Maryland Casino Guide

Maryland has half a dozen land-based casinos, which is not bad for a state that size. It also has a state lottery, which can be a good sign of openness toward online gambling. In fact, Maryland seems poised to legalize online sports books, although moves towards online casinos are less promising.

Online Casinos in Maryland

Maryland has not legalized online casinos yet.  

Compared to other states in America, Maryland isn't opposed to the idea of gambling completely. Maryland is home to a handful of casinos so if more states begin to pass bills in favor of online gaming, there is potential for Maryland to do the same. 

In fact, there are currently moves toward legalizing at least sports betting in Maryland. As neighboring Pennsylvania, Delaware, and West Virginia have all legalized both online casinos and sportsbooks, there may be pressure to do the same in Maryland.

History of Gambling in Maryland

Maryland has had a rather slow-paced growth of gambling. Although horse racing was legalized in the twenties, table games weren't made legal until 2012. 

But this late legalization of table games may carry some momentum toward legalizing online gambling in the state. 


Timeline of Legal History of Gambling

  • 1791 Lotteries for churches and public improvement are legalized
  • 1920 Horse racing given state oversite
  • 1943 Slot machines allowed in some counties
  • 1973 State Lottery starts.
  • 2008 Slot machines approved for some private venues
  • 2012 Casino table games legalized

The minimum gambling age is 21 for playing at all Maryland casinos and is 18 for pari-mutuel wagering and bingo. Smoking is prohibited in all Maryland casinos.

Payback Percentages

No public information is available about the actual payback percentages on electronic gaming machines at Maryland casinos. However, gaming regulations require a minimum payback of 87% on any one machine and all machines within a casino must have an average payback of 90% to 95%. Unlike Maryland, in many states the slot machine payback statistics for that particular state’s casinos are released as a matter of public record.

Gambling in Maryland Today

There is significant reason to expect to see online gambling legalized in Maryland in the near future. As mentioned, as neighboring Pennsylvania, Delaware, and West Virginia have all legalized both online casinos and sportsbooks, we may expect the same in Maryland.

Additionally, a 2018 bill called for the formation of a task force to “study the implementation of sports gaming in the state." So online sports betting is likely in a relatively short time. The hope for us casino fans is that online casinos will be included in any legislation.
