While casino games are not really prone to analytical thinking, your ability to include this as part of your strategy can be very helpful. You don’t have to be an analyst as such but you should be able to analyze what you plan to do before you actually do it. Look at the slot machine and analyze the last places it landed—what can you do no to assure you will win? Should you increase your bet? Should you increase or decrease the number of lines you are playing? All of these factors are part of the analytical structure and can be helpful in providing insight into the move you should make.
Games of chance can never be pre-determined but you can follow a machine and gather some kind of idea about how it is operating at any given time. If you play a certain number of lines per bet is it more likely to land on winning spots for you? How often can you expect to win in a given night of playing? Learn to think about what you do before you do it and you will improve your winning streak.
