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.
It would have been better if you told your friend to teach you the pattern he is using, for him to be predicting it more accurately it means he has been studying that Casino and probably knew some secret. If you had made up your mind and ask him, maybe he could have opened up for you perhaps you wouldn't have been asking us here to know while you already have a friend who can help you with what you needed.
For me I don't have a strategy or a particular pattern maybe I could be like you also who don't have a pattern.
