On this roulette sim once you press the 'rated game' button you'll be given $3k to bet and your game will be recorded step by step bet by bet without you being able to delete it, unless you delete your account and start again.
There's people who only post there winnings on youtube, with this sim you can't, once committed to the 'rated game' mode your videos can be made public or private to members only.
There's no reason a site like this would manipulate spins
