Suspicion will always be there, that’s unavoidable. But proving a game is rigged? That’s nearly impossible. So here’s what I do to minimize the risk: I only play at reputable, regulated casinos. At least with proper oversight, regulators audit their games regularly to ensure fairness and prevent cheating. It’s not foolproof, but it’s the safest way to gamble.
Having suspicion is a normal thing especially when you're on a losing streak, you can always suspect manipulation but when there's no how to prove it you'll just relax. At times like that I always remind myself about the house edge that casinos have to take our money more than they give out to remain in business. Exactly, to minimize the risk of manipulation it is best to gamble in reputable and regulated casinos, atleast we're sure that we're depending on luck to win. I believe that regulated casinos should have external officials that audits them, it'll be in the interest of gambling
