However, I wasn't focused on what he was doing; I felt it was all about luck, so personally, I just played slots without paying attention to any particular patterns. So, what about you? Are you one of those people? or are you just a casual player like me? If so, please give your reasons.
There's no pattern, if he feels there is a pattern and it works, it's just a suggestion from his brain. CMIIW, slots use a system called RNG. The symbols that appear are randomized before being presented to the user. There's no predictable pattern. Even if the pattern he uses works, it's a matter of luck. I once tried a pattern, and people says its a effective pattern to get free spins, but after I followed it, it didn't work as instructed. From there, I stopped believing there were hidden patterns in slots.
