the online sportsbooks offering Show-Me State bettors generous welcome offers.

While BetMGM Sportsbook is a trusted platform, there are certain sportsbooks to avoid — make sure to stick with reputable options for the best experience.

🔎 BetMGM pros and cons  

📝 User reviews 

BetMGM maintains quality ratings from both Apple and Android users in the U.S. The app's positive highlights include a diverse range of betting markets, a user-friendly interface, and numerous ongoing promotions, making it one of the best sports betting apps in the industry. Many users also claim that it's one of the best parlay betting sites available.

Some notable knocks against BetMGM (particularly from Google Play users) are a lack of competitive odds at times, hit-or-miss customer service, and struggles with the verification process.

App Store: 4.8/5 ⭐ (237.7K reviews)

Google Play: 4.2/5 ⭐ (36.2K reviews)

💳 BetMGM payment methods 

The payment methods at BetMGM vary between states, but most of the popular options, like Visa, Mastercard, PayPal, and debit cards, should be available wherever you are located. We've deposited countless times with a debit card, and the money is always loaded into our accounts instantly.

Furthermore, when we've made withdrawals, our funds have been delivered faster than the website suggests, making it one of the best online sportsbooks for payouts in the country. A debit withdrawal can sometimes take just an hour or two, while PayPal is usually within 24 hours, in our experience.

ⓘ Customer support 

Contacting BetMGM customer support will be different in every state. You can click here to find the phone number, email address, and service hours for wherever you are betting. However, most might find that the live chat option on the BetMGM contact page is the best choice.   

When we tested it out, a support representative was available right away and solved our question within a few minutes. It was amazing to be able to talk to a real person rather than have a bot direct us to an article that may or may not solve our issue. This feature is available 24/7, making BetMGM’s customer service a standout in the industry.

💵 Types of sports bets 

Whether you're checking out New York sports betting apps, NC sports betting apps, or anywhere else, you’ll likely be able to find any sports betting market you’re looking for at BetMGM, including same-game parlays, player props, alternative lines, and more. If you’re new to sports betting, check out the list below for an explanation of the most popular types of sports bets.  

Moneyline 

A moneyline bet is the most basic wager in sports. Each team will be assigned odds such as +100 or –110, and your job is to pick the winner. The favorite will have the minus sign (-) in front of the handicap, while a plus sign (+) indicates an underdog.

Example:

• New York Rangers +125 vs. Colorado Avalanche -115

Point spread 

Sometimes, moneyline bets can involve extreme odds, like –800 for a heavy favorite. If you’d still like to bet on the favorite but want better odds, you can lay the points with the point spread. You'll find plenty of opportunities at the best NBA betting sites.

Example: 

• Green Bay Packers +3.5 (-110) at Detroit Lions –3.5 (-110)

A $100 bet on either would net you the same result of $90 profit. If you took the Lions, they’d have to win by 4+ points, and if you backed the Packers, they could lose by up to 3 or win outright. 

Over/Under (totals)

An Over/Under bet is simply betting over or under the total points that the sportsbook has assigned to a particular game.  

Example:

• Seattle Seahawks vs. San Francisco 49ers: Over 44.5 (-110), Under 44.5 (-110)

Props 

Props are hugely popular among sports bettors and a great way to get in on action that isn’t tied to the final score of a game. At BetMGM, you’ll be on one of the best prop betting sites and find extensive markets like NBA props, anytime touchdowns, home runs, and three-pointers, along with game props like first-half totals, the first team to score, and more.

Example:

• Steph Curry points + assists: Over 35.5 (-110), Under 35.5 (-110)

Futures  

Futures bets allow you to put cash down on results that will happen down the line. At BetMGM, you can bet on Stanley Cup odds, NBA Championship odds, Rookie of the Year, MVP, Offensive Player of the Year, and plenty more. Some bettors like futures because of the enticing odds, but others don’t like their money to be tied up throughout the season. 

Example: 

• Ashton Jeanty to win Rookie of the Year: +250

Live bets 

Live betting is all the rage these days in the sports betting world, and it’s rare to find a book that doesn’t offer it. It’s a great option for those who want to stay engaged all game long and place wagers on up-to-the-second odds on moneylines, point spreads, Over/Unders, props, and more. 

➕ Odds pricing 

It’s always a good idea to sign up for multiple sportsbooks. Not just for the welcome offer but for the ability to odds shop for the best line. While the big books tend to be fairly similar, it’s not uncommon to find line discrepancies. This can make a significant difference to your return, especially if you’re betting a large sum. Overall, BetMGM odds have always seemed fair to us, and we've often found better-than-average prices on MLB player props.

🏆 Sports available 

BetMGM outshines most of its competitors in terms of sports variety and is recognized as one of the top NFL betting sites and college football betting sites. Of course, you’ll find the staples like:

🏈 NFL

🏀 NBA

⚾ MLB

⚫ NHL

👊 UFC

But if you want to dive deeper into the more obscure realm of sports betting, you’ll be able to throw down on everything from cricket, curling, biathlon, Gaelic games, darts, snooker, and even surfing.  

🚨 Bet limits 

As with any sportsbook, BetMGM Sportsbook has the right to limit the wagering amount of big winners. These are often professional bettors, also known as 'Sharps' or 'Wise Guys,' and it is BetMGM’s sole discretion to limit who and the amount. For more information, consult the terms and conditions or customer support in your state. 

BetMGM has entered the Missouri sports betting market as sports betting officially went live on Dec. 1.

Missouri users can now register on the BetMGM app. Once you register and have funded your account, you can take advantage of multiple Missouri sports betting bonuses, including a lucrative BetMGM Missouri bonus code, worth up to $1,500 in bonus bets.

Combined with strong partnerships (including a local tie-up with Century Casinos) that pave the way for both online and retail operations in the state, Missouri bettors will have access to lots of great promos from the start. We love that the sportsbook has come out firing and is also offering Missouri bettors $100 in Kansas City Chiefs team store gift cards with qualifying bets. 

If you’re comparing options in Missouri, don’t forget to check out the DraftKings Missouri sign-up bonus, Fanatics Sportsbook Missouri promo, the FanDuel Missouri promo, and the Caesars Sportsbook Missouri promo code offer to see what new-user offers are available.

BetMGM Casino is an online gaming arm of BetMGM, offering a wide range of digital casino games, including branded slots, table games like blackjack and roulette, live dealer experiences, and exclusive in-house titles.

The platform works much like a physical casino: you create an account, deposit funds, and then play for real money or in demo mode, with all games run by licensed software providers to ensure fairness.

The BetMGM online casino is legally available in states where online casino gaming is regulated, including BetMGM Casino NJ, BetMGM Casino PA, BetMGM Casino Michigan, and BetMGM Casino WV, with additional states expected as legislation expands.

BetMGM casino is fully integrated with the BetMGM Sportsbook app in supported markets, so players can seamlessly switch between sports betting and casino play using a single account and wallet.

Every sportsbook brings something unique to the table, but the BetMGM Sportsbook promo shines for newcomers with its generous welcome offer and great referral bonus, giving fresh bettors a smooth and rewarding way to jump in.

BetMGM takes the spotlight with its standout referral program, giving players real rewards just for bringing friends along. While DraftKings keeps fans busy with daily promos and contests, and Caesars draws attention with its perks-packed loyalty program, BetMGM makes earning extra value effortless through simple, shareable rewards.
