1. You should start by choosing the best online casino. Do not register with the first online casino that you see. Check out their terms and conditions. A good online casino would have low restrictions on payout, good bonuses, and an excellent customer service. If the online casino offers free slot games, it is good to try their interface first. You wouldn't want to play long hours on a crude interface.

2. After you have chosen your online casino, decide on how much money you are willing to lose. The keyword here is lose -- you should always assume that your bankroll is lost money, and profit from your winnings is a different thing altogether.

3. When you have decided on how much your bankroll would be, try to split it into several clusters. This is to enable you to play more across several sessions. Pouring all your money into one big session would encourage you to deposit another batch the next day, and that means big losses.

4. Stick to your budget for the session. If you are on a losing streak, don't even thing about using your remaining credits to play more.

5. Save your winnings, however large it may be. Even if you win a huge pot, exhaust your initial bankroll first before you re-bet any of your winnings.

6. It would help if you would assign a win goal. This is how much you would like to take home for the day. Be realistic -- assume that you won't profit. A good win goal is somewhere 50-60% of your initial bankroll. If you manage to have something in excess to this percentage, you can re-bet the excess.

7. If you are tired and frustrated, stop playing. Oftentimes, you'll play and spend more than you need to because of frustration and stress. Take a walk, eat, sleep and return to your computer once your head has cleared up.

Remember, a solid strategy in slots is to have enough discipline to know when to stop. There's no other strategy better than controlling your money.
