Maryland Online Casinos: What You Should Know About Online Gambling

Are Online Casinos Legal in Maryland?

Online casinos are not yet legal in Maryland. However, legislation has been introduced to allow for a referendum on the November 2024 general election ballot. If approved by voters, online casino games would be allowed in Maryland. 

While you wait for Maryland online casino sites to launch, you can get your fix at tip-top social gambling sites and sweepstakes casinos. Enjoy the same great games you’ll find at legal online casinos in places such as Pennsylvania and New Jersey. The difference is you’ll never lose a dime of real money. In fact, with the sweepstakes casino model, you’ll even have a shot at winning cash prizes. Rest assured, just as you can claim a Maryland betting promo, you will be able to claim a casino promotion when casinos online in Maryland launch. 

Until then, MD online sports betting is available, having launched in November 2022. And with Maryland having a growing scene of land-based gambling, it’s only a matter of time before online casino gambling is legal too.

Will Maryland Online Casinos Offer Bonus Codes?

In the event online MD casinos will launch, you can expect every operator to offer bonus codes to attract new players. Register your account, make a first deposit, then enter a casino bonus code in the box provided. You’ll be able to claim a welcome bonus including a deposit match and free spins to use on the biggest games in town.

Maryland gamblers would have access to some of the best casino bonuses. It's possible to make your online casino gambling go further with a well-timed promotion. Start with a welcome bonus and free spins, then use your winnings to opt in to big-money promotions such as slots tournaments or loyalty schemes.

A welcome bonus is the most common promotion offered. You’ll need to register your account and make a first deposit to take advantage. The casino will credit your online gambling account with funds equal to your deposit.

You’re then free to use your funds on eligible games such as roulette, blackjack or video slots. As long as you meet the playthrough wagering requirements, you can withdraw your winnings plus any free cash awarded by the online casino.

Maryland casinos will also run a full calendar of limited and year-long promotions. Follow up your welcome bonus with a reload bonus or earn free cash by referring a friend to the casino site. You can also join a loyalty program and earn regular benefits such as cashback on losing sessions, bonus spins or holidays.

Most Popular Online Casino Games

Online casinos in Maryland should offer a healthy selection of games to play for free or real money. We suspect you'll need to meet the legal gambling age of 21 in order to play.

Many games will resemble those you’ll find in your nearest Maryland brick-and-mortar casino. However, you’ll be able to enjoy casino gambling at home with higher RTPs (Return to Player percentages) and a wider range of stakes.

Online Slots

Slots are the biggest draw at online casinos. Of the hundreds of casino games on offer, online slot machines will take up the largest share. Choose from penny slots and classic games or go for branded slots that feature exciting bonuses such as free spins.

Under Maryland gambling law, online slot providers will have to be properly licensed and regulated by the state’s gaming commission. That means you can spin in comfort with the knowledge that every game is fair and transparent.

Potential online slot providers in Maryland:

• NetEnt
• IGT
• SG Digital (inc. WMS, Bally, Barcrest)
• High 5 Games
• Ainsworth
• Konami

Progressive Slots

The beauty of casino gambling is that you have a chance of winning real money. Progressive slots, meanwhile, give you the opportunity to win serious life-changing sums of cash.

In a progressive slot, a small percentage of each bet contributes toward a bigger jackpot. The jackpot increases with every contributing wager. It only falls when a player triggers a bonus game or activates the jackpot at random.

The longer a progressive jackpot goes unclaimed, the bigger it can get. Some of the largest jackpots won at online casinos have easily reached six and seven figures.

Online Poker

The current rules for online gambling in Maryland don’t cover poker sites. However, if casino gambling is legalized, you can bet your bottom dollar that online poker will be too.

Hit the online tables to play Texas Hold’em or Omaha in a variety of cash games and tournaments. It’s just like playing at the MGM Harbor, but you never have to leave your own home!

In addition to cash games to suit your budget, you’ll also be able to jump into online satellites where you can secure your spot into the World Series of Poker and other huge live tournaments.

Online Blackjack

Casino gambling isn’t all about slots; you can also play great games such as blackjack. It’s just against the dealer as you try to reach 21 without going bust. Blackjack is easy to learn and offers Maryland residents an excellent house edge at the casino.

In addition, top online casinos should offer a range of interesting blackjack variants, such as classic blackjack, Atlantic City Blackjack with the surrender option, and Perfect Pairs with fun side bets.

Online blackjack variants:

• Classic Blackjack
• Atlantic City Blackjack
• Live blackjack
• Multihand Blackjack
• Super Fun 21
• Zappit Blackjack

Online Roulette

Online roulette is one of the easiest casino games to learn and play. Plus, you’ll be able to gamble online at stakes much lower than you’ll find at the Horseshoe or Riverboat on the Potomac.

In online casino roulette, you bet on numbers from a choice of 38. You can also bet on colors or groups of numbers. Once bets have been placed, the roulette wheel spins and comes to a stop at random. The whole process is computerized and governed by a random number generator (RNG).

Maryland online casinos will offer a range of different game flavors, including American Roulette and French Roulette. That’s something you just won’t find in your local Maryland casino. Plus, the benefit of European Roulette and French Roulette is that they boast a smaller house edge than traditional American Roulette.

Popular online roulette games:

• American Roulette
• European Roulette
• French Roulette
• 100/1 Roulette
• Live Dealer Roulette
• Bonus Roulette

Live Dealer Games

Live dealer games are unique to online casinos. Play one-on-one against a human croupier beamed in live via webcam. You place your bets in the normal way using your keyboard and computer. However, every card dealt and roulette wheel spun is 100% real!

Every good online casino in the US now offers a host of live dealer games including baccarat, blackjack, and roulette. You can also bet on a prize wheel in games such as Dream Catcher and win big cash prizes.

Popular live dealer casino games:

• Live roulette
• Live blackjack
• Live baccarat
• Lightning Roulette
• Dream Catcher
• Live Three Card Poker
• Live Sic Bo

Other Online Casino Games

Once Maryland online casino sites are finally active, you’ll likely have access to some alternative games such as keno and bingo.

Online keno works just like your favorite games at Rocky Gap or the Horseshoe Casino in Baltimore. Choose your numbers and win money if you match the numbers drawn out at random.

Every legit online casino in the US also provides video poker games from leading manufacturers such as IGT. It’s just like playing your favorite 5-card draw machines in the casino but you never have to leave home! Choose from Deuces Wild where twos act like jokers and boost your coin bets to have a shot at the biggest jackpot.
