How We Ranked MD Online Casino Sites
Safety & Licensing
The first thing we check regarding Maryland casino sites is the licensing section. We only approve online casinos that are SSL encrypted and licensed and regulated by reputable authorities like the CEG or the MGA gaming control agency. Responsible gambling tools are also a must in our book.
Online Casino Games & Payout Rates
We check all Maryland online casinos for game variety and RTP rates, from classic online slots to live dealers and table games like European Roulette or Texas Hold’Em. All online casino games must be sourced from reputable studios that undergo regular fairness audits. If a platform offers online sports betting options for Maryland bettors, that's an added bonus.

Why Is Slots of Vegas the Best Maryland Online Casino?
There are several reasons why Slots of Vegas is the No. 1 Maryland center for online casino gambling. Here are just a few of them.
Excellent RTP Rates: Slots of Vegas hosts all the latest and greatest slot machines from RTG, a highly reputable studio known for a mix of high payout potential and RTP rates that regularly exceed the 96% industry average.
100% Mobile-Friendly: Slots of Vegas is optimized for instant play on all iOS and Android mobile devices. This means access to all online slots and table games from the desktop version.

These features are the reason why it’s also popular among online gambling sites Florida players recommend.
Why Should I Use Online Casinos in Maryland?
Compared to retail sports betting and land-based casino operators in Maryland like the Hollywood Casino Perryville, the Horseshoe Casino Baltimore, or the MGM National Harbor Casino & Hotel Maryland, MD online casinos have a host of benefits that put them on another level. Check this out.
- Bigger Bonuses: Thanks to lower overhead costs, Maryland online casinos and sports betting sites can use the extra money to increase their bonus deals. An $8,000 welcome bonus with 300 spins is something land-based casinos like Live Casino & Hotel Maryland or the Horseshoe Casino can only dream of.
- Better Payout Rates: Again, thanks to less overhead, Maryland online casino sites can boost their RTP rates and effectively increase win potential compared to traditional casinos like the MGM National Harbor.
- Thousands of More Games: Due to physical constraints, it's very hard for brick and mortar casinos like the Horseshoe Casino Baltimore or MGM National Harbor to offer 1,500+ games. Yet, these numbers are perfectly normal at Texas online casinos like Super Slots.
