For now, I don't have any rituals when gambling or before betting, but the thing I often do before gambling is to do a little stretching, and sometimes I do jumping exercises first (sometimes, I do skipping). In the past, I had a ritual or superstition when gambling, at that time I held a doll, and said that it could bring good luck, lol, but I did it for fun or excitement only, not really believing in it, because I did it when I was with my friends. By the way, I think almost all gamblers have done the same or similar thing as I did, because every gambler I have ever met has done it too, just my opinion.
