But if you think a large and publicly traded company is going to be honest, think again. I’m not saying William Hill are the worst, because there are many other casinos that do far worse to players, and more frequently. Is there a way to win at William Hill Casino? Many players have won with the cross reference system (best winning roulette system) only to be told by William Hill they wont be paid winnings. The complaints are mostly for plain payout refusal. I get more complaints about William Hill than any other casino. So you want to know how to win at William Hill casino? Ok, if you haven’t already deposited your money, don’t do it.
