There is hardly any strategy that can be applied to slots. Never believe if somebody says that he has an incredible winning strategy. The machines have no memory, so there is no effective way of outsmarting them. The strategy can be represented only by a number of tips. Try to play slot machines that have the highest payout. Try to find something above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. Before you start playing slots get acquainted with the payout schedule. Before you start playing set for yourself a losing limit. Once that limit is reached, go do something else. When playing remember that you can win as well as lose. The machine will not feel bad if you spend a lot of money and don't get anything back. If you think that the machine you are playing will hardly pay anything out you’d better stop playing it. When things are going your way and you're on a lucky streak, take advantage of it and bet more. Don’t make high bets if you are not very lucky with this very slot machine. Choose a slot according to your bankroll. Look for a dollar machine, and have some fun. Don't forget to cash out the credits you've accumulated. Sounds obvious, but a lot of people forget! Always play what you know.
