There is only ONE strategy that works every time. Take only the money you can afford to lose. Call it entertainment expense. Parse the amount over the amount of time you will spend at any one casino so you have enough to make it fun. Be prepared to lose it all. If you walk away with money, GREAT! If not, you had a good time - just as if you went to a movie. During slots sessions, it does make sense to have win goals and loss limits. It is fun to walk away up (or not all the way down). In any case, gambling should be for entertainment purposes only. Casinos are a for profit business. No one can beat them or they would be out of business. Have fun, stay disciplined.
