The rules for gambling have already been laid down. But these codified rules need a bit more of explanation to give the players better insights on what they are about to undertake.
Always keep in mind that the fact that you are having fun is the most important aspect of gambling. In fact, you are probably in for the game because there is much fun that the place could give you. It is just like playing for a movie or a game of football for a few bucks. Think of winning as an added incentive and not as the sole purpose of gambling.
Some are made to win, some are made to lose. When you place your foot inside that casino and started to gamble, you accept the fact that you could lose money. The chances of winning in different game vary, too. Some may have higher chances while others have close to none at all. The casino can't let all of the visitors become winners because they will go bankrupt and would soon have to close down. You don't want to lose such a place, do you? Plus, putting a high expectation of winning will just get you frustrated. Besides, it is not supposed to be your source of income. You have your job for that.
Discipline yourself. Control is what it takes to walk away from the casino without your car or jewelry taken off from you that same night. When you don't win for that night, don't make matters worse by taking all your money out of the bank to gamble some more. Better yet, leave all other sources of money aside from what you are ready to lose for that night. Don't even pawn a possession because you can never trust the other players to give it back to you especially if you don't know them that much. Remember that even people with bad intentions are allowed to go inside the casino.
Gambling is still gambling no matter how you shake it. It will have its own sneaky tricks that you have to be careful of. Also, keep in mind that there are gambling protocols that each and everyone have to follow for themselves and for other players. It will help everyone else enjoy the night of playing and make the experience worth all the winnings and losses. Try to be a better player by keeping all these in mind.
