I don't know if someone have posted this because I couldn't read all the responses but when I love gambling with dice with my friends way back, we don't share the same dice. We believe that if I use the same dice that you are using, it will bring bad luck from you to me and for that reason we all have our separate dice that we use when gambling. It's very funny Lolz, gamblers can come up with nonsense thoughts when gambling and why is it like that.
