In order to stay and survive in gambling world, a gambling site should be trustworthy. If they will fail to secure their players, then they should expect that sooner or later, little to no one would trust and play in their site. We're all aware that the house, most of the time, is at an advantage. This is for them to profit. Which is why there is something called rtp rate. A casino shouldn't rely on dirty tactics such as cheating just to ensure a profit out of it.
Every casino and gambling website wouldn't really give out their software and algorithm for security purposes. It should be kept hidden and unknown so that it won't be abused by the players. Because of course, once people knew how things work, they will come up with a plan to utilize it to their own adavantage. Even if it means to cheat on the house. After all, some players are just after the money. Perhaps players could just find provably fair based casinos and check the reviews about them to countercheck whether it's realiable or not.
