As with any game of pure chance, there is no real effective strategic system for winning at slots. You will probably, of course, encounter someone who claims to have developed thefool-proof' slots strategy system but please, ignore such advice. The game is random and arbitrary. The machines have no memory, so there is no effective way of outsmarting them. But there are some tips, which you can use as a basic strategy. You should always be looking for the machines that have the highest payout. You want to find anything above 95%. Similar to other casino games, it is crucial to know the odds and probabilities of the machine you're playing. Make sure you know the payout schedule before you start pumping in your virtual coins. Determine your losing limit for the day. Once that limit is reached, go do something else. You will not be a winner every time you play. The machine will not feel bad if you spend a lot of money and don't get anything back. Try not to spend all of your time on a machine that isn't paying out. When things are going your way and you're on a lucky streak, take advantage of it and bet more. When you're slumping, bet less. Find a machine that suits your bank-roll. 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.

Slots shouldn't be a stress for you, just enjoy. If you feel lucky increase your bets and vice-versa.
