My religion sees gambling as unethical. It's not forbidden but it is frowned upon by the leadership of my religious organisation. So I grew up in a home that had no belief or superstition about gambling. I left home and started gambling but never had any belief that some rituals or traditional practices could bring gambling wins or success. Besides skills and luck, I don't have any other belief about gambling. And I don't perform any rituals before, during or after gambling.

But I have heard that some people visit traditional doctors for luck charms. I can't attest if these charms are potent or not.
