To be fair on known scammer 1xbit. They are not proven cheating against players using rigged games since they are just using 3rd party games like the other casino. They are known scammer for holding users balance and all their scam accusation case doesn’t related to cheating games.
I think there’s no known case in regards with the games on all existing casino except for those house game which is verifiable via hash seed. But the rest of the games of casino nowadays is close source which means you can only prove that they are cheating if you examine physically their machine or the provider release the source code of the game.
since it would be a closed source. There's no way for an individual to point some fingers that they were really that rigged or not fair without having those evidence which is really a normal approach.
This is why there's nothing we can do but to embrace out on what are the outcomes.
In regarding about 1xbit then this is a platform on which they do held up their users funds and not on the games itself which it do makes them shit. About those roulette possible
rigging up then there's no way on proving it out when you are inside of a casino on which there's no way for us to point out fingers even if we do feel out there's something wrong.
