Also there is one thing that confuses us a lot, which we hope someone could give us an hint.

If an experienced gambler like OP can win stably in certain games such as the BGAMING slot ones, he could do so in big casinos such as stake.com or roobet.io,

those are many credited casinos out there and clearly he knows them too.

But why he toured around different casinos to play the same slot games?

From his posted history we can see him betting on a lot of smaller size of casinos like owl.games (we are indeed a much smaller casino comparing to the big ones)

We could not understand why to be honest.
