There is no details to check about the roullete provider. Evolution games doesnt have this roullete game.
Who provided that?
Why do you think there has to be a game provider? It could be a roulette game that's custom-made or in-house.
But, the way it looks to me, the design seems like a low-budget script that you can find on marketplaces like CodeCanyon. Definitely something to avoid.
Have you checked their games? The games are broadcast from a real casino with real people betting.
Who ever is the provider is also a casino operator with people play there 24/7
There are 4 different roullete games and the provider hire people 247 to move the roullete.
Things like this have huge costs I dont believe he does anything on his own.
