According to Mississippi State law, as long as you play games of chance in a licensed establishment like a casino, riverboat or on tribal land, you are welcome to gamble legally in the State of Mississippi. The code states:

If any person shall encourage, promote or play at any game, play or amusement, other than a fight or fighting match between dogs, for money or other valuable thing, or shall wager or bet, promote or encourage the wagering or betting of any money or other valuable things, upon any game, play, amusement, cockfight, Indian ball play or duel, other than a fight or fighting match between dogs, or upon the result of any election, event or contingency whatever, upon conviction thereof, he shall be fined in a sum not more than Five Hundred Dollars ($ 500.00); and, unless such fine and costs be immediately paid, shall be imprisoned for any period not more than ninety (90) days - MS Code § 97-33-1 (2013)

Outside of these requirements, all other gambling is considered to be illegal and could leave you to face prosecution in the court of law.

When it comes to sports betting, no online options are legally available to you however, you are welcome to participate while at a licensed casino.

The law also seeks to stifle illegal gambling institutions with the view of preventing organized crime - Section 87.1.1.

Section 87.1.5 allows for losers in licensed gambling establishments to sue the person, company or owner where the loss took place.
With the number of legal gambling venues available within the state, there is really no reason to play games of chance illegally. It isn’t worth the risk and the State of Mississippi has gone out of their way to make sure you have access to every possible casino game you can think of.

The State of Mississippi has written laws to protect its citizens. It has the view of gambling as a healthy pastime and American tradition which should be allowed to continue within carefully controlled boundaries.
Whether these boundaries make you feel stifled or not is all up to your perception of the situation.
