Special shoos allow the dealer to draw one of several cards. Of course, such a trick is unlikely to go unnoticed by professionals, but it's fine for amateurs. The same goes for so-called croupier mistakes, which usually result in the casino not making any payouts. This is the roughest way, but even it can be encountered. That is why I prefer online casinos. There is no fraud there. The main thing is to choose a site with a high rating. For myself, I chose https://wildcardcity.net/bonuses. There are a lot of bonuses and a huge selection of games.
