Best Maryland Online Casinos in 2025

One of the first things to ask before signing up is, “Are online casinos legal in Maryland?” In this section, we’ll answer this question, highlighting what the law says, the legal age for gambling, possible restrictions, and how taxes work for players.

Gambling laws (online casino)

Currently, online casino gambling is illegal in Maryland. This may come as a surprise to many, especially since other forms of gambling, like land-based casinos, lottery games, sports betting, and charitable games, are all allowed. The reason is simple — the House of Delegates didn’t pass the bill to legalize it. So, while there’s hope that the law might change soon, you can explore options in nearby states, like online casinos in Delaware.

Gambling Age 

In Maryland, the legal age for gambling depends on the activity you’re involved in. The law states that you must be at least 21 to play at a casino or engage in sports betting, while the minimum age for lottery games and horse racing is 18. 

Tax

Taxes are another key part of the conversation around online casinos legal in Maryland. Hence, if you win over $5000 at a casino or through a sportsbook, a portion may be withheld for both state and federal taxes. If you’re a resident of Maryland, you’ll pay an 8.75% tax rate on those winnings, and if you’re not, your winnings will be taxed at 7%.

Our page has a smart filter tool that lets you sort the best Maryland online casinos based on the features that you consider most important.

As we mentioned earlier, we don’t just add random sites to our list on this page. Every MD online casino goes through a detailed review, during which we check features that actually affect your play. This is to ensure that you find quality options that meet your needs. Below is a list of the features we consider:

• License. Since there are no Maryland licensed online casinos, checking for a license is usually our first step in reviewing an offshore casino site. We make sure that the casinos allowing US players on our radar have a valid license or strong regulatory oversight before listing it.

• Casino Reputation. Our team evaluates the overall reputation of each site. We check if the casino is trustworthy, how it treats players, its performance, and whether it delivers on its claims. We only consider casinos that have a solid track record.

• Check T&Cs for Maryland Players. Every casino has its guidelines, so we review the terms for online casinos that accept Maryland players. The purpose of this is to help us catch any restrictions or rules that could affect your play before you even sign up.

• Casino Games. This is the highlight of any site, which is why we only list sites that offer a large game library. Not just that, we also consider the game developers, the quality and fairness of the games, and even free casino slots for fun.

• Available Payment Methods & Limits. Payments are a big part of your gaming experience, so we check if a Maryland online casino offers secure and flexible options. Similarly, you’ll find only sites that support a decent deposit and withdrawal limit for players in the state.

• Bonuses for Maryland Players. We look into the kind of bonuses that each casino offers, from welcome offers to free spins and loyalty perks, and how fair the terms are. We also check if Maryland players can claim the bonuses listed before we add them to this new online casino list.

• Responsible Gambling Tools. Your safety is our priority, so we always look for casinos that provide tools to promote safe gaming. This makes Maryland online casinos with deposit limits, self-exclusion tools, and timeout features our best options.

• Customer Support. This is another key feature. We check if the casino online MD has a support system. Our team also assesses the communication channels available to Maryland players and how responsive the support team is.

• Mobile Friendly. The world is already at a stage where technological progress is a priority. Therefore, SlotsUp will only consider a site that runs smoothly on mobile devices.

Even though online casinos are not regulated in Maryland, you can still enjoy the thrill. Other types of casinos welcome players from the state with open arms. They are:

Offshore casinos

These casinos operate outside the US but still allow for real money stakes and wins. You’ll find the best online casino that accepts MasterCard deposits under this category. Offshore casinos are usually not governed by US laws, which may be a concern for Maryland players.

Sweepstakes casinos

Sweepstakes casinos use a coin-based system, where you can buy or acquire sweepstakes coins or gold with real money or promotions to play games. You can redeem winnings for real cash, but the casinos are limited in scope due to their affiliation with social media or promotional platforms.

Social casinos

In social casinos, players use virtual currencies or chips, often purchased with real money to play games. Thus, these casinos are known purely for entertainment. While this approach minimizes risk, remember that a Maryland virtual online casino won't offer real money games or cash payouts.

A real money online casino in Maryland supports familiar payment methods for seamless transactions. They include:

• Debit Cards. This payment method allows you to fund your account directly from your bank. It is safe and widely accepted, but large transactions may be blocked or delayed by the bank or site.

• Credit Cards. Online casinos in Maryland allow players to use their credit cards to borrow funds from their card issuer to make deposits. However, it may come with extra charges.

• eWallets. Payment methods like Skrill, Neteller, and PayPal are popular at online casinos for their speed and security, but some casinos may have limits on withdrawal amounts.

• Crypto. You can also find crypto options like Bitcoin, Ethereum, and Litecoin at the best casino. They allow for anonymity, but values can change drastically due to their volatility.

If you want to go through the search process yourself, that's perfectly fine. We’ve compiled a list of essential factors to help you find the best trusted online casino.

1. Check if casino available in Maryland. The first thing to check is whether it’s an online casino for Maryland players. If it’s not available in the state, you won’t be able to register, let alone play any game.

2. Check casino reputation. Use player ratings and feedback to check if the site has a good reputation. You can also rely on expert pages to determine if it is worth your time and money. 

3. Check T&Cs for players from Maryland. Review the terms and conditions to see what rules apply to Maryland players. Pay attention to activities that may affect your accessibility to avoid unpleasant surprises.

4. Check payment limits. Make sure to confirm the deposit and withdrawal limits. This includes how much you can withdraw per time, whether from your bonus rewards or winnings. This is important because the limits may vary between casinos.

5. Check bonus T&Cs. After you’ve confirmed the bonuses available to you, review the bonus terms. You should look out for details like wagering requirements, validity period, and eligible games to fully maximize your bonus.
