~ But some casinos do sometimes take it too far and lower your odds of winning even more without giving you notice, but this will usually only happen to unregulated casinos which have their headquarters in some corrupt third world country. Luckily, with some DYOR, that can be easily avoided.
It's forbidden by regulators to do it. A company of the level of Evolution will certainly not lower your odds without a notice. There so many regulated casinos that I don't know why some people are still playing on unregulated ones. Is it the "profitable games" they are attracted to? Unbelievable bonuses? It's their own fault they are scammed then.
